- #  Each User may also freely distribute the Program, whether in its

- #  jurisdiction over the User or the intended distribution itself.
- #
- #  NO WARRANTY
- #
- #  The program was produced on an experimental basis in the course of the
- #  research and development conducted during the project and is provided
- #  to users as so produced on an experimental basis.  Accordingly, the
- #  program is provided without any warranty whatsoever, whether express,

- #  any right of any third party.
- #
- #  Each user of the program will agree and understand, and be deemed to
- #  have agreed and understood, that there is no warranty whatsoever for
- #  the program and, accordingly, the entire risk arising from or
- #  otherwise connected with the program is assumed by the user.
- #

- #  regardless of whether they have been advised of, or otherwise had
- #  knowledge of, the possibility of such damages at any time during the
- #  project or thereafter.  Each user will be deemed to have agreed to the
- #  foregoing by his or her commencement of use of the program.  The term
- #  "use" as used herein includes, but is not limited to, the use,
- #  modification, copying and distribution of the program and the
- #  production of secondary products from the program.
- #
- #  In the case where the program, whether in its original form or
- #  modified, was distributed or delivered to or received by a user from
- #  any person, organization or entity other than ICOT, unless it makes or

-5. Time Zone Database
-
-  ICU uses the public domain data and code derived from Time Zone
-Database for its time zone support. The ownership of the TZ database
-is explained in BCP 175: Procedure for Maintaining the Time Zone
-Database section 7.
-
- # 7.  Database Ownership
- #
- #    The TZ database itself is not an IETF Contribution or an IETF
- #    document.  Rather it is a pre-existing and regularly updated work
- #    that is in the public domain, and is intended to remain in the
- #    public domain.  Therefore, BCPs 78 [RFC5378] and 79 [RFC3979] do
- #    not apply to the TZ Database or contributions that individuals make
- #    to it.  Should any claims be made and substantiated against the TZ
- #    Database, the organization that is providing the IANA
- #    Considerations defined in this RFC, under the memorandum of
- #    understanding with the IETF, currently ICANN, may act in accordance
- #    with all competent court orders.  No ownership claims will be made
- #    by ICANN or the IETF Trust on the database or the code.  Any person
- #    making a contribution to the database or code waives all rights to
- #    future claims in that contribution or in the TZ Database.

-5. Time Zone Database
-
-  ICU uses the public domain data and code derived from Time Zone
-Database for its time zone support. The ownership of the TZ database
-is explained in BCP 175: Procedure for Maintaining the Time Zone
-Database section 7.
-
- # 7.  Database Ownership
- #
- #    The TZ database itself is not an IETF Contribution or an IETF
- #    document.  Rather it is a pre-existing and regularly updated work
- #    that is in the public domain, and is intended to remain in the
- #    public domain.  Therefore, BCPs 78 [RFC5378] and 79 [RFC3979] do
- #    not apply to the TZ Database or contributions that individuals make
- #    to it.  Should any claims be made and substantiated against the TZ
- #    Database, the organization that is providing the IANA
- #    Considerations defined in this RFC, under the memorandum of
- #    understanding with the IETF, currently ICANN, may act in accordance
- #    with all competent court orders.  No ownership claims will be made
- #    by ICANN or the IETF Trust on the database or the code.  Any person
- #    making a contribution to the database or code waives all rights to
- #    future claims in that contribution or in the TZ Database.

- *   The explicit call to the CStr() constructor creates a temporary object.
- *   Operator () on the temporary object returns a (const char *) pointer.

- * transforming Unicode strings into byte sequences.
- *
- * A .dict file begins with a standard ICU data file header
- * (DataHeader, see ucmndata.h and unicode/udata.h).
- * The UDataInfo.dataVersion field is currently unused (set to 0.0.0.0).
- *
- * After the header, the file contains the following parts.
- * Constants are defined in the DictionaryData class.
- *
- * For the data structure of BytesTrie & UCharsTrie see
- * http://site.icu-project.org/design/struct/tries
- * and the bytestrie.h and ucharstrie.h header files.
- *
- * int32_t indexes[indexesLength]; -- indexesLength=indexes[IX_STRING_TRIE_OFFSET]/4;
- *
- *      The first four indexes are byte offsets in ascending order.
- *      Each byte offset marks the start of the next part in the data file,
- *      and the end of the previous one.
- *      When two consecutive byte offsets are the same, then the corresponding part is empty.
- *      Byte offsets are offsets from after the header,
- *      that is, from the beginning of the indexes[].
- *      Each part starts at an offset with proper alignment for its data.
- *      If necessary, the previous part may include padding bytes to achieve this alignment.
- *
- *      trieType=indexes[IX_TRIE_TYPE] defines the trie type.
- *      transform=indexes[IX_TRANSFORM] defines the Unicode-to-bytes transformation.
- *          If the transformation type is TRANSFORM_TYPE_OFFSET,
- *          then the lower 21 bits contain the offset code point.
- *          Each code point c is mapped to byte b = (c - offset).
- *          Code points outside the range offset..(offset+0xff) cannot be mapped
- *          and do not occur in the dictionary.
- *
- * stringTrie; -- a serialized BytesTrie or UCharsTrie
- *
- *      The dictionary maps strings to specific values (TRIE_HAS_VALUES bit set in trieType),
- *      or it maps all strings to 0 (TRIE_HAS_VALUES bit not set).

- * Lookup a resource bundle table item with fallback on the table level.

- * and performs a lookup of both, falling back until a bundle contains a table

- * Note: Only the opening of entire bundles falls back through the default locale

-  * Mutex is a helper class for convenient locking and unlocking of a UMutex.
-  *
-  * Creating a local scope Mutex will lock a UMutex, holding the lock until the Mutex
-  * goes out of scope.
-  *
-  *  If no UMutex is specified, the ICU global mutex is implied.
-  *
-  *  For example:
-  *
-  *  static UMutex myMutex;
-  *
-  *  void Function(int arg1, int arg2)
-  *  {
-  *     static Object* foo;      // Shared read-write object
-  *     Mutex mutex(&myMutex);   // or no args for the global lock
-  *     foo->Method();
-  *     // When 'mutex' goes out of scope and gets destroyed here, the lock is released
-  *  }
-  *
-  *  Note:  Do NOT use the form 'Mutex mutex();' as that merely forward-declares a function
-  *         returning a Mutex. This is a common mistake which silently slips through the
-  *         compiler!!

-/**
- * Format of Normalizer2 .nrm data files.
- * Format version 4.0.
- *
- * Normalizer2 .nrm data files provide data for the Unicode Normalization algorithms.
- * ICU ships with data files for standard Unicode Normalization Forms
- * NFC and NFD (nfc.nrm), NFKC and NFKD (nfkc.nrm) and NFKC_Casefold (nfkc_cf.nrm).
- * Custom (application-specific) data can be built into additional .nrm files
- * with the gennorm2 build tool.
- * ICU ships with one such file, uts46.nrm, for the implementation of UTS #46.
- *
- * Normalizer2.getInstance() causes a .nrm file to be loaded, unless it has been
- * cached already. Internally, Normalizer2Impl.load() reads the .nrm file.
- *
- * A .nrm file begins with a standard ICU data file header
- * (DataHeader, see ucmndata.h and unicode/udata.h).
- * The UDataInfo.dataVersion field usually contains the Unicode version
- * for which the data was generated.
- *
- * After the header, the file contains the following parts.
- * Constants are defined as enum values of the Normalizer2Impl class.
- *
- * Many details of the data structures are described in the design doc
- * which is at http://site.icu-project.org/design/normalization/custom
- *
- * int32_t indexes[indexesLength]; -- indexesLength=indexes[IX_NORM_TRIE_OFFSET]/4;
- *
- *      The first eight indexes are byte offsets in ascending order.
- *      Each byte offset marks the start of the next part in the data file,
- *      and the end of the previous one.
- *      When two consecutive byte offsets are the same, then the corresponding part is empty.
- *      Byte offsets are offsets from after the header,
- *      that is, from the beginning of the indexes[].
- *      Each part starts at an offset with proper alignment for its data.
- *      If necessary, the previous part may include padding bytes to achieve this alignment.
- *
- *      minDecompNoCP=indexes[IX_MIN_DECOMP_NO_CP] is the lowest code point
- *      with a decomposition mapping, that is, with NF*D_QC=No.
- *      minCompNoMaybeCP=indexes[IX_MIN_COMP_NO_MAYBE_CP] is the lowest code point
- *      with NF*C_QC=No (has a one-way mapping) or Maybe (combines backward).
- *      minLcccCP=indexes[IX_MIN_LCCC_CP] (index 18, new in formatVersion 3)
- *      is the lowest code point with lccc!=0.
- *
- *      The next eight indexes are thresholds of 16-bit trie values for ranges of
- *      values indicating multiple normalization properties.
- *      They are listed here in threshold order, not in the order they are stored in the indexes.
- *          minYesNo=indexes[IX_MIN_YES_NO];
- *          minYesNoMappingsOnly=indexes[IX_MIN_YES_NO_MAPPINGS_ONLY];
- *          minNoNo=indexes[IX_MIN_NO_NO];
- *          minNoNoCompBoundaryBefore=indexes[IX_MIN_NO_NO_COMP_BOUNDARY_BEFORE];
- *          minNoNoCompNoMaybeCC=indexes[IX_MIN_NO_NO_COMP_NO_MAYBE_CC];
- *          minNoNoEmpty=indexes[IX_MIN_NO_NO_EMPTY];
- *          limitNoNo=indexes[IX_LIMIT_NO_NO];
- *          minMaybeYes=indexes[IX_MIN_MAYBE_YES];
- *      See the normTrie description below and the design doc for details.
- *
- * UCPTrie normTrie; -- see ucptrie_impl.h and ucptrie.h, same as Java CodePointTrie
- *
- *      The trie holds the main normalization data. Each code point is mapped to a 16-bit value.
- *      Rather than using independent bits in the value (which would require more than 16 bits),
- *      information is extracted primarily via range checks.
- *      Except, format version 3 uses bit 0 for hasCompBoundaryAfter().
- *      For example, a 16-bit value norm16 in the range minYesNo<=norm16<minNoNo
- *      means that the character has NF*C_QC=Yes and NF*D_QC=No properties,
- *      which means it has a two-way (round-trip) decomposition mapping.
- *      Values in the range 2<=norm16<limitNoNo are also directly indexes into the extraData
- *      pointing to mappings, compositions lists, or both.
- *      Value norm16==INERT (0 in versions 1 & 2, 1 in version 3)
- *      means that the character is normalization-inert, that is,
- *      it does not have a mapping, does not participate in composition, has a zero
- *      canonical combining class, and forms a boundary where text before it and after it
- *      can be normalized independently.
- *      For details about how multiple properties are encoded in 16-bit values
- *      see the design doc.
- *      Note that the encoding cannot express all combinations of the properties involved;
- *      it only supports those combinations that are allowed by
- *      the Unicode Normalization algorithms. Details are in the design doc as well.
- *      The gennorm2 tool only builds .nrm files for data that conforms to the limitations.
- *
- *      The trie has a value for each lead surrogate code unit representing the "worst case"
- *      properties of the 1024 supplementary characters whose UTF-16 form starts with
- *      the lead surrogate. If all of the 1024 supplementary characters are normalization-inert,
- *      then their lead surrogate code unit has the trie value INERT.
- *      When the lead surrogate unit's value exceeds the quick check minimum during processing,
- *      the properties for the full supplementary code point need to be looked up.
- *
- * uint16_t maybeYesCompositions[MIN_NORMAL_MAYBE_YES-minMaybeYes];
- * uint16_t extraData[];
- *
- *      There is only one byte offset for the end of these two arrays.
- *      The split between them is given by the constant and variable mentioned above.
- *      In version 3, the difference must be shifted right by OFFSET_SHIFT.
- *
- *      The maybeYesCompositions array contains compositions lists for characters that
- *      combine both forward (as starters in composition pairs)
- *      and backward (as trailing characters in composition pairs).
- *      Such characters do not occur in Unicode 5.2 but are allowed by
- *      the Unicode Normalization algorithms.
- *      If there are no such characters, then minMaybeYes==MIN_NORMAL_MAYBE_YES
- *      and the maybeYesCompositions array is empty.
- *      If there are such characters, then minMaybeYes is subtracted from their norm16 values
- *      to get the index into this array.
- *
- *      The extraData array contains compositions lists for "YesYes" characters,
- *      followed by mappings and optional compositions lists for "YesNo" characters,
- *      followed by only mappings for "NoNo" characters.
- *      (Referring to pairs of NFC/NFD quick check values.)
- *      The norm16 values of those characters are directly indexes into the extraData array.
- *      In version 3, the norm16 values must be shifted right by OFFSET_SHIFT
- *      for accessing extraData.
- *
- *      The data structures for compositions lists and mappings are described in the design doc.
- *
- * uint8_t smallFCD[0x100]; -- new in format version 2
- *
- *      This is a bit set to help speed up FCD value lookups in the absence of a full
- *      UTrie2 or other large data structure with the full FCD value mapping.
- *
- *      Each smallFCD bit is set if any of the corresponding 32 BMP code points
- *      has a non-zero FCD value (lccc!=0 or tccc!=0).
- *      Bit 0 of smallFCD[0] is for U+0000..U+001F. Bit 7 of smallFCD[0xff] is for U+FFE0..U+FFFF.
- *      A bit for 32 lead surrogates is set if any of the 32k corresponding
- *      _supplementary_ code points has a non-zero FCD value.
- *
- *      This bit set is most useful for the large blocks of CJK characters with FCD=0.
- *
- * Changes from format version 1 to format version 2 ---------------------------
- *
- * - Addition of data for raw (not recursively decomposed) mappings.
- *   + The MAPPING_NO_COMP_BOUNDARY_AFTER bit in the extraData is now also set when
- *     the mapping is to an empty string or when the character combines-forward.
- *     This subsumes the one actual use of the MAPPING_PLUS_COMPOSITION_LIST bit which
- *     is then repurposed for the MAPPING_HAS_RAW_MAPPING bit.
- *   + For details see the design doc.
- * - Addition of indexes[IX_MIN_YES_NO_MAPPINGS_ONLY] and separation of the yesNo extraData into
- *   distinct ranges (combines-forward vs. not)
- *   so that a range check can be used to find out if there is a compositions list.
- *   This is fully equivalent with formatVersion 1's MAPPING_PLUS_COMPOSITION_LIST flag.
- *   It is needed for the new (in ICU 49) composePair(), not for other normalization.
- * - Addition of the smallFCD[] bit set.
- *
- * Changes from format version 2 to format version 3 (ICU 60) ------------------
- *
- * - norm16 bit 0 indicates hasCompBoundaryAfter(),
- *   except that for contiguous composition (FCC) the tccc must be checked as well.
- *   Data indexes and ccc values are shifted left by one (OFFSET_SHIFT).
- *   Thresholds like minNoNo are tested before shifting.
- *
- * - Algorithmic mapping deltas are shifted left by two more bits (total DELTA_SHIFT),
- *   to make room for two bits (three values) indicating whether the tccc is 0, 1, or greater.
- *   See DELTA_TCCC_MASK etc.
- *   This helps with fetching tccc/FCD values and FCC hasCompBoundaryAfter().
- *   minMaybeYes is 8-aligned so that the DELTA_TCCC_MASK bits can be tested directly.
- *
- * - Algorithmic mappings are only used for mapping to "comp yes and ccc=0" characters,
- *   and ASCII characters are mapped algorithmically only to other ASCII characters.
- *   This helps with hasCompBoundaryBefore() and compose() fast paths.
- *   It is never necessary any more to loop for algorithmic mappings.
- *
- * - Addition of indexes[IX_MIN_NO_NO_COMP_BOUNDARY_BEFORE],
- *   indexes[IX_MIN_NO_NO_COMP_NO_MAYBE_CC], and indexes[IX_MIN_NO_NO_EMPTY],
- *   and separation of the noNo extraData into distinct ranges.
- *   With this, the noNo norm16 value indicates whether the mapping is
- *   compose-normalized, not normalized but hasCompBoundaryBefore(),
- *   not even that, or maps to an empty string.
- *   hasCompBoundaryBefore() can be determined solely from the norm16 value.
- *
- * - The norm16 value for Hangul LVT is now different from that for Hangul LV,
- *   so that hasCompBoundaryAfter() need not check for the syllable type.
- *   For Hangul LV, minYesNo continues to be used (no comp-boundary-after).
- *   For Hangul LVT, minYesNoMappingsOnly|HAS_COMP_BOUNDARY_AFTER is used.
- *   The extraData units at these indexes are set to firstUnit=2 and firstUnit=3, respectively,
- *   to simplify some code.
- *
- * - The extraData firstUnit bit 5 is no longer necessary
- *   (norm16 bit 0 used instead of firstUnit MAPPING_NO_COMP_BOUNDARY_AFTER),
- *   is reserved again, and always set to 0.
- *
- * - Addition of indexes[IX_MIN_LCCC_CP], the first code point where lccc!=0.
- *   This used to be hardcoded to U+0300, but in data like NFKC_Casefold it is lower:
- *   U+00AD Soft Hyphen maps to an empty string,
- *   which is artificially assigned "worst case" values lccc=1 and tccc=255.
- *
- * - A mapping to an empty string has explicit lccc=1 and tccc=255 values.
- *
- * Changes from format version 3 to format version 4 (ICU 63) ------------------
- *
- * Switched from UTrie2 to UCPTrie/CodePointTrie.
- *
- * The new trie no longer stores different values for surrogate code *units* vs.
- * surrogate code *points*.
- * Lead surrogates still have values for optimized UTF-16 string processing.
- * When looking up code point properties, the code now checks for lead surrogates and
- * treats them as inert.
- *
- * gennorm2 now has to reject mappings for surrogate code points.
- * UTS #46 maps unpaired surrogates to U+FFFD in code rather than via its
- * custom normalization data file.

- *      total number of bytes in the file. (Not counting the standard headers.)
- *
- *      The sixth index (indexes[PropNameData::IX_MAX_NAME_LENGTH]) has the
- *      maximum length of any Unicode property (or property value) alias.
- *      (Without normalization, that is, including underscores etc.)
- *
- * int32_t valueMaps[];
- *
- *      The valueMaps[] begins with a map from UProperty enums to properties,
- *      followed by the per-property value maps from property values to names,
- *      for those properties that have named values.
- *      (Binary & enumerated, plus General_Category_Mask.)
- *
- *      valueMaps[0] contains the number of UProperty enum ranges.
- *      For each range:
- *        int32_t start, limit -- first and last+1 UProperty enum of a dense range
- *        Followed by (limit-start) pairs of
- *          int32_t nameGroupOffset;
- *            Offset into nameGroups[] for the property's names/aliases.
- *          int32_t valueMapIndex;
- *            Offset of the property's value map in the valueMaps[] array.
- *            If the valueMapIndex is 0, then the property does not have named values.
- *
- *      For each property's value map:
- *      int32_t bytesTrieOffset; -- Offset into bytesTries[] for name->value mapping.
- *      int32_t numRanges;
- *        If numRanges is in the range 1..15, then that many ranges of values follow.
- *        Per range:
- *          int32_t start, limit -- first and last+1 UProperty enum of a range
- *          Followed by (limit-start) entries of
- *            int32_t nameGroupOffset;
- *              Offset into nameGroups[] for the property value's names/aliases.
- *              If the nameGroupOffset is 0, then this is not a named value for this property.
- *              (That is, the ranges need not be dense.)
- *        If numRanges is >=0x10, then (numRanges-0x10) sorted values
- *        and then (numRanges-0x10) corresponding nameGroupOffsets follow.
- *        Values are sorted as signed integers.
- *        In this case, the set of values is dense; no nameGroupOffset will be 0.
- *
- *      For both properties and property values, ranges are sorted by their start/limit values.
- *
- * uint8_t bytesTries[];
- *
- *      This is a sequence of BytesTrie structures, byte-serialized tries for
- *      mapping from names/aliases to values.
- *      The first one maps from property names/aliases to UProperty enum constants.
- *      The following ones are indexed by property value map bytesTrieOffsets
- *      for mapping each property's names/aliases to their property values.
- *
- * char nameGroups[];
- *
- *      This is a sequence of property name groups.
- *      Each group is a list of names/aliases (invariant-character strings) for
- *      one property or property value, in the order of UCharNameChoice.
- *      The first byte of each group is the number of names in the group.
- *      It is followed by that many NUL-terminated strings.
- *      The first string is for the short name; if there is no short name,
- *      then the first string is empty.
- *      The second string is the long name. Further strings are additional aliases.
- *
- *      The first name group is for a property rather than a property value,
- *      so that a nameGroupOffset of 0 can be used to indicate "no value"
- *      in a property's sparse value ranges.

- * \def U_SIGNED_RIGHT_SHIFT_IS_ARITHMETIC
- * Nearly all CPUs and compilers implement a right-shift of a signed integer
- * as an Arithmetic Shift Right which copies the sign bit (the Most Significant Bit (MSB))
- * into the vacated bits (sign extension).
- * For example, (int32_t)0xfff5fff3>>4 becomes 0xffff5fff and -1>>1=-1.
- *
- * This can be useful for storing a signed value in the upper bits
- * and another bit field in the lower bits.
- * The signed value can be retrieved by simple right-shifting.
- *
- * This is consistent with the Java language.
- *
- * However, the C standard allows compilers to implement a right-shift of a signed integer
- * as a Logical Shift Right which copies a 0 into the vacated bits.
- * For example, (int32_t)0xfff5fff3>>4 becomes 0x0fff5fff and -1>>1=0x7fffffff.
- *
- * Code that depends on the natural behavior should be guarded with this macro,
- * with an alternate path for unusual platforms.

-//  RBBISetBuilder   Handles processing of Unicode Sets from RBBI rules

-//      Starting with the rules parse tree from the scanner,
-//
-//                   -  Enumerate the set of UnicodeSets that are referenced
-//                      by the RBBI rules.
-//                   -  compute a set of non-overlapping character ranges
-//                      with all characters within a range belonging to the same
-//                      set of input uniocde sets.
-//                   -  Derive a set of non-overlapping UnicodeSet (like things)
-//                      that will correspond to columns in the state table for
-//                      the RBBI execution engine.  All characters within one
-//                      of these sets belong to the same set of the original
-//                      UnicodeSets from the user's rules.
-//                   -  construct the trie table that maps input characters
-//                      to the index of the matching non-overlapping set of set from
-//                      the previous step.

-    // whether a pair is safe, run it through the main forward state table, starting
-    // from each state. If the the final state is the same, no matter what the starting state,
-    // the pair is safe.
-    //
-    // 2. Build a state table that recognizes the safe pairs. It's similar to their
-    // forward table, with a column for each input character [class], and a row for
-    // each state. Row 1 is the start state, and row 0 is the stop state. Initially
-    // create an additional state for each input character category; being in
-    // one of these states means that the character has been seen, and is potentially
-    // the first of a pair. In each of these rows, the entry for the second character

-    // All other table entries are set to the state corresponding the current input
-    // character, allowing that charcter to be the of a start following pair.

-    // the first and second pair categories are swapped when building the table.

- * Implementation Notes
- *
- * Resource bundles are read in once, and thereafter cached.
- * ResourceBundle statically keeps track of which files have been
- * read, so we are guaranteed that each file is read at most once.
- * Resource bundles can be loaded from different data directories and
- * will be treated as distinct, even if they are for the same locale.
- *
- * Resource bundles are lightweight objects, which have pointers to
- * one or more shared Hashtable objects containing all the data.
- * Copying would be cheap, but there is no copy constructor, since
- * there wasn't one in the original API.
- *
- * The ResourceBundle parsing mechanism is implemented as a transition
- * network, for easy maintenance and modification.  The network is
- * implemented as a matrix (instead of in code) to make this even
- * easier.  The matrix contains Transition objects.  Each Transition
- * object describes a destination node and an action to take before
- * moving to the destination node.  The source node is encoded by the
- * index of the object in the array that contains it.  The pieces
- * needed to understand the transition network are the enums for node
- * IDs and actions, the parse() method, which walks through the
- * network and implements the actions, and the network itself.  The
- * network guarantees certain conditions, for example, that a new
- * resource will not be closed until one has been opened first; or
- * that data will not be stored into a TaggedList until a TaggedList
- * has been created.  Nonetheless, the code in parse() does some
- * consistency checks as it runs the network, and fails with an
- * U_INTERNAL_PROGRAM_ERROR if one of these checks fails.  If the input
- * data has a bad format, an U_INVALID_FORMAT_ERROR is returned.  If you
- * see an U_INTERNAL_PROGRAM_ERROR the transition matrix has a bug in
- * it.
- *
- * Old functionality of multiple locales in a single file is still
- * supported.  For this reason, LOCALE names override FILE names.  If
- * data for en_US is located in the en.txt file, once it is loaded,
- * the code will not care where it came from (other than remembering
- * which directory it came from).  However, if there is an en_US
- * resource in en_US.txt, that will take precedence.  There is no
- * limit to the number or type of resources that can be stored in a
- * file, however, files are only searched in a specific way.  If
- * en_US_CA is requested, then first en_US_CA.txt is searched, then
- * en_US.txt, then en.txt, then default.txt.  So it only makes sense
- * to put certain locales in certain files.  In this example, it would
- * be logical to put en_US_CA, en_US, and en into the en.txt file,
- * since they would be found there if asked for.  The extreme example
- * is to place all locale resources into default.txt, which should
- * also work.
- *
- * Inheritance is implemented.  For example, xx_YY_zz inherits as
- * follows: xx_YY_zz, xx_YY, xx, default.  Inheritance is implemented
- * as an array of hashtables.  There will be from 1 to 4 hashtables in
- * the array.
- *
- * Fallback files are implemented.  The fallback pattern is Language
- * Country Variant (LCV) -> LC -> L.  Fallback is first done for the
- * requested locale.  Then it is done for the default locale, as
- * returned by Locale::getDefault().  Then the special file
- * default.txt is searched for the default locale.  The overall FILE
- * fallback path is LCV -> LC -> L -> dLCV -> dLC -> dL -> default.
- *
- * Note that although file name searching includes the default locale,
- * once a ResourceBundle object is constructed, the inheritance path
- * no longer includes the default locale.  The path is LCV -> LC -> L
- * -> default.
- *
- * File parsing is lazy.  Nothing is parsed unless it is called for by
- * someone.  So when a ResourceBundle for xx_YY_zz is constructed,
- * only that locale is parsed (along with anything else in the same
- * file).  Later, if the FooBar tag is asked for, and if it isn't
- * found in xx_YY_zz, then xx_YY.txt will be parsed and checked, and
- * so forth, until the chain is exhausted or the tag is found.
- *
- * Thread-safety is implemented around caches, both the cache that
- * stores all the resouce data, and the cache that stores flags
- * indicating whether or not a file has been visited.  These caches
- * delete their storage at static cleanup time, when the process
- * quits.
- *
- * ResourceBundle supports TableCollation as a special case.  This
- * involves having special ResourceBundle objects which DO own their
- * data, since we don't want large collation rule strings in the
- * ResourceBundle cache (these are already cached in the
- * TableCollation cache).  TableCollation files (.ctx files) have the
- * same format as normal resource data files, with a different
- * interpretation, from the standpoint of ResourceBundle.  .ctx files
- * are loaded into otherwise ordinary ResourceBundle objects.  They
- * don't inherit (that's implemented by TableCollation) and they own
- * their data (as mentioned above).  However, they still support
- * possible multiple locales in a single .ctx file.  (This is in
- * practice a bad idea, since you only want the one locale you're
- * looking for, and only one tag will be present
- * ("CollationElements"), so you don't need an inheritance chain of
- * multiple locales.)  Up to 4 locale resources will be loaded from a
- * .ctx file; everything after the first 4 is ignored (parsed and
- * deleted).  (Normal .txt files have no limit.)  Instead of being
- * loaded into the cache, and then looked up as needed, the locale
- * resources are read straight into the ResourceBundle object.
- *
- * The Index, which used to reside in default.txt, has been moved to a
- * new file, index.txt.  This file contains a slightly modified format
- * with the addition of the "InstalledLocales" tag; it looks like:
- *
- * Index {
- *   InstalledLocales {
- *     ar
- *     ..
- *     zh_TW
- *   }
- * }

- * ICUService
- */
-
- /**
- * <p>A Service provides access to service objects that implement a
- * particular service, e.g. transliterators.  Users provide a String
- * id (for example, a locale string) to the service, and get back an
- * object for that id.  Service objects can be any kind of object.  A
- * new service object is returned for each query. The caller is
- * responsible for deleting it.</p>
- *
- * <p>Services 'canonicalize' the query ID and use the canonical ID to
- * query for the service.  The service also defines a mechanism to
- * 'fallback' the ID multiple times.  Clients can optionally request
- * the actual ID that was matched by a query when they use an ID to
- * retrieve a service object.</p>
- *
- * <p>Service objects are instantiated by ICUServiceFactory objects
- * registered with the service.  The service queries each
- * ICUServiceFactory in turn, from most recently registered to
- * earliest registered, until one returns a service object.  If none
- * responds with a service object, a fallback ID is generated, and the
- * process repeats until a service object is returned or until the ID
- * has no further fallbacks.</p>
- *
- * <p>In ICU 2.4, UObject (the base class of service instances) does
- * not define a polymorphic clone function.  ICUService uses clones to
- * manage ownership.  Thus, for now, ICUService defines an abstract
- * method, cloneInstance, that clients must implement to create clones
- * of the service instances.  This may change in future releases of
- * ICU.</p>
- *
- * <p>ICUServiceFactories can be dynamically registered and
- * unregistered with the service.  When registered, an
- * ICUServiceFactory is installed at the head of the factory list, and
- * so gets 'first crack' at any keys or fallback keys.  When
- * unregistered, it is removed from the service and can no longer be
- * located through it.  Service objects generated by this factory and
- * held by the client are unaffected.</p>
- *
- * <p>If a service has variants (e.g., the different variants of
- * BreakIterator) an ICUServiceFactory can use the prefix of the
- * ICUServiceKey to determine the variant of a service to generate.
- * If it does not support all variants, it can request
- * previously-registered factories to handle the ones it does not
- * support.</p>
- *
- * <p>ICUService uses ICUServiceKeys to query factories and perform
- * fallback.  The ICUServiceKey defines the canonical form of the ID,
- * and implements the fallback strategy.  Custom ICUServiceKeys can be
- * defined that parse complex IDs into components that
- * ICUServiceFactories can more easily use.  The ICUServiceKey can
- * cache the results of this parsing to save repeated effort.
- * ICUService provides convenience APIs that take UnicodeStrings and
- * generate default ICUServiceKeys for use in querying.</p>
- *
- * <p>ICUService provides API to get the list of IDs publicly
- * supported by the service (although queries aren't restricted to
- * this list).  This list contains only 'simple' IDs, and not fully
- * unique IDs.  ICUServiceFactories are associated with each simple ID
- * and the responsible factory can also return a human-readable
- * localized version of the simple ID, for use in user interfaces.
- * ICUService can also provide an array of the all the localized
- * visible IDs and their corresponding internal IDs.</p>
- *
- * <p>ICUService implements ICUNotifier, so that clients can register
- * to receive notification when factories are added or removed from
- * the service.  ICUService provides a default EventListener
- * subinterface, ServiceListener, which can be registered with the
- * service.  When the service changes, the ServiceListener's
- * serviceChanged method is called with the service as the
- * argument.</p>
- *
- * <p>The ICUService API is both rich and generic, and it is expected
- * that most implementations will statically 'wrap' ICUService to
- * present a more appropriate API-- for example, to declare the type
- * of the objects returned from get, to limit the factories that can
- * be registered with the service, or to define their own listener
- * interface with a custom callback method.  They might also customize
- * ICUService by overriding it, for example, to customize the
- * ICUServiceKey and fallback strategy.  ICULocaleService is a
- * subclass of ICUService that uses Locale names as IDs and uses
- * ICUServiceKeys that implement the standard resource bundle fallback
- * strategy.  Most clients will wish to subclass it instead of
- * ICUService.</p>

-/*
- * General implementation notes:
- *
- * Throughout the implementation, there are comments like (W2) that refer to
- * rules of the BiDi algorithm, in this example to the second rule of the
- * resolution of weak types.
- *
- * For handling surrogate pairs, where two UChar's form one "abstract" (or UTF-32)
- * character according to UTF-16, the second UChar gets the directional property of
- * the entire character assigned, while the first one gets a BN, a boundary
- * neutral, type, which is ignored by most of the algorithm according to
- * rule (X9) and the implementation suggestions of the BiDi algorithm.
- *
- * Later, adjustWSLevels() will set the level for each BN to that of the
- * following character (UChar), which results in surrogate pairs getting the
- * same level on each of their surrogates.
- *
- * In a UTF-8 implementation, the same thing could be done: the last byte of
- * a multi-byte sequence would get the "real" property, while all previous
- * bytes of that sequence would get BN.
- *
- * It is not possible to assign all those parts of a character the same real
- * property because this would fail in the resolution of weak types with rules
- * that look at immediately surrounding types.
- *
- * As a related topic, this implementation does not remove Boundary Neutral
- * types from the input, but ignores them wherever this is relevant.
- * For example, the loop for the resolution of the weak types reads
- * types until it finds a non-BN.
- * Also, explicit embedding codes are neither changed into BN nor removed.
- * They are only treated the same way real BNs are.
- * As stated before, adjustWSLevels() takes care of them at the end.
- * For the purpose of conformance, the levels of all these codes
- * do not matter.
- *
- * Note that this implementation modifies the dirProps
- * after the initial setup, when applying X5c (replace FSI by LRI or RLI),
- * X6, N0 (replace paired brackets by L or R).
- *
- * In this implementation, the resolution of weak types (W1 to W6),
- * neutrals (N1 and N2), and the assignment of the resolved level (In)
- * are all done in one single loop, in resolveImplicitLevels().
- * Changes of dirProp values are done on the fly, without writing
- * them back to the dirProps array.
- *
- *
- * This implementation contains code that allows to bypass steps of the
- * algorithm that are not needed on the specific paragraph
- * in order to speed up the most common cases considerably,
- * like text that is entirely LTR, or RTL text without numbers.
- *
- * Most of this is done by setting a bit for each directional property
- * in a flags variable and later checking for whether there are
- * any LTR characters or any RTL characters, or both, whether
- * there are any explicit embedding codes, etc.
- *
- * If the (Xn) steps are performed, then the flags are re-evaluated,
- * because they will then not contain the embedding codes any more
- * and will be adjusted for override codes, so that subsequently
- * more bypassing may be possible than what the initial flags suggested.
- *
- * If the text is not mixed-directional, then the
- * algorithm steps for the weak type resolution are not performed,
- * and all levels are set to the paragraph level.
- *
- * If there are no explicit embedding codes, then the (Xn) steps
- * are not performed.
- *
- * If embedding levels are supplied as a parameter, then all
- * explicit embedding codes are ignored, and the (Xn) steps
- * are not performed.
- *
- * White Space types could get the level of the run they belong to,
- * and are checked with a test of (flags&MASK_EMBEDDING) to
- * consider if the paragraph direction should be considered in
- * the flags variable.
- *
- * If there are no White Space types in the paragraph, then
- * (L1) is not necessary in adjustWSLevels().

- * Resolve the explicit levels as specified by explicit embedding codes.

- * after taking the explicit embeddings into account.
- *
- * The BiDi algorithm is designed to result in the same behavior whether embedding
- * levels are externally specified (from "styled text", supposedly the preferred
- * method) or set by explicit embedding codes (LRx, RLx, PDF, FSI, PDI) in the plain text.
- * That is why (X9) instructs to remove all not-isolate explicit codes (and BN).
- * However, in a real implementation, the removal of these codes and their index
- * positions in the plain text is undesirable since it would result in
- * reallocated, reindexed text.
- * Instead, this implementation leaves the codes in there and just ignores them
- * in the subsequent processing.
- * In order to get the same reordering behavior, positions with a BN or a not-isolate
- * explicit embedding code just get the same level assigned as the last "real"
- * character.
- *
- * Some implementations, not this one, then overwrite some of these
- * directionality properties at "real" same-level-run boundaries by
- * L or R codes so that the resolution of weak types can be performed on the
- * entire paragraph at once instead of having to parse it once more and
- * perform that resolution on same-level-runs.
- * This limits the scope of the implicit rules in effectively
- * the same way as the run limits.
- *
- * Instead, this implementation does not modify these codes, except for
- * paired brackets whose properties (ON) may be replaced by L or R.
- * On one hand, the paragraph has to be scanned for same-level-runs, but
- * on the other hand, this saves another loop to reset these codes,
- * or saves making and modifying a copy of dirProps[].
- *
- *
- * Note that (Pn) and (Xn) changed significantly from version 4 of the BiDi algorithm.
- *
- *
- * Handling the stack of explicit levels (Xn):
- *
- * With the BiDi stack of explicit levels, as pushed with each
- * LRE, RLE, LRO, RLO, LRI, RLI and FSI and popped with each PDF and PDI,
- * the explicit level must never exceed UBIDI_MAX_EXPLICIT_LEVEL.
- *
- * In order to have a correct push-pop semantics even in the case of overflows,
- * overflow counters and a valid isolate counter are used as described in UAX#9
- * section 3.3.2 "Explicit Levels and Directions".
- *
- * This implementation assumes that UBIDI_MAX_EXPLICIT_LEVEL is odd.
- *
- * Returns normally the direction; -1 if there was a memory shortage

-      PROPERTIES  STATE  TABLE
-
- In table impTabProps,
-      - the ON column regroups ON and WS, FSI, RLI, LRI and PDI
-      - the BN column regroups BN, LRE, RLE, LRO, RLO, PDF
-      - the Res column is the reduced property assigned to a run
-
- Action 1: process current run1, init new run1
-        2: init new run2
-        3: process run1, process run2, init new run1
-        4: process run1, set run1=run2, init new run2
-
- Notes:
-  1) This table is used in resolveImplicitLevels().
-  2) This table triggers actions when there is a change in the Bidi
-     property of incoming characters (action 1).
-  3) Most such property sequences are processed immediately (in
-     fact, passed to processPropertySeq().
-  4) However, numbers are assembled as one sequence. This means
-     that undefined situations (like CS following digits, until
-     it is known if the next char will be a digit) are held until
-     following chars define them.
-     Example: digits followed by CS, then comes another CS or ON;
-              the digits will be processed, then the CS assigned
-              as the start of an ON sequence (action 3).
-  5) There are cases where more than one sequence must be
-     processed, for instance digits followed by CS followed by L:
-     the digits must be processed as one sequence, and the CS
-     must be processed as an ON sequence, all this before starting
-     assembling chars for the opening L sequence.

-      LEVELS  STATE  TABLES
-
- In all levels state tables,
-      - state 0 is the initial state
-      - the Res column is the increment to add to the text level
-        for this property sequence.
-
- The impAct arrays for each table of a pair map the local action
- numbers of the table to the total list of actions. For instance,
- action 2 in a given table corresponds to the action number which
- appears in entry [2] of the impAct array for that table.
- The first entry of all impAct arrays must be 0.
-
- Action 1: init conditional sequence
-        2: prepend conditional sequence to current sequence
-        3: set ON sequence to new level - 1
-        4: init EN/AN/ON sequence
-        5: fix EN/AN/ON sequence followed by R
-        6: set previous level sequence to level 2
-
- Notes:
-  1) These tables are used in processPropertySeq(). The input
-     is property sequences as determined by resolveImplicitLevels.
-  2) Most such property sequences are processed immediately
-     (levels are assigned).
-  3) However, some sequences cannot be assigned a final level till
-     one or more following sequences are received. For instance,
-     ON following an R sequence within an even-level paragraph.
-     If the following sequence is R, the ON sequence will be
-     assigned basic run level+1, and so will the R sequence.
-  4) S is generally handled like ON, since its level will be fixed
-     to paragraph level in adjustWSLevels().

- * General remarks about the functions in this file:
- *
- * These functions deal with the aspects of potentially mixed-directional
- * text in a single paragraph or in a line of a single paragraph
- * which has already been processed according to
- * the Unicode 6.3 BiDi algorithm as defined in
- * http://www.unicode.org/unicode/reports/tr9/ , version 28,
- * also described in The Unicode Standard, Version 6.3.0 .
- *
- * This means that there is a UBiDi object with a levels
- * and a dirProps array.
- * paraLevel and direction are also set.
- * Only if the length of the text is zero, then levels==dirProps==NULL.
- *
- * The overall directionality of the paragraph
- * or line is used to bypass the reordering steps if possible.
- * Even purely RTL text does not need reordering there because
- * the ubidi_getLogical/VisualIndex() functions can compute the
- * index on the fly in such a case.
- *
- * The implementation of the access to same-level-runs and of the reordering
- * do attempt to provide better performance and less memory usage compared to
- * a direct implementation of especially rule (L2) with an array of
- * one (32-bit) integer per text character.
- *
- * Here, the levels array is scanned as soon as necessary, and a vector of
- * same-level-runs is created. Reordering then is done on this vector.
- * For each run of text positions that were resolved to the same level,
- * only 8 bytes are stored: the first text position of the run and the visual
- * position behind the run after reordering.
- * One sign bit is used to hold the directionality of the run.
- * This is inefficient if there are many very short runs. If the average run
- * length is <2, then this uses more memory.
- *
- * In a further attempt to save memory, the levels array is never changed
- * after all the resolution rules (Xn, Wn, Nn, In).
- * Many functions have to consider the field trailingWSStart:
- * if it is less than length, then there is an implicit trailing run
- * at the paraLevel,
- * which is not reflected in the levels array.
- * This allows a line UBiDi object to use the same levels array as
- * its paragraph parent object.
- *
- * When a UBiDi object is created for a line of a paragraph, then the
- * paragraph's levels and dirProps arrays are reused by way of setting
- * a pointer into them, not by copying. This again saves memory and forbids to
- * change the now shared levels for (L1).
- */
-
-/* handle trailing WS (L1) -------------------------------------------------- */
-
-/*
- * setTrailingWSStart() sets the start index for a trailing
- * run of WS in the line. This is necessary because we do not modify
- * the paragraph's levels array that we just point into.
- * Using trailingWSStart is another form of performing (L1).
- *
- * To make subsequent operations easier, we also include the run
- * before the WS if it is at the paraLevel - we merge the two here.
- *
- * This function is called only from ubidi_setLine(), so pBiDi->paraLevel is
- * set correctly for the line even when contextual multiple paragraphs.

-/*
- * These internal functions form the core of string case mappings.
- * They map single code points to result code points or strings and take
- * all necessary conditions (context, locale ID, options) into account.
- *
- * They do not iterate over the source or write to the destination
- * so that the same functions are useful for non-standard string storage,
- * such as in a Replaceable (for Transliterator) or UTF-8/32 strings etc.
- * For the same reason, the "surrounding text" context is passed in as a
- * UCaseContextIterator which does not make any assumptions about
- * the underlying storage.
- *
- * This section contains helper functions that check for conditions
- * in the input text surrounding the current code point
- * according to SpecialCasing.txt.
- *
- * Each helper function gets the index
- * - after the current code point if it looks at following text
- * - before the current code point if it looks at preceding text
- *
- * Unicode 3.2 UAX 21 "Case Mappings" defines the conditions as follows:
- *
- * Final_Sigma
- *   C is preceded by a sequence consisting of
- *     a cased letter and a case-ignorable sequence,
- *   and C is not followed by a sequence consisting of
- *     an ignorable sequence and then a cased letter.
- *
- * More_Above
- *   C is followed by one or more characters of combining class 230 (ABOVE)
- *   in the combining character sequence.
- *
- * After_Soft_Dotted
- *   The last preceding character with combining class of zero before C
- *   was Soft_Dotted,
- *   and there is no intervening combining character class 230 (ABOVE).
- *
- * Before_Dot
- *   C is followed by combining dot above (U+0307).
- *   Any sequence of characters with a combining class that is neither 0 nor 230
- *   may intervene between the current character and the combining dot above.
- *
- * The erratum from 2002-10-31 adds the condition
- *
- * After_I
- *   The last preceding base character was an uppercase I, and there is no
- *   intervening combining character class 230 (ABOVE).
- *
- *   (See Jitterbug 2344 and the comments on After_I below.)
- *
- * Helper definitions in Unicode 3.2 UAX 21:
- *
- * D1. A character C is defined to be cased
- *     if it meets any of the following criteria:
- *
- *   - The general category of C is Titlecase Letter (Lt)
- *   - In [CoreProps], C has one of the properties Uppercase, or Lowercase
- *   - Given D = NFD(C), then it is not the case that:
- *     D = UCD_lower(D) = UCD_upper(D) = UCD_title(D)
- *     (This third criterium does not add any characters to the list
- *      for Unicode 3.2. Ignored.)
- *
- * D2. A character C is defined to be case-ignorable
- *     if it meets either of the following criteria:
- *
- *   - The general category of C is
- *     Nonspacing Mark (Mn), or Enclosing Mark (Me), or Format Control (Cf), or
- *     Letter Modifier (Lm), or Symbol Modifier (Sk)
- *   - C is one of the following characters 
- *     U+0027 APOSTROPHE
- *     U+00AD SOFT HYPHEN (SHY)
- *     U+2019 RIGHT SINGLE QUOTATION MARK
- *            (the preferred character for apostrophe)
- *
- * D3. A case-ignorable sequence is a sequence of
- *     zero or more case-ignorable characters.

- * See Jitterbug 2344:
- * The condition After_I for Turkic-lowercasing of U+0307 combining dot above
- * is checked in ICU 2.0, 2.1, 2.6 but was not in 2.2 & 2.4 because
- * we made those releases compatible with Unicode 3.2 which had not fixed
- * a related bug in SpecialCasing.txt.
- *
- * From the Jitterbug 2344 text:
- * ... this bug is listed as a Unicode erratum
- * from 2002-10-31 at http://www.unicode.org/uni2errata/UnicodeErrata.html
- * <quote>
- * There are two errors in SpecialCasing.txt.
- * 1. Missing semicolons on two lines. ... [irrelevant for ICU]
- * 2. An incorrect context definition. Correct as follows:
- * < 0307; ; 0307; 0307; tr After_Soft_Dotted; # COMBINING DOT ABOVE
- * < 0307; ; 0307; 0307; az After_Soft_Dotted; # COMBINING DOT ABOVE
- * ---
- * > 0307; ; 0307; 0307; tr After_I; # COMBINING DOT ABOVE
- * > 0307; ; 0307; 0307; az After_I; # COMBINING DOT ABOVE
- * where the context After_I is defined as:
- * The last preceding base character was an uppercase I, and there is no
- * intervening combining character class 230 (ABOVE).
- * </quote>
- *
- * Note that SpecialCasing.txt even in Unicode 3.2 described the condition as:
- *
- * # When lowercasing, remove dot_above in the sequence I + dot_above, which will turn into i.
- * # This matches the behavior of the canonically equivalent I-dot_above
- *
- * See also the description in this place in older versions of uchar.c (revision 1.100).

-/*
- * Case folding is similar to lowercasing.
- * The result may be a simple mapping, i.e., a single code point, or
- * a full mapping, i.e., a string.
- * If the case folding for a code point is the same as its simple (1:1) lowercase mapping,
- * then only the lowercase mapping is stored.
- *
- * Some special cases are hardcoded because their conditions cannot be
- * parsed and processed from CaseFolding.txt.
- *
- * Unicode 3.2 CaseFolding.txt specifies for its status field:
-
-# C: common case folding, common mappings shared by both simple and full mappings.
-# F: full case folding, mappings that cause strings to grow in length. Multiple characters are separated by spaces.
-# S: simple case folding, mappings to single characters where different from F.
-# T: special case for uppercase I and dotted uppercase I
-#    - For non-Turkic languages, this mapping is normally not used.
-#    - For Turkic languages (tr, az), this mapping can be used instead of the normal mapping for these characters.
-#
-# Usage:
-#  A. To do a simple case folding, use the mappings with status C + S.
-#  B. To do a full case folding, use the mappings with status C + F.
-#
-#    The mappings with status T can be used or omitted depending on the desired case-folding
-#    behavior. (The default option is to exclude them.)
-
- * Unicode 3.2 has 'T' mappings as follows:
-
-0049; T; 0131; # LATIN CAPITAL LETTER I
-0130; T; 0069; # LATIN CAPITAL LETTER I WITH DOT ABOVE
-
- * while the default mappings for these code points are:
-
-0049; C; 0069; # LATIN CAPITAL LETTER I
-0130; F; 0069 0307; # LATIN CAPITAL LETTER I WITH DOT ABOVE
-
- * U+0130 has no simple case folding (simple-case-folds to itself).

-/** These are the functions used to register a library's memory cleanup
- * functions.  Each library should define a single library register function
- * to call this API.  In the i18n library, it is ucln_i18n_registerCleanup().
- *
- * None of the cleanup functions should use a mutex to clean up an API's
- * allocated memory because a cleanup function is not meant to be thread safe,
- * and plenty of data cannot be reference counted in order to make sure that
- * no one else needs the allocated data.
- *
- * In order to make a cleanup function get called when u_cleanup is called,
- * You should add your function to the library specific cleanup function.
- * If the cleanup function is not in the common library, the code that
- * allocates the memory should call the library specific cleanup function.
- * For instance, in the i18n library, any memory allocated statically must
- * call ucln_i18n_registerCleanup() from the ucln_in.h header.  These library
- * cleanup functions are needed in order to prevent a circular dependency
- * between the common library and any other library.
- *
- * The order of the cleanup is very important.  In general, an API that
- * depends on a second API should be cleaned up before the second API.
- * For instance, the default converter in ustring depends upon the converter
- * API.  So the default converter should be closed before the converter API
- * has its cache flushed.  This will prevent any memory leaks due to
- * reference counting.
- *
- * Please see common/ucln_cmn.{h,c} and i18n/ucln_in.{h,c} for examples.

- * Implementation note for m:n conversions

- * While collecting source units to find the longest match for m:n conversion,

- * When a second buffer does not yield a match on all of the previously stored
- * source units, then they must be "replayed", i.e., fed back into the converter.

- * The code relies on the fact that replaying will not nest -
- * converting a replay buffer will not result in a replay.
- * This is because a replay is necessary only after the _continuation_ of a
- * partial match failed, but a replay buffer is converted as a whole.
- * It may result in some of its units being stored again for a partial match,
- * but there will not be a continuation _during_ the replay which could fail.
- *
- * It is conceivable that a callback function could call the converter
- * recursively in a way that causes another replay to be stored, but that
- * would be an error in the callback function.
- * Such violations will cause assertion failures in a debug build,
- * and wrong output, but they will not cause a crash.

-/*
- * I am disabling the generic ISO-2022 converter after proposing to do so on
- * the icu mailing list two days ago.
- *
- * Reasons:
- * 1. It does not fully support the ISO-2022/ECMA-35 specification with all of
- *    its designation sequences, single shifts with return to the previous state,
- *    switch-with-no-return to UTF-16BE or similar, etc.
- *    This is unlike the language-specific variants like ISO-2022-JP which
- *    require a much smaller repertoire of ISO-2022 features.
- *    These variants continue to be supported.
- * 2. I believe that no one is really using the generic ISO-2022 converter
- *    but rather always one of the language-specific variants.
- *    Note that ICU's generic ISO-2022 converter has always output one escape
- *    sequence followed by UTF-8 for the whole stream.
- * 3. Switching between subcharsets is extremely slow, because each time
- *    the previous converter is closed and a new one opened,
- *    without any kind of caching, least-recently-used list, etc.
- * 4. The code is currently buggy, and given the above it does not seem
- *    reasonable to spend the time on maintenance.
- * 5. ISO-2022 subcharsets should normally be used with 7-bit byte encodings.
- *    This means, for example, that when ISO-8859-7 is designated, the following
- *    ISO-2022 bytes 00..7f should be interpreted as ISO-8859-7 bytes 80..ff.
- *    The ICU ISO-2022 converter does not handle this - and has no information
- *    about which subconverter would have to be shifted vs. which is designed
- *    for 7-bit ISO-2022.

-* The converter iterates over each Unicode codepoint

-* (iii) If the first character on the line is represented by two bytes then a two
-*       byte character escape sequence should precede it
-* (iv)  If no escape sequence is encountered then the characters are ASCII
-* (v)   Latin(ISO-8859-1) and Greek(ISO-8859-7) characters must be designated to G2,
-*       and invoked with SS2 (ESC N).
-* (vi)  If there is any G0 designation in text, there must be a switch to
-*       ASCII or to JIS X 0201-Roman before a space character (but not
-*       necessarily before "ESC 4/14 2/0" or "ESC N ' '") or control

-* Rules for ISO-2022-CN Encoding:
-* i)   The designator sequence must appear once on a line before any instance

-* ii)  If two lines contain characters from the same character set, both lines
-*      must include the designator sequence.
-* iii) Once the designator sequence is known, a shifting sequence has to be found
-*      to invoke the  shifting
-* iv)  All lines start in ASCII and end in ASCII.
-* v)   Four shifting sequences are employed for this purpose:

- * See icuhtml/design/conversion/conversion_extensions.html
- *
- * Conversion extensions serve three purposes:
- * 1. They support m:n mappings.
- * 2. They support extension-only conversion files that are used together
- *    with the regular conversion data in base files.
- * 3. They support mappings with more complicated meta data,
- *    for example "good one-way" mappings (|4).
- *
- * A base file may contain an extension table (explicitly requested or
- * implicitly generated for m:n mappings), but its extension table is not
- * used when an extension-only file is used.
- *
- * It is an error if a base file contains any regular (not extension) mapping
- * from the same sequence as a mapping in the extension file
- * because the base mapping would hide the extension mapping.
- *
- *
- * Data for conversion extensions:
- *
- * One set of data structures per conversion direction (to/from Unicode).
- * The data structures are sorted by input units to allow for binary search.
- * Input sequences of more than one unit are handled like contraction tables
- * in collation:
- * The lookup value of a unit points to another table that is to be searched
- * for the next unit, recursively.
- *
- * For conversion from Unicode, the initial code point is looked up in
- * a 3-stage trie for speed,
- * with an additional table of unique results to save space.
- *
- * Long output strings are stored in separate arrays, with length and index
- * in the lookup tables.
- * Output results also include a flag distinguishing roundtrip from
- * (reverse) fallback mappings.
- *
- * Input Unicode strings must not begin or end with unpaired surrogates
- * to avoid problems with matches on parts of surrogate pairs.
- *
- * Mappings from multiple characters (code points or codepage state
- * table sequences) must be searched preferring the longest match.
- * For this to work and be efficient, the variable-width table must contain
- * all mappings that contain prefixes of the multiple characters.
- * If an extension table is built on top of a base table in another file
- * and a base table entry is a prefix of a multi-character mapping, then
- * this is an error.
- *
- *
- * Implementation note:
- *
- * Currently, the parser and several checks in the code limit the number
- * of UChars or bytes in a mapping to
- * UCNV_EXT_MAX_UCHARS and UCNV_EXT_MAX_BYTES, respectively,
- * which are output value limits in the data structure.
- *
- * For input, this is not strictly necessary - it is a hard limit only for the
- * buffers in UConverter that are used to store partial matches.
- *
- * Input sequences could otherwise be arbitrarily long if partial matches
- * need not be stored (i.e., if a sequence does not span several buffers with too
- * many units before the last buffer), although then results would differ
- * depending on whether partial matches exceed the limits or not,
- * which depends on the pattern of buffer sizes.
- *
- *
- * Data structure:
- *
- * int32_t indexes[>=32];
- *
- *   Array of indexes and lengths etc. The length of the array is at least 32.
- *   The actual length is stored in indexes[0] to be forward compatible.
- *
- *   Each index to another array is the number of bytes from indexes[].
- *   Each length of an array is the number of array base units in that array.
- *
- *   Some of the structures may not be present, in which case their indexes
- *   and lengths are 0.
- *
- *   Usage of indexes[i]:
- *   [0]  length of indexes[]
- *
- *   // to Unicode table
- *   [1]  index of toUTable[] (array of uint32_t)
- *   [2]  length of toUTable[]
- *   [3]  index of toUUChars[] (array of UChar)
- *   [4]  length of toUUChars[]
- *
- *   // from Unicode table, not for the initial code point
- *   [5]  index of fromUTableUChars[] (array of UChar)
- *   [6]  index of fromUTableValues[] (array of uint32_t)
- *   [7]  length of fromUTableUChars[] and fromUTableValues[]
- *   [8]  index of fromUBytes[] (array of char)
- *   [9]  length of fromUBytes[]
- *
- *   // from Unicode trie for initial-code point lookup
- *   [10] index of fromUStage12[] (combined array of uint16_t for stages 1 & 2)
- *   [11] length of stage 1 portion of fromUStage12[]
- *   [12] length of fromUStage12[]
- *   [13] index of fromUStage3[] (array of uint16_t indexes into fromUStage3b[])
- *   [14] length of fromUStage3[]
- *   [15] index of fromUStage3b[] (array of uint32_t like fromUTableValues[])
- *   [16] length of fromUStage3b[]
- *
- *   [17] Bit field containing numbers of bytes:
- *        31..24 reserved, 0
- *        23..16 maximum input bytes
- *        15.. 8 maximum output bytes
- *         7.. 0 maximum bytes per UChar
- *
- *   [18] Bit field containing numbers of UChars:
- *        31..24 reserved, 0
- *        23..16 maximum input UChars
- *        15.. 8 maximum output UChars
- *         7.. 0 maximum UChars per byte
- *
- *   [19] Bit field containing flags:
- *               (extension table unicodeMask)
- *         1     UCNV_HAS_SURROGATES flag for the extension table
- *         0     UCNV_HAS_SUPPLEMENTARY flag for the extension table
- *
- *   [20]..[30] reserved, 0
- *   [31] number of bytes for the entire extension structure
- *   [>31] reserved; there are indexes[0] indexes
- *
- *
- * uint32_t toUTable[];
- *
- *   Array of byte/value pairs for lookups for toUnicode conversion.
- *   The array is partitioned into sections like collation contraction tables.
- *   Each section contains one word with the number of following words and
- *   a default value for when the lookup in this section yields no match.
- *
- *   A section is sorted in ascending order of input bytes,
- *   allowing for fast linear or binary searches.
- *   The builder may store entries for a contiguous range of byte values
- *   (compare difference between the first and last one with count),
- *   which then allows for direct array access.
- *   The builder should always do this for the initial table section.
- *
- *   Entries may have 0 values, see below.
- *   No two entries in a section have the same byte values.
- *
- *   Each uint32_t contains an input byte value in bits 31..24 and the
- *   corresponding lookup value in bits 23..0.
- *   Interpret the value as follows:
- *     if(value==0) {
- *       no match, see below
- *     } else if(value<0x1f0000) {
- *       partial match - use value as index to the next toUTable section
- *       and match the next unit; (value indexes toUTable[value])
- *     } else {
- *       if(bit 23 set) {
- *         roundtrip;
- *       } else {
- *         fallback;
- *       }
- *       unset value bit 23;
- *       if(value<=0x2fffff) {
- *         (value-0x1f0000) is a code point; (BMP: value<=0x1fffff)
- *       } else {
- *         bits 17..0 (value&0x3ffff) is an index to
- *           the result UChars in toUUChars[]; (0 indexes toUUChars[0])
- *         length of the result=((value>>18)-12); (length=0..19)
- *       }
- *     }
- *
- *   The first word in a section contains the number of following words in the
- *   input byte position (bits 31..24, number=1..0xff).
- *   The value of the initial word is used when the current byte is not found
- *   in this section.
- *   If the value is not 0, then it represents a result as above.
- *   If the value is 0, then the search has to return a shorter match with an
- *   earlier default value as the result, or result in "unmappable" even for the
- *   initial bytes.
- *   If the value is 0 for the initial toUTable entry, then the initial byte
- *   does not start any mapping input.
- *
- *
- * UChar toUUChars[];
- *
- *   Contains toUnicode mapping results, stored as sequences of UChars.
- *   Indexes and lengths stored in the toUTable[].
- *
- *
- * UChar fromUTableUChars[];
- * uint32_t fromUTableValues[];
- *
- *   The fromUTable is split into two arrays, but works otherwise much like
- *   the toUTable. The array is partitioned into sections like collation
- *   contraction tables and toUTable.
- *   A row in the table consists of same-index entries in fromUTableUChars[]
- *   and fromUTableValues[].
- *
- *   Interpret a value as follows:
- *     if(value==0) {
- *       no match, see below
- *     } else if(value<=0xffffff) { (bits 31..24 are 0)
- *       partial match - use value as index to the next fromUTable section
- *       and match the next unit; (value indexes fromUTable[value])
- *     } else {
- *       if(value==0x80000001) {
- *         return no mapping, but request for <subchar1>;
- *       }
- *       if(bit 31 set) {
- *         roundtrip (|0);
- *       } else if(bit 30 set) {
- *         "good one-way" mapping (|4); -- new in ICU4C 51, _MBCSHeader.version 5.4/4.4
- *       } else {
- *         normal fallback (|1);
- *       }
- *       // bit 29 reserved, 0
- *       length=(value>>24)&0x1f; (bits 28..24)
- *       if(length==1..3) {
- *         bits 23..0 contain 1..3 bytes, padded with 00s on the left;
- *       } else {
- *         bits 23..0 (value&0xffffff) is an index to
- *           the result bytes in fromUBytes[]; (0 indexes fromUBytes[0])
- *       }
- *     }
- *       
- *   The first pair in a section contains the number of following pairs in the
- *   UChar position (16 bits, number=1..0xffff).
- *   The value of the initial pair is used when the current UChar is not found
- *   in this section.
- *   If the value is not 0, then it represents a result as above.
- *   If the value is 0, then the search has to return a shorter match with an
- *   earlier default value as the result, or result in "unmappable" even for the
- *   initial UChars.
- *
- *   If the from Unicode trie is present, then the from Unicode search tables
- *   are not used for initial code points.
- *   In this case, the first entries (index 0) in the tables are not used
- *   (reserved, set to 0) because a value of 0 is used in trie results
- *   to indicate no mapping.
- *
- *
- * uint16_t fromUStage12[];
- *
- *   Stages 1 & 2 of a trie that maps an initial code point.
- *   Indexes in stage 1 are all offset by the length of stage 1 so that the
- *   same array pointer can be used for both stages.
- *   If (c>>10)>=(length of stage 1) then c does not start any mapping.
- *   Same bit distribution as for regular conversion tries.
- *
- *
- * uint16_t fromUStage3[];
- * uint32_t fromUStage3b[];
- *
- *   Stage 3 of the trie. The first array simply contains indexes to the second,
- *   which contains words in the same format as fromUTableValues[].
- *   Use a stage 3 granularity of 4, which allows for 256k stage 3 entries,
- *   and 16-bit entries in stage 3 allow for 64k stage 3b entries.
- *   The stage 3 granularity means that the stage 2 entry needs to be left-shifted.
- *
- *   Two arrays are used because it is expected that more than half of the stage 3
- *   entries will be zero. The 16-bit index stage 3 array saves space even
- *   considering storing a total of 6 bytes per non-zero entry in both arrays
- *   together.
- *   Using a stage 3 granularity of >1 diminishes the compactability in that stage
- *   but provides a larger effective addressing space in stage 2.
- *   All but the final result stage use 16-bit entries to save space.
- *
- *   fromUStage3b[] contains a zero for "no mapping" at its index 0,
- *   and may contain UCNV_EXT_FROM_U_SUBCHAR1 at index 1 for "<subchar1> SUB mapping"
- *   (i.e., "no mapping" with preference for <subchar1> rather than <subchar>),
- *   and all other items are unique non-zero results.
- *
- *   The default value of a fromUTableValues[] section that is referenced
- *   _directly_ from a fromUStage3b[] item may also be UCNV_EXT_FROM_U_SUBCHAR1,
- *   but this value must not occur anywhere else in fromUTableValues[]
- *   because "no mapping" is always a property of a single code point,
- *   never of multiple.
- *
- *
- * char fromUBytes[];
- *
- *   Contains fromUnicode mapping results, stored as sequences of chars.
- *   Indexes and lengths stored in the fromUTableValues[].

-/* Format of cnvalias.icu -----------------------------------------------------
- *
- * cnvalias.icu is a binary, memory-mappable form of convrtrs.txt.
- * This binary form contains several tables. All indexes are to uint16_t
- * units, and not to the bytes (uint8_t units). Addressing everything on
- * 16-bit boundaries allows us to store more information with small index
- * numbers, which are also 16-bit in size. The majority of the table (except
- * the string table) are 16-bit numbers.
- *
- * First there is the size of the Table of Contents (TOC). The TOC
- * entries contain the size of each section. In order to find the offset
- * you just need to sum up the previous offsets.
- * The TOC length and entries are an array of uint32_t values.
- * The first section after the TOC starts immediately after the TOC.
- *
- * 1) This section contains a list of converters. This list contains indexes
- * into the string table for the converter name. The index of this list is
- * also used by other sections, which are mentioned later on.
- * This list is not sorted.
- *
- * 2) This section contains a list of tags. This list contains indexes
- * into the string table for the tag name. The index of this list is
- * also used by other sections, which are mentioned later on.
- * This list is in priority order of standards.
- *
- * 3) This section contains a list of sorted unique aliases. This
- * list contains indexes into the string table for the alias name. The
- * index of this list is also used by other sections, like the 4th section.
- * The index for the 3rd and 4th section is used to get the
- * alias -> converter name mapping. Section 3 and 4 form a two column table.
- * Some of the most significant bits of each index may contain other
- * information (see findConverter for details).
- *
- * 4) This section contains a list of mapped converter names. Consider this
- * as a table that maps the 3rd section to the 1st section. This list contains
- * indexes into the 1st section. The index of this list is the same index in
- * the 3rd section. There is also some extra information in the high bits of
- * each converter index in this table. Currently it's only used to say that
- * an alias mapped to this converter is ambiguous. See UCNV_CONVERTER_INDEX_MASK
- * and UCNV_AMBIGUOUS_ALIAS_MAP_BIT for more information. This section is
- * the predigested form of the 5th section so that an alias lookup can be fast.
- *
- * 5) This section contains a 2D array with indexes to the 6th section. This
- * section is the full form of all alias mappings. The column index is the
- * index into the converter list (column header). The row index is the index
- * to tag list (row header). This 2D array is the top part a 3D array. The
- * third dimension is in the 6th section.
- *
- * 6) This is blob of variable length arrays. Each array starts with a size,
- * and is followed by indexes to alias names in the string table. This is
- * the third dimension to the section 5. No other section should be referencing
- * this section.
- *
- * 7) Starting in ICU 3.6, this can be a UConverterAliasOptions struct. Its
- * presence indicates that a section 9 exists. UConverterAliasOptions specifies
- * what type of string normalization is used among other potential things in the
- * future.
- *
- * 8) This is the string table. All strings are indexed on an even address.
- * There are two reasons for this. First many chip architectures locate strings
- * faster on even address boundaries. Second, since all indexes are 16-bit
- * numbers, this string table can be 128KB in size instead of 64KB when we
- * only have strings starting on an even address.
- *
- * 9) When present this is a set of prenormalized strings from section 8. This
- * table contains normalized strings with the dashes and spaces stripped out,
- * and all strings lowercased. In the future, the options in section 7 may state
- * other types of normalization.
- *
- * Here is the concept of section 5 and 6. It's a 3D cube. Each tag
- * has a unique alias among all converters. That same alias can
- * be mentioned in other standards on different converters,
- * but only one alias per tag can be unique.
- *
- *

- *

-  LMBCS
-
-  (Lotus Multi-Byte Character Set)
-
-  LMBCS was invented in the late 1980's and is primarily used in Lotus Notes 
-  databases and in Lotus 1-2-3 files. Programmers who work with the APIs 
-  into these products will sometimes need to deal with strings in this format.
-
-  The code in this file provides an implementation for an ICU converter of 
-  LMBCS to and from Unicode. 
-
-  Since the LMBCS character set is only sparsely documented in existing 
-  printed or online material, we have added  extensive annotation to this 
-  file to serve as a guide to understanding LMBCS. 
-
-  LMBCS was originally designed with these four sometimes-competing design goals:
-
-  -Provide encodings for the characters in 12 existing national standards
-   (plus a few other characters)
-  -Minimal memory footprint
-  -Maximal speed of conversion into the existing national character sets
-  -No need to track a changing state as you interpret a string.
-
-
-  All of the national character sets LMBCS was trying to encode are 'ANSI'
-  based, in that the bytes from 0x20 - 0x7F are almost exactly the 
-  same common Latin unaccented characters and symbols in all character sets. 
-
-  So, in order to help meet the speed & memory design goals, the common ANSI 
-  bytes from 0x20-0x7F are represented by the same single-byte values in LMBCS. 
-
-  The general LMBCS code unit is from 1-3 bytes. We can describe the 3 bytes as
-  follows:
-
-  [G] D1 [D2]
-
-  That is, a sometimes-optional 'group' byte, followed by 1 and sometimes 2
-  data bytes. The maximum size of a LMBCS chjaracter is 3 bytes:
-*/
-#define ULMBCS_CHARSIZE_MAX      3
-/*
-  The single-byte values from 0x20 to 0x7F are examples of single D1 bytes.
-  We often have to figure out if byte values are below or above this, so we 
-  use the ANSI nomenclature 'C0' and 'C1' to refer to the range of control 
-  characters just above & below the common lower-ANSI  range */
-#define ULMBCS_C0END           0x1F   
-#define ULMBCS_C1START         0x80   
-/*
-  Since LMBCS is always dealing in byte units. we create a local type here for 
-  dealing with these units of LMBCS code units:
-
-*/  
-typedef uint8_t ulmbcs_byte_t;
-
-/* 
-   Most of the values less than 0x20 are reserved in LMBCS to announce 
-   which national  character standard is being used for the 'D' bytes. 
-   In the comments we show the common name and the IBM character-set ID
-   for these character-set announcers:

-   So, the beginning of understanding LMBCS is that IF the first byte of a LMBCS 
-   character is one of those 12 values, you can interpret the remaining bytes of 
-   that character as coming from one of those character sets. Since the lower 
-   ANSI bytes already are represented in single bytes, using one of the character 
-   set announcers is used to announce a character that starts with a byte of 
-   0x80 or greater.
-
-   The character sets are  arranged so that the single byte sets all appear 
-   before the multi-byte character sets. When we need to tell whether a 
-   group byte is for a single byte char set or not we use this define: */

-However, to fully understand LMBCS, you must also understand a series of 
-exceptions & optimizations made in service of the design goals. 
-
-First, those of you who are character set mavens may have noticed that
-the 'double-byte' character sets are actually multi-byte character sets 
-that can have 1 or two bytes, even in the upper-ascii range. To force
-each group byte to introduce a fixed-width encoding (to make it faster to 
-count characters), we use a convention of doubling up on the group byte 
-to introduce any single-byte character > 0x80 in an otherwise double-byte
-character set. So, for example, the LMBCS sequence x10 x10 xAE is the 
-same as '0xAE' in the Japanese code page 943.
-
-Next, you will notice that the list of group bytes has some gaps. 
-These are used in various ways.
-
-We reserve a few special single byte values for common control 
-characters. These are in the same place as their ANSI eqivalents for speed.

-
-/*
- * UTF-7 is a stateful encoding of Unicode.
- * It is defined in RFC 2152. (http://www.ietf.org/rfc/rfc2152.txt)
- * It was intended for use in Internet email systems, using in its bytewise
- * encoding only a subset of 7-bit US-ASCII.
- * UTF-7 is deprecated in favor of UTF-8/16/32 and SCSU, but still
- * occasionally used.
- *
- * For converting Unicode to UTF-7, the RFC allows to encode some US-ASCII
- * characters directly or in base64. Especially, the characters in set O
- * as defined in the RFC (see below) may be encoded directly but are not
- * allowed in, e.g., email headers.
- * By default, the ICU UTF-7 converter encodes set O directly.
- * By choosing the option "version=1", set O will be escaped instead.
- * For example:
- *     utf7Converter=ucnv_open("UTF-7,version=1");
- *
- * For details about email headers see RFC 2047.
- */
-
-/*
- * Tests for US-ASCII characters belonging to character classes
- * defined in UTF-7.
- *
- * Set D (directly encoded characters) consists of the following
- * characters: the upper and lower case letters A through Z
- * and a through z, the 10 digits 0-9, and the following nine special
- * characters (note that "+" and "=" are omitted):
- *     '(),-./:?
- *
- * Set O (optional direct characters) consists of the following
- * characters (note that "\" and "~" are omitted):
- *     !"#$%&*;<=>@[]^_`{|}
- *
- * According to the rules in RFC 2152, the byte values for the following
- * US-ASCII characters are not used in UTF-7 and are therefore illegal:
- * - all C0 control codes except for CR LF TAB
- * - BACKSLASH
- * - TILDE
- * - DEL
- * - all codes beyond US-ASCII, i.e. all >127

- * RFC 2060: INTERNET MESSAGE ACCESS PROTOCOL - VERSION 4rev1
- * http://www.ietf.org/rfc/rfc2060.txt
- *
- * 5.1.3.  Mailbox International Naming Convention
- *
- * By convention, international mailbox names are specified using a
- * modified version of the UTF-7 encoding described in [UTF-7].  The
- * purpose of these modifications is to correct the following problems
- * with UTF-7:
- *
- *    1) UTF-7 uses the "+" character for shifting; this conflicts with
- *       the common use of "+" in mailbox names, in particular USENET
- *       newsgroup names.
- *
- *    2) UTF-7's encoding is BASE64 which uses the "/" character; this
- *       conflicts with the use of "/" as a popular hierarchy delimiter.
- *
- *    3) UTF-7 prohibits the unencoded usage of "\"; this conflicts with
- *       the use of "\" as a popular hierarchy delimiter.
- *
- *    4) UTF-7 prohibits the unencoded usage of "~"; this conflicts with
- *       the use of "~" in some servers as a home directory indicator.
- *
- *    5) UTF-7 permits multiple alternate forms to represent the same
- *       string; in particular, printable US-ASCII chararacters can be
- *       represented in encoded form.
- *
- * In modified UTF-7, printable US-ASCII characters except for "&"
- * represent themselves; that is, characters with octet values 0x20-0x25
- * and 0x27-0x7e.  The character "&" (0x26) is represented by the two-
- * octet sequence "&-".
- *
- * All other characters (octet values 0x00-0x1f, 0x7f-0xff, and all
- * Unicode 16-bit octets) are represented in modified BASE64, with a
- * further modification from [UTF-7] that "," is used instead of "/".
- * Modified BASE64 MUST NOT be used to represent any printing US-ASCII
- * character which can represent itself.
- *
- * "&" is used to shift to modified BASE64 and "-" to shift back to US-
- * ASCII.  All names start in US-ASCII, and MUST end in US-ASCII (that
- * is, a name that ends with a Unicode 16-bit octet MUST end with a "-
- * ").
- *
- * For example, here is a mailbox name which mixes English, Japanese,
- * and Chinese text: ~peter/mail/&ZeVnLIqe-/&U,BTFw-
- */
-
-/*
- * Tests for US-ASCII characters belonging to character classes
- * defined in UTF-7.
- *
- * Set D (directly encoded characters) consists of the following
- * characters: the upper and lower case letters A through Z
- * and a through z, the 10 digits 0-9, and the following nine special
- * characters (note that "+" and "=" are omitted):
- *     '(),-./:?
- *
- * Set O (optional direct characters) consists of the following
- * characters (note that "\" and "~" are omitted):
- *     !"#$%&*;<=>@[]^_`{|}
- *
- * According to the rules in RFC 2152, the byte values for the following
- * US-ASCII characters are not used in UTF-7 and are therefore illegal:
- * - all C0 control codes except for CR LF TAB
- * - BACKSLASH
- * - TILDE
- * - DEL
- * - all codes beyond US-ASCII, i.e. all >127

-/**************************************HZ Encoding*************************************************
-* Rules for HZ encoding
-* 
-*   In ASCII mode, a byte is interpreted as an ASCII character, unless a
-*   '~' is encountered. The character '~' is an escape character. By
-*   convention, it must be immediately followed ONLY by '~', '{' or '\n'
-*   (<LF>), with the following special meaning.
-
-*   1. The escape sequence '~~' is interpreted as a '~'.
-*   2. The escape-to-GB sequence '~{' switches the mode from ASCII to GB.
-*   3. The escape sequence '~\n' is a line-continuation marker to be
-*     consumed with no output produced.
-*   In GB mode, characters are interpreted two bytes at a time as (pure)
-*   GB codes until the escape-from-GB code '~}' is read. This code
-*   switches the mode from GB back to ASCII.  (Note that the escape-
-*   from-GB code '~}' ($7E7D) is outside the defined GB range.)
-*
-*   Source: RFC 1842
-*
-*   Note that the formal syntax in RFC 1842 is invalid. I assume that the
-*   intended definition of single-byte-segment is as follows (pedberg):
-*   single-byte-segment = single-byte-seq 1*single-byte-char

- *       b) if preceeded by specific consonants and the ligatures have pre-composed

-*   encoding:   UTF-8

-*
-*   created on: 2000jul03
-*   created by: Markus W. Scherer
-*
-*   The current code in this file replaces the previous implementation
-*   of conversion code from multi-byte codepages to Unicode and back.
-*   This implementation supports the following:
-*   - legacy variable-length codepages with up to 4 bytes per character
-*   - all Unicode code points (up to 0x10ffff)
-*   - efficient distinction of unassigned vs. illegal byte sequences
-*   - it is possible in fromUnicode() to directly deal with simple
-*     stateful encodings (used for EBCDIC_STATEFUL)
-*   - it is possible to convert Unicode code points
-*     to a single zero byte (but not as a fallback except for SBCS)
-*
-*   Remaining limitations in fromUnicode:
-*   - byte sequences must not have leading zero bytes
-*   - except for SBCS codepages: no fallback mapping from Unicode to a zero byte
-*   - limitation to up to 4 bytes per character
-*
-*   ICU 2.8 (late 2003) adds a secondary data structure which lifts some of these
-*   limitations and adds m:n character mappings and other features.
-*   See ucnv_ext.h for details.
-*
-*   Change history: 
-*
-*    5/6/2001       Ram       Moved  MBCS_SINGLE_RESULT_FROM_U,MBCS_STAGE_2_FROM_U,

- * The main difference is an additional _MBCSHeader field with
- * - the length (number of uint32_t) of the _MBCSHeader
- * - flags for further incompatible data format changes
- * - flags for further, backward compatible data format changes
- *
- * The MBCS_OPT_FROM_U flag indicates that most of the fromUnicode data is omitted from
- * the file and needs to be reconstituted at load time.
- * This requires a utf8Friendly format with an additional mbcsIndex table for fast
- * (and UTF-8-friendly) fromUnicode conversion for Unicode code points up to maxFastUChar.
- * (For details about these structures see below, and see ucnvmbcs.h.)
- *
- *   utf8Friendly also implies that the fromUnicode mappings are stored in ascending order
- *   of the Unicode code points. (This requires that the .ucm file has the |0 etc.
- *   precision markers for all mappings.)
- *
- *   All fallbacks have been moved to the extension table, leaving only roundtrips in the
- *   omitted data that can be reconstituted from the toUnicode data.
- *
- *   Of the stage 2 table, the part corresponding to maxFastUChar and below is omitted.
- *   With only roundtrip mappings in the base fromUnicode data, this part is fully
- *   redundant with the mbcsIndex and will be reconstituted from that (also using the
- *   stage 1 table which contains the information about how stage 2 was compacted).
- *
- *   The rest of the stage 2 table, the part for code points above maxFastUChar,
- *   is stored in the file and will be appended to the reconstituted part.
- *
- *   The entire fromUBytes array is omitted from the file and will be reconstitued.
- *   This is done by enumerating all toUnicode roundtrip mappings, performing
- *   each mapping (using the stage 1 and reconstituted stage 2 tables) and
- *   writing instead of reading the byte values.
- *
- * _MBCSHeader version 4.3
- *
- * Change from version 4.2:
- * - Optional utf8Friendly data structures, with 64-entry stage 3 block
- *   allocation for parts of the BMP, and an additional mbcsIndex in non-SBCS
- *   files which can be used instead of stages 1 & 2.
- *   Faster lookups for roundtrips from most commonly used characters,
- *   and lookups from UTF-8 byte sequences with a natural bit distribution.
- *   See ucnvmbcs.h for more details.
- *
- * Change from version 4.1:
- * - Added an optional extension table structure at the end of the .cnv file.
- *   It is present if the upper bits of the header flags field contains a non-zero
- *   byte offset to it.
- *   Files that contain only a conversion table and no base table
- *   use the special outputType MBCS_OUTPUT_EXT_ONLY.
- *   These contain the base table name between the MBCS header and the extension
- *   data.
- *
- * Change from version 4.0:
- * - Replace header.reserved with header.fromUBytesLength so that all
- *   fields in the data have length.
- *
- * Changes from version 3 (for performance improvements):
- * - new bit distribution for state table entries
- * - reordered action codes
- * - new data structure for single-byte fromUnicode
- *   + stage 2 only contains indexes
- *   + stage 3 stores 16 bits per character with classification bits 15..8
- * - no multiplier for stage 1 entries
- * - stage 2 for non-single-byte codepages contains the index and the flags in
- *   one 32-bit value
- * - 2-byte and 4-byte fromUnicode results are stored directly as 16/32-bit integers
- *
- * For more details about old versions of the MBCS data structure, see
- * the corresponding versions of this file.
- *
- * Converting stateless codepage data ---------------------------------------***
- * (or codepage data with simple states) to Unicode.
- *
- * Data structure and algorithm for converting from complex legacy codepages
- * to Unicode. (Designed before 2000-may-22.)
- *
- * The basic idea is that the structure of legacy codepages can be described
- * with state tables.
- * When reading a byte stream, each input byte causes a state transition.
- * Some transitions result in the output of a code point, some result in
- * "unassigned" or "illegal" output.
- * This is used here for character conversion.
- *
- * The data structure begins with a state table consisting of a row
- * per state, with 256 entries (columns) per row for each possible input
- * byte value.
- * Each entry is 32 bits wide, with two formats distinguished by
- * the sign bit (bit 31):
- *
- * One format for transitional entries (bit 31 not set) for non-final bytes, and
- * one format for final entries (bit 31 set).
- * Both formats contain the number of the next state in the same bit
- * positions.
- * State 0 is the initial state.
- *
- * Most of the time, the offset values of subsequent states are added
- * up to a scalar value. This value will eventually be the index of
- * the Unicode code point in a table that follows the state table.
- * The effect is that the code points for final state table rows
- * are contiguous. The code points of final state rows follow each other
- * in the order of the references to those final states by previous
- * states, etc.
- *
- * For some terminal states, the offset is itself the output Unicode
- * code point (16 bits for a BMP code point or 20 bits for a supplementary
- * code point (stored as code point minus 0x10000 so that 20 bits are enough).
- * For others, the code point in the Unicode table is stored with either
- * one or two code units: one for BMP code points, two for a pair of
- * surrogates.
- * All code points for a final state entry take up the same number of code
- * units, regardless of whether they all actually _use_ the same number
- * of code units. This is necessary for simple array access.
- *
- * An additional feature comes in with what in ICU is called "fallback"
- * mappings:
- *
- * In addition to round-trippable, precise, 1:1 mappings, there are often
- * mappings defined between similar, though not the same, characters.
- * Typically, such mappings occur only in fromUnicode mapping tables because
- * Unicode has a superset repertoire of most other codepages. However, it
- * is possible to provide such mappings in the toUnicode tables, too.
- * In this case, the fallback mappings are partly integrated into the
- * general state tables because the structure of the encoding includes their
- * byte sequences.
- * For final entries in an initial state, fallback mappings are stored in
- * the entry itself like with roundtrip mappings.
- * For other final entries, they are stored in the code units table if
- * the entry is for a pair of code units.
- * For single-unit results in the code units table, there is no space to
- * alternatively hold a fallback mapping; in this case, the code unit
- * is stored as U+fffe (unassigned), and the fallback mapping needs to
- * be looked up by the scalar offset value in a separate table.
- *
- * "Unassigned" state entries really mean "structurally unassigned",
- * i.e., such a byte sequence will never have a mapping result.
- *
- * The interpretation of the bits in each entry is as follows:
- *
- * Bit 31 not set, not a terminal entry ("transitional"):
- * 30..24 next state
- * 23..0  offset delta, to be added up
- *
- * Bit 31 set, terminal ("final") entry:
- * 30..24 next state (regardless of action code)
- * 23..20 action code:
- *        action codes 0 and 1 result in precise-mapping Unicode code points
- *        0  valid byte sequence
- *           19..16 not used, 0
- *           15..0  16-bit Unicode BMP code point
- *                  never U+fffe or U+ffff
- *        1  valid byte sequence
- *           19..0  20-bit Unicode supplementary code point
- *                  never U+fffe or U+ffff
- *
- *        action codes 2 and 3 result in fallback (unidirectional-mapping) Unicode code points
- *        2  valid byte sequence (fallback)
- *           19..16 not used, 0
- *           15..0  16-bit Unicode BMP code point as fallback result
- *        3  valid byte sequence (fallback)
- *           19..0  20-bit Unicode supplementary code point as fallback result
- *
- *        action codes 4 and 5 may result in roundtrip/fallback/unassigned/illegal results
- *        depending on the code units they result in
- *        4  valid byte sequence
- *           19..9  not used, 0
- *            8..0  final offset delta
- *                  pointing to one 16-bit code unit which may be
- *                  fffe  unassigned -- look for a fallback for this offset
- *                  ffff  illegal
- *        5  valid byte sequence
- *           19..9  not used, 0
- *            8..0  final offset delta
- *                  pointing to two 16-bit code units
- *                  (typically UTF-16 surrogates)
- *                  the result depends on the first code unit as follows:
- *                  0000..d7ff  roundtrip BMP code point (1st alone)
- *                  d800..dbff  roundtrip surrogate pair (1st, 2nd)
- *                  dc00..dfff  fallback surrogate pair (1st-400, 2nd)
- *                  e000        roundtrip BMP code point (2nd alone)
- *                  e001        fallback BMP code point (2nd alone)
- *                  fffe        unassigned
- *                  ffff        illegal
- *           (the final offset deltas are at most 255 * 2,
- *            times 2 because of storing code unit pairs)
- *
- *        6  unassigned byte sequence
- *           19..16 not used, 0
- *           15..0  16-bit Unicode BMP code point U+fffe (new with version 2)
- *                  this does not contain a final offset delta because the main
- *                  purpose of this action code is to save scalar offset values;
- *                  therefore, fallback values cannot be assigned to byte
- *                  sequences that result in this action code
- *        7  illegal byte sequence
- *           19..16 not used, 0
- *           15..0  16-bit Unicode BMP code point U+ffff (new with version 2)
- *        8  state change only
- *           19..0  not used, 0
- *           useful for state changes in simple stateful encodings,
- *           at Shift-In/Shift-Out codes
- *
- *
- *        9..15 reserved for future use
- *           current implementations will only perform a state change
- *           and ignore bits 19..0
- *
- * An encoding with contiguous ranges of unassigned byte sequences, like
- * Shift-JIS and especially EUC-TW, can be stored efficiently by having
- * at least two states for the trail bytes:
- * One trail byte state that results in code points, and one that only
- * has "unassigned" and "illegal" terminal states.
- *
- * Note: partly by accident, this data structure supports simple stateful
- * encodings without any additional logic.
- * Currently, only simple Shift-In/Shift-Out schemes are handled with
- * appropriate state tables (especially EBCDIC_STATEFUL!).
- *
- * MBCS version 2 added:
- * unassigned and illegal action codes have U+fffe and U+ffff
- * instead of unused bits; this is useful for _MBCS_SINGLE_SIMPLE_GET_NEXT_BMP()
- *
- * Converting from Unicode to codepage bytes --------------------------------***
- *
- * The conversion data structure for fromUnicode is designed for the known
- * structure of Unicode. It maps from 21-bit code points (0..0x10ffff) to
- * a sequence of 1..4 bytes, in addition to a flag that indicates if there is
- * a roundtrip mapping.
- *
- * The lookup is done with a 3-stage trie, using 11/6/4 bits for stage 1/2/3
- * like in the character properties table.
- * The beginning of the trie is at offsetFromUTable, the beginning of stage 3
- * with the resulting bytes is at offsetFromUBytes.
- *
- * Beginning with version 4, single-byte codepages have a significantly different
- * trie compared to other codepages.
- * In all cases, the entry in stage 1 is directly the index of the block of
- * 64 entries in stage 2.
- *
- * Single-byte lookup:
- *
- * Stage 2 only contains 16-bit indexes directly to the 16-blocks in stage 3.
- * Stage 3 contains one 16-bit word per result:
- * Bits 15..8 indicate the kind of result:
- *    f  roundtrip result
- *    c  fallback result from private-use code point
- *    8  fallback result from other code points
- *    0  unassigned
- * Bits 7..0 contain the codepage byte. A zero byte is always possible.
- *
- * In version 4.3, the runtime code can build an sbcsIndex for a utf8Friendly
- * file. For 2-byte UTF-8 byte sequences and some 3-byte sequences the lookup
- * becomes a 2-stage (single-index) trie lookup with 6 bits for stage 3.
- * ASCII code points can be looked up with a linear array access into stage 3.
- * See maxFastUChar and other details in ucnvmbcs.h.
- *
- * Multi-byte lookup:
- *
- * Stage 2 contains a 32-bit word for each 16-block in stage 3:
- * Bits 31..16 contain flags for which stage 3 entries contain roundtrip results
- *             test: MBCS_FROM_U_IS_ROUNDTRIP(stage2Entry, c)
- *             If this test is false, then a non-zero result will be interpreted as
- *             a fallback mapping.
- * Bits 15..0  contain the index to stage 3, which must be multiplied by 16*(bytes per char)
- *
- * Stage 3 contains 2, 3, or 4 bytes per result.
- * 2 or 4 bytes are stored as uint16_t/uint32_t in platform endianness,
- * while 3 bytes are stored as bytes in big-endian order.
- * Leading zero bytes are ignored, and the number of bytes is counted.
- * A zero byte mapping result is possible as a roundtrip result.
- * For some output types, the actual result is processed from this;
- * see ucnv_MBCSFromUnicodeWithOffsets().
- *
- * Note that stage 1 always contains 0x440=1088 entries (0x440==0x110000>>10),
- * or (version 3 and up) for BMP-only codepages, it contains 64 entries.
- *
- * In version 4.3, a utf8Friendly file contains an mbcsIndex table.
- * For 2-byte UTF-8 byte sequences and most 3-byte sequences the lookup
- * becomes a 2-stage (single-index) trie lookup with 6 bits for stage 3.
- * ASCII code points can be looked up with a linear array access into stage 3.
- * See maxFastUChar, mbcsIndex and other details in ucnvmbcs.h.
- *
- * In version 3, stage 2 blocks may overlap by multiples of the multiplier
- * for compaction.
- * In version 4, stage 2 blocks (and for single-byte codepages, stage 3 blocks)
- * may overlap by any number of entries.
- *
- * MBCS version 2 added:
- * the converter checks for known output types, which allows
- * adding new ones without crashing an unaware converter

- * ICU conversion (.cnv) data file structure, following the usual UDataInfo
- * header.
- *
- * Format version: 6.2
- *
- * struct UConverterStaticData -- struct containing the converter name, IBM CCSID,
- *                                min/max bytes per character, etc.
- *                                see ucnv_bld.h
- *
- * --------------------
- *
- * The static data is followed by conversionType-specific data structures.
- * At the moment, there are only variations of MBCS converters. They all have
- * the same toUnicode structures, while the fromUnicode structures for SBCS
- * differ from those for other MBCS-style converters.
- *
- * _MBCSHeader.version 5 is optional and not backward-compatible
- * (as usual for changes in the major version field).
- *
- * Versions 5.m work like versions 4.m except:
- * - The _MBCSHeader has variable length (and is always longer than in version 4).
- *   See the struct _MBCSHeader further description below.
- * - There is a set of flags which indicate further incompatible changes.
- *   (Reader code must reject the file if it does not recognize them all.)
- * - In particular, one of these flags indicates that most of the fromUnicode
- *   data is missing and must be reconstituted from the toUnicode data
- *   and from the utf8Friendly mbcsIndex at load time.
- *   (This only works with a utf8Friendly table.)
- *   In this case, makeconv may increase maxFastUChar automatically to U+FFFF.
- *
- * The first of these versions is 5.3, which is like 4.3 except for the differences above.
- *
- * When possible, makeconv continues to generate version 4.m files.
- *
- * _MBCSHeader.version 5.4/4.4 supports "good one-way" mappings (|4)
- * in the extension tables (fromUTableValues bit 30). See ucnv_ext.h for details.
- *
- * _MBCSHeader.version 4.3 optionally modifies the fromUnicode data structures
- * slightly and optionally adds a table for conversion to MBCS (non-SBCS)
- * charsets.
- *
- * The modifications are to make the data utf8Friendly. Not every 4.3 file
- * file contains utf8Friendly data.
- * It is utf8Friendly if _MBCSHeader.version[2]!=0.
- * In this case, the data structures are utf8Friendly up to the code point
- *   maxFastUChar=((_MBCSHeader.version[2]<<8)|0xff)
- *
- * A utf8Friendly file has fromUnicode stage 3 entries for code points up to
- * maxFastUChar allocated in blocks of 64 for indexing with the 6 bits from
- * a UTF-8 trail byte. ASCII is allocated linearly with 128 contiguous entries.
- *
- * In addition, a utf8Friendly MBCS file contains an additional
- *   uint16_t mbcsIndex[(maxFastUChar+1)>>6];
- * which replaces the stage 1 and 2 tables for indexing with bits from the
- * UTF-8 lead byte and middle trail byte. Unlike the older MBCS stage 2 table,
- * the mbcsIndex does not contain roundtrip flags. Therefore, all fallbacks
- * from code points up to maxFastUChar (and roundtrips to 0x00) are moved to
- * the extension data structure. This also allows for faster roundtrip
- * conversion from UTF-16.
- *
- * SBCS files do not contain an additional sbcsIndex[] array because the
- * proportional size increase would be noticeable, but the runtime
- * code builds one for the code point range for which the runtime conversion
- * code is optimized.
- *
- * For SBCS, maxFastUChar should be at least U+0FFF. The initial makeconv
- * implementation sets it to U+1FFF. Because the sbcsIndex is not stored in
- * the file, a larger maxFastUChar only affects stage 3 block allocation size
- * and is free in empty blocks. (Larger blocks with sparse contents cause larger
- * files.) U+1FFF includes almost all of the small scripts.
- * U+0FFF covers UTF-8 two-byte sequences and three-byte sequences starting with
- * 0xe0. This includes most scripts with legacy SBCS charsets.
- * The initial runtime implementation using 4.3 files only builds an sbcsIndex
- * for code points up to U+0FFF.
- *
- * For MBCS, maxFastUChar should be at least U+D7FF (=initial value).
- * This boundary is convenient because practically all of the commonly used
- * characters are below it, and because it is the boundary to surrogate
- * code points, above which special handling is necessary anyway.
- * (Surrogate pair assembly for UTF-16, validity checking for UTF-8.)
- *
- * maxFastUChar could be up to U+FFFF to cover the whole BMP, which could be
- * useful especially for conversion from UTF-8 when the input can be assumed
- * to be valid, because the surrogate range would then not have to be
- * checked.
- * (With maxFastUChar=0xffff, makeconv would have to check for mbcsIndex value
- * overflow because with the all-unassigned block 0 and nearly full mappings
- * from the BMP it is theoretically possible that an index into stage 3
- * exceeds 16 bits.)
- *
- * _MBCSHeader.version 4.2 adds an optional conversion extension data structure.
- * If it is present, then an ICU version reading header versions 4.0 or 4.1
- * will be able to use the base table and ignore the extension.
- *
- * The unicodeMask in the static data is part of the base table data structure.
- * Especially, the UCNV_HAS_SUPPLEMENTARY flag determines the length of the
- * fromUnicode stage 1 array.
- * The static data unicodeMask refers only to the base table's properties if
- * a base table is included.
- * In an extension-only file, the static data unicodeMask is 0.
- * The extension data indexes have a separate field with the unicodeMask flags.
- *
- * MBCS-style data structure following the static data.
- * Offsets are counted in bytes from the beginning of the MBCS header structure.
- * Details about usage in comments in ucnvmbcs.c.
- *
- * struct _MBCSHeader (see the definition in this header file below)
- * contains 32-bit fields as follows:
- * 8 values:
- *  0   uint8_t[4]  MBCS version in UVersionInfo format (currently 4.3.x.0)
- *  1   uint32_t    countStates

- * The trie data array is an array of uint16_t, uint32_t, or uint8_t,
- * specified via the UCPTrieValueWidth when building the trie.
- * The data array is 32-bit-aligned for uint32_t, otherwise 16-bit-aligned.
- * The overall length of the trie data is a multiple of 4 bytes.
- * (Padding is added at the end of the index array and/or near the end of the data array as needed.)
- *
- * The length of the data array (dataLength) is stored as an integer split across two fields
- * of the header struct (high bits in header.options).
- *
- * The trie type can be "fast" or "small" which determines the index structure,
- * specified via the UCPTrieType when building the trie.
- *
- * The type and valueWidth are stored in the header.options.
- * There are reserved type and valueWidth values, and reserved header.options bits.
- * They could be used in future format extensions.
- * Code reading the trie structure must fail with an error when unknown values or options are set.
- *
- * Values for ASCII character (U+0000..U+007F) can always be found at the start of the data array.
- *
- * Values for code points below a type-specific fast-indexing limit are found via two-stage lookup.
- * For a "fast" trie, the limit is the BMP/supplementary boundary at U+10000.
- * For a "small" trie, the limit is UCPTRIE_SMALL_MAX+1=U+1000.
- *
- * All code points in the range highStart..U+10FFFF map to a single highValue
- * which is stored at the second-to-last position of the data array.
- * (See UCPTRIE_HIGH_VALUE_NEG_DATA_OFFSET.)
- * The highStart value is header.shiftedHighStart<<UCPTRIE_SHIFT_2.
- * (UCPTRIE_SHIFT_2=9)
- *
- * Values for code points fast_limit..highStart-1 are found via four-stage lookup.
- * The data block size is smaller for this range than for the fast range.
- * This together with more index stages with small blocks makes this range
- * more easily compactable.
- *
- * There is also a trie error value stored at the last position of the data array.
- * (See UCPTRIE_ERROR_VALUE_NEG_DATA_OFFSET.)
- * It is intended to be returned for inputs that are not Unicode code points
- * (outside U+0000..U+10FFFF), or in string processing for ill-formed input
- * (unpaired surrogate in UTF-16, ill-formed UTF-8 subsequence).
- *
- * For a "fast" trie:
- *
- * The index array starts with the BMP index table for BMP code point lookup.
- * Its length is 1024=0x400.
- *
- * The supplementary index-1 table follows the BMP index table.
- * Variable length, for code points up to highStart-1.
- * Maximum length 64=0x40=0x100000>>UCPTRIE_SHIFT_1.
- * (For 0x100000 supplementary code points U+10000..U+10ffff.)
- *
- * After this index-1 table follow the variable-length index-3 and index-2 tables.
- *
- * The supplementary index tables are omitted completely
- * if there is only BMP data (highStart<=U+10000).
- *
- * For a "small" trie:
- *
- * The index array starts with a fast-index table for lookup of code points U+0000..U+0FFF.
- *
- * The "supplementary" index tables are always stored.
- * The index-1 table starts from U+0000, its maximum length is 68=0x44=0x110000>>UCPTRIE_SHIFT_1.
- *
- * For both trie types:
- *
- * The last index-2 block may be a partial block, storing indexes only for code points
- * below highStart.
- *
- * Lookup for ASCII code point c:
- *
- * Linear access from the start of the data array.
- *
- * value = data[c];
- *
- * Lookup for fast-range code point c:
- *
- * Shift the code point right by UCPTRIE_FAST_SHIFT=6 bits,
- * fetch the index array value at that offset,
- * add the lower code point bits, index into the data array.
- *
- * value = data[index[c>>6] + (c&0x3f)];
- *
- * (This works for ASCII as well.)
- *
- * Lookup for small-range code point c below highStart:
- *
- * Split the code point into four bit fields using several sets of shifts & masks
- * to read consecutive values from the index-1, index-2, index-3 and data tables.
- *
- * If all of the data block offsets in an index-3 block fit within 16 bits (up to 0xffff),
- * then the data block offsets are stored directly as uint16_t.
- *
- * Otherwise (this is very unusual but possible), the index-2 entry for the index-3 block
- * has bit 15 (0x8000) set, and each set of 8 index-3 entries is preceded by
- * an additional uint16_t word. Data block offsets are 18 bits wide, with the top 2 bits stored
- * in the additional word.
- *
- * See ucptrie_internalSmallIndex() for details.
- *
- * (In a "small" trie, this works for ASCII and below-fast_limit code points as well.)
- *
- * Compaction:
- *
- * Multiple code point ranges ("blocks") that are aligned on certain boundaries
- * (determined by the shifting/bit fields of code points) and
- * map to the same data values normally share a single subsequence of the data array.
- * Data blocks can also overlap partially.
- * (Depending on the builder code finding duplicate and overlapping blocks.)
- *
- * Iteration over same-value ranges:
- *
- * Range iteration (ucptrie_getRange()) walks the structure from a start code point
- * until some code point is found that maps to a different value;
- * the end of the returned range is just before that.
- *
- * The header.dataNullOffset (split across two header fields, high bits in header.options)
- * is the offset of a widely shared data block filled with one single value.
- * It helps quickly skip over large ranges of data with that value.
- * The builder must ensure that if the start of any data block (fast or small)
- * matches the dataNullOffset, then the whole block must be filled with the null value.
- * Special care must be taken if there is no fast null data block
- * but a small one, which is shorter, and it matches the *start* of some fast data block.
- *
- * Similarly, the header.index3NullOffset is the index-array offset of an index-3 block
- * where all index entries point to the dataNullOffset.
- * If there is no such data or index-3 block, then these offsets are set to
- * values that cannot be reached (data offset out of range/reserved index offset),
- * normally UCPTRIE_NO_DATA_NULL_OFFSET or UCPTRIE_NO_INDEX3_NULL_OFFSET respectively.

-*
-*   Notes on the organization of the ICU data implementation
-*
-*      All of the public API is defined in udata.h
-*
-*      The implementation is split into several files...
-*
-*         - udata.c  (this file) contains higher level code that knows about
-*                     the search paths for locating data, caching opened data, etc.
-*
-*         - umapfile.c  contains the low level platform-specific code for actually loading
-*                     (memory mapping, file reading, whatever) data into memory.
-*
-*         - ucmndata.c  deals with the tables of contents of ICU data items within
-*                     an ICU common format data file.  The implementation includes
-*                     an abstract interface and support for multiple TOC formats.
-*                     All knowledge of any specific TOC format is encapsulated here.
-*
-*         - udatamem.c has code for managing UDataMemory structs.  These are little
-*                     descriptor objects for blocks of memory holding ICU data of
-*                     various types.

- *    The UDataMemory objects returned to users will have the address of some desired
- *    data within the mapped region, but they wont have the mapping info itself, and thus
- *    won't cause anything to be removed from memory when they are closed.
- *
- *  For individual data files, the UDataMemory returned to the user holds the
- *  information necessary to unmap the data on close.  If the user independently
- *  opens the same data file twice, two completely independent mappings will be made.
- *  (There is no cache of opened data items from individual files, only a cache of
- *   opened Common Data files, that is, files containing a collection of data items.)
- *
- *  For common data passed in from the user via udata_setAppData() or
- *  udata_setCommonData(), ownership remains with the user.
- *
- *  UDataMemory objects themselves, as opposed to the memory they describe,
- *  can be anywhere - heap, stack/local or global.
- *  They have a flag to indicate when they're heap allocated and thus
- *  must be deleted when closed.

-/**
- * Function type for data transformation.
- * Transforms data, or just returns the length of the data if
- * the input length is -1.
- * Swap functions assume that their data pointers are aligned properly.
- *
- * Quick implementation outline:
- * (best to copy and adapt and existing swapper implementation)
- * check that the data looks like the expected format
- * if(length<0) {
- *   preflight:
- *   never dereference outData
- *   read inData and determine the data size
- *   assume that inData is long enough for this
- * } else {
- *   outData can be NULL if length==0
- *   inData==outData (in-place swapping) possible but not required!
- *   verify that length>=(actual size)
- *   if there is a chance that not every byte up to size is reached
- *     due to padding etc.:
- *   if(inData!=outData) {
- *     memcpy(outData, inData, actual size);
- *   }
- *   swap contents
- * }
- * return actual size
- *
- * Further implementation notes:
- * - read integers from inData before swapping them
- *   because in-place swapping can make them unreadable
- * - compareInvChars compares a local Unicode string with already-swapped
- *   output charset strings
- *
- * @param ds Pointer to UDataSwapper containing global data about the
- *           transformation and function pointers for handling primitive
- *           types.
- * @param inData Pointer to the input data to be transformed or examined.
- * @param length Length of the data, counting bytes. May be -1 for preflighting.
- *               If length>=0, then transform the data.
- *               If length==-1, then only determine the length of the data.
- *               The length cannot be determined from the data itself for all
- *               types of data (e.g., not for simple arrays of integers).
- * @param outData Pointer to the output data buffer.
- *                If length>=0 (transformation), then the output buffer must
- *                have a capacity of at least length.
- *                If length==-1, then outData will not be used and can be NULL.
- * @param pErrorCode ICU UErrorCode parameter, must not be NULL and must
- *                   fulfill U_SUCCESS on input.
- * @return The actual length of the data.

-/* This hashtable is implemented as a double hash.  All elements are
- * stored in a single array with no secondary storage for collision
- * resolution (no linked list, etc.).  When there is a hash collision
- * (when two unequal keys have the same hashcode) we resolve this by
- * using a secondary hash.  The secondary hash is an increment
- * computed as a hash function (a different one) of the primary
- * hashcode.  This increment is added to the initial hash value to
- * obtain further slots assigned to the same hash code.  For this to
- * work, the length of the array and the increment must be relatively
- * prime.  The easiest way to achieve this is to have the length of
- * the array be prime, and the increment be any value from
- * 1..length-1.
- *
- * Hashcodes are 32-bit integers.  We make sure all hashcodes are
- * non-negative by masking off the top bit.  This has two effects: (1)
- * modulo arithmetic is simplified.  If we allowed negative hashcodes,
- * then when we computed hashcode % length, we could get a negative
- * result, which we would then have to adjust back into range.  It's
- * simpler to just make hashcodes non-negative. (2) It makes it easy
- * to check for empty vs. occupied slots in the table.  We just mark
- * empty or deleted slots with a negative hashcode.
- *
- * The central function is _uhash_find().  This function looks for a
- * slot matching the given key and hashcode.  If one is found, it
- * returns a pointer to that slot.  If the table is full, and no match
- * is found, it returns NULL -- in theory.  This would make the code
- * more complicated, since all callers of _uhash_find() would then
- * have to check for a NULL result.  To keep this from happening, we
- * don't allow the table to fill.  When there is only one
- * empty/deleted slot left, uhash_put() will refuse to increase the
- * count, and fail.  This simplifies the code.  In practice, one will
- * seldom encounter this using default UHashtables.  However, if a
- * hashtable is set to a U_FIXED resize policy, or if memory is
- * exhausted, then the table may fill.
- *
- * High and low water ratios control rehashing.  They establish levels
- * of fullness (from 0 to 1) outside of which the data array is
- * reallocated and repopulated.  Setting the low water ratio to zero
- * means the table will never shrink.  Setting the high water ratio to
- * one means the table will never grow.  The ratios should be
- * coordinated with the ratio between successive elements of the
- * PRIMES table, so that when the primeIndex is incremented or
- * decremented during rehashing, it brings the ratio of count / length
- * back into the desired range (between low and high water ratios).

- * Look for a key in the table, or if no such key exists, the first

- * the keyComparator function.
- *
- * First find the start position, which is the hashcode modulo
- * the length.  Test it to see if it is:
- *
- * a. identical:  First check the hash values for a quick check,
- *    then compare keys for equality using keyComparator.
- * b. deleted
- * c. empty
- *
- * Stop if it is identical or empty, otherwise continue by adding a
- * "jump" value (moduloing by the length again to keep it within
- * range) and retesting.  For efficiency, there need enough empty
- * values so that the searchs stop within a reasonable amount of time.
- * This can be changed by changing the high/low water marks.
- *
- * In theory, this function can return NULL, if it is full (no empty
- * or deleted slots) and if no matching key is found.  In practice, we
- * prevent this elsewhere (in uhash_put) by making sure the last slot
- * in the table is never filled.
- *
- * The size of the table should be prime for this algorithm to work;
- * otherwise we are not guaranteed that the jump value (the secondary
- * hash) is relatively prime to the table length.

-/**
- * UHashtable stores key-value pairs and does moderately fast lookup
- * based on keys.  It provides a good tradeoff between access time and
- * storage space.  As elements are added to it, it grows to accomodate
- * them.  By default, the table never shrinks, even if all elements
- * are removed from it.
- *
- * Keys and values are stored as void* pointers.  These void* pointers
- * may be actual pointers to strings, objects, or any other structure
- * in memory, or they may simply be integral values cast to void*.
- * UHashtable doesn't care and manipulates them via user-supplied
- * functions.  These functions hash keys, compare keys, delete keys,
- * and delete values.  Some function pointers are optional (may be
- * NULL); others must be supplied.  Several prebuilt functions exist
- * to handle common key types.
- *
- * UHashtable ownership of keys and values is flexible, and controlled
- * by whether or not the key deleter and value deleter functions are
- * set.  If a void* key is actually a pointer to a deletable object,
- * then UHashtable can be made to delete that object by setting the
- * key deleter function pointer to a non-NULL value.  If this is done,
- * then keys passed to uhash_put() are owned by the hashtable and will
- * be deleted by it at some point, either as keys are replaced, or
- * when uhash_close() is finally called.  The same is true of values
- * and the value deleter function pointer.  Keys passed to methods
- * other than uhash_put() are never owned by the hashtable.
- *
- * NULL values are not allowed.  uhash_get() returns NULL to indicate
- * a key that is not in the table, and having a NULL value in the
- * table would generate an ambiguous result.  If a key and a NULL
- * value is passed to uhash_put(), this has the effect of doing a
- * uhash_remove() on that key.  This keeps uhash_get(), uhash_count(),
- * and uhash_nextElement() consistent with one another.
- *
- * To see everything in a hashtable, use uhash_nextElement() to
- * iterate through its contents.  Each call to this function returns a
- * UHashElement pointer.  A hash element contains a key, value, and
- * hashcode.  During iteration an element may be deleted by calling
- * uhash_removeElement(); iteration may safely continue thereafter.
- * The uhash_remove() function may also be safely called in
- * mid-iteration.  If uhash_put() is called during iteration,
- * the iteration is still guaranteed to terminate reasonably, but
- * there is no guarantee that every element will be returned or that
- * some won't be returned more than once.
- *
- * Under no circumstances should the UHashElement returned by
- * uhash_nextElement be modified directly.
- *
- * By default, the hashtable grows when necessary, but never shrinks,
- * even if all items are removed.  For most applications this is
- * optimal.  However, in a highly dynamic usage where memory is at a
- * premium, the table can be set to both grow and shrink by calling
- * uhash_setResizePolicy() with the policy U_GROW_AND_SHRINK.  In a
- * situation where memory is critical and the client wants a table
- * that does not grow at all, the constant U_FIXED can be used.

-/**
- * Table of language codes, both 2- and 3-letter, with preference
- * given to 2-letter codes where possible.  Includes 3-letter codes
- * that lack a 2-letter equivalent.
- *
- * This list must be in sorted order.  This list is returned directly
- * to the user by some API.
- *
- * This list must be kept in sync with LANGUAGES_3, with corresponding
- * entries matched.
- *
- * This table should be terminated with a NULL entry, followed by a
- * second list, and another NULL entry.  The first list is visible to
- * user code when this array is returned by API.  The second list
- * contains codes we support, but do not expose through user API.
- *
- * Notes
- *
- * Tables updated per http://lcweb.loc.gov/standards/iso639-2/ to
- * include the revisions up to 2001/7/27 *CWB*
- *
- * The 3 character codes are the terminology codes like RFC 3066.  This
- * is compatible with prior ICU codes
- *
- * "in" "iw" "ji" "jw" & "sh" have been withdrawn but are still in the
- * table but now at the end of the table because 3 character codes are
- * duplicates.  This avoids bad searches going from 3 to 2 character
- * codes.
- *
- * The range qaa-qtz is reserved for local use

-/**
- * UMutex - ICU Mutex class.
- *
- * This is the preferred Mutex class for use within ICU implementation code.
- * It is a thin wrapper over C++ std::mutex, with these additions:
- *    - Static instances are safe, not triggering static construction or destruction,
- *      and the associated order of construction or destruction issues.
- *    - Plumbed into u_cleanup() for destructing the underlying std::mutex,
- *      which frees any OS level resources they may be holding.
- *
- * Limitations:
- *    - Static or global instances only. Cannot be heap allocated. Cannot appear as a
- *      member of another class.
- *    - No condition variables or other advanced features. If needed, you will need to use
- *      std::mutex and std::condition_variable directly. For an example, see unifiedcache.cpp
- *
- * Typical Usage:
- *    static UMutex myMutex;
- *
- *    {
- *       Mutex lock(myMutex);
- *       ...    // Do stuff that is protected by myMutex;
- *    }         // myMutex is released when lock goes out of scope.

- * List of offsets from the current position from where to try matching
- * a code point or a string.
- * Store offsets rather than indexes to simplify the code and use the same list
- * for both increments (in span()) and decrements (in spanBack()).
- *
- * Assumption: The maximum offset is limited, and the offsets that are stored
- * at any one time are relatively dense, that is, there are normally no gaps of
- * hundreds or thousands of offset values.
- *
- * The implementation uses a circular buffer of byte flags,
- * each indicating whether the corresponding offset is in the list.
- * This avoids inserting into a sorted list of offsets (or absolute indexes) and
- * physically moving part of the list.
- *
- * Note: In principle, the caller should setMaxLength() to the maximum of the
- * max string length and U16_LENGTH/U8_LENGTH to account for
- * "long" single code points.
- * However, this implementation uses at least a staticList with more than
- * U8_LENGTH entries anyway.
- *
- * Note: If maxLength were guaranteed to be no more than 32 or 64,
- * the list could be stored as bit flags in a single integer.
- * Rather than handling a circular buffer with a start list index,
- * the integer would simply be shifted when lower offsets are removed.
- * UnicodeSet does not have a limit on the lengths of strings.

- *   + If a set string matches at the current position, then remember to continue after it.
- *   + Either recursively span for each code point or string match,
- *     or recursively span for all but the shortest one and

- *   + Remember the longest recursive span (the farthest end point).
- *   + If there is no match at the current position, neither for the code point there
- *     nor for any set string, then stop and return the longest recursive span length.
- *
- * Optimized implementation:
- *
- * (We assume that most sets will have very few very short strings.
- * A span using a string-less set is extremely fast.)
- *
- * Create and cache a spanSet which contains all of the single code points
- * of the original set but none of its strings.
- *
- * - Start with spanLength=spanSet.span(USET_SPAN_CONTAINED).
- * - Loop:
- *   + Try to match each set string at the end of the spanLength.
- *     ~ Set strings that start with set-contained code points must be matched
- *       with a partial overlap because the recursive algorithm would have tried
- *       to match them at every position.
- *     ~ Set strings that entirely consist of set-contained code points
- *       are irrelevant for span(USET_SPAN_CONTAINED) because the
- *       recursive algorithm would continue after them anyway
- *       and find the longest recursive match from their end.
- *     ~ Rather than recursing, note each end point of a set string match.
- *   + If no set string matched after spanSet.span(), then return
- *     with where the spanSet.span() ended.
- *   + If at least one set string matched after spanSet.span(), then
- *     pop the shortest string match end point and continue
- *     the loop, trying to match all set strings from there.
- *   + If at least one more set string matched after a previous string match,
- *     then test if the code point after the previous string match is also
- *     contained in the set.
- *     Continue the loop with the shortest end point of either this code point
- *     or a matching set string.
- *   + If no more set string matched after a previous string match,
- *     then try another spanLength=spanSet.span(USET_SPAN_CONTAINED).
- *     Stop if spanLength==0, otherwise continue the loop.
- *
- * By noting each end point of a set string match,
- * the function visits each string position at most once and finishes

- * Algorithm for spanNot()==span(USET_SPAN_NOT_CONTAINED)
- *
- * Theoretical algorithm:
- * - Iterate through the string, and at each code point boundary:
- *   + If the code point there is in the set, then return with the current position.
- *   + If a set string matches at the current position, then return with the current position.
- *
- * Optimized implementation:
- *
- * (Same assumption as for span() above.)
- *
- * Create and cache a spanNotSet which contains all of the single code points
- * of the original set but none of its strings.
- * For each set string add its initial code point to the spanNotSet.
- * (Also add its final code point for spanNotBack().)
- *
- * - Loop:
- *   + Do spanLength=spanNotSet.span(USET_SPAN_NOT_CONTAINED).
- *   + If the current code point is in the original set, then
- *     return the current position.
- *   + If any set string matches at the current position, then
- *     return the current position.
- *   + If there is no match at the current position, neither for the code point there
- *     nor for any set string, then skip this code point and continue the loop.
- *     This happens for set-string-initial code points that were added to spanNotSet
- *     when there is not actually a match for such a set string.

-/* compare canonically equivalent ------------------------------------------- */
-
-/*
- * Compare two strings for canonical equivalence.
- * Further options include case-insensitive comparison and
- * code point order (as opposed to code unit order).
- *
- * In this function, canonical equivalence is optional as well.
- * If canonical equivalence is tested, then both strings must fulfill
- * the FCD check.
- *
- * Semantically, this is equivalent to
- *   strcmp[CodePointOrder](NFD(foldCase(s1)), NFD(foldCase(s2)))
- * where code point order, NFD and foldCase are all optional.
- *
- * String comparisons almost always yield results before processing both strings
- * completely.
- * They are generally more efficient working incrementally instead of
- * performing the sub-processing (strlen, normalization, case-folding)
- * on the entire strings first.
- *
- * It is also unnecessary to not normalize identical characters.
- *
- * This function works in principle as follows:
- *
- * loop {
- *   get one code unit c1 from s1 (-1 if end of source)
- *   get one code unit c2 from s2 (-1 if end of source)
- *
- *   if(either string finished) {
- *     return result;
- *   }
- *   if(c1==c2) {
- *     continue;
- *   }
- *
- *   // c1!=c2
- *   try to decompose/case-fold c1/c2, and continue if one does;
- *
- *   // still c1!=c2 and neither decomposes/case-folds, return result
- *   return c1-c2;
- * }
- *
- * When a character decomposes, then the pointer for that source changes to
- * the decomposition, pushing the previous pointer onto a stack.
- * When the end of the decomposition is reached, then the code unit reader
- * pops the previous source from the stack.
- * (Same for case-folding.)
- *
- * This is complicated further by operating on variable-width UTF-16.
- * The top part of the loop works on code units, while lookups for decomposition
- * and case-folding need code points.
- * Code points are assembled after the equality/end-of-source part.
- * The source pointer is only advanced beyond all code units when the code point
- * actually decomposes/case-folds.
- *
- * If we were on a trail surrogate unit when assembling a code point,
- * and the code point decomposes/case-folds, then the decomposition/folding
- * result must be compared with the part of the other string that corresponds to
- * this string's lead surrogate.
- * Since we only assemble a code point when hitting a trail unit when the
- * preceding lead units were identical, we back up the other string by one unit
- * in such a case.
- *
- * The optional code point order comparison at the end works with
- * the same fix-up as the other code point order comparison functions.
- * See ustring.c and the comment near the end of this function.
- *
- * Assumption: A decomposition or case-folding result string never contains
- * a single surrogate. This is a safe assumption in the Unicode Standard.
- * Therefore, we do not need to check for surrogate pairs across
- * decomposition/case-folding boundaries.
- *
- * Further assumptions (see verifications tstnorm.cpp):
- * The API function checks for FCD first, while the core function
- * first case-folds and then decomposes. This requires that case-folding does not
- * un-FCD any strings.
- *
- * The API function may also NFD the input and turn off decomposition.
- * This requires that case-folding does not un-NFD strings either.
- *
- * TODO If any of the above two assumptions is violated,
- * then this entire code must be re-thought.
- * If this happens, then a simple solution is to case-fold both strings up front
- * and to turn off UNORM_INPUT_IS_FCD.
- * We already do this when not both strings are in FCD because makeFCD
- * would be a partial NFD before the case folding, which does not work.
- * Note that all of this is only a problem when case-folding _and_
- * canonical equivalence come together.
- * (Comments in unorm_compare() are more up to date than this TODO.)

- * Description of the format of unorm.icu version 2.3.
- *
- * Main change from version 1 to version 2:
- * Use of new, common UTrie instead of normalization-specific tries.
- * Change to version 2.1: add third/auxiliary trie with associated data.
- * Change to version 2.2: add skippable (f) flag data (_NORM_AUX_NFC_SKIP_F_MASK).
- * Change to version 2.3: add serialized sets for normalization exclusions
- *                        stored inside canonStartSets[]
- *
- * For more details of how to use the data structures see the code
- * in unorm.cpp (runtime normalization code) and
- * in gennorm.c and gennorm/store.c (build-time data generation).
- *
- * For the serialized format of UTrie see utrie.c/UTrieHeader.
- *
- * - Overall partition
- *
- * unorm.dat customarily begins with a UDataInfo structure, see udata.h and .c.
- * After that there are the following structures:
- *
- * int32_t indexes[_NORM_INDEX_TOP];            -- _NORM_INDEX_TOP=32, see enum in this file
- *
- * UTrie normTrie;                              -- size in bytes=indexes[_NORM_INDEX_TRIE_SIZE]
- * 
- * uint16_t extraData[extraDataTop];            -- extraDataTop=indexes[_NORM_INDEX_UCHAR_COUNT]
- *                                                 extraData[0] contains the number of units for
- *                                                 FC_NFKC_Closure (formatVersion>=2.1)
- *
- * uint16_t combiningTable[combiningTableTop];  -- combiningTableTop=indexes[_NORM_INDEX_COMBINE_DATA_COUNT]
- *                                                 combiningTableTop may include one 16-bit padding unit
- *                                                 to make sure that fcdTrie is 32-bit-aligned
- *
- * UTrie fcdTrie;                               -- size in bytes=indexes[_NORM_INDEX_FCD_TRIE_SIZE]
- *
- * UTrie auxTrie;                               -- size in bytes=indexes[_NORM_INDEX_AUX_TRIE_SIZE]
- *
- * uint16_t canonStartSets[canonStartSetsTop]   -- canonStartSetsTop=indexes[_NORM_INDEX_CANON_SET_COUNT]
- *                                                 serialized USets and binary search tables, see below
- *
- *
- * The indexes array contains lengths and sizes of the following arrays and structures
- * as well as the following values:
- *  indexes[_NORM_INDEX_COMBINE_FWD_COUNT]=combineFwdTop
- *      -- one more than the highest combining index computed for forward-only-combining characters
- *  indexes[_NORM_INDEX_COMBINE_BOTH_COUNT]=combineBothTop-combineFwdTop
- *      -- number of combining indexes computed for both-ways-combining characters
- *  indexes[_NORM_INDEX_COMBINE_BACK_COUNT]=combineBackTop-combineBothTop
- *      -- number of combining indexes computed for backward-only-combining characters
- *
- *  indexes[_NORM_INDEX_MIN_NF*_NO_MAYBE] (where *={ C, D, KC, KD })
- *      -- first code point with a quick check NF* value of NO/MAYBE
- *
- *
- * - Tries
- *
- * The main structures are two UTrie tables ("compact arrays"),
- * each with one index array and one data array.
- * See utrie.h and utrie.c.
- *
- *
- * - Tries in unorm.dat
- *
- * The first trie (normTrie above)
- * provides data for the NF* quick checks and normalization.
- * The second trie (fcdTrie above) provides data just for FCD checks.
- *
- *
- * - norm32 data words from the first trie
- *
- * The norm32Table contains one 32-bit word "norm32" per code point.
- * It contains the following bit fields:
- * 31..16   extra data index, _NORM_EXTRA_SHIFT is used to shift this field down
- *          if this index is <_NORM_EXTRA_INDEX_TOP then it is an index into
- *              extraData[] where variable-length normalization data for this
- *              code point is found
- *          if this index is <_NORM_EXTRA_INDEX_TOP+_NORM_EXTRA_SURROGATE_TOP
- *              then this is a norm32 for a leading surrogate, and the index
- *              value is used together with the following trailing surrogate
- *              code unit in the second trie access
- *          if this index is >=_NORM_EXTRA_INDEX_TOP+_NORM_EXTRA_SURROGATE_TOP
- *              then this is a norm32 for a "special" character,
- *              i.e., the character is a Hangul syllable or a Jamo
- *              see _NORM_EXTRA_HANGUL etc.
- *          generally, instead of extracting this index from the norm32 and
- *              comparing it with the above constants,
- *              the normalization code compares the entire norm32 value
- *              with _NORM_MIN_SPECIAL, _NORM_SURROGATES_TOP, _NORM_MIN_HANGUL etc.
- *
- * 15..8    combining class (cc) according to UnicodeData.txt
- *
- *  7..6    _NORM_COMBINES_ANY flags, used in composition to see if a character
- *              combines with any following or preceding character(s)
- *              at all
- *     7    _NORM_COMBINES_BACK
- *     6    _NORM_COMBINES_FWD
- *
- *  5..0    quick check flags, set for "no" or "maybe", with separate flags for
- *              each normalization form
- *              the higher bits are "maybe" flags; for NF*D there are no such flags
- *              the lower bits are "no" flags for all forms, in the same order
- *              as the "maybe" flags,
- *              which is (MSB to LSB): NFKD NFD NFKC NFC
- *  5..4    _NORM_QC_ANY_MAYBE
- *  3..0    _NORM_QC_ANY_NO
- *              see further related constants
- *
- *
- * - Extra data per code point
- *
- * "Extra data" is referenced by the index in norm32.
- * It is variable-length data. It is only present, and only those parts
- * of it are, as needed for a given character.
- * The norm32 extra data index is added to the beginning of extraData[]
- * to get to a vector of 16-bit words with data at the following offsets:
- *
- * [-1]     Combining index for composition.
- *              Stored only if norm32&_NORM_COMBINES_ANY .
- * [0]      Lengths of the canonical and compatibility decomposition strings.
- *              Stored only if there are decompositions, i.e.,
- *              if norm32&(_NORM_QC_NFD|_NORM_QC_NFKD)
- *          High byte: length of NFKD, or 0 if none
- *          Low byte: length of NFD, or 0 if none
- *          Each length byte also has another flag:
- *              Bit 7 of a length byte is set if there are non-zero
- *              combining classes (cc's) associated with the respective
- *              decomposition. If this flag is set, then the decomposition
- *              is preceded by a 16-bit word that contains the
- *              leading and trailing cc's.
- *              Bits 6..0 of a length byte are the length of the
- *              decomposition string, not counting the cc word.
- * [1..n]   NFD
- * [n+1..]  NFKD
- *
- * Each of the two decompositions consists of up to two parts:
- * - The 16-bit words with the leading and trailing cc's.
- *   This is only stored if bit 7 of the corresponding length byte
- *   is set. In this case, at least one of the cc's is not zero.
- *   High byte: leading cc==cc of the first code point in the decomposition string
- *   Low byte: trailing cc==cc of the last code point in the decomposition string
- * - The decomposition string in UTF-16, with length code units.
- *
- *
- * - Combining indexes and combiningTable[]
- *
- * Combining indexes are stored at the [-1] offset of the extra data
- * if the character combines forward or backward with any other characters.
- * They are used for (re)composition in NF*C.
- * Values of combining indexes are arranged according to whether a character
- * combines forward, backward, or both ways:
- *    forward-only < both ways < backward-only
- *
- * The index values for forward-only and both-ways combining characters
- * are indexes into the combiningTable[].
- * The index values for backward-only combining characters are simply
- * incremented from the preceding index values to be unique.
- *
- * In the combiningTable[], a variable-length list
- * of variable-length (back-index, code point) pair entries is stored
- * for each forward-combining character.
- *
- * These back-indexes are the combining indexes of both-ways or backward-only
- * combining characters that the forward-combining character combines with.
- *
- * Each list is sorted in ascending order of back-indexes.
- * Each list is terminated with the last back-index having bit 15 set.
- *
- * Each pair (back-index, code point) takes up either 2 or 3
- * 16-bit words.
- * The first word of a list entry is the back-index, with its bit 15 set if
- * this is the last pair in the list.
- *
- * The second word contains flags in bits 15..13 that determine
- * if there is a third word and how the combined character is encoded:
- * 15   set if there is a third word in this list entry
- * 14   set if the result is a supplementary character
- * 13   set if the result itself combines forward
- *
- * According to these bits 15..14 of the second word,
- * the result character is encoded as follows:
- * 00 or 01 The result is <=0x1fff and stored in bits 12..0 of
- *          the second word.
- * 10       The result is 0x2000..0xffff and stored in the third word.
- *          Bits 12..0 of the second word are not used.
- * 11       The result is a supplementary character.
- *          Bits 9..0 of the leading surrogate are in bits 9..0 of
- *          the second word.
- *          Add 0xd800 to these bits to get the complete surrogate.
- *          Bits 12..10 of the second word are not used.
- *          The trailing surrogate is stored in the third word.
- *
- *
- * - FCD trie
- *
- * The FCD trie is very simple.
- * It is a folded trie with 16-bit data words.
- * In each word, the high byte contains the leading cc of the character,
- * and the low byte contains the trailing cc of the character.
- * These cc's are the cc's of the first and last code points in the
- * canonical decomposition of the character.
- *
- * Since all 16 bits are used for cc's, lead surrogates must be tested
- * by checking the code unit instead of the trie data.
- * This is done only if the 16-bit data word is not zero.
- * If the code unit is a leading surrogate and the data word is not zero,
- * then instead of cc's it contains the offset for the second trie lookup.
- *
- *
- * - Auxiliary trie and data
- *
- * The auxiliary 16-bit trie contains data for additional properties.
- * Bits
- * 15..13   reserved
- *     12   not NFC_Skippable (f) (formatVersion>=2.2)
- *     11   flag: not a safe starter for canonical closure
- *     10   composition exclusion
- *  9.. 0   index into extraData[] to FC_NFKC_Closure string
- *          (not for lead surrogate),
- *          or lead surrogate offset (for lead surrogate, if 9..0 not zero)
- *
- * - FC_NFKC_Closure strings in extraData[]
- *
- * Strings are either stored as a single code unit or as the length
- * followed by that many units.
- *   const UChar *s=extraData+(index from auxTrie data bits 9..0);
- *   int32_t length;
- *   if(*s<0xff00) {
- *     // s points to the single-unit string
- *     length=1;
- *   } else {
- *     length=*s&0xff;
- *     ++s;
- *   }
- *
- * Conditions for "NF* Skippable" from Mark Davis' com.ibm.text.UCD.NFSkippable:
- * (used in NormalizerTransliterator)
- *
- * A skippable character is
- * a) unassigned, or ALL of the following:
- * b) of combining class 0.
- * c) not decomposed by this normalization form.
- * AND if NFC or NFKC,
- * d) can never compose with a previous character.
- * e) can never compose with a following character.
- * f) can never change if another character is added.
- *    Example: a-breve might satisfy all but f, but if you
- *    add an ogonek it changes to a-ogonek + breve
- *
- * a)..e) must be tested from norm32.
- * Since f) is more complicated, the (not-)NFC_Skippable flag (f) is built
- * into the auxiliary trie.
- * The same bit is used for NFC and NFKC; (c) differs for them.
- * As usual, we build the "not skippable" flags so that unassigned
- * code points get a 0 bit.
- * This bit is only valid after (a)..(e) test FALSE; test NFD_NO before (f) as well.
- * Test Hangul LV syllables entirely in code.
- *
- *
- * - structure inside canonStartSets[]
- *
- * This array maps from code points c to sets of code points (USerializedSet).
- * The result sets are the code points whose canonical decompositions start
- * with c.
- *
- * canonStartSets[] contains the following sub-arrays:
- *
- * indexes[_NORM_SET_INDEX_TOP]
- *   - contains lengths of sub-arrays etc.
- *
- * startSets[indexes[_NORM_SET_INDEX_CANON_SETS_LENGTH]-_NORM_SET_INDEX_TOP]
- *   - contains serialized sets (USerializedSet) of canonical starters for
- *     enumerating canonically equivalent strings
- *     indexes[_NORM_SET_INDEX_CANON_SETS_LENGTH] includes _NORM_SET_INDEX_TOP
- *     for details about the structure see uset.c
- *
- * bmpTable[indexes[_NORM_SET_INDEX_CANON_BMP_TABLE_LENGTH]]
- *   - a sorted search table for BMP code points whose results are
- *     either indexes to USerializedSets or single code points for
- *     single-code point sets;
- *     each entry is a pair of { code point, result } with result=(binary) yy xxxxxx xxxxxxxx
- *     if yy==01 then there is a USerializedSet at canonStartSets+x
- *     else build a USerializedSet with result as the single code point
- *
- * suppTable[indexes[_NORM_SET_INDEX_CANON_SUPP_TABLE_LENGTH]]
- *   - a sorted search table for supplementary code points whose results are
- *     either indexes to USerializedSets or single code points for
- *     single-code point sets;
- *     each entry is a triplet of { high16(cp), low16(cp), result }
- *     each code point's high-word may contain extra data in bits 15..5:
- *     if the high word has bit 15 set, then build a set with a single code point
- *     which is (((high16(cp)&0x1f00)<<8)|result;
- *     else there is a USerializedSet at canonStartSets+result
- *
- * FormatVersion 2.3 adds 2 serialized sets for normalization exclusions.
- * They are stored in the data file so that the runtime normalization code need
- * not depend on other properties and their data and implementation files.
- * The _NORM_SET_INDEX_NX_..._OFFSET offsets in the canonStartSets index table
- * give the location for each set.
- * There is no set stored for UNORM_NX_HANGUL because it's trivial to create
- * without using properties.
- *
- * Set contents:
- *
- * _NORM_SET_INDEX_NX_CJK_COMPAT_OFFSET (for UNORM_NX_CJK_COMPAT)
- *     [[:Ideographic:]&[:NFD_QC=No:]]
- *     =[CJK Ideographs]&[has canonical decomposition]
- *
- * _NORM_SET_INDEX_NX_UNICODE32_OFFSET (for UNORM_UNICODE_3_2)
- *     [:^Age=3.2:]
- *     =set with all code points that were not designated by the specified Unicode version
- *
- * _NORM_SET_INDEX_NX_RESERVED_OFFSET
- *     This is an offset that points to where the next, future set would start.
- *     Currently it indicates where the previous set ends, and thus its length.
- *     The name for this enum constant may in the future be applied to different
- *     index slots. In order to get the limit of a set, use its index slot and
- *     the immediately following one regardless of that one's enum name.

- * Default implementation of UMemory::new/delete
- * using uprv_malloc() and uprv_free().
- *
- * For testing, this is used together with a list of imported symbols to verify
- * that ICU is not using the global ::new and ::delete operators.
- *
- * These operators can be implemented like this or any other appropriate way
- * when customizing ICU for certain environments.
- * Whenever ICU is customized in binary incompatible ways please be sure
- * to use library name suffixes to distinguish such libraries from
- * the standard build.
- *
- * Instead of just modifying these C++ new/delete operators, it is usually best
- * to modify the uprv_malloc()/uprv_free()/uprv_realloc() functions in cmemory.c.
- *
- * Memory test on Windows/MSVC 6:
- * The global operators new and delete look as follows:
- *   04F 00000000 UNDEF  notype ()    External     | ??2@YAPAXI@Z (void * __cdecl operator new(unsigned int))
- *   03F 00000000 UNDEF  notype ()    External     | ??3@YAXPAX@Z (void __cdecl operator delete(void *))
- *
- * These lines are from output generated by the MSVC 6 tool dumpbin with
- * dumpbin /symbols *.obj
- *
- * ??2@YAPAXI@Z and ??3@YAXPAX@Z are the linker symbols in the .obj
- * files and are imported from msvcrtd.dll (in a debug build).
- *
- * Make sure that with the UMemory operators new and delete defined these two symbols
- * do not appear in the dumpbin /symbols output for the ICU libraries!
- *
- * If such a symbol appears in the output then look in the preceding lines in the output
- * for which file and function calls the global new or delete operator,
- * and replace with uprv_malloc/uprv_free.

- *
- * ICU 56: New in formatVersion 3 compared with 2: -------------
- *
- * Resource bundles can optionally use shared string-v2 values
- * stored in the pool bundle.
- * If so, then the indexes[] contain two new values
- * in previously-unused bits of existing indexes[] slots:
- * - poolStringIndexLimit:
- *     String-v2 offsets (in 32-bit Resource words) below this limit
- *     point to pool bundle string-v2 values.
- * - poolStringIndex16Limit:
- *     Resource16 string-v2 offsets below this limit
- *     point to pool bundle string-v2 values.
- * Guarantee: poolStringIndex16Limit <= poolStringIndexLimit
- *
- * The local bundle's poolStringIndexLimit is greater than
- * any pool bundle string index used in the local bundle.
- * The poolStringIndexLimit should not be greater than
- * the maximum possible pool bundle string index.
- *
- * The maximum possible pool bundle string index is the index to the last non-NUL
- * pool string character, due to suffix sharing.
- *
- * In the pool bundle, there is no structure that lists the strings.
- * (The root resource is an empty Table.)
- * If the strings need to be enumerated (as genrb --usePoolBundle does),
- * then iterate through the pool bundle's 16-bit-units array from the beginning.
- * Stop at the end of the array, or when an explicit or implicit string length
- * would lead beyond the end of the array,
- * or when an apparent string is not NUL-terminated.
- * (Future genrb version might terminate the strings with
- * what looks like a large explicit string length.)
- *
- * ICU 4.4: New in formatVersion 2 compared with 1.3: -------------
- *
- * Three new resource types -- String-v2, Table16 and Array16 -- have their
- * values stored in a new array of 16-bit units between the table key strings
- * and the start of the other resources.
- *
- * genrb eliminates duplicates among Unicode string-v2 values.
- * Multiple Unicode strings may use the same offset and string data,
- * or a short string may point to the suffix of a longer string. ("Suffix sharing")
- * For example, one string "abc" may be reused for another string "bc" by pointing
- * to the second character. (Short strings-v2 are NUL-terminated
- * and not preceded by an explicit length value.)
- *
- * It is allowed for all resource types to share values.
- * The swapper code (ures_swap()) has been modified so that it swaps each item
- * exactly once.
- *
- * A resource bundle may use a special pool bundle. Some or all of the table key strings
- * of the using-bundle are omitted, and the key string offsets for such key strings refer
- * to offsets in the pool bundle.
- * The using-bundle's and the pool-bundle's indexes[URES_INDEX_POOL_CHECKSUM] values
- * must match.
- * Two bits in indexes[URES_INDEX_ATTRIBUTES] indicate whether a resource bundle
- * is or uses a pool bundle.
- *
- * Table key strings must be compared in ASCII order, even if they are not
- * stored in ASCII.
- *
- * New in formatVersion 1.3 compared with 1.2: -------------
- *
- * genrb eliminates duplicates among key strings.
- * Multiple table items may share one key string, or one item may point
- * to the suffix of another's key string. ("Suffix sharing")
- * For example, one key "abc" may be reused for another key "bc" by pointing
- * to the second character. (Key strings are NUL-terminated.)
- *
- * -------------
- *
- * An ICU4C resource bundle file (.res) is a binary, memory-mappable file
- * with nested, hierarchical data structures.
- * It physically contains the following:
- *
- *   Resource root; -- 32-bit Resource item, root item for this bundle's tree;
- *                     currently, the root item must be a table or table32 resource item
- *   int32_t indexes[indexes[0]]; -- array of indexes for friendly
- *                                   reading and swapping; see URES_INDEX_* above
- *                                   new in formatVersion 1.1 (ICU 2.8)
- *   char keys[]; -- characters for key strings
- *                   (formatVersion 1.0: up to 65k of characters; 1.1: <2G)
- *                   (minus the space for root and indexes[]),
- *                   which consist of invariant characters (ASCII/EBCDIC) and are NUL-terminated;
- *                   padded to multiple of 4 bytes for 4-alignment of the following data
- *   uint16_t 16BitUnits[]; -- resources that are stored entirely as sequences of 16-bit units
- *                             (new in formatVersion 2/ICU 4.4)
- *                             data is indexed by the offset values in 16-bit resource types,
- *                             with offset 0 pointing to the beginning of this array;
- *                             there is a 0 at offset 0, for empty resources;
- *                             padded to multiple of 4 bytes for 4-alignment of the following data
- *   data; -- data directly and indirectly indexed by the root item;
- *            the structure is determined by walking the tree
- *
- * Each resource bundle item has a 32-bit Resource handle (see typedef above)
- * which contains the item type number in its upper 4 bits (31..28) and either
- * an offset or a direct value in its lower 28 bits (27..0).
- * The order of items is undefined and only determined by walking the tree.
- * Leaves of the tree may be stored first or last or anywhere in between,
- * and it is in theory possible to have unreferenced holes in the file.
- *
- * 16-bit-unit values:
- * Starting with formatVersion 2/ICU 4.4, some resources are stored in a special
- * array of 16-bit units. Each resource value is a sequence of 16-bit units,
- * with no per-resource padding to a 4-byte boundary.
- * 16-bit container types (Table16 and Array16) contain Resource16 values
- * which are offsets to String-v2 resources in the same 16-bit-units array.
- *
- * Direct values:
- * - Empty Unicode strings have an offset value of 0 in the Resource handle itself.
- * - Starting with formatVersion 2/ICU 4.4, an offset value of 0 for
- *   _any_ resource type indicates an empty value.
- * - Integer values are 28-bit values stored in the Resource handle itself;
- *   the interpretation of unsigned vs. signed integers is up to the application.
- *
- * All other types and values use 28-bit offsets to point to the item's data.
- * The offset is an index to the first 32-bit word of the value, relative to the
- * start of the resource data (i.e., the root item handle is at offset 0).
- * To get byte offsets, the offset is multiplied by 4 (or shifted left by 2 bits).
- * All resource item values are 4-aligned.
- *
- * New in formatVersion 2/ICU 4.4: Some types use offsets into the 16-bit-units array,
- * indexing 16-bit units in that array.
- *
- * The structures (memory layouts) for the values for each item type are listed
- * in the table below.
- *
- * Nested, hierarchical structures: -------------
- *
- * Table items contain key-value pairs where the keys are offsets to char * key strings.
- * The values of these pairs are either Resource handles or
- * offsets into the 16-bit-units array, depending on the table type.
- *
- * Array items are simple vectors of Resource handles,
- * or of offsets into the 16-bit-units array, depending on the array type.
- *
- * Table key string offsets: -------
- *
- * Key string offsets are relative to the start of the resource data (of the root handle),
- * i.e., the first string has an offset of 4+sizeof(indexes).
- * (After the 4-byte root handle and after the indexes array.)
- *
- * If the resource bundle uses a pool bundle, then some key strings are stored
- * in the pool bundle rather than in the local bundle itself.
- * - In a Table or Table16, the 16-bit key string offset is local if it is
- *   less than indexes[URES_INDEX_KEYS_TOP]<<2.
- *   Otherwise, subtract indexes[URES_INDEX_KEYS_TOP]<<2 to get the offset into
- *   the pool bundle key strings.
- * - In a Table32, the 32-bit key string offset is local if it is non-negative.
- *   Otherwise, reset bit 31 to get the pool key string offset.
- *
- * Unlike the local offset, the pool key offset is relative to
- * the start of the key strings, not to the start of the bundle.
- *
- * An alias item is special (and new in ICU 2.4): --------------
- *
- * Its memory layout is just like for a UnicodeString, but at runtime it resolves to
- * another resource bundle's item according to the path in the string.
- * This is used to share items across bundles that are in different lookup/fallback
- * chains (e.g., large collation data among zh_TW and zh_HK).
- * This saves space (for large items) and maintenance effort (less duplication of data).
- *
- * --------------------------------------------------------------------------
- *
- * Resource types:
- *
- * Most resources have their values stored at four-byte offsets from the start
- * of the resource data. These values are at least 4-aligned.
- * Some resource values are stored directly in the offset field of the Resource itself.
- * See UResType in unicode/ures.h for enumeration constants for Resource types.
- *
- * Some resources have their values stored as sequences of 16-bit units,
- * at 2-byte offsets from the start of a contiguous 16-bit-unit array between
- * the table key strings and the other resources. (new in formatVersion 2/ICU 4.4)
- * At offset 0 of that array is a 16-bit zero value for empty 16-bit resources.
- *
- * Resource16 values in Table16 and Array16 are 16-bit offsets to String-v2
- * resources, with the offsets relative to the start of the 16-bit-units array.
- * Starting with formatVersion 3/ICU 56, if offset<poolStringIndex16Limit
- * then use the pool bundle's 16-bit-units array,
- * otherwise subtract that limit and use the local 16-bit-units array.
- *
- * Type Name            Memory layout of values
- *                      (in parentheses: scalar, non-offset values)
- *
- * 0  Unicode String:   int32_t length, UChar[length], (UChar)0, (padding)
- *                  or  (empty string ("") if offset==0)
- * 1  Binary:           int32_t length, uint8_t[length], (padding)
- *                      - the start of the bytes is 16-aligned -
- * 2  Table:            uint16_t count, uint16_t keyStringOffsets[count], (uint16_t padding), Resource[count]
- * 3  Alias:            (physically same value layout as string, new in ICU 2.4)
- * 4  Table32:          int32_t count, int32_t keyStringOffsets[count], Resource[count]
- *                      (new in formatVersion 1.1/ICU 2.8)
- * 5  Table16:          uint16_t count, uint16_t keyStringOffsets[count], Resource16[count]
- *                      (stored in the 16-bit-units array; new in formatVersion 2/ICU 4.4)
- * 6  Unicode String-v2:UChar[length], (UChar)0; length determined by the first UChar:
- *                      - if first is not a trail surrogate, then the length is implicit
- *                        and u_strlen() needs to be called
- *                      - if first<0xdfef then length=first&0x3ff (and skip first)
- *                      - if first<0xdfff then length=((first-0xdfef)<<16) | second UChar
- *                      - if first==0xdfff then length=((second UChar)<<16) | third UChar
- *                      (stored in the 16-bit-units array; new in formatVersion 2/ICU 4.4)
- *
- *                      Starting with formatVersion 3/ICU 56, if offset<poolStringIndexLimit
- *                      then use the pool bundle's 16-bit-units array,
- *                      otherwise subtract that limit and use the local 16-bit-units array.
- *                      (Note different limits for Resource16 vs. Resource.)
- *
- * 7  Integer:          (28-bit offset is integer value)
- * 8  Array:            int32_t count, Resource[count]
- * 9  Array16:          uint16_t count, Resource16[count]
- *                      (stored in the 16-bit-units array; new in formatVersion 2/ICU 4.4)
- * 14 Integer Vector:   int32_t length, int32_t[length]
- * 15 Reserved:         This value denotes special purpose resources and is for internal use.
- *
- * Note that there are 3 types with data vector values:
- * - Vectors of 8-bit bytes stored as type Binary.
- * - Vectors of 16-bit words stored as type Unicode String or Unicode String-v2
- *                     (no value restrictions, all values 0..ffff allowed!).
- * - Vectors of 32-bit words stored as type Integer Vector.

-/**
- * <code>UScriptRun</code> is used to find runs of characters in
- * the same script. It implements a simple iterator over an array
- * of characters. The iterator will resolve script-neutral characters
- * like punctuation into the script of the surrounding characters.
- *
- * The iterator will try to match paired punctuation. If it sees an
- * opening punctuation character, it will remember the script that
- * was assigned to that character, and assign the same script to the
- * matching closing punctuation.
- *
- * Scripts are chosen based on the <code>UScriptCode</code> enumeration.
- * No attempt is made to combine related scripts into a single run. In
- * particular, Hiragana, Katakana, and Han characters will appear in seperate
- * runs.
-
- * Here is an example of how to iterate over script runs:
- * <pre>
- * \code
- * void printScriptRuns(const UChar *text, int32_t length)
- * {
- *     UErrorCode error = U_ZERO_ERROR;
- *     UScriptRun *scriptRun = uscript_openRun(text, testLength, &error);
- *     int32_t start = 0, limit = 0;
- *     UScriptCode code = USCRIPT_INVALID_CODE;
- *
- *     while (uscript_nextRun(&start, &limit, &code)) {
- *         printf("Script '%s' from %d to %d.\n", uscript_getName(code), start, limit);
- *     }

-
-       2) If a string contains any RandALCat character, the string MUST NOT
-          contain any LCat character.
-
-       3) If a string contains any RandALCat character, a RandALCat
-          character MUST be the first character of the string, and a
-          RandALCat character MUST be the last character of the string.

-*   file name:  utracimp.h
-*   encoding:   UTF-8
-*   tab size:   8 (not used)
-*   indentation:4
-*
-*   created on: 2003aug06
-*   created by: Markus W. Scherer
-*
-*   Internal header for ICU tracing/logging.
-*
-*
-*   Various notes:
-*   - using a trace level variable to only call trace functions
-*     when the level is sufficient
-*   - using the same variable for tracing on/off to never make a function
-*     call when off
-*   - the function number is put into a local variable by the entry macro
-*     and used implicitly to avoid copy&paste/typing mistakes by the developer
-*   - the application must call utrace_setFunctions() and pass in
-*     implementations for the trace functions
-*   - ICU trace macros call ICU functions that route through the function
-*     pointers if they have been set;
-*     this avoids an indirection at the call site
-*     (which would cost more code for another check and for the indirection)
-*
-*   ### TODO Issues:
-*   - Verify that va_list is portable among compilers for the same platform.
-*     va_list should be portable because printf() would fail otherwise!
-*   - Should enum values like UTraceLevel be passed into int32_t-type arguments,
-*     or should enum types be used?

-/**
- * \file
- *
- * This is a common implementation of a "folded" trie.
- * It is a kind of compressed, serializable table of 16- or 32-bit values associated with
- * Unicode code points (0..0x10ffff).
- *
- * This implementation is optimized for getting values while walking forward
- * through a UTF-16 string.
- * Therefore, the simplest and fastest access macros are the
- * _FROM_LEAD() and _FROM_OFFSET_TRAIL() macros.
- *

-/**
- * \file
- *
- * This is a common implementation of a Unicode trie.
- * It is a kind of compressed, serializable table of 16- or 32-bit values associated with
- * Unicode code points (0..0x10ffff). (A map from code points to integers.)
- *
- * This is the second common version of a Unicode trie (hence the name UTrie2).
- * Compared with UTrie version 1:
- * - Still splitting BMP code points 11:5 bits for index and data table lookups.
- * - Still separate data for lead surrogate code _units_ vs. code _points_,
- *   but the lead surrogate code unit values are not required any more
- *   for data lookup for supplementary code points.
- * - The "folding" mechanism is removed. In UTrie version 1, this somewhat
- *   hard-to-explain mechanism was meant to be used for optimized UTF-16
- *   processing, with application-specific encoding of indexing bits
- *   in the lead surrogate data for the associated supplementary code points.
- * - For the last single-value code point range (ending with U+10ffff),
- *   the starting code point ("highStart") and the value are stored.
- * - For supplementary code points U+10000..highStart-1 a three-table lookup
- *   (two index tables and one data table) is used. The first index
- *   is truncated, omitting both the BMP portion and the high range.

-/* Implementation notes ----------------------------------------------------- */
-
-/*
- * The UTRIE2_SHIFT_1, UTRIE2_SHIFT_2, UTRIE2_INDEX_SHIFT and other values
- * have been chosen to minimize trie sizes overall.
- * Most of the code is flexible enough to work with a range of values,
- * within certain limits.
- *
- * Exception: Support for separate values for lead surrogate code _units_
- * vs. code _points_ was added after the constants were fixed,
- * and has not been tested nor particularly designed for different constant values.
- * (Especially the utrie2_enum() code that jumps to the special LSCP index-2
- * part and back.)
- *
- * Requires UTRIE2_SHIFT_2<=6. Otherwise 0xc0 which is the top of the ASCII-linear data
- * including the bad-UTF-8-data block is not a multiple of UTRIE2_DATA_BLOCK_LENGTH
- * and map[block>>UTRIE2_SHIFT_2] (used in reference counting and compaction
- * remapping) stops working.
- *
- * Requires UTRIE2_SHIFT_1>=10 because utrie2_enumForLeadSurrogate()
- * assumes that a single index-2 block is used for 0x400 code points
- * corresponding to one lead surrogate.
- *
- * Requires UTRIE2_SHIFT_1<=16. Otherwise one single index-2 block contains
- * more than one Unicode plane, and the split of the index-2 table into a BMP
- * part and a supplementary part, with a gap in between, would not work.
- *
- * Requires UTRIE2_INDEX_SHIFT>=1 not because of the code but because
- * there is data with more than 64k distinct values,
- * for example for Unihan collation with a separate collation weight per
- * Han character.

-/**
- * <p>Ultralightweight C++ implementation of a <tt>void*</tt> vector
- * that is (mostly) compatible with java.util.Vector.
- *
- * <p>This is a very simple implementation, written to satisfy an
- * immediate porting need.  As such, it is not completely fleshed out,
- * and it aims for simplicity and conformity.  Nonetheless, it serves
- * its purpose (porting code from java that uses java.util.Vector)
- * well, and it could be easily made into a more robust vector class.
- *
- * <p><b>Design notes</b>
- *
- * <p>There is index bounds checking, but little is done about it.  If
- * indices are out of bounds, either nothing happens, or zero is
- * returned.  We <em>do</em> avoid indexing off into the weeds.
- *
- * <p>There is detection of out of memory, but the handling is very
- * coarse-grained -- similar to UnicodeString's protocol, but even
- * coarser.  The class contains <em>one static flag</em> that is set
- * when any call to <tt>new</tt> returns zero.  This allows the caller
- * to use several vectors and make just one check at the end to see if
- * a memory failure occurred.  This is more efficient than making a
- * check after each call on each vector when doing many operations on
- * multiple vectors.  The single static flag works best when memory
- * failures are infrequent, and when recovery options are limited or
- * nonexistent.
- *
- * <p>Since we don't have garbage collection, UVector was given the
- * option to <em>own</em>its contents.  To employ this, set a deleter
- * function.  The deleter is called on a void* pointer when that
- * pointer is released by the vector, either when the vector itself is
- * destructed, or when a call to setElementAt() overwrites an element,
- * or when a call to remove() or one of its variants explicitly
- * removes an element.  If no deleter is set, or the deleter is set to
- * zero, then it is assumed that the caller will delete elements as
- * needed.
- *
- * <p>In order to implement methods such as contains() and indexOf(),
- * UVector needs a way to compare objects for equality.  To do so, it
- * uses a comparison function, or "comparer."  If the comparer is not
- * set, or is set to zero, then all such methods will act as if the
- * vector contains no element.  That is, indexOf() will always return
- * -1, contains() will always return FALSE, etc.
- *
- * <p><b>To do</b>
- *
- * <p>Improve the handling of index out of bounds errors.

-/**
- * <p>Ultralightweight C++ implementation of a <tt>void*</tt> vector
- * that is (mostly) compatible with java.util.Vector.
- *
- * <p>This is a very simple implementation, written to satisfy an
- * immediate porting need.  As such, it is not completely fleshed out,
- * and it aims for simplicity and conformity.  Nonetheless, it serves
- * its purpose (porting code from java that uses java.util.Vector)
- * well, and it could be easily made into a more robust vector class.
- *
- * <p><b>Design notes</b>
- *
- * <p>There is index bounds checking, but little is done about it.  If
- * indices are out of bounds, either nothing happens, or zero is
- * returned.  We <em>do</em> avoid indexing off into the weeds.
- *
- * <p>There is detection of out of memory, but the handling is very
- * coarse-grained -- similar to UnicodeString's protocol, but even
- * coarser.  The class contains <em>one static flag</em> that is set
- * when any call to <tt>new</tt> returns zero.  This allows the caller
- * to use several vectors and make just one check at the end to see if
- * a memory failure occurred.  This is more efficient than making a
- * check after each call on each vector when doing many operations on
- * multiple vectors.  The single static flag works best when memory
- * failures are infrequent, and when recovery options are limited or
- * nonexistent.
- *
- * <p><b>To do</b>
- *
- * <p>Improve the handling of index out of bounds errors.

-/**
- * <p>Ultralightweight C++ implementation of an <tt>int64_t</tt> vector
- * that has a subset of methods from UVector32
- *
- * <p>This is a very simple implementation, written to satisfy an
- * immediate porting need.  As such, it is not completely fleshed out,
- * and it aims for simplicity and conformity.  Nonetheless, it serves
- * its purpose (porting code from java that uses java.util.Vector)
- * well, and it could be easily made into a more robust vector class.
- *
- * <p><b>Design notes</b>
- *
- * <p>There is index bounds checking, but little is done about it.  If
- * indices are out of bounds, either nothing happens, or zero is
- * returned.  We <em>do</em> avoid indexing off into the weeds.
- *
- * <p>There is detection of out of memory, but the handling is very
- * coarse-grained -- similar to UnicodeString's protocol, but even
- * coarser.  The class contains <em>one static flag</em> that is set
- * when any call to <tt>new</tt> returns zero.  This allows the caller
- * to use several vectors and make just one check at the end to see if
- * a memory failure occurred.  This is more efficient than making a
- * check after each call on each vector when doing many operations on
- * multiple vectors.  The single static flag works best when memory
- * failures are infrequent, and when recovery options are limited or
- * nonexistent.
- *
- * <p><b>To do</b>
- *
- * <p>Improve the handling of index out of bounds errors.

-//        //    ----------------------------
-//        //
-//        // To compute when an object rises or sets, you must compute when it
-//        // passes the meridian and the HA of rise/set.  Then the rise time is
-//        // the meridian time minus HA for rise/set, and the set time is the
-//        // meridian time plus the HA for rise/set.
-//        //
-//        // To find the meridian time, compute the Local Sidereal Time at 0h local
-//        // time (or 0h UT if you prefer to work in UT) as outlined above---name

-//        //

-//        double MT = normalize(sRA - LST, 360);
-//        //

-//        // add 360 deg to MT.  If the object is the Sun, leave the time as it is,
-//        // but if it's stellar, multiply MT by 365.2422/366.2422, to convert from
-//        // sidereal to solar time.  Now, compute HA for rise/set, name that
-//        // quantity HA0:
-//        //
-//        //                 ::sin(h0)  -  ::sin(lat) * ::sin(Dec)

-//        //
-//        //    cos(HA0)  =  - tan(lat) * tan(Dec)
-//        //
-//        // If you want to account for refraction on the atmosphere, set h0 = -35/60
-//        // degrees (-35 arc minutes), and if you want to compute the rise/set times
-//        // for the Sun's upper limb, set h0 = -50/60 (-50 arc minutes).

-//          (sin(h0) - ::sin(fLatitude) * sin_sDec) /
-//          (cos(fLatitude) * cos(sDec*DEG_RAD)))*RAD_DEG;
-//
-//        // When HA0 has been computed, leave it as it is for the Sun but multiply
-//        // by 365.2422/366.2422 for stellar objects, to convert from sidereal to
-//        // solar time.  Finally compute:
-//        //

-//        //    Set  time  =  MT + HA0
-//        //

-/**
- * <code>CalendarAstronomer</code> is a class that can perform the calculations to
- * determine the positions of the sun and moon, the time of sunrise and
- * sunset, and other astronomy-related data.  The calculations it performs
- * are in some cases quite complicated, and this utility class saves you
- * the trouble of worrying about them.
- * <p>
- * The measurement of time is a very important part of astronomy.  Because
- * astronomical bodies are constantly in motion, observations are only valid
- * at a given moment in time.  Accordingly, each <code>CalendarAstronomer</code>
- * object has a <code>time</code> property that determines the date
- * and time for which its calculations are performed.  You can set and
- * retrieve this property with {@link #setDate setDate}, {@link #getDate getDate}
- * and related methods.
- * <p>
- * Almost all of the calculations performed by this class, or by any
- * astronomer, are approximations to various degrees of accuracy.  The
- * calculations in this class are mostly modelled after those described
- * in the book
- * <a href="http://www.amazon.com/exec/obidos/ISBN=0521356997" target="_top">
- * Practical Astronomy With Your Calculator</a>, by Peter J.
- * Duffett-Smith, Cambridge University Press, 1990.  This is an excellent
- * book, and if you want a greater understanding of how these calculations
- * are performed it a very good, readable starting point.
- * <p>
- * <strong>WARNING:</strong> This class is very early in its development, and
- * it is highly likely that its API will change to some degree in the future.
- * At the moment, it basically does just enough to support {@link IslamicCalendar}
- * and {@link ChineseCalendar}.

- * "BOCSU"
- * Binary Ordered Compression Scheme for Unicode
- *
- * Specific application:
- *
- * Encode a Unicode string for the identical level of a sort key.
- * Restrictions:
- * - byte stream (unsigned 8-bit bytes)
- * - lexical order of the identical-level run must be
- *   the same as code point order for the string
- * - avoid byte values 0, 1, 2
- *
- * Method: Slope Detection
- * Remember the previous code point (initial 0).
- * For each cp in the string, encode the difference to the previous one.
- *
- * With a compact encoding of differences, this yields good results for
- * small scripts and UTF-like results otherwise.
- *
- * Encoding of differences:
- * - Similar to a UTF, encoding the length of the byte sequence in the lead bytes.
- * - Does not need to be friendly for decoding or random access
- *   (trail byte values may overlap with lead/single byte values).
- * - The signedness must be encoded as the most significant part.
- *
- * We encode differences with few bytes if their absolute values are small.
- * For correct ordering, we must treat the entire value range -10ffff..+10ffff
- * in ascending order, which forbids encoding the sign and the absolute value separately.
- * Instead, we split the lead byte range in the middle and encode non-negative values
- * going up and negative values going down.
- *
- * For very small absolute values, the difference is added to a middle byte value
- * for single-byte encoded differences.
- * For somewhat larger absolute values, the difference is divided by the number
- * of byte values available, the modulo is used for one trail byte, and the remainder
- * is added to a lead byte avoiding the single-byte range.
- * For large absolute values, the difference is similarly encoded in three bytes.
- *
- * This encoding does not use byte values 0, 1, 2, but uses all other byte values
- * for lead/single bytes so that the middle range of single bytes is as large
- * as possible.
- * Note that the lead byte ranges overlap some, but that the sequences as a whole
- * are well ordered. I.e., even if the lead byte is the same for sequences of different
- * lengths, the trail bytes establish correct order.
- * It would be possible to encode slightly larger ranges for each length (>1) by
- * subtracting the lower bound of the range. However, that would also slow down the
- * calculation.
- *
- * For the actual string encoding, an optimization moves the previous code point value
- * to the middle of its Unicode script block to minimize the differences in
- * same-script text runs.

- * 2*3=6    for 3-byte values
- * 2*1=2    for 4-byte values
- *
- * The sum must be <=SLOPE_TAIL_COUNT.
- *
- * Why these numbers?
- * - There should be >=128 single-byte values to cover 128-blocks
- *   with small scripts.
- * - There should be >=20902 single/double-byte values to cover Unihan.
- * - It helps CJK Extension B some if there are 3-byte values that cover
- *   the distance between them and Unihan.
- *   This also helps to jump among distant places in the BMP.
- * - Four-byte values are necessary to cover the rest of Unicode.

-// Data flow in Calendar
-// ---------------------
-
-// The current time is represented in two ways by Calendar: as UTC
-// milliseconds from the epoch start (1 January 1970 0:00 UTC), and as local
-// fields such as MONTH, HOUR, AM_PM, etc.  It is possible to compute the
-// millis from the fields, and vice versa.  The data needed to do this
-// conversion is encapsulated by a TimeZone object owned by the Calendar.
-// The data provided by the TimeZone object may also be overridden if the
-// user sets the ZONE_OFFSET and/or DST_OFFSET fields directly. The class
-// keeps track of what information was most recently set by the caller, and
-// uses that to compute any other information as needed.
-
-// If the user sets the fields using set(), the data flow is as follows.
-// This is implemented by the Calendar subclass's computeTime() method.
-// During this process, certain fields may be ignored.  The disambiguation
-// algorithm for resolving which fields to pay attention to is described
-// above.
-
-//   local fields (YEAR, MONTH, DATE, HOUR, MINUTE, etc.)
-//           |
-//           | Using Calendar-specific algorithm
-//           V
-//   local standard millis
-//           |
-//           | Using TimeZone or user-set ZONE_OFFSET / DST_OFFSET
-//           V
-//   UTC millis (in time data member)
-
-// If the user sets the UTC millis using setTime(), the data flow is as
-// follows.  This is implemented by the Calendar subclass's computeFields()
-// method.
-
-//   UTC millis (in time data member)
-//           |
-//           | Using TimeZone getOffset()
-//           V
-//   local standard millis
-//           |
-//           | Using Calendar-specific algorithm
-//           V
-//   local fields (YEAR, MONTH, DATE, HOUR, MINUTE, etc.)
-
-// In general, a round trip from fields, through local and UTC millis, and
-// back out to fields is made when necessary.  This is implemented by the
-// complete() method.  Resolving a partial set of fields into a UTC millis
-// value allows all remaining fields to be generated from that value.  If
-// the Calendar is lenient, the fields are also renormalized to standard
-// ranges when they are regenerated.

-/**
-* Prepare this calendar for computing the actual minimum or maximum.
-* This method modifies this calendar's fields; it is called on a

-*
-* <p>Rationale: The semantics of getActualXxx() is to return the
-* maximum or minimum value that the given field can take, taking into
-* account other relevant fields.  In general these other fields are
-* larger fields.  For example, when computing the actual maximum
-* DATE, the current value of DATE itself is ignored,
-* as is the value of any field smaller.
-*
-* <p>The time fields all have fixed minima and maxima, so we don't
-* need to worry about them.  This also lets us set the
-* MILLISECONDS_IN_DAY to zero to erase any effects the time fields
-* might have when computing date fields.
-*
-* <p>DAY_OF_WEEK is adjusted specially for the WEEK_OF_MONTH and
-* WEEK_OF_YEAR fields to ensure that they are computed correctly.

-/**
- * <code>ChineseCalendar</code> is a concrete subclass of {@link Calendar}
- * that implements a traditional Chinese calendar.  The traditional Chinese
- * calendar is a lunisolar calendar: Each month starts on a new moon, and
- * the months are numbered according to solar events, specifically, to
- * guarantee that month 11 always contains the winter solstice.  In order
- * to accomplish this, leap months are inserted in certain years.  Leap
- * months are numbered the same as the month they follow.  The decision of
- * which month is a leap month depends on the relative movements of the sun
- * and moon.
- *
- * <p>This class defines one addition field beyond those defined by
- * <code>Calendar</code>: The <code>IS_LEAP_MONTH</code> field takes the
- * value of 0 for normal months, or 1 for leap months.
- *
- * <p>All astronomical computations are performed with respect to a time
- * zone of GMT+8:00 and a longitude of 120 degrees east.  Although some
- * calendars implement a historically more accurate convention of using
- * Beijing's local longitude (116 degrees 25 minutes east) and time zone
- * (GMT+7:45:40) for dates before 1929, we do not implement this here.
- *
- * <p>Years are counted in two different ways in the Chinese calendar.  The
- * first method is by sequential numbering from the 61st year of the reign
- * of Huang Di, 2637 BCE, which is designated year 1 on the Chinese
- * calendar.  The second method uses 60-year cycles from the same starting
- * point, which is designated year 1 of cycle 1.  In this class, the
- * <code>EXTENDED_YEAR</code> field contains the sequential year count.
- * The <code>ERA</code> field contains the cycle number, and the
- * <code>YEAR</code> field contains the year of the cycle, a value between
- * 1 and 60.
- *
- * <p>There is some variation in what is considered the starting point of
- * the calendar, with some sources starting in the first year of the reign
- * of Huang Di, rather than the 61st.  This gives continuous year numbers
- * 60 years greater and cycle numbers one greater than what this class
- * implements.
- *
- * <p>Because <code>ChineseCalendar</code> defines an additional field and
- * redefines the way the <code>ERA</code> field is used, it requires a new
- * format class, <code>ChineseDateFormat</code>.  As always, use the
- * methods <code>DateFormat.getXxxInstance(Calendar cal,...)</code> to
- * obtain a formatter for this calendar.

-/**
- * File coll.cpp
- *
- * Created by: Helena Shih
- *
- * Modification History:
- *
- *  Date        Name        Description
- *  2/5/97      aliu        Modified createDefault to load collation data from
- *                          binary files when possible.  Added related methods
- *                          createCollationFromFile, chopLocale, createPathName.
- *  2/11/97     aliu        Added methods addToCache, findInCache, which implement
- *                          a Collation cache.  Modified createDefault to look in
- *                          cache first, and also to store newly created Collation
- *                          objects in the cache.  Modified to not use gLocPath.
- *  2/12/97     aliu        Modified to create objects from RuleBasedCollator cache.
- *                          Moved cache out of Collation class.
- *  2/13/97     aliu        Moved several methods out of this class and into
- *                          RuleBasedCollator, with modifications.  Modified
- *                          createDefault() to call new RuleBasedCollator(Locale&)
- *                          constructor.  General clean up and documentation.
- *  2/20/97     helena      Added clone, operator==, operator!=, operator=, and copy
- *                          constructor.
- * 05/06/97     helena      Added memory allocation error detection.
- * 05/08/97     helena      Added createInstance().
- *  6/20/97     helena      Java class name change.
- * 04/23/99     stephen     Removed EDecompositionMode, merged with 
- *                          Normalizer::EMode
- * 11/23/9      srl         Inlining of some critical functions
- * 01/29/01     synwee      Modified into a C++ wrapper calling C APIs (ucol.h)
- * 2012-2014    markus      Rewritten in C++ again.

-     * which point to stable indexes in this list,
-     * and temporary CEs stored in a CollationDataBuilder only point to tailored nodes.
-     *
-     * A temporary CE in the ces[] array may point to a non-tailored reset-before-position node,
-     * until the next relation is added.
-     *
-     * At the end, the tailored weights are allocated as necessary,

-     * We cannot simply insert new nodes in the middle of the array
-     * because that would invalidate the indexes stored in existing temporary CEs.
-     * We need to use a linked graph with stable indexes to existing nodes.
-     * A doubly-linked list seems easiest to maintain.
-     *
-     * Each node is stored as an int64_t, with its fields stored as bit fields.
-     *
-     * Root primary node:
-     * - primary weight: 32 bits 63..32
-     * - reserved/unused/zero: 4 bits 31..28
-     *
-     * Weaker root nodes & tailored nodes:
-     * - a weight: 16 bits 63..48
-     *   + a root or default weight for a non-tailored node
-     *   + unused/zero for a tailored node
-     * - index to the previous node: 20 bits 47..28
-     *
-     * All types of nodes:
-     * - index to the next node: 20 bits 27..8
-     *   + nextIndex=0 in last node per root-primary list
-     * - reserved/unused/zero bits: bits 7, 4, 2
-     * - HAS_BEFORE2: bit 6
-     * - HAS_BEFORE3: bit 5
-     * - IS_TAILORED: bit 3
-     * - the difference strength (primary/secondary/tertiary/quaternary): 2 bits 1..0
-     *
-     * We could allocate structs with pointers, but we would have to store them
-     * in a pointer list so that they can be indexed from temporary CEs,
-     * and they would require more memory allocations.

-/*
- * Format of collation data (ucadata.icu, binary data in coll/ *.res files).
- * Format version 5.
- *
- * The root collation data is stored in the ucadata.icu file.
- * Tailorings are stored inside .res resource bundle files, with a complete file header.
- *
- * Collation data begins with a standard ICU data file header
- * (DataHeader, see ucmndata.h and unicode/udata.h).
- * The UDataInfo.dataVersion field contains the UCA and other version numbers,
- * see the comments for CollationTailoring.version.
- *
- * After the header, the file contains the following parts.
- * Constants are defined as enum values of the CollationDataReader class.
- * See also the Collation class.
- *
- * int32_t indexes[indexesLength];
- *      The indexes array has variable length.
- *      Some tailorings only need the length and the options,
- *      others only add reorderCodes and the reorderTable,
- *      some need to store mappings.
- *      Only as many indexes are stored as needed to read all of the data.
- *
- *      Index 0: indexesLength
- *      Index 1: numericPrimary, CollationFastLatin::VERSION, and options: see IX_OPTIONS
- *      Index 2..3: Unused/reserved/0.
- *      Index 4: Index into the ce32s array where the CE32s of the conjoining Jamo
- *               are stored in a short, contiguous part of the ce32s array.
- *
- *      Indexes 5..19 are byte offsets in ascending order.
- *      Each byte offset marks the start of the next part in the data file,
- *      and the end of the previous one.
- *      When two consecutive byte offsets are the same (or too short),
- *      then the corresponding part is empty.
- *      Byte offsets are offsets from after the header,
- *      that is, from the beginning of the indexes[].
- *      Each part starts at an offset with proper alignment for its data.
- *      If necessary, the previous part may include padding bytes to achieve this alignment.
- *      The last byte offset that is stored in the indexes indicates the total size of the data
- *      (starting with the indexes).
- *
- * int32_t reorderCodes[]; -- empty in root
- *      The list of script and reordering codes.
- *
- *      Beginning with format version 5, this array may optionally
- *      have trailing entries with a full list of reorder ranges
- *      as described for CollationSettings::reorderRanges.
- *
- *      Script or reorder codes are first and do not exceed 16-bit values.
- *      Range limits are stored in the upper 16 bits, and are never 0.
- *      Split this array into reorder codes and ranges at the first entry
- *      with non-zero upper 16 bits.
- *
- *      If the ranges are missing but needed for split-reordered primary lead bytes,
- *      then they are regenerated at load time.
- *
- * uint8_t reorderTable[256]; -- empty in root; can be longer to include padding bytes
- *      Primary-weight lead byte permutation table.
- *      Normally present when the reorderCodes are, but can be built at load time.
- *
- *      Beginning with format version 5, a 0 entry at a non-zero index
- *      (which is otherwise an illegal value)
- *      means that the primary lead byte is "split"
- *      (there are different offsets for primaries that share that lead byte)
- *      and the reordering offset must be determined via the reorder ranges
- *      that are either stored as part of the reorderCodes array
- *      or regenerated at load time.
- *
- * UTrie2 trie; -- see utrie2_impl.h and utrie2.h
- *      The trie holds the main collation data. Each code point is mapped to a 32-bit value.
- *      It encodes a simple collation element (CE) in compact form, unless bits 7..6 are both set,
- *      in which case it is a special CE32 and contains a 4-bit tag and further data.
- *      See the Collation class for details.
- *
- *      The trie has a value for each lead surrogate code unit with some bits encoding
- *      collective properties of the 1024 supplementary characters whose UTF-16 form starts with
- *      the lead surrogate. See Collation::LEAD_SURROGATE_TAG..
- *
- * int64_t ces[];
- *      64-bit CEs and expansions that cannot be stored in a more compact form.
- *
- * uint32_t ce32s[];
- *      CE32s for expansions in compact form, and for characters whose trie values
- *      contain special data.
- *
- * uint32_t rootElements[]; -- empty in all tailorings
- *      Compact storage for all of the CEs that occur in the root collation.
- *      See the CollationRootElements class.
- *
- * UChar *contexts[];
- *      Serialized UCharsTrie structures with prefix (pre-context) and contraction mappings.
- *
- * uint16_t unsafeBackwardSet[]; -- see UnicodeSet::serialize()
- *      Serialized form of characters that are unsafe when iterating backwards,
- *      and at the end of an identical string prefix.
- *      Back up to a safe character.
- *      Lead surrogates are "unsafe" when any of their corresponding supplementary
- *      code points are unsafe.
- *      Does not include [:^lccc=0:][:^tccc=0:].
- *      For each tailoring, the root unsafeBackwardSet is subtracted.
- *      (As a result, in many tailorings no set needs to be stored.)
- *
- * uint16_t fastLatinTable[];
- *      Optional optimization for Latin text.
- *      See the CollationFastLatin class.
- *
- * uint16_t scripts[]; -- empty in all tailorings
- *      Format version 5:
- *      uint16_t numScripts;
- *      uint16_t scriptsIndex[numScripts+16];
- *      uint16_t scriptStarts[];
- *      See CollationData::numScripts etc.
- *
- *      Format version 4:
- *      Table of the reordering groups with their first and last lead bytes,
- *      and their script and reordering codes.
- *      See CollationData::scripts.
- *
- * UBool compressibleBytes[]; -- empty in all tailorings
- *      Flag for getSortKey(), indicating primary weight lead bytes that are compressible.
- *
- * -----------------
- * Changes for formatVersion 5 (ICU 55)
- *
- * Reordering moves single scripts, not groups of scripts.
- * Reorder ranges are optionally appended to the reorderCodes,
- * and a 0 entry in the reorderTable indicates a split lead byte.
- * The scripts data has a new format.
- *
- * The rootElements may contain secondary and tertiary weights below common=05.
- * (Used for small Hiragana letters.)
- * Where is occurs, there is also an explicit unit with common secondary & tertiary weights.
- * There are no other data structure changes, but builder code needs to be able to handle such data.
- *
- * The collation element for the merge separator code point U+FFFE
- * does not necessarily have special, unique secondary/tertiary weights any more.

-/*
- * Format of the CollationFastLatin data table.
- * CollationFastLatin::VERSION = 2.
- *
- * This table contains data for a Latin-text collation fastpath.
- * The data is stored as an array of uint16_t which contains the following parts.
- *
- * uint16_t  -- version & header length
- *   Bits 15..8: version, must match the VERSION
- *         7..0: length of the header
- *
- * uint16_t varTops[header length - 1]
- *   Version 2:
- *   varTops[m] is the highest CollationFastLatin long-primary weight
- *   of supported maxVariable group m
- *   (special reorder group space, punct, symbol, currency).
- *
- *   Version 1:
- *   Each of these values maps the variable top lead byte of a supported maxVariable group
- *   to the highest CollationFastLatin long-primary weight.
- *   The values are stored in ascending order.
- *   Bits 15..7: max fast-Latin long-primary weight (bits 11..3 shifted left by 4 bits)
- *         6..0: regular primary lead byte
- *
- * uint16_t miniCEs[0x1c0]
- *   A mini collation element for each character U+0000..U+017F and U+2000..U+203F.
- *   Each value encodes one or two mini CEs (two are possible if the first one
- *   has a short mini primary and the second one is a secondary CE, i.e., primary == 0),
- *   or points to an expansion or to a contraction table.
- *   U+0000 always has a contraction entry,
- *   so that NUL-termination need not be tested in the fastpath.
- *   If the collation elements for a character or contraction cannot be encoded in this format,
- *   then the BAIL_OUT value is stored.
- *   For details see the comments for the class constants.
- *
- * uint16_t expansions[variable length];
- *   Expansion mini CEs contain an offset relative to just after the miniCEs table.
- *   An expansions contains exactly 2 mini CEs.
- *
- * uint16_t contractions[variable length];
- *   Contraction mini CEs contain an offset relative to just after the miniCEs table.
- *   It points to a list of tuples which map from a contraction suffix character to a result.
- *   First uint16_t of each tuple:
- *     Bits 10..9: Length of the result (1..3), see comments on CONTR_LENGTH_SHIFT.
- *     Bits  8..0: Contraction character, see comments on CONTR_CHAR_MASK.
- *   This is followed by 0, 1, or 2 uint16_t according to the length.
- *   Each list is terminated by an entry with CONTR_CHAR_MASK.
- *   Each list starts with such an entry which also contains the default result
- *   for when there is no contraction match.
- *
- * -----------------
- * Changes for version 2 (ICU 55)
- *
- * Special reorder groups do not necessarily start on whole primary lead bytes any more.
- * Therefore, the varTops data has a new format:
- * Version 1 stored the lead bytes of the highest root primaries for
- * the maxVariable-supported special reorder groups.
- * Now the top 16 bits would need to be stored,
- * and it is simpler to store only the fast-Latin weights.

-/**
- * Data and functions for the FCD check fast path.
- *
- * The fast path looks at a pair of 16-bit code units and checks
- * whether there is an FCD boundary between them;
- * there is if the first unit has a trailing ccc=0 (!hasTccc(first))
- * or the second unit has a leading ccc=0 (!hasLccc(second)),
- * or both.
- * When the fast path finds a possible non-boundary,
- * then the FCD check slow path looks at the actual sequence of FCD values.
- *
- * This is a pure optimization.
- * The fast path must at least find all possible non-boundaries.
- * If the fast path is too pessimistic, it costs performance.
- *
- * For a pair of BMP characters, the fast path tests are precise (1 bit per character).
- *
- * For a supplementary code point, the two units are its lead and trail surrogates.
- * We set hasTccc(lead)=true if any of its 1024 associated supplementary code points
- * has lccc!=0 or tccc!=0.
- * We set hasLccc(trail)=true for all trail surrogates.
- * As a result, we leave the fast path if the lead surrogate might start a
- * supplementary code point that is not FCD-inert.
- * (So the fast path need not detect that there is a surrogate pair,
- * nor look ahead to the next full code point.)
- *
- * hasLccc(lead)=true if any of its 1024 associated supplementary code points
- * has lccc!=0, for fast boundary checking between BMP & supplementary.
- *
- * hasTccc(trail)=false:
- * It should only be tested for unpaired trail surrogates which are FCD-inert.

-/* 5. Rounding is deferred until finalization of results, with any    */
-/*    'off to the right' data being represented as a single digit     */
-/*    residue (in the range -1 through 9).  This avoids any double-   */

-//   Example: toFixed(0.001, 5) is allowed to return buffer="1", point=-2.

-//   of its digits. That is, just because it contains '0's does not mean that
-//   any other digit would not satisfy the internal identity requirement.
-//  - PRECISION: produces 'requested_digits' where the first digit is not '0'.
-//   Even though the length of produced digits usually equals
-//   'requested_digits', the function is allowed to return fewer digits, in
-//   which case the caller has to fill the missing digits with '0's.

-  //      With this flag "0x" is a junk-string. Even with ALLOW_TRAILING_JUNK,
-  //      the string will not be parsed as "0" followed by junk.
-  //
-  //  - ALLOW_OCTALS: recognizes the prefix "0" for octals:
-  //      If a sequence of octal digits starts with '0', then the number is
-  //      read as octal integer. Octal numbers may only be integers.
-  //      Ex: StringToDouble("01234") -> 668.0

-  //          In StringToDouble("01234e56") the characters "e56" are trailing
-  //          junk, too.
-  //  - ALLOW_TRAILING_JUNK: ignore trailing characters that are not part of
-  //      a double literal.
-  //  - ALLOW_LEADING_SPACES: skip over leading whitespace, including spaces,
-  //                          new-lines, and tabs.
-  //  - ALLOW_TRAILING_SPACES: ignore trailing whitespace.
-  //  - ALLOW_SPACES_AFTER_SIGN: ignore whitespace after the sign.
-  //       Ex: StringToDouble("-   123.2") -> -123.2.
-  //           StringToDouble("+   123.2") -> 123.2
-  //  - ALLOW_CASE_INSENSITIVITY: ignore case of characters for special values:
-  //      infinity and nan.
-  //  - ALLOW_HEX_FLOATS: allows hexadecimal float literals.
-  //      This *must* start with "0x" and separate the exponent with "p".
-  //      Examples: 0x1.2p3 == 9.0
-  //                0x10.1p0 == 16.0625
-  //      ALLOW_HEX and ALLOW_HEX_FLOATS are indendent.
-  //
-  // empty_string_value is returned when an empty string is given as input.
-  // If ALLOW_LEADING_SPACES or ALLOW_TRAILING_SPACES are set, then a string
-  // containing only spaces is converted to the 'empty_string_value', too.
-  //
-  // junk_string_value is returned when
-  //  a) ALLOW_TRAILING_JUNK is not set, and a junk character (a character not
-  //     part of a double-literal) is found.
-  //  b) ALLOW_TRAILING_JUNK is set, but the string does not start with a
-  //     double literal.
-  //
-  // infinity_symbol and nan_symbol are strings that are used to detect
-  // inputs that represent infinity and NaN. They can be null, in which case
-  // they are ignored.
-  // The conversion routine first reads any possible signs. Then it compares the
-  // following character of the input-string with the first character of
-  // the infinity, and nan-symbol. If either matches, the function assumes, that
-  // a match has been found, and expects the following input characters to match
-  // the remaining characters of the special-value symbol.
-  // This means that the following restrictions apply to special-value symbols:
-  //  - they must not start with signs ('+', or '-'),
-  //  - they must not have the same first character.
-  //  - they must not start with digits.
-  //
-  // If the separator character is not kNoSeparator, then that specific
-  // character is ignored when in between two valid digits of the significant.
-  // It is not allowed to appear in the exponent.
-  // It is not allowed to lead or trail the number.
-  // It is not allowed to appear twice next to each other.
-  //
-  // Examples:
-  //  flags = ALLOW_HEX | ALLOW_TRAILING_JUNK,
-  //  empty_string_value = 0.0,
-  //  junk_string_value = NaN,
-  //  infinity_symbol = "infinity",
-  //  nan_symbol = "nan":
-  //    StringToDouble("0x1234") -> 4660.0.
-  //    StringToDouble("0x1234K") -> 4660.0.
-  //    StringToDouble("") -> 0.0  // empty_string_value.

-// The type-based aliasing rule allows the compiler to assume that pointers of
-// different types (for some definition of different) never alias each other.
-// Thus the following code does not work:
-//
-// float f = foo();
-// int fbits = *(int*)(&f);
-//
-// The compiler 'knows' that the int pointer can't refer to f since the types
-// don't match, so the compiler may cache f in a register, leaving random data
-// in fbits.  Using C++ style casts makes no difference, however a pointer to
-// char data is assumed to alias any other pointer.  This is the 'memcpy
-// exception'.
-//
-// Bit_cast uses the memcpy exception to move the bits from a variable of one
-// type of a variable of another type.  Of course the end result is likely to
-// be implementation dependent.  Most compilers (gcc-4.2 and MSVC 2005)
-// will completely optimize BitCast away.
-//
-// There is an additional use for BitCast.
-// Recent gccs will warn when they see casts that may result in breakage due to
-// the type-based aliasing rule.  If you have checked that there is no breakage
-// you can use BitCast to cast one pointer type to another.  This confuses gcc
-// enough that it can no longer see that you have cast one pointer type to
-// another thus avoiding the warning.

-/**
- * Initialize interval patterns locale to this formatter
- *
- * This code is a bit complicated since
- * 1. the interval patterns saved in resource bundle files are interval
- *    patterns based on date or time only.
- *    It does not have interval patterns based on both date and time.
- *    Interval patterns on both date and time are algorithm generated.
- *
- *    For example, it has interval patterns on skeleton "dMy" and "hm",
- *    but it does not have interval patterns on skeleton "dMyhm".
- *
- *    The rule to genearte interval patterns for both date and time skeleton are
- *    1) when the year, month, or day differs, concatenate the two original
- *    expressions with a separator between,
- *    For example, interval pattern from "Jan 10, 2007 10:10 am"
- *    to "Jan 11, 2007 10:10am" is
- *    "Jan 10, 2007 10:10 am - Jan 11, 2007 10:10am"
- *
- *    2) otherwise, present the date followed by the range expression
- *    for the time.
- *    For example, interval pattern from "Jan 10, 2007 10:10 am"
- *    to "Jan 10, 2007 11:10am" is
- *    "Jan 10, 2007 10:10 am - 11:10am"
- *
- * 2. even a pattern does not request a certion calendar field,
- *    the interval pattern needs to include such field if such fields are
- *    different between 2 dates.
- *    For example, a pattern/skeleton is "hm", but the interval pattern
- *    includes year, month, and date when year, month, and date differs.

- * A transliterator that converts Unicode characters to an escape

- * Escape forms have a prefix and suffix, either of which may be
- * empty, a radix, typically 16 or 10, a minimum digit count,
- * typically 1, 4, or 8, and a boolean that specifies whether
- * supplemental characters are handled as 32-bit code points or as two
- * 16-bit code units.  Most escape forms handle 32-bit code points,

- * surrogate pairs, for backward compatibility.
- *
- * <p>Some escape forms actually have two different patterns, one for
- * BMP characters (0..FFFF) and one for supplements (>FFFF).  To
- * handle this, a second EscapeTransliterator may be defined that
- * specifies the pattern to be produced for supplementals.  An example
- * of a form that requires this is the C form, which uses "\\uFFFF"
- * for BMP characters and "\\U0010FFFF" for supplementals.

-*   02/05/97    clhuang     Creation.
-*   03/28/97    aliu        Made highly questionable fix to computeFields to
-*                           handle DST correctly.
-*   04/22/97    aliu        Cleaned up code drastically.  Added monthLength().
-*                           Finished unimplemented parts of computeTime() for
-*                           week-based date determination.  Removed quetionable
-*                           fix and wrote correct fix for computeFields() and
-*                           daylight time handling.  Rewrote inDaylightTime()
-*                           and computeFields() to handle sensitive Daylight to
-*                           Standard time transitions correctly.
-*   05/08/97    aliu        Added code review changes.  Fixed isLeapYear() to
-*                           not cutover.
-*   08/12/97    aliu        Added equivalentTo.  Misc other fixes.  Updated
-*                           add() from Java source.
-*    07/28/98    stephen        Sync up with JDK 1.2
-*    09/14/98    stephen        Changed type of kOneDay, kOneWeek to double.
-*                            Fixed bug in roll() 
-*   10/15/99    aliu        Fixed j31, incorrect WEEK_OF_YEAR computation.
-*   10/15/99    aliu        Fixed j32, cannot set date to Feb 29 2000 AD.
-*                           {JDK bug 4210209 4209272}
-*   11/15/99    weiv        Added YEAR_WOY and DOW_LOCAL computation
-*                           to timeToFields method, updated kMinValues, kMaxValues & kLeastMaxValues
-*   12/09/99    aliu        Fixed j81, calculation errors and roll bugs
-*                           in year of cutover.
-*   01/24/2000  aliu        Revised computeJulianDay for YEAR YEAR_WOY WOY.

-* Rolls (up/down) a specified amount time on the given field.  For
-* example, to roll the current date up by three days, you can call
-* <code>roll(Calendar.DATE, 3)</code>.  If the
-* field is rolled past its maximum allowable value, it will "wrap" back
-* to its minimum and continue rolling.  
-* For example, calling <code>roll(Calendar.DATE, 10)</code>
-* on a Hebrew calendar set to "25 Av 5758" will result in the date "5 Av 5758".
-* <p>
-* When rolling certain fields, the values of other fields may conflict and
-* need to be changed.  For example, when rolling the {@link #MONTH MONTH} field
-* upward by one for the date "30 Av 5758", the {@link #DAY_OF_MONTH DAY_OF_MONTH} field
-* must be adjusted so that the result is "29 Elul 5758" rather than the invalid
-* "30 Elul".
-* <p>
-* This method is able to roll
-* all fields except for {@link #ERA ERA}, {@link #DST_OFFSET DST_OFFSET},
-* and {@link #ZONE_OFFSET ZONE_OFFSET}.  Subclasses may, of course, add support for
-* additional fields in their overrides of <code>roll</code>.
-* <p>
-* <b>Note:</b> You should always use roll and {@link #add add} rather
-* than attempting to perform arithmetic operations directly on the fields
-* of a <tt>HebrewCalendar</tt>.  Since the {@link #MONTH MONTH} field behaves
-* discontinuously in non-leap years, simple arithmetic can give invalid results.
-* <p>
-* @param field     the time field.
-* @param amount    the amount by which the field should be rolled.

-/**
- * <code>HebrewCalendar</code> is a subclass of <code>Calendar</code>
- * that that implements the traditional Hebrew calendar.
- * This is the civil calendar in Israel and the liturgical calendar
- * of the Jewish faith worldwide.
- * <p>
- * The Hebrew calendar is lunisolar and thus has a number of interesting
- * properties that distinguish it from the Gregorian.  Months start
- * on the day of (an arithmetic approximation of) each new moon.  Since the
- * solar year (approximately 365.24 days) is not an even multiple of
- * the lunar month (approximately 29.53 days) an extra "leap month" is
- * inserted in 7 out of every 19 years.  To make matters even more
- * interesting, the start of a year can be delayed by up to three days
- * in order to prevent certain holidays from falling on the Sabbath and
- * to prevent certain illegal year lengths.  Finally, the lengths of certain
- * months can vary depending on the number of days in the year.
- * <p>
- * The leap month is known as "Adar 1" and is inserted between the
- * months of Shevat and Adar in leap years.  Since the leap month does
- * not come at the end of the year, calculations involving
- * month numbers are particularly complex.  Users of this class should
- * make sure to use the {@link #roll roll} and {@link #add add} methods
- * rather than attempting to perform date arithmetic by manipulating
- * the fields directly.
- * <p>
- * <b>Note:</b> In the traditional Hebrew calendar, days start at sunset.
- * However, in order to keep the time fields in this class
- * synchronized with those of the other calendars and with local clock time,
- * we treat days and months as beginning at midnight,
- * roughly 6 hours after the corresponding sunset.
- * <p>
- * If you are interested in more information on the rules behind the Hebrew
- * calendar, see one of the following references:

-/**
- * Concrete class which provides the Indian calendar.
- * <P>
- * <code>IndianCalendar</code> is a subclass of <code>Calendar</code>
- * that numbers years since the begining of SAKA ERA.  This is the civil calendar
- * which is accepted by government of India as Indian National Calendar.
- * The two calendars most widely used in India today are the Vikrama calendar
- * followed in North India and the Shalivahana or Saka calendar which is followed
- * in South India and Maharashtra.
-
- * A variant of the Shalivahana Calendar was reformed and standardized as the
- * Indian National calendar in 1957.
- * <p>
- * Some details of Indian National Calendar (to be implemented) :
- * The Months
- * Month          Length      Start date (Gregorian)
- * =================================================
- * 1 Chaitra      30/31          March 22*
- * 2 Vaisakha     31             April 21
- * 3 Jyaistha     31             May 22
- * 4 Asadha       31             June 22
- * 5 Sravana      31             July 23
- * 6 Bhadra       31             August 23
- * 7 Asvina       30             September 23
- * 8 Kartika      30             October 23
- * 9 Agrahayana   30             November 22
- * 10 Pausa       30             December 22
- * 11 Magha       30             January 21
- * 12 Phalguna    30             February 20
-
- * In leap years, Chaitra has 31 days and starts on March 21 instead.
- * The leap years of Gregorian calendar and Indian National Calendar are in synchornization.
- * So When its a leap year in Gregorian calendar then Chaitra has 31 days.
- *
- * The Years
- * Years are counted in the Saka Era, which starts its year 0 in 78AD (by gregorian calendar).
- * So for eg. 9th June 2006 by Gregorian Calendar, is same as 19th of Jyaistha in 1928 of Saka
- * era by Indian National Calendar.
- * <p>
- * The Indian Calendar has only one allowable era: <code>Saka Era</code>.  If the
- * calendar is not in lenient mode (see <code>setLenient</code>), dates before
- * 1/1/1 Saka Era are rejected with an <code>IllegalArgumentException</code>.

-/**
- * <code>IslamicCalendar</code> is a subclass of <code>Calendar</code>
- * that implements the Islamic civil and religious calendars.  It
- * is used as the civil calendar in most of the Arab world and the
- * liturgical calendar of the Islamic faith worldwide.  This calendar
- * is also known as the "Hijri" calendar, since it starts at the time
- * of Mohammed's emigration (or "hijra") to Medinah on Thursday, 
- * July 15, 622 AD (Julian).
- * <p>
- * The Islamic calendar is strictly lunar, and thus an Islamic year of twelve
- * lunar months does not correspond to the solar year used by most other
- * calendar systems, including the Gregorian.  An Islamic year is, on average,
- * about 354 days long, so each successive Islamic year starts about 11 days
- * earlier in the corresponding Gregorian year.
- * <p>
- * Each month of the calendar starts when the new moon's crescent is visible
- * at sunset.  However, in order to keep the time fields in this class
- * synchronized with those of the other calendars and with local clock time,
- * we treat days and months as beginning at midnight,
- * roughly 6 hours after the corresponding sunset.
- * <p>
- * There are two main variants of the Islamic calendar in existence.  The first
- * is the <em>civil</em> calendar, which uses a fixed cycle of alternating 29-
- * and 30-day months, with a leap day added to the last month of 11 out of
- * every 30 years.  This calendar is easily calculated and thus predictable in
- * advance, so it is used as the civil calendar in a number of Arab countries.
- * This is the default behavior of a newly-created <code>IslamicCalendar</code>
- * object.
- * <p>
- * The Islamic <em>religious</em> calendar, however, is based on the <em>observation</em>
- * of the crescent moon.  It is thus affected by the position at which the
- * observations are made, seasonal variations in the time of sunset, the
- * eccentricities of the moon's orbit, and even the weather at the observation
- * site.  This makes it impossible to calculate in advance, and it causes the
- * start of a month in the religious calendar to differ from the civil calendar
- * by up to three days.
- * <p>
- * Using astronomical calculations for the position of the sun and moon, the
- * moon's illumination, and other factors, it is possible to determine the start
- * of a lunar month with a fairly high degree of certainty.  However, these
- * calculations are extremely complicated and thus slow, so most algorithms,
- * including the one used here, are only approximations of the true astronical
- * calculations.  At present, the approximations used in this class are fairly
- * simplistic; they will be improved in later versions of the code.
- * <p>
- * The {@link #setCivil setCivil} method determines
- * which approach is used to determine the start of a month.  By default, the
- * fixed-cycle civil calendar is used.  However, if <code>setCivil(false)</code>
- * is called, an approximation of the true lunar calendar will be used.

-/**
- * Concrete class which provides the Japanese calendar.
- * <P>
- * <code>JapaneseCalendar</code> is a subclass of <code>GregorianCalendar</code>
- * that numbers years and eras based on the reigns of the Japanese emperors.
- * The Japanese calendar is identical to the Gregorian calendar in all respects
- * except for the year and era.  The ascension of each  emperor to the throne
- * begins a new era, and the years of that era are numbered starting with the
- * year of ascension as year 1.
- * <p>
- * Note that in the year of an imperial ascension, there are two possible sets
- * of year and era values: that for the old era and for the new.  For example, a
- * new era began on January 7, 1989 AD.  Strictly speaking, the first six days
- * of that year were in the Showa era, e.g. "January 6, 64 Showa", while the rest
- * of the year was in the Heisei era, e.g. "January 7, 1 Heisei".  This class
- * handles this distinction correctly when computing dates.  However, in lenient
- * mode either form of date is acceptable as input. 
- * <p>
- * In modern times, eras have started on January 8, 1868 AD, Gregorian (Meiji),
- * July 30, 1912 (Taisho), December 25, 1926 (Showa), and January 7, 1989 (Heisei).  Constants
- * for these eras, suitable for use in the <code>UCAL_ERA</code> field, are provided
- * in this class.  Note that the <em>number</em> used for each era is more or
- * less arbitrary.  Currently, the era starting in 645 AD is era #0; however this
- * may change in the future.  Use the predefined constants rather than using actual,
- * absolute numbers.
- * <p>
- * Since ICU4C 63, start date of each era is imported from CLDR. CLDR era data
- * may contain tentative era in near future with placeholder names. By default,
- * such era data is not enabled. ICU4C users who want to test the behavior of
- * the future era can enable this one of following settings (in the priority
- * order):
- * <ol>
- * <li>Environment variable <code>ICU_ENABLE_TENTATIVE_ERA=true</code>.</li>

-     * guess the multiplier to be -3. However, then you end up getting 1000E3, which is not the correct output. You then
-     * change your multiplier to be -6, and you get 1.0E6, which is correct.
-     *
-     * @param input The quantity to process.
-     * @param producer Function to call to return a multiplier based on a magnitude.
-     * @return The number of orders of magnitude the input was adjusted by this method.

-/**
- * A time zone based on the Olson tz database.  Olson time zones change
- * behavior over time.  The raw offset, rules, presence or absence of
- * daylight savings time, and even the daylight savings amount can all
- * vary.
- *
- * This class uses a resource bundle named "zoneinfo".  Zoneinfo is a
- * table containing different kinds of resources.  In several places,
- * zones are referred to using integers.  A zone's integer is a number
- * from 0..n-1, where n is the number of zones, with the zones sorted
- * in lexicographic order.
- *
- * 1. Zones.  These have keys corresponding to the Olson IDs, e.g.,
- * "Asia/Shanghai".  Each resource describes the behavior of the given
- * zone.  Zones come in two different formats.
- *
- *   a. Zone (table).  A zone is a table resource contains several
- *   type of resources below:
- *  
- *   - typeOffsets:intvector (Required)
- *  
- *   Sets of UTC raw/dst offset pairs in seconds.  Entries at
- *   2n represents raw offset and 2n+1 represents dst offset
- *   paired with the raw offset at 2n.  The very first pair represents
- *   the initial zone offset (before the first transition) always.
- *
- *   - trans:intvector (Optional) 
- *  
- *   List of transition times represented by 32bit seconds from the
- *   epoch (1970-01-01T00:00Z) in ascending order.
- *  
- *   - transPre32/transPost32:intvector (Optional)
- *  
- *   List of transition times before/after 32bit minimum seconds.
- *   Each time is represented by a pair of 32bit integer.
- * 
- *   - typeMap:bin (Optional)
- *  
- *   Array of bytes representing the mapping between each transition
- *   time (transPre32/trans/transPost32) and its corresponding offset
- *   data (typeOffsets).
- *  
- *   - finalRule:string (Optional)
- *  
- *   If a recurrent transition rule is applicable to a zone forever
- *   after the final transition time, finalRule represents the rule
- *   in Rules data.
- *  
- *   - finalRaw:int (Optional)
- *   
- *   When finalRule is available, finalRaw is required and specifies
- *   the raw (base) offset of the rule.
- *   
- *   - finalYear:int (Optional)
- *   
- *   When finalRule is available, finalYear is required and specifies
- *   the start year of the rule.
- *   
- *   - links:intvector (Optional)
- *   
- *   When this zone data is shared with other zones, links specifies
- *   all zones including the zone itself.  Each zone is referenced by
- *   integer index.
- * 
- *  b. Link (int, length 1).  A link zone is an int resource.  The
- *  integer is the zone number of the target zone.  The key of this
- *  resource is an alternate name for the target zone.  This data
- *  is corresponding to Link data in the tz database.
- *
- *
- * 2. Rules.  These have keys corresponding to the Olson rule IDs,
- * with an underscore prepended, e.g., "_EU".  Each resource describes
- * the behavior of the given rule using an intvector, containing the
- * onset list, the cessation list, and the DST savings.  The onset and
- * cessation lists consist of the month, dowim, dow, time, and time
- * mode.  The end result is that the 11 integers describing the rule
- * can be passed directly into the SimpleTimeZone 13-argument
- * constructor (the other two arguments will be the raw offset, taken
- * from the complex zone element 5, and the ID string, which is not
- * used), with the times and the DST savings multiplied by 1000 to
- * scale from seconds to milliseconds.
- *
- * 3. Regions.  An array specifies mapping between zones and regions.
- * Each item is either a 2-letter ISO country code or "001"
- * (UN M.49 - World).  This data is generated from "zone.tab"
- * in the tz database.

- * <code>PersianCalendar</code> is a subclass of <code>Calendar</code>
- * that implements the Persian calendar.  It is used as the official
- * calendar in Iran.  This calendar is also known as the "Hijri Shamsi"
- * calendar, since it starts at the time of Mohammed's emigration (or
- * "hijra") to Medinah on Thursday, July 15, 622 AD (Julian) and is a
- * solar calendar system (or "shamsi").
- * <p>
- * The Persian calendar is strictly solar, and thus a Persian year has twelve
- * solar months. A Persian year is about 365 days long, except in leap years
- * which is 366 days long.
- * <p>
- * The six first months of Persian Calendar are 31 days long. The next five
- * months are 30 days long. The last month is 29 days long in normal years,
- * and 30 days long in leap years.

-/**
- * A transliteration rule used by
- * <code>RuleBasedTransliterator</code>.
- * <code>TransliterationRule</code> is an immutable object.
- *
- * <p>A rule consists of an input pattern and an output string.  When
- * the input pattern is matched, the output string is emitted.  The
- * input pattern consists of zero or more characters which are matched
- * exactly (the key) and optional context.  Context must match if it
- * is specified.  Context may be specified before the key, after the
- * key, or both.  The key, preceding context, and following context
- * may contain variables.  Variables represent a set of Unicode
- * characters, such as the letters <i>a</i> through <i>z</i>.
- * Variables are detected by looking up each character in a supplied
- * variable list to see if it has been so defined.
- *
- * <p>A rule may contain segments in its input string and segment
- * references in its output string.  A segment is a substring of the
- * input pattern, indicated by an offset and limit.  The segment may
- * be in the preceding or following context.  It may not span a
- * context boundary.  A segment reference is a special character in
- * the output string that causes a segment of the input string (not
- * the input pattern) to be copied to the output string.  The range of
- * special characters that represent segment references is defined by
- * RuleBasedTransliterator.Data.

- * Sets the daylight savings starting rule. For example, in the U.S., Daylight Savings
- * Time starts at the first Sunday in April, at 2 AM in standard time.
- * Therefore, you can set the start rule by calling:
- * setStartRule(TimeFields.APRIL, 1, TimeFields.SUNDAY, 2*60*60*1000);
- * The dayOfWeekInMonth and dayOfWeek parameters together specify how to calculate
- * the exact starting date.  Their exact meaning depend on their respective signs,
- * allowing various types of rules to be constructed, as follows:<ul>
- *   <li>If both dayOfWeekInMonth and dayOfWeek are positive, they specify the
- *       day of week in the month (e.g., (2, WEDNESDAY) is the second Wednesday
- *       of the month).
- *   <li>If dayOfWeek is positive and dayOfWeekInMonth is negative, they specify
- *       the day of week in the month counting backward from the end of the month.
- *       (e.g., (-1, MONDAY) is the last Monday in the month)
- *   <li>If dayOfWeek is zero and dayOfWeekInMonth is positive, dayOfWeekInMonth
- *       specifies the day of the month, regardless of what day of the week it is.
- *       (e.g., (10, 0) is the tenth day of the month)
- *   <li>If dayOfWeek is zero and dayOfWeekInMonth is negative, dayOfWeekInMonth
- *       specifies the day of the month counting backward from the end of the
- *       month, regardless of what day of the week it is (e.g., (-2, 0) is the
- *       next-to-last day of the month).
- *   <li>If dayOfWeek is negative and dayOfWeekInMonth is positive, they specify the
- *       first specified day of the week on or after the specfied day of the month.
- *       (e.g., (15, -SUNDAY) is the first Sunday after the 15th of the month
- *       [or the 15th itself if the 15th is a Sunday].)
- *   <li>If dayOfWeek and DayOfWeekInMonth are both negative, they specify the
- *       last specified day of the week on or before the specified day of the month.
- *       (e.g., (-20, -TUESDAY) is the last Tuesday before the 20th of the month

-// We represent the following flavors of rules:
-//       5        the fifth of the month
-//       lastSun  the last Sunday in the month
-//       lastMon  the last Monday in the month
-//       Sun>=8   first Sunday on or after the eighth
-//       Sun<=25  last Sunday on or before the 25th
-// This is further complicated by the fact that we need to remain
-// backward compatible with the 1.1 FCS.  Finally, we need to minimize
-// API changes.  In order to satisfy these requirements, we support
-// three representation systems, and we translate between them.
-//
-// INTERNAL REPRESENTATION
-// This is the format SimpleTimeZone objects take after construction or
-// streaming in is complete.  Rules are represented directly, using an
-// unencoded format.  We will discuss the start rule only below; the end
-// rule is analogous.
-//   startMode      Takes on enumerated values DAY_OF_MONTH,
-//                  DOW_IN_MONTH, DOW_AFTER_DOM, or DOW_BEFORE_DOM.
-//   startDay       The day of the month, or for DOW_IN_MONTH mode, a
-//                  value indicating which DOW, such as +1 for first,
-//                  +2 for second, -1 for last, etc.
-//   startDayOfWeek The day of the week.  Ignored for DAY_OF_MONTH.
-//
-// ENCODED REPRESENTATION
-// This is the format accepted by the constructor and by setStartRule()
-// and setEndRule().  It uses various combinations of positive, negative,
-// and zero values to encode the different rules.  This representation
-// allows us to specify all the different rule flavors without altering
-// the API.
-//   MODE              startMonth    startDay    startDayOfWeek
-//   DOW_IN_MONTH_MODE >=0           !=0         >0
-//   DOM_MODE          >=0           >0          ==0
-//   DOW_GE_DOM_MODE   >=0           >0          <0
-//   DOW_LE_DOM_MODE   >=0           <0          <0
-//   (no DST)          don't care    ==0         don't care
-//
-// STREAMED REPRESENTATION
-// We must retain binary compatibility with the 1.1 FCS.  The 1.1 code only
-// handles DOW_IN_MONTH_MODE and non-DST mode, the latter indicated by the
-// flag useDaylight.  When we stream an object out, we translate into an
-// approximate DOW_IN_MONTH_MODE representation so the object can be parsed
-// and used by 1.1 code.  Following that, we write out the full
-// representation separately so that contemporary code can recognize and
-// parse it.  The full representation is written in a "packed" format,
-// consisting of a version number, a length, and an array of bytes.  Future
-// versions of this class may specify different versions.  If they wish to
-// include additional data, they should do so by storing them after the
-// packed representation below.

-* Modification History:
-*
-*   Date        Name        Description
-*   12/05/96    clhuang     Creation.
-*   04/21/97    aliu        General clean-up and bug fixing.
-*   05/08/97    aliu        Fixed Hashtable code per code review.
-*   07/09/97    helena      Changed createInstance to createDefault.
-*   07/29/97    aliu        Updated with all-new list of 96 UNIX-derived
-*                           TimeZones.  Changed mechanism to load from static
-*                           array rather than resource bundle.
-*   07/07/1998  srl         Bugfixes from the Java side: UTC GMT CAT NST
-*                           Added getDisplayName API
-*                           going to add custom parsing.
-*
-*                           ISSUES:
-*                               - should getDisplayName cache something?
-*                               - should custom time zones be cached? [probably]
-*  08/10/98     stephen     Brought getDisplayName() API in-line w/ conventions
-*  08/19/98     stephen     Changed createTimeZone() to never return 0
-*  09/02/98     stephen     Added getOffset(monthLen) and hasSameRules()
-*  09/15/98     stephen     Added getStaticClassID()
-*  02/22/99     stephen     Removed character literals for EBCDIC safety
-*  05/04/99     stephen     Changed initDefault() for Mutex issues
-*  07/12/99     helena      HPUX 11 CC Port.
-*  12/03/99     aliu        Moved data out of static table into icudata.dll.
-*                           Substantial rewrite of zone lookup, default zone, and
-*                           available IDs code.  Misc. cleanup.

- * There are only 7 time units.
- * So, TimeUnit could be made as singleton 
- * (similar to uniset_props.cpp, or unorm.cpp,
- * in which a static TimeUnit* array is created, and 
- * the creatInstance() returns a const TimeUnit*).
- * But the constraint is TimeUnit is a data member of Measure.
- * But Measure (which is an existing API) does not expect it's "unit" member
- * as singleton. Meaure takes ownership of the "unit" member.
- * In its constructor, it does not take a const "unit" pointer.
- * Also, Measure can clone and destruct the "unit" pointer.
- * In order to preserve the old behavior and let Measure handle singleton "unit",  
- * 1. a flag need to be added in Measure; 
- * 2. a new constructor which takes const "unit" as parameter need to be added,
- *    and this new constructor will set the flag on.
- * 3. clone and destructor need to check upon this flag to distinguish on how
- *    to handle the "unit". 
- * 
- * Since TimeUnit is such a light weight object, comparing with the heavy weight
- * format operation, we decided to avoid the above complication.
- * 
- * So, both TimeUnit and CurrencyUnit (the 2 subclasses of MeasureUnit) are
- * immutable and non-singleton.
- *
- * Currently, TimeUnitAmount and CurrencyAmount are immutable.
- * If an application needs to create a long list of TimeUnitAmount on the same
- * time unit but different number, for example,
- * 1 hour, 2 hour, 3 hour, ................. 10,000 hour,
- * there might be performance hit because 10,000 TimeUnit object, 
- * although all are the same time unit, will be created in heap and deleted.
- *
- * To address this performance issue, if there is any in the future,
- * we should and need to change TimeUnitAmount and CurrencyAmount to be 
- * immutable by allowing a setter on the number.
- * Or we need to add 2 parallel mutable classes in order to 
- * preserve the existing API.
- * Or we can use freezable.

- * This DateFormatSymbolsSingleSetter class is a friend of DateFormatSymbols
- * solely for the purpose of avoiding to clone the array of strings
- * just to modify one of them and then setting all of them back.
- * For example, the old code looked like this:
- *  case UDAT_MONTHS:
- *    res = syms->getMonths(count);
- *    array = new UnicodeString[count];
- *    if(array == 0) {
- *      *status = U_MEMORY_ALLOCATION_ERROR;
- *      return;
- *    }
- *    uprv_arrayCopy(res, array, count);
- *    if(index < count)
- *      array[index] = val;
- *    syms->setMonths(array, count);
- *    break;
- *
- * Even worse, the old code actually cloned the entire DateFormatSymbols object,
- * cloned one value array, changed one value, and then made the SimpleDateFormat
- * replace its DateFormatSymbols object with the new one.

-* a number of characters in the text and tries to match the pattern from that
-* offset, the shift value can not be too large in case we miss some

-* possible representation of the pattern. Anyways, we'll err on the smaller
-* shift size. Hence the calculation for minlength.
-* Canonical match will be performed slightly differently. We'll split the
-* pattern into 3 parts, the prefix accents (PA), the middle string bounded by
-* the first and last base character (MS), the ending accents (EA). Matches
-* will be done on MS first, and only when we match MS then some processing
-* will be required for the prefix and end accents in order to determine if
-* they match PA and EA. Hence the default shift values
-* for the canonical match will take the size of either end's accent into

-/**
-* If a direction switch is required, we'll count the number of ces till the
-* beginning of the collation element iterator and iterate forwards that
-* number of times. This is so that we get to the correct point within the
-* string to continue the search in. Imagine when we are in the middle of the
-* normalization buffer when the change in direction is request. arrrgghh....
-* After searching the offset within the collation element iterator will be
-* shifted to the start of the match. If a match is not found, the offset would
-* have been set to the end of the text string in the collation element
-* iterator.
-* Okay, here's my take on normalization buffer. The only time when there can
-* be 2 matches within the same normalization is when the pattern is consists
-* of all accents. But since the offset returned is from the text string, we
-* should not confuse the caller by returning the second match within the
-* same normalization buffer. If we do, the 2 results will have the same match
-* offsets, and that'll be confusing. I'll return the next match that doesn't
-* fall within the same normalization buffer. Note this does not affect the
-* results of matches spanning the text and the normalization buffer.
-* The position to start searching is taken from the collation element
-* iterator. Callers of this API would have to set the offset in the collation
-* element iterator before using this method.

-//       value:  a string.  Most commonly one char in length, but can be more.
-//
-//    The keys are stored as a sorted array of 32 bit ints.
-//             bits 0-23    a code point value
-//             bits 24-31   length of value string, in UChars (between 1 and 256 UChars).
-//        The key table is sorted in ascending code point order.  (not on the
-//        32 bit int value, the flag bits do not participate in the sorting.)
-//
-//        Lookup is done by means of a binary search in the key table.
-//
-//    The corresponding values are kept in a parallel array of 16 bit ints.
-//        If the value string is of length 1, it is literally in the value array.
-//        For longer strings, the value array contains an index into the strings table.
-//
-//    String Table:
-//       The strings table contains all of the value strings (those of length two or greater)
-//       concatentated together into one long UChar (UTF-16) array.
-//
-//       There is no nul character or other mark between adjacent strings.

-//  Changes from format version 1 to format version 2:
-//      1) Removal of the whole-script confusable data tables.
-//      2) Removal of the SL/SA/ML/MA and multi-table flags in the key bitmask.
-//      3) Expansion of string length value in the key bitmask from 2 bits to 8 bits.

-//  SpoofData
-//
-//    A small class that wraps the raw (usually memory mapped) spoof data.
-//    Serves two primary functions:
-//      1.  Convenience.  Contains real pointers to the data, to avoid dealing with
-//          the offsets in the raw data.
-//      2.  Reference counting.  When a spoof checker is cloned, the raw data is shared
-//          and must be retained until all checkers using the data are closed.
-//    Nothing in this struct includes state that is specific to any particular
-//    USpoofDetector object.

-/**
- * AlphabeticIndex supports the creation of a UI index appropriate for a given language.
- * It can support either direct use, or use with a client that doesn't support localized collation.
- * The following is an example of what an index might look like in a UI:
- * 
- * <pre>
- *  <b>... A B C D E F G H I J K L M N O P Q R S T U V W X Y Z  ...</b>
- *
- *  <b>A</b>
- *     Addison
- *     Albertson
- *     Azensky
- *  <b>B</b>
- *     Baker
- *  ...
- * </pre>
- *
- * The class can generate a list of labels for use as a UI "index", that is, a list of
- * clickable characters (or character sequences) that allow the user to see a segment
- * (bucket) of a larger "target" list. That is, each label corresponds to a bucket in
- * the target list, where everything in the bucket is greater than or equal to the character
- * (according to the locale's collation). Strings can be added to the index;
- * they will be in sorted order in the right bucket.
- * <p>
- * The class also supports having buckets for strings before the first (underflow),
- * after the last (overflow), and between scripts (inflow). For example, if the index
- * is constructed with labels for Russian and English, Greek characters would fall
- * into an inflow bucket between the other two scripts.
- * <p>
- * The AlphabeticIndex class is not intended for public subclassing.
- *
- * <p><em>Note:</em> If you expect to have a lot of ASCII or Latin characters
- * as well as characters from the user's language,
- * then it is a good idea to call addLabels(Locale::getEnglish(), status).</p>
- *
- * <h2>Direct Use</h2>
- * <p>The following shows an example of building an index directly.
- *  The "show..." methods below are just to illustrate usage.
- *
- * <pre>
- * // Create a simple index.  "Item" is assumed to be an application
- * // defined type that the application's UI and other processing knows about,
- * //  and that has a name.
- *
- * UErrorCode status = U_ZERO_ERROR;
- * AlphabeticIndex index = new AlphabeticIndex(desiredLocale, status);
- * index->addLabels(additionalLocale, status);
- * for (Item *item in some source of Items ) {
- *     index->addRecord(item->name(), item, status);
- * }
- * ...
- * // Show index at top. We could skip or gray out empty buckets
- *
- * while (index->nextBucket(status)) {
- *     if (showAll || index->getBucketRecordCount() != 0) {
- *         showLabelAtTop(UI, index->getBucketLabel());
- *     }
- * }
- *  ...
- * // Show the buckets with their contents, skipping empty buckets
- *
- * index->resetBucketIterator(status);
- * while (index->nextBucket(status)) {
- *    if (index->getBucketRecordCount() != 0) {
- *        showLabelInList(UI, index->getBucketLabel());
- *        while (index->nextRecord(status)) {
- *            showIndexedItem(UI, static_cast<Item *>(index->getRecordData()))
- * </pre>
- *
- * The caller can build different UIs using this class.
- * For example, an index character could be omitted or grayed-out
- * if its bucket is empty. Small buckets could also be combined based on size, such as:
- *
- * <pre>
- * <b>... A-F G-N O-Z ...</b>
- * </pre>
- *
- * <h2>Client Support</h2>
- * <p>Callers can also use the AlphabeticIndex::ImmutableIndex, or the AlphabeticIndex itself,
- * to support sorting on a client that doesn't support AlphabeticIndex functionality.
- *
- * <p>The ImmutableIndex is both immutable and thread-safe.
- * The corresponding AlphabeticIndex methods are not thread-safe because
- * they "lazily" build the index buckets.
- * <ul>
- * <li>ImmutableIndex.getBucket(index) provides random access to all
- *     buckets and their labels and label types.
- * <li>The AlphabeticIndex bucket iterator or ImmutableIndex.getBucket(0..getBucketCount-1)
- *     can be used to get a list of the labels,
- *     such as "...", "A", "B",..., and send that list to the client.
- * <li>When the client has a new name, it sends that name to the server.
- * The server needs to call the following methods,
- * and communicate the bucketIndex and collationKey back to the client.
- *
- * <pre>
- * int32_t bucketIndex = index.getBucketIndex(name, status);
- * const UnicodeString &label = immutableIndex.getBucket(bucketIndex)->getLabel();  // optional
- * int32_t skLength = collator.getSortKey(name, sk, skCapacity);
- * </pre>
- *
- * <li>The client would put the name (and associated information) into its bucket for bucketIndex. The sort key sk is a
- * sequence of bytes that can be compared with a binary compare, and produce the right localized result.</li>
- * </ul>

-/**
- * The BreakIterator class implements methods for finding the location
- * of boundaries in text. BreakIterator is an abstract base class.
- * Instances of BreakIterator maintain a current position and scan over
- * text returning the index of characters where boundaries occur.
- * <p>
- * Line boundary analysis determines where a text string can be broken
- * when line-wrapping. The mechanism correctly handles punctuation and
- * hyphenated words.
- * <p>
- * Sentence boundary analysis allows selection with correct
- * interpretation of periods within numbers and abbreviations, and
- * trailing punctuation marks such as quotation marks and parentheses.
- * <p>
- * Word boundary analysis is used by search and replace functions, as
- * well as within text editing applications that allow the user to
- * select words with a double click. Word selection provides correct
- * interpretation of punctuation marks within and following
- * words. Characters that are not part of a word, such as symbols or
- * punctuation marks, have word-breaks on both sides.
- * <p>
- * Character boundary analysis allows users to interact with
- * characters as they expect to, for example, when moving the cursor
- * through a text string. Character boundary analysis provides correct
- * navigation of through character strings, regardless of how the
- * character is stored.  For example, an accented character might be
- * stored as a base character and a diacritical mark. What users
- * consider to be a character can differ between languages.
- * <p>
- * The text boundary positions are found according to the rules
- * described in Unicode Standard Annex #29, Text Boundaries, and
- * Unicode Standard Annex #14, Line Breaking Properties.  These
- * are available at http://www.unicode.org/reports/tr14/ and
- * http://www.unicode.org/reports/tr29/.
- * <p>
- * In addition to the C++ API defined in this header file, a
- * plain C API with equivalent functionality is defined in the
- * file ubrk.h
- * <p>
- * Code snippets illustrating the use of the Break Iterator APIs
- * are available in the ICU User Guide,
- * http://icu-project.org/userguide/boundaryAnalysis.html
- * and in the sample program icu/source/samples/break/break.cpp

-// Abstract interface that consumes a sequence of bytes (ByteSink).
-//
-// Used so that we can write a single piece of code that can operate
-// on a variety of output string types.
-//
-// Various implementations of this interface are provided:
-//   ByteSink:
-//      CheckedArrayByteSink    Write to a flat array, with bounds checking
-//      StringByteSink          Write to an STL string
-
-// This code is a contribution of Google code, and the style used here is
-// a compromise between the original Google code and the ICU coding guidelines.
-// For example, data types are ICU-ified (size_t,int->int32_t),
-// and API comments doxygen-ified, but function names and behavior are
-// as in the original, if possible.
-// Assertion-style error handling, not available in ICU, was changed to
-// parameter "pinning" similar to UnicodeString.
-//
-// In addition, this is only a partial port of the original Google code,
-// limited to what was needed so far. The (nearly) complete original code
-// is in the ICU svn repository at icuhtml/trunk/design/strings/contrib
-// (see ICU ticket 6765, r25517).

-    // The trie consists of a series of byte-serialized nodes for incremental
-    // string/byte sequence matching. The root node is at the beginning of the trie data.
-    //
-    // Types of nodes are distinguished by their node lead byte ranges.
-    // After each node, except a final-value node, another node follows to
-    // encode match values or continue matching further bytes.
-    //
-    // Node types:
-    //  - Value node: Stores a 32-bit integer in a compact, variable-length format.
-    //    The value is for the string/byte sequence so far.
-    //    One node bit indicates whether the value is final or whether
-    //    matching continues with the next node.
-    //  - Linear-match node: Matches a number of bytes.
-    //  - Branch node: Branches to other nodes according to the current input byte.
-    //    The node byte is the length of the branch (number of bytes to select from)
-    //    minus 1. It is followed by a sub-node:
-    //    - If the length is at most kMaxBranchLinearSubNodeLength, then
-    //      there are length-1 (key, value) pairs and then one more comparison byte.
-    //      If one of the key bytes matches, then the value is either a final value for
-    //      the string/byte sequence so far, or a "jump" delta to the next node.
-    //      If the last byte matches, then matching continues with the next node.
-    //      (Values have the same encoding as value nodes.)
-    //    - If the length is greater than kMaxBranchLinearSubNodeLength, then
-    //      there is one byte and one "jump" delta.
-    //      If the input byte is less than the sub-node byte, then "jump" by delta to
-    //      the next sub-node which will have a length of length/2.
-    //      (The delta has its own compact encoding.)
-    //      Otherwise, skip the "jump" delta to the next sub-node
-    //      which will have a length of length-length/2.
-
-    // Node lead byte values.
-

-/**
- * `Calendar` is an abstract base class for converting between
- * a `UDate` object and a set of integer fields such as
- * `YEAR`, `MONTH`, `DAY`, `HOUR`, and so on.
- * (A `UDate` object represents a specific instant in
- * time with millisecond precision. See UDate
- * for information about the `UDate` class.)
- *
- * Subclasses of `Calendar` interpret a `UDate`
- * according to the rules of a specific calendar system.
- * The most commonly used subclass of `Calendar` is
- * `GregorianCalendar`. Other subclasses could represent
- * the various types of lunar calendars in use in many parts of the world.
- *
- * **NOTE**: (ICU 2.6) The subclass interface should be considered unstable -
- * it WILL change.
- *
- * Like other locale-sensitive classes, `Calendar` provides a
- * static method, `createInstance`, for getting a generally useful
- * object of this type. `Calendar`'s `createInstance` method
- * returns the appropriate `Calendar` subclass whose
- * time fields have been initialized with the current date and time:
- *
- *     Calendar *rightNow = Calendar::createInstance(errCode);
- *
- * A `Calendar` object can produce all the time field values
- * needed to implement the date-time formatting for a particular language
- * and calendar style (for example, Japanese-Gregorian, Japanese-Traditional).
- *
- * When computing a `UDate` from time fields, some special circumstances
- * may arise: there may be insufficient information to compute the
- * `UDate` (such as only year and month but no day in the month),
- * there may be inconsistent information (such as "Tuesday, July 15, 1996"
- * -- July 15, 1996 is actually a Monday), or the input time might be ambiguous
- * because of time zone transition.
- *
- * **Insufficient information.** The calendar will use default
- * information to specify the missing fields. This may vary by calendar; for
- * the Gregorian calendar, the default for a field is the same as that of the
- * start of the epoch: i.e., YEAR = 1970, MONTH = JANUARY, DATE = 1, etc.
- *
- * **Inconsistent information.** If fields conflict, the calendar
- * will give preference to fields set more recently. For example, when
- * determining the day, the calendar will look for one of the following
- * combinations of fields.  The most recent combination, as determined by the
- * most recently set single field, will be used.
- *
- *     MONTH + DAY_OF_MONTH
- *     MONTH + WEEK_OF_MONTH + DAY_OF_WEEK
- *     MONTH + DAY_OF_WEEK_IN_MONTH + DAY_OF_WEEK
- *     DAY_OF_YEAR
- *     DAY_OF_WEEK + WEEK_OF_YEAR
- *
- * For the time of day:
- *
- *     HOUR_OF_DAY
- *     AM_PM + HOUR
- *
- * **Ambiguous Wall Clock Time.** When time offset from UTC has
- * changed, it produces an ambiguous time slot around the transition. For example,
- * many US locations observe daylight saving time. On the date switching to daylight
- * saving time in US, wall clock time jumps from 12:59 AM (standard) to 2:00 AM
- * (daylight). Therefore, wall clock time from 1:00 AM to 1:59 AM do not exist on
- * the date. When the input wall time fall into this missing time slot, the ICU
- * Calendar resolves the time using the UTC offset before the transition by default.
- * In this example, 1:30 AM is interpreted as 1:30 AM standard time (non-exist),
- * so the final result will be 2:30 AM daylight time.
- *
- * On the date switching back to standard time, wall clock time is moved back one
- * hour at 2:00 AM. So wall clock time from 1:00 AM to 1:59 AM occur twice. In this
- * case, the ICU Calendar resolves the time using the UTC offset after the transition
- * by default. For example, 1:30 AM on the date is resolved as 1:30 AM standard time.
- *
- * Ambiguous wall clock time resolution behaviors can be customized by Calendar APIs
- * {@link #setRepeatedWallTimeOption} and {@link #setSkippedWallTimeOption}.
- * These methods are available in ICU 49 or later versions.
- *
- * **Note:** for some non-Gregorian calendars, different
- * fields may be necessary for complete disambiguation. For example, a full
- * specification of the historical Arabic astronomical calendar requires year,
- * month, day-of-month *and* day-of-week in some cases.
- *
- * **Note:** There are certain possible ambiguities in
- * interpretation of certain singular times, which are resolved in the
- * following ways:
- *
- *   1. 24:00:00 "belongs" to the following day. That is,
- *      23:59 on Dec 31, 1969 < 24:00 on Jan 1, 1970 < 24:01:00 on Jan 1, 1970
- *   2. Although historically not precise, midnight also belongs to "am",
- *      and noon belongs to "pm", so on the same day,
- *      12:00 am (midnight) < 12:01 am, and 12:00 pm (noon) < 12:01 pm
- *
- * The date or time format strings are not part of the definition of a
- * calendar, as those must be modifiable or overridable by the user at
- * runtime. Use `DateFormat` to format dates.
- *
- * `Calendar` provides an API for field "rolling", where fields
- * can be incremented or decremented, but wrap around. For example, rolling the
- * month up in the date December 12, **1996** results in
- * January 12, **1996**.
- *
- * `Calendar` also provides a date arithmetic function for
- * adding the specified (signed) amount of time to a particular time field.
- * For example, subtracting 5 days from the date `September 12, 1996`
- * results in `September 7, 1996`.
- *
- * ***Supported range***
- *
- * The allowable range of `Calendar` has been narrowed. `GregorianCalendar` used
- * to attempt to support the range of dates with millisecond values from
- * `Long.MIN_VALUE` to `Long.MAX_VALUE`. The new `Calendar` protocol specifies the
- * maximum range of supportable dates as those having Julian day numbers
- * of `-0x7F000000` to `+0x7F000000`. This corresponds to years from ~5,800,000 BCE
- * to ~5,800,000 CE. Programmers should use the protected constants in `Calendar` to
- * specify an extremely early or extremely late date.
- *
- * <p>
- * The Japanese calendar uses a combination of era name and year number.
- * When an emperor of Japan abdicates and a new emperor ascends the throne,
- * a new era is declared and year number is reset to 1. Even if the date of
- * abdication is scheduled ahead of time, the new era name might not be
- * announced until just before the date. In such case, ICU4C may include
- * a start date of future era without actual era name, but not enabled
- * by default. ICU4C users who want to test the behavior of the future era
- * can enable the tentative era by:
- * <ul>
- * <li>Environment variable <code>ICU_ENABLE_TENTATIVE_ERA=true</code>.</li>
- * </ul>

-/**
- * Abstract class that defines an API for forward-only iteration
- * on text objects.
- * This is a minimal interface for iteration without random access
- * or backwards iteration. It is especially useful for wrapping
- * streams with converters into an object for collation or
- * normalization.
- *
- * <p>Characters can be accessed in two ways: as code units or as
- * code points.
- * Unicode code points are 21-bit integers and are the scalar values
- * of Unicode characters. ICU uses the type UChar32 for them.
- * Unicode code units are the storage units of a given
- * Unicode/UCS Transformation Format (a character encoding scheme).
- * With UTF-16, all code points can be represented with either one
- * or two code units ("surrogates").
- * String storage is typically based on code units, while properties
- * of characters are typically determined using code point values.
- * Some processes may be designed to work with sequences of code units,
- * or it may be known that all characters that are important to an
- * algorithm can be represented with single code units.
- * Other processes will need to use the code point access functions.</p>
- *
- * <p>ForwardCharacterIterator provides nextPostInc() to access
- * a code unit and advance an internal position into the text object,
- * similar to a <code>return text[position++]</code>.<br>
- * It provides next32PostInc() to access a code point and advance an internal
- * position.</p>
- *
- * <p>next32PostInc() assumes that the current position is that of
- * the beginning of a code point, i.e., of its first code unit.
- * After next32PostInc(), this will be true again.
- * In general, access to code units and code points in the same
- * iteration loop should not be mixed. In UTF-16, if the current position
- * is on a second code unit (Low Surrogate), then only that code unit
- * is returned even by next32PostInc().</p>
- *
- * <p>For iteration with either function, there are two ways to
- * check for the end of the iteration. When there are no more
- * characters in the text object:
- * <ul>
- * <li>The hasNext() function returns FALSE.</li>
- * <li>nextPostInc() and next32PostInc() return DONE
- *     when one attempts to read beyond the end of the text object.</li>
- * </ul>
- *
- * Example:
- * \code 
- * void function1(ForwardCharacterIterator &it) {
- *     UChar32 c;
- *     while(it.hasNext()) {
- *         c=it.next32PostInc();
- *         // use c
- *     }
- * }
- *
- * void function1(ForwardCharacterIterator &it) {
- *     char16_t c;
- *     while((c=it.nextPostInc())!=ForwardCharacterIterator::DONE) {
- *         // use c
- *      }
- *  }
- * \endcode
- * </p>

-/**
- * Abstract class that defines an API for iteration
- * on text objects.
- * This is an interface for forward and backward iteration
- * and random access into a text object.
- *
- * <p>The API provides backward compatibility to the Java and older ICU
- * CharacterIterator classes but extends them significantly:
- * <ol>
- * <li>CharacterIterator is now a subclass of ForwardCharacterIterator.</li>
- * <li>While the old API functions provided forward iteration with
- *     "pre-increment" semantics, the new one also provides functions
- *     with "post-increment" semantics. They are more efficient and should
- *     be the preferred iterator functions for new implementations.
- *     The backward iteration always had "pre-decrement" semantics, which
- *     are efficient.</li>
- * <li>Just like ForwardCharacterIterator, it provides access to
- *     both code units and code points. Code point access versions are available
- *     for the old and the new iteration semantics.</li>
- * <li>There are new functions for setting and moving the current position
- *     without returning a character, for efficiency.</li>
- * </ol>
- *
- * See ForwardCharacterIterator for examples for using the new forward iteration
- * functions. For backward iteration, there is also a hasPrevious() function
- * that can be used analogously to hasNext().
- * The old functions work as before and are shown below.</p>
- *
- * <p>Examples for some of the new functions:</p>
- *
- * Forward iteration with hasNext():
- * \code
- * void forward1(CharacterIterator &it) {
- *     UChar32 c;
- *     for(it.setToStart(); it.hasNext();) {
- *         c=it.next32PostInc();
- *         // use c
- *     }
- *  }
- * \endcode
- * Forward iteration more similar to loops with the old forward iteration,
- * showing a way to convert simple for() loops:
- * \code
- * void forward2(CharacterIterator &it) {
- *     char16_t c;
- *     for(c=it.firstPostInc(); c!=CharacterIterator::DONE; c=it.nextPostInc()) {
- *          // use c
- *      }
- * }
- * \endcode
- * Backward iteration with setToEnd() and hasPrevious():
- * \code
- *  void backward1(CharacterIterator &it) {
- *      UChar32 c;
- *      for(it.setToEnd(); it.hasPrevious();) {
- *         c=it.previous32();
- *          // use c
- *      }
- *  }
- * \endcode
- * Backward iteration with a more traditional for() loop:
- * \code
- * void backward2(CharacterIterator &it) {
- *     char16_t c;
- *     for(c=it.last(); c!=CharacterIterator::DONE; c=it.previous()) {
- *         // use c
- *      }
- *  }
- * \endcode
- *
- * Example for random access:
- * \code
- *  void random(CharacterIterator &it) {
- *      // set to the third code point from the beginning
- *      it.move32(3, CharacterIterator::kStart);
- *      // get a code point from here without moving the position
- *      UChar32 c=it.current32();
- *      // get the position
- *      int32_t pos=it.getIndex();
- *      // get the previous code unit
- *      char16_t u=it.previous();
- *      // move back one more code unit
- *      it.move(-1, CharacterIterator::kCurrent);
- *      // set the position back to where it was
- *      // and read the same code point c and move beyond it
- *      it.setIndex(pos);
- *      if(c!=it.next32PostInc()) {
- *          exit(1); // CharacterIterator inconsistent
- *      }
- *  }
- * \endcode
- *
- * <p>Examples, especially for the old API:</p>
- *
- * Function processing characters, in this example simple output
- * <pre>
- * \code
- *  void processChar( char16_t c )
- *  {
- *      cout << " " << c;
- *  }
- * \endcode
- * </pre>
- * Traverse the text from start to finish
- * <pre> 
- * \code
- *  void traverseForward(CharacterIterator& iter)
- *  {
- *      for(char16_t c = iter.first(); c != CharacterIterator.DONE; c = iter.next()) {
- *          processChar(c);
- *      }
- *  }
- * \endcode
- * </pre>
- * Traverse the text backwards, from end to start
- * <pre>
- * \code
- *  void traverseBackward(CharacterIterator& iter)
- *  {
- *      for(char16_t c = iter.last(); c != CharacterIterator.DONE; c = iter.previous()) {
- *          processChar(c);
- *      }
- *  }
- * \endcode
- * </pre>
- * Traverse both forward and backward from a given position in the text. 
- * Calls to notBoundary() in this example represents some additional stopping criteria.
- * <pre>
- * \code
- * void traverseOut(CharacterIterator& iter, int32_t pos)
- * {
- *      char16_t c;
- *      for (c = iter.setIndex(pos);
- *      c != CharacterIterator.DONE && (Unicode::isLetter(c) || Unicode::isDigit(c));
- *          c = iter.next()) {}
- *      int32_t end = iter.getIndex();
- *      for (c = iter.setIndex(pos);
- *          c != CharacterIterator.DONE && (Unicode::isLetter(c) || Unicode::isDigit(c));
- *          c = iter.previous()) {}
- *      int32_t start = iter.getIndex() + 1;
- *  
- *      cout << "start: " << start << " end: " << end << endl;
- *      for (c = iter.setIndex(start); iter.getIndex() < end; c = iter.next() ) {
- *          processChar(c);
- *     }
- *  }
- * \endcode
- * </pre>
- * Creating a StringCharacterIterator and calling the test functions
- * <pre>
- * \code
- *  void CharacterIterator_Example( void )
- *   {
- *       cout << endl << "===== CharacterIterator_Example: =====" << endl;
- *       UnicodeString text("Ein kleiner Satz.");
- *       StringCharacterIterator iterator(text);

-class MessageFormat;
-
-/**
- * ChoiceFormat converts between ranges of numeric values and strings for those ranges.
- * The strings must conform to the MessageFormat pattern syntax.
- *
- * <p><em><code>ChoiceFormat</code> is probably not what you need.
- * Please use <code>MessageFormat</code>
- * with <code>plural</code> arguments for proper plural selection,
- * and <code>select</code> arguments for simple selection among a fixed set of choices!</em></p>
- *
- * <p>A <code>ChoiceFormat</code> splits
- * the real number line \htmlonly<code>-&#x221E;</code> to
- * <code>+&#x221E;</code>\endhtmlonly into two
- * or more contiguous ranges. Each range is mapped to a
- * string.</p>
- *
- * <p><code>ChoiceFormat</code> was originally intended
- * for displaying grammatically correct
- * plurals such as &quot;There is one file.&quot; vs. &quot;There are 2 files.&quot;
- * <em>However,</em> plural rules for many languages
- * are too complex for the capabilities of ChoiceFormat,
- * and its requirement of specifying the precise rules for each message
- * is unmanageable for translators.</p>
- *
- * <p>There are two methods of defining a <code>ChoiceFormat</code>; both
- * are equivalent.  The first is by using a string pattern. This is the
- * preferred method in most cases.  The second method is through direct
- * specification of the arrays that logically make up the
- * <code>ChoiceFormat</code>.</p>
- *
- * <p>Note: Typically, choice formatting is done (if done at all) via <code>MessageFormat</code>
- * with a <code>choice</code> argument type,
- * rather than using a stand-alone <code>ChoiceFormat</code>.</p>
- *
- * <h5>Patterns and Their Interpretation</h5>
- *
- * <p>The pattern string defines the range boundaries and the strings for each number range.
- * Syntax:
- * <pre>
- * choiceStyle = number separator message ('|' number separator message)*
- * number = normal_number | ['-'] \htmlonly&#x221E;\endhtmlonly (U+221E, infinity)
- * normal_number = double value (unlocalized ASCII string)
- * separator = less_than | less_than_or_equal
- * less_than = '<'
- * less_than_or_equal = '#' | \htmlonly&#x2264;\endhtmlonly (U+2264)
- * message: see {@link MessageFormat}
- * </pre>
- * Pattern_White_Space between syntax elements is ignored, except
- * around each range's sub-message.</p>
- *
- * <p>Each numeric sub-range extends from the current range's number
- * to the next range's number.
- * The number itself is included in its range if a <code>less_than_or_equal</code> sign is used,
- * and excluded from its range (and instead included in the previous range)
- * if a <code>less_than</code> sign is used.</p>
- *
- * <p>When a <code>ChoiceFormat</code> is constructed from
- * arrays of numbers, closure flags and strings,
- * they are interpreted just like
- * the sequence of <code>(number separator string)</code> in an equivalent pattern string.
- * <code>closure[i]==TRUE</code> corresponds to a <code>less_than</code> separator sign.
- * The equivalent pattern string will be constructed automatically.</p>
- *
- * <p>During formatting, a number is mapped to the first range
- * where the number is not greater than the range's upper limit.
- * That range's message string is returned. A NaN maps to the very first range.</p>
- *
- * <p>During parsing, a range is selected for the longest match of
- * any range's message. That range's number is returned, ignoring the separator/closure.
- * Only a simple string match is performed, without parsing of arguments that
- * might be specified in the message strings.</p>
- *
- * <p>Note that the first range's number is ignored in formatting
- * but may be returned from parsing.</p>
- *
- * <h5>Examples</h5>
- *
- * <p>Here is an example of two arrays that map the number
- * <code>1..7</code> to the English day of the week abbreviations
- * <code>Sun..Sat</code>. No closures array is given; this is the same as
- * specifying all closures to be <code>FALSE</code>.</p>
- *
- * <pre>    {1,2,3,4,5,6,7},
- *     {&quot;Sun&quot;,&quot;Mon&quot;,&quot;Tue&quot;,&quot;Wed&quot;,&quot;Thur&quot;,&quot;Fri&quot;,&quot;Sat&quot;}</pre>
- *
- * <p>Here is an example that maps the ranges [-Inf, 1), [1, 1], and (1,
- * +Inf] to three strings. That is, the number line is split into three
- * ranges: x &lt; 1.0, x = 1.0, and x &gt; 1.0.
- * (The round parentheses in the notation above indicate an exclusive boundary,
- * like the turned bracket in European notation: [-Inf, 1) == [-Inf, 1[  )</p>
- *
- * <pre>    {0, 1, 1},
- *     {FALSE, FALSE, TRUE},
- *     {&quot;no files&quot;, &quot;one file&quot;, &quot;many files&quot;}</pre>
- *
- * <p>Here is an example that shows formatting and parsing: </p>

- *   #include <unicode/unistr.h>

- *       ChoiceFormat fmt(limits, monthNames, 7);
- *       UnicodeString str;
- *       char buf[256];
- *       for (double x = 1.0; x <= 8.0; x += 1.0) {
- *           fmt.format(x, str);
- *           str.extract(0, str.length(), buf, 256, "");
- *           str.truncate(0);

-     * The intervals may be closed, half open, or open.  This affects

-/**
-* The CollationElementIterator class is used as an iterator to walk through     
-* each character of an international string. Use the iterator to return the
-* ordering priority of the positioned character. The ordering priority of a 
-* character, which we refer to as a key, defines how a character is collated in 
-* the given collation object.
-* For example, consider the following in Slovak and in traditional Spanish collation:
-* <pre>
-*        "ca" -> the first key is key('c') and second key is key('a').
-*        "cha" -> the first key is key('ch') and second key is key('a').</pre>
-* And in German phonebook collation,
-* <pre> \htmlonly       "&#x00E6;b"-> the first key is key('a'), the second key is key('e'), and
-*        the third key is key('b'). \endhtmlonly </pre>
-* The key of a character, is an integer composed of primary order(short),
-* secondary order(char), and tertiary order(char). Java strictly defines the 
-* size and signedness of its primitive data types. Therefore, the static
-* functions primaryOrder(), secondaryOrder(), and tertiaryOrder() return 
-* int32_t to ensure the correctness of the key value.
-* <p>Example of the iterator usage: (without error checking)
-* <pre>
-* \code
-*   void CollationElementIterator_Example()
-*   {
-*       UnicodeString str = "This is a test";
-*       UErrorCode success = U_ZERO_ERROR;
-*       RuleBasedCollator* rbc =
-*           (RuleBasedCollator*) RuleBasedCollator::createInstance(success);
-*       CollationElementIterator* c =
-*           rbc->createCollationElementIterator( str );
-*       int32_t order = c->next(success);
-*       c->reset();
-*       order = c->previous(success);
-*       delete c;
-*       delete rbc;
-*   }
-* \endcode
-* </pre>
-* <p>
-* The method next() returns the collation order of the next character based on
-* the comparison level of the collator. The method previous() returns the
-* collation order of the previous character based on the comparison level of
-* the collator. The Collation Element Iterator moves only in one direction
-* between calls to reset(), setOffset(), or setText(). That is, next() 
-* and previous() can not be inter-used. Whenever previous() is to be called after 
-* next() or vice versa, reset(), setOffset() or setText() has to be called first
-* to reset the status, shifting pointers to either the end or the start of
-* the string (reset() or setText()), or the specified position (setOffset()).
-* Hence at the next call of next() or previous(), the first or last collation order,
-* or collation order at the spefcifieid position will be returned. If a change of
-* direction is done without one of these calls, the result is undefined.
-* <p>
-* The result of a forward iterate (next()) and reversed result of the backward
-* iterate (previous()) on the same string are equivalent, if collation orders
-* with the value 0 are ignored.
-* Character based on the comparison level of the collator.  A collation order 
-* consists of primary order, secondary order and tertiary order.  The data 
-* type of the collation order is <strong>int32_t</strong>. 
-*
-* Note, CollationElementIterator should not be subclassed.
-* @see     Collator
-* @see     RuleBasedCollator

-* The <code>Collator</code> class performs locale-sensitive string
-* comparison.<br>
-* You use this class to build searching and sorting routines for natural
-* language text.
-* <p>
-* <code>Collator</code> is an abstract base class. Subclasses implement
-* specific collation strategies. One subclass,
-* <code>RuleBasedCollator</code>, is currently provided and is applicable
-* to a wide set of languages. Other subclasses may be created to handle more
-* specialized needs.
-* <p>
-* Like other locale-sensitive classes, you can use the static factory method,
-* <code>createInstance</code>, to obtain the appropriate
-* <code>Collator</code> object for a given locale. You will only need to
-* look at the subclasses of <code>Collator</code> if you need to
-* understand the details of a particular collation strategy or if you need to
-* modify that strategy.
-* <p>
-* The following example shows how to compare two strings using the
-* <code>Collator</code> for the default locale.
-* \htmlonly<blockquote>\endhtmlonly
-* <pre>
-* \code
-* // Compare two strings in the default locale
-* UErrorCode success = U_ZERO_ERROR;
-* Collator* myCollator = Collator::createInstance(success);
-* if (myCollator->compare("abc", "ABC") < 0)
-*   cout << "abc is less than ABC" << endl;
-* else
-*   cout << "abc is greater than or equal to ABC" << endl;
-* \endcode
-* </pre>
-* \htmlonly</blockquote>\endhtmlonly
-* <p>
-* You can set a <code>Collator</code>'s <em>strength</em> attribute to
-* determine the level of difference considered significant in comparisons.
-* Five strengths are provided: <code>PRIMARY</code>, <code>SECONDARY</code>,
-* <code>TERTIARY</code>, <code>QUATERNARY</code> and <code>IDENTICAL</code>.
-* The exact assignment of strengths to language features is locale dependent.
-* For example, in Czech, "e" and "f" are considered primary differences,
-* while "e" and "\u00EA" are secondary differences, "e" and "E" are tertiary
-* differences and "e" and "e" are identical. The following shows how both case
-* and accents could be ignored for US English.
-* \htmlonly<blockquote>\endhtmlonly
-* <pre>
-* \code
-* //Get the Collator for US English and set its strength to PRIMARY
-* UErrorCode success = U_ZERO_ERROR;
-* Collator* usCollator = Collator::createInstance(Locale::getUS(), success);
-* usCollator->setStrength(Collator::PRIMARY);
-* if (usCollator->compare("abc", "ABC") == 0)
-*     cout << "'abc' and 'ABC' strings are equivalent with strength PRIMARY" << endl;
-* \endcode
-* </pre>
-* \htmlonly</blockquote>\endhtmlonly
-*
-* The <code>getSortKey</code> methods
-* convert a string to a series of bytes that can be compared bitwise against
-* other sort keys using <code>strcmp()</code>. Sort keys are written as
-* zero-terminated byte strings.
-*
-* Another set of APIs returns a <code>CollationKey</code> object that wraps
-* the sort key bytes instead of returning the bytes themselves.
-* </p>
-* <p>
-* <strong>Note:</strong> <code>Collator</code>s with different Locale,
-* and CollationStrength settings will return different sort
-* orders for the same set of strings. Locales have specific collation rules,
-* and the way in which secondary and tertiary differences are taken into
-* account, for example, will result in a different sorting order for same
-* strings.

-     * built on top of it with additional language-specific modifications.
-     *
-     * For some languages, multiple collation types are available;
-     * for example, "de@collation=phonebook".
-     * Starting with ICU 54, collation attributes can be specified via locale keywords as well,
-     * in the old locale extension syntax ("el@colCaseFirst=upper")
-     * or in language tag syntax ("el-u-kf-upper").

-     * The UErrorCode& err parameter is used to return status information to the user.
-     * To check whether the construction succeeded or not, you should check
-     * the value of U_SUCCESS(err).  If you wish more detailed information, you
-     * can check for informational error results which still indicate success.
-     * U_USING_FALLBACK_ERROR indicates that a fall back locale was used.  For
-     * example, 'de_CH' was requested, but nothing was found there, so 'de' was
-     * used.  U_USING_DEFAULT_ERROR indicates that the default locale data was
-     * used; neither the requested locale nor any of its fall back locales
-     * could be found.
-     *
-     * The caller owns the returned object and is responsible for deleting it.

-/**
- * DateFormat is an abstract class for a family of classes that convert dates and
- * times from their internal representations to textual form and back again in a
- * language-independent manner. Converting from the internal representation (milliseconds
- * since midnight, January 1, 1970) to text is known as "formatting," and converting
- * from text to millis is known as "parsing."  We currently define only one concrete
- * subclass of DateFormat: SimpleDateFormat, which can handle pretty much all normal
- * date formatting and parsing actions.
- * <P>
- * DateFormat helps you to format and parse dates for any locale. Your code can
- * be completely independent of the locale conventions for months, days of the
- * week, or even the calendar format: lunar vs. solar.
- * <P>
- * To format a date for the current Locale, use one of the static factory
- * methods:
- * <pre>
- * \code
- *      DateFormat* dfmt = DateFormat::createDateInstance();
- *      UDate myDate = Calendar::getNow();
- *      UnicodeString myString;
- *      myString = dfmt->format( myDate, myString );
- * \endcode
- * </pre>
- * If you are formatting multiple numbers, it is more efficient to get the
- * format and use it multiple times so that the system doesn't have to fetch the
- * information about the local language and country conventions multiple times.
- * <pre>
- * \code
- *      DateFormat* df = DateFormat::createDateInstance();
- *      UnicodeString myString;
- *      UDate myDateArr[] = { 0.0, 100000000.0, 2000000000.0 }; // test values
- *      for (int32_t i = 0; i < 3; ++i) {
- *          myString.remove();
- *          cout << df->format( myDateArr[i], myString ) << endl;
- *      }
- * \endcode
- * </pre>
- * To get specific fields of a date, you can use UFieldPosition to
- * get specific fields.
- * <pre>
- * \code
- *      DateFormat* dfmt = DateFormat::createDateInstance();
- *      FieldPosition pos(DateFormat::YEAR_FIELD);
- *      UnicodeString myString;
- *      myString = dfmt->format( myDate, myString );
- *      cout << myString << endl;
- *      cout << pos.getBeginIndex() << "," << pos. getEndIndex() << endl;
- * \endcode
- * </pre>
- * To format a date for a different Locale, specify it in the call to
- * createDateInstance().
- * <pre>
- * \code
- *       DateFormat* df =
- *           DateFormat::createDateInstance( DateFormat::SHORT, Locale::getFrance());
- * \endcode
- * </pre>
- * You can use a DateFormat to parse also.
- * <pre>
- * \code
- *       UErrorCode status = U_ZERO_ERROR;
- *       UDate myDate = df->parse(myString, status);
- * \endcode
- * </pre>
- * Use createDateInstance() to produce the normal date format for that country.
- * There are other static factory methods available. Use createTimeInstance()
- * to produce the normal time format for that country. Use createDateTimeInstance()
- * to produce a DateFormat that formats both date and time. You can pass in
- * different options to these factory methods to control the length of the
- * result; from SHORT to MEDIUM to LONG to FULL. The exact result depends on the
- * locale, but generally:
- * <ul type=round>
- *   <li>   SHORT is completely numeric, such as 12/13/52 or 3:30pm
- *   <li>   MEDIUM is longer, such as Jan 12, 1952
- *   <li>   LONG is longer, such as January 12, 1952 or 3:30:32pm
- *   <li>   FULL is pretty completely specified, such as
- *          Tuesday, April 12, 1952 AD or 3:30:42pm PST.
- * </ul>
- * You can also set the time zone on the format if you wish. If you want even
- * more control over the format or parsing, (or want to give your users more
- * control), you can try casting the DateFormat you get from the factory methods
- * to a SimpleDateFormat. This will work for the majority of countries; just
- * remember to chck getDynamicClassID() before carrying out the cast.
- * <P>
- * You can also use forms of the parse and format methods with ParsePosition and
- * FieldPosition to allow you to
- * <ul type=round>
- *   <li>   Progressively parse through pieces of a string.
- *   <li>   Align any particular field, or find out where it is for selection
- *          on the screen.
- * </ul>
- *
- * <p><em>User subclasses are not supported.</em> While clients may write
- * subclasses, such code will not necessarily work and will not be
- * guaranteed to work stably from release to release.

- * This class represents the set of symbols needed by DecimalFormat

- * of these symbols, you can get the DecimalFormatSymbols object from
- * your DecimalFormat and modify it.
- * <P>
- * Here are the special characters used in the parts of the
- * subpattern, with notes on their usage.
- * <pre>
- * \code
- *        Symbol   Meaning
- *          0      a digit
- *          #      a digit, zero shows as absent
- *          .      placeholder for decimal separator
- *          ,      placeholder for grouping separator.
- *          ;      separates formats.
- *          -      default negative prefix.
- *          %      divide by 100 and show as percentage
- *          X      any other characters can be used in the prefix or suffix
- *          '      used to quote special characters in a prefix or suffix.
- * \endcode
- *  </pre>
- * [Notes]
- * <P>
- * If there is no explicit negative subpattern, - is prefixed to the
- * positive form. That is, "0.00" alone is equivalent to "0.00;-0.00".
- * <P>
- * The grouping separator is commonly used for thousands, but in some
- * countries for ten-thousands. The interval is a constant number of
- * digits between the grouping characters, such as 100,000,000 or 1,0000,0000.
- * If you supply a pattern with multiple grouping characters, the interval
- * between the last one and the end of the integer is the one that is
- * used. So "#,##,###,####" == "######,####" == "##,####,####".

-/**
- * **IMPORTANT:** New users are strongly encouraged to see if
- * numberformatter.h fits their use case.  Although not deprecated, this header
- * is provided for backwards compatibility only.
- *
- * DecimalFormat is a concrete subclass of NumberFormat that formats decimal
- * numbers. It has a variety of features designed to make it possible to parse
- * and format numbers in any locale, including support for Western, Arabic, or
- * Indic digits.  It also supports different flavors of numbers, including
- * integers ("123"), fixed-point numbers ("123.4"), scientific notation
- * ("1.23E4"), percentages ("12%"), and currency amounts ("$123", "USD123",
- * "123 US dollars").  All of these flavors can be easily localized.
- *
- * To obtain a NumberFormat for a specific locale (including the default
- * locale) call one of NumberFormat's factory methods such as
- * createInstance(). Do not call the DecimalFormat constructors directly, unless
- * you know what you are doing, since the NumberFormat factory methods may
- * return subclasses other than DecimalFormat.
- *
- * **Example Usage**
- *
- * \code
- *     // Normally we would have a GUI with a menu for this
- *     int32_t locCount;
- *     const Locale* locales = NumberFormat::getAvailableLocales(locCount);
- *
- *     double myNumber = -1234.56;
- *     UErrorCode success = U_ZERO_ERROR;
- *     NumberFormat* form;
- *
- *     // Print out a number with the localized number, currency and percent
- *     // format for each locale.
- *     UnicodeString countryName;
- *     UnicodeString displayName;
- *     UnicodeString str;
- *     UnicodeString pattern;
- *     Formattable fmtable;
- *     for (int32_t j = 0; j < 3; ++j) {
- *         cout << endl << "FORMAT " << j << endl;
- *         for (int32_t i = 0; i < locCount; ++i) {
- *             if (locales[i].getCountry(countryName).size() == 0) {
- *                 // skip language-only
- *                 continue;
- *             }
- *             switch (j) {
- *             case 0:
- *                 form = NumberFormat::createInstance(locales[i], success ); break;
- *             case 1:
- *                 form = NumberFormat::createCurrencyInstance(locales[i], success ); break;
- *             default:
- *                 form = NumberFormat::createPercentInstance(locales[i], success ); break;
- *             }
- *             if (form) {
- *                 str.remove();
- *                 pattern = ((DecimalFormat*)form)->toPattern(pattern);

- * <p><strong>Patterns</strong>
- *
- * <p>A DecimalFormat consists of a <em>pattern</em> and a set of
- * <em>symbols</em>.  The pattern may be set directly using
- * applyPattern(), or indirectly using other API methods which
- * manipulate aspects of the pattern, such as the minimum number of integer
- * digits.  The symbols are stored in a DecimalFormatSymbols
- * object.  When using the NumberFormat factory methods, the
- * pattern and symbols are read from ICU's locale data.
- *
- * <p><strong>Special Pattern Characters</strong>
- *
- * <p>Many characters in a pattern are taken literally; they are matched during
- * parsing and output unchanged during formatting.  Special characters, on the
- * other hand, stand for other characters, strings, or classes of characters.
- * For example, the '#' character is replaced by a localized digit.  Often the
- * replacement character is the same as the pattern character; in the U.S. locale,
- * the ',' grouping character is replaced by ','.  However, the replacement is
- * still happening, and if the symbols are modified, the grouping character
- * changes.  Some special characters affect the behavior of the formatter by
- * their presence; for example, if the percent character is seen, then the
- * value is multiplied by 100 before being displayed.
- *
- * <p>To insert a special character in a pattern as a literal, that is, without
- * any special meaning, the character must be quoted.  There are some exceptions to
- * this which are noted below.
- *
- * <p>The characters listed here are used in non-localized patterns.  Localized
- * patterns use the corresponding characters taken from this formatter's
- * DecimalFormatSymbols object instead, and these characters lose
- * their special status.  Two exceptions are the currency sign and quote, which
- * are not localized.

- *
- * <p>A DecimalFormat pattern contains a positive and negative
- * subpattern, for example, "#,##0.00;(#,##0.00)".  Each subpattern has a
- * prefix, a numeric part, and a suffix.  If there is no explicit negative
- * subpattern, the negative subpattern is the localized minus sign prefixed to the
- * positive subpattern. That is, "0.00" alone is equivalent to "0.00;-0.00".  If there
- * is an explicit negative subpattern, it serves only to specify the negative
- * prefix and suffix; the number of digits, minimal digits, and other
- * characteristics are ignored in the negative subpattern. That means that
- * "#,##0.0#;(#)" has precisely the same result as "#,##0.0#;(#,##0.0#)".
- *
- * <p>The prefixes, suffixes, and various symbols used for infinity, digits,
- * thousands separators, decimal separators, etc. may be set to arbitrary
- * values, and they will appear properly during formatting.  However, care must
- * be taken that the symbols and strings do not conflict, or parsing will be
- * unreliable.  For example, either the positive and negative prefixes or the
- * suffixes must be distinct for parse() to be able
- * to distinguish positive from negative values.  Another example is that the
- * decimal separator and thousands separator should be distinct characters, or
- * parsing will be impossible.
- *
- * <p>The <em>grouping separator</em> is a character that separates clusters of
- * integer digits to make large numbers more legible.  It commonly used for
- * thousands, but in some locales it separates ten-thousands.  The <em>grouping
- * size</em> is the number of digits between the grouping separators, such as 3
- * for "100,000,000" or 4 for "1 0000 0000". There are actually two different
- * grouping sizes: One used for the least significant integer digits, the
- * <em>primary grouping size</em>, and one used for all others, the
- * <em>secondary grouping size</em>.  In most locales these are the same, but
- * sometimes they are different. For example, if the primary grouping interval
- * is 3, and the secondary is 2, then this corresponds to the pattern
- * "#,##,##0", and the number 123456789 is formatted as "12,34,56,789".  If a
- * pattern contains multiple grouping separators, the interval between the last
- * one and the end of the integer defines the primary grouping size, and the
- * interval between the last two defines the secondary grouping size. All others
- * are ignored, so "#,##,###,####" == "###,###,####" == "##,#,###,####".
- *
- * <p>Illegal patterns, such as "#.#.#" or "#.###,###", will cause
- * DecimalFormat to set a failing UErrorCode.

- * sigDigits elements, between any two pattern characters of that
- * element, as long as the integer or sigDigits element is not
- * followed by the exponent element.
- *
- * <li>Two grouping intervals are recognized: That between the
- *     decimal point and the first grouping symbol, and that
- *     between the first and second grouping symbols. These
- *     intervals are identical in most locales, but in some
- *     locales they differ. For example, the pattern
- *     &quot;#,##,###&quot; formats the number 123456789 as
- *     &quot;12,34,56,789&quot;.</li>
- *
- * <li>The pad specifier <code>padSpec</code> may appear before the prefix,

- *
- * <li>In place of '0', the digits '1' through '9' may be used to
- * indicate a rounding increment.
- * </ul>
- *
- * <p><strong>Parsing</strong>
- *
- * <p>DecimalFormat parses all Unicode characters that represent
- * decimal digits, as defined by u_charDigitValue().  In addition,
- * DecimalFormat also recognizes as digits the ten consecutive
- * characters starting with the localized zero digit defined in the
- * DecimalFormatSymbols object.  During formatting, the
- * DecimalFormatSymbols-based digits are output.
- *
- * <p>During parsing, grouping separators are ignored if in lenient mode;
- * otherwise, if present, they must be in appropriate positions.
- *
- * <p>For currency parsing, the formatter is able to parse every currency
- * style formats no matter which style the formatter is constructed with.
- * For example, a formatter instance gotten from
- * NumberFormat.getInstance(ULocale, NumberFormat.CURRENCYSTYLE) can parse
- * formats such as "USD1.00" and "3.00 US dollars".
- *
- * <p>If parse(UnicodeString&,Formattable&,ParsePosition&)
- * fails to parse a string, it leaves the parse position unchanged.
- * The convenience method parse(UnicodeString&,Formattable&,UErrorCode&)
- * indicates parse failure by setting a failing
- * UErrorCode.
- *
- * <p><strong>Formatting</strong>
- *
- * <p>Formatting is guided by several parameters, all of which can be
- * specified either using a pattern or using the API.  The following
- * description applies to formats that do not use <a href="#sci">scientific
- * notation</a> or <a href="#sigdig">significant digits</a>.
- *
- * <ul><li>If the number of actual integer digits exceeds the
- * <em>maximum integer digits</em>, then only the least significant
- * digits are shown.  For example, 1997 is formatted as "97" if the
- * maximum integer digits is set to 2.
- *
- * <li>If the number of actual integer digits is less than the
- * <em>minimum integer digits</em>, then leading zeros are added.  For
- * example, 1997 is formatted as "01997" if the minimum integer digits
- * is set to 5.
- *
- * <li>If the number of actual fraction digits exceeds the <em>maximum
- * fraction digits</em>, then rounding is performed to the
- * maximum fraction digits.  For example, 0.125 is formatted as "0.12"
- * if the maximum fraction digits is 2.  This behavior can be changed
- * by specifying a rounding increment and/or a rounding mode.
- *
- * <li>If the number of actual fraction digits is less than the
- * <em>minimum fraction digits</em>, then trailing zeros are added.
- * For example, 0.125 is formatted as "0.1250" if the minimum fraction
- * digits is set to 4.
- *
- * <li>Trailing fractional zeros are not displayed if they occur
- * <em>j</em> positions after the decimal, where <em>j</em> is less
- * than the maximum fraction digits. For example, 0.10004 is
- * formatted as "0.1" if the maximum fraction digits is four or less.
- * </ul>
- *
- * <p><strong>Special Values</strong>
- *
- * <p><code>NaN</code> is represented as a single character, typically
- * <code>\\uFFFD</code>.  This character is determined by the
- * DecimalFormatSymbols object.  This is the only value for which
- * the prefixes and suffixes are not used.
- *
- * <p>Infinity is represented as a single character, typically
- * <code>\\u221E</code>, with the positive or negative prefixes and suffixes
- * applied.  The infinity character is determined by the
- * DecimalFormatSymbols object.
- *
- * <a name="sci"><strong>Scientific Notation</strong></a>
- *
- * <p>Numbers in scientific notation are expressed as the product of a mantissa
- * and a power of ten, for example, 1234 can be expressed as 1.234 x 10<sup>3</sup>. The
- * mantissa is typically in the half-open interval [1.0, 10.0) or sometimes [0.0, 1.0),
- * but it need not be.  DecimalFormat supports arbitrary mantissas.
- * DecimalFormat can be instructed to use scientific
- * notation through the API or through the pattern.  In a pattern, the exponent
- * character immediately followed by one or more digit characters indicates
- * scientific notation.  Example: "0.###E0" formats the number 1234 as
- * "1.234E3".
- *
- * <ul>
- * <li>The number of digit characters after the exponent character gives the
- * minimum exponent digit count.  There is no maximum.  Negative exponents are
- * formatted using the localized minus sign, <em>not</em> the prefix and suffix
- * from the pattern.  This allows patterns such as "0.###E0 m/s".  To prefix
- * positive exponents with a localized plus sign, specify '+' between the
- * exponent and the digits: "0.###E+0" will produce formats "1E+1", "1E+0",
- * "1E-1", etc.  (In localized patterns, use the localized plus sign rather than
- * '+'.)
- *
- * <li>The minimum number of integer digits is achieved by adjusting the
- * exponent.  Example: 0.00123 formatted with "00.###E0" yields "12.3E-4".  This
- * only happens if there is no maximum number of integer digits.  If there is a
- * maximum, then the minimum number of integer digits is fixed at one.
- *
- * <li>The maximum number of integer digits, if present, specifies the exponent
- * grouping.  The most common use of this is to generate <em>engineering
- * notation</em>, in which the exponent is a multiple of three, e.g.,
- * "##0.###E0".  The number 12345 is formatted using "##0.####E0" as "12.345E3".
- *
- * <li>When using scientific notation, the formatter controls the
- * digit counts using significant digits logic.  The maximum number of
- * significant digits limits the total number of integer and fraction
- * digits that will be shown in the mantissa; it does not affect
- * parsing.  For example, 12345 formatted with "##0.##E0" is "12.3E3".
- * See the section on significant digits for more details.
- *
- * <li>The number of significant digits shown is determined as
- * follows: If areSignificantDigitsUsed() returns false, then the
- * minimum number of significant digits shown is one, and the maximum
- * number of significant digits shown is the sum of the <em>minimum
- * integer</em> and <em>maximum fraction</em> digits, and is
- * unaffected by the maximum integer digits.  If this sum is zero,
- * then all significant digits are shown.  If
- * areSignificantDigitsUsed() returns true, then the significant digit
- * counts are specified by getMinimumSignificantDigits() and
- * getMaximumSignificantDigits().  In this case, the number of
- * integer digits is fixed at one, and there is no exponent grouping.
- *
- * <li>Exponential patterns may not contain grouping separators.
- * </ul>
- *
- * <a name="sigdig"><strong>Significant Digits</strong></a>
- *
- * <code>DecimalFormat</code> has two ways of controlling how many
- * digits are shows: (a) significant digits counts, or (b) integer and
- * fraction digit counts.  Integer and fraction digit counts are
- * described above.  When a formatter is using significant digits
- * counts, the number of integer and fraction digits is not specified
- * directly, and the formatter settings for these counts are ignored.
- * Instead, the formatter uses however many integer and fraction
- * digits are required to display the specified number of significant
- * digits.  Examples:
- *
- * <table border=0 cellspacing=3 cellpadding=0>
- *   <tr bgcolor="#ccccff">
- *     <td align=left>Pattern

- *     <td><code>1.23</code>
- * </table>
- *
- * <ul>
- * <li>Significant digit counts may be expressed using patterns that
- * specify a minimum and maximum number of significant digits.  These
- * are indicated by the <code>'@'</code> and <code>'#'</code>
- * characters.  The minimum number of significant digits is the number
- * of <code>'@'</code> characters.  The maximum number of significant
- * digits is the number of <code>'@'</code> characters plus the number
- * of <code>'#'</code> characters following on the right.  For
- * example, the pattern <code>"@@@"</code> indicates exactly 3
- * significant digits.  The pattern <code>"@##"</code> indicates from
- * 1 to 3 significant digits.  Trailing zero digits to the right of
- * the decimal separator are suppressed after the minimum number of
- * significant digits have been shown.  For example, the pattern
- * <code>"@##"</code> formats the number 0.1203 as
- * <code>"0.12"</code>.
- *
- * <li>If a pattern uses significant digits, it may not contain a
- * decimal separator, nor the <code>'0'</code> pattern character.
- * Patterns such as <code>"@00"</code> or <code>"@.###"</code> are
- * disallowed.
- *
- * <li>Any number of <code>'#'</code> characters may be prepended to
- * the left of the leftmost <code>'@'</code> character.  These have no
- * effect on the minimum and maximum significant digits counts, but
- * may be used to position grouping separators.  For example,
- * <code>"#,#@#"</code> indicates a minimum of one significant digits,
- * a maximum of two significant digits, and a grouping size of three.
- *
- * <li>In order to enable significant digits formatting, use a pattern
- * containing the <code>'@'</code> pattern character.  Alternatively,
- * call setSignificantDigitsUsed(TRUE).
- *
- * <li>In order to disable significant digits formatting, use a
- * pattern that does not contain the <code>'@'</code> pattern
- * character. Alternatively, call setSignificantDigitsUsed(FALSE).
- *
- * <li>The number of significant digits has no effect on parsing.
- *
- * <li>Significant digits may be used together with exponential notation. Such
- * patterns are equivalent to a normal exponential pattern with a minimum and
- * maximum integer digit count of one, a minimum fraction digit count of
- * <code>getMinimumSignificantDigits() - 1</code>, and a maximum fraction digit
- * count of <code>getMaximumSignificantDigits() - 1</code>. For example, the
- * pattern <code>"@@###E0"</code> is equivalent to <code>"0.0###E0"</code>.
- *
- * <li>If significant digits are in use, then the integer and fraction
- * digit counts, as set via the API, are ignored.  If significant
- * digits are not in use, then the significant digit counts, as set via
- * the API, are ignored.
- *
- * </ul>
- *
- * <p><strong>Padding</strong>
- *
- * <p>DecimalFormat supports padding the result of
- * format() to a specific width.  Padding may be specified either
- * through the API or through the pattern syntax.  In a pattern the pad escape
- * character, followed by a single pad character, causes padding to be parsed
- * and formatted.  The pad escape character is '*' in unlocalized patterns, and
- * can be localized using DecimalFormatSymbols::setSymbol() with a
- * DecimalFormatSymbols::kPadEscapeSymbol
- * selector.  For example, <code>"$*x#,##0.00"</code> formats 123 to
- * <code>"$xx123.00"</code>, and 1234 to <code>"$1,234.00"</code>.
- *
- * <ul>
- * <li>When padding is in effect, the width of the positive subpattern,
- * including prefix and suffix, determines the format width.  For example, in
- * the pattern <code>"* #0 o''clock"</code>, the format width is 10.
- *
- * <li>The width is counted in 16-bit code units (char16_ts).
- *
- * <li>Some parameters which usually do not matter have meaning when padding is
- * used, because the pattern width is significant with padding.  In the pattern
- * "* ##,##,#,##0.##", the format width is 14.  The initial characters "##,##,"
- * do not affect the grouping size or maximum integer digits, but they do affect
- * the format width.
- *
- * <li>Padding may be inserted at one of four locations: before the prefix,
- * after the prefix, before the suffix, or after the suffix.  If padding is
- * specified in any other location, applyPattern()
- * sets a failing UErrorCode.  If there is no prefix,
- * before the prefix and after the prefix are equivalent, likewise for the
- * suffix.
- *
- * <li>When specified in a pattern, the 32-bit code point immediately
- * following the pad escape is the pad character. This may be any character,
- * including a special pattern character. That is, the pad escape
- * <em>escapes</em> the following character. If there is no character after
- * the pad escape, then the pattern is illegal.
- *
- * </ul>
- *
- * <p><strong>Rounding</strong>
- *
- * <p>DecimalFormat supports rounding to a specific increment.  For
- * example, 1230 rounded to the nearest 50 is 1250.  1.234 rounded to the
- * nearest 0.65 is 1.3.  The rounding increment may be specified through the API
- * or in a pattern.  To specify a rounding increment in a pattern, include the
- * increment in the pattern itself.  "#,#50" specifies a rounding increment of
- * 50.  "#,##0.05" specifies a rounding increment of 0.05.
- *
- * <p>In the absence of an explicit rounding increment numbers are
- * rounded to their formatted width.
- *
- * <ul>
- * <li>Rounding only affects the string produced by formatting.  It does
- * not affect parsing or change any numerical values.
- *
- * <li>A <em>rounding mode</em> determines how values are rounded; see
- * DecimalFormat::ERoundingMode.  The default rounding mode is
- * DecimalFormat::kRoundHalfEven.  The rounding mode can only be set
- * through the API; it can not be set with a pattern.
- *
- * <li>Some locales use rounding in their currency formats to reflect the
- * smallest currency denomination.
- *
- * <li>In a pattern, digits '1' through '9' specify rounding, but otherwise
- * behave identically to digit '0'.
- * </ul>
- *
- * <p><strong>Synchronization</strong>

-/**
- * DateFormatSymbols is a public class for encapsulating localizable date-time
- * formatting data -- including timezone data. DateFormatSymbols is used by
- * DateFormat and SimpleDateFormat.
- * <P>
- * Rather than first creating a DateFormatSymbols to get a date-time formatter
- * by using a SimpleDateFormat constructor, clients are encouraged to create a
- * date-time formatter using the getTimeInstance(), getDateInstance(), or
- * getDateTimeInstance() method in DateFormat. Each of these methods can return a
- * date/time formatter initialized with a default format pattern along with the
- * date-time formatting data for a given or default locale. After a formatter is
- * created, clients may modify the format pattern using the setPattern function
- * as so desired. For more information on using these formatter factory
- * functions, see DateFormat.
- * <P>
- * If clients decide to create a date-time formatter with a particular format
- * pattern and locale, they can do so with new SimpleDateFormat(aPattern,
- * new DateFormatSymbols(aLocale)).  This will load the appropriate date-time
- * formatting data from the locale.
- * <P>
- * DateFormatSymbols objects are clonable. When clients obtain a
- * DateFormatSymbols object, they can feel free to modify the date-time
- * formatting data as necessary. For instance, clients can
- * replace the localized date-time format pattern characters with the ones that
- * they feel easy to remember. Or they can change the representative cities
- * originally picked by default to using their favorite ones.
- * <P>
- * DateFormatSymbols are not expected to be subclassed. Data for a calendar is
- * loaded out of resource bundles.  The 'type' parameter indicates the type of
- * calendar, for example, "gregorian" or "japanese".  If the type is not gregorian
- * (or NULL, or an empty string) then the type is appended to the resource name,
- * for example,  'Eras_japanese' instead of 'Eras'.   If the resource 'Eras_japanese' did
- * not exist (even in root), then this class will fall back to just 'Eras', that is,
- * Gregorian data.  Therefore, the calendar implementor MUST ensure that the root
- * locale at least contains any resources that are to be particularized for the
- * calendar type.

-/**
- * DateIntervalFormat is a class for formatting and parsing date
- * intervals in a language-independent manner.
- * Only formatting is supported, parsing is not supported.
- *
- * <P>
- * Date interval means from one date to another date,
- * for example, from "Jan 11, 2008" to "Jan 18, 2008".
- * We introduced class DateInterval to represent it.
- * DateInterval is a pair of UDate, which is
- * the standard milliseconds since 24:00 GMT, Jan 1, 1970.
- *
- * <P>
- * DateIntervalFormat formats a DateInterval into
- * text as compactly as possible.
- * For example, the date interval format from "Jan 11, 2008" to "Jan 18,. 2008"
- * is "Jan 11-18, 2008" for English.
- * And it parses text into DateInterval,
- * although initially, parsing is not supported.
- *
- * <P>
- * There is no structural information in date time patterns.
- * For any punctuations and string literals inside a date time pattern,
- * we do not know whether it is just a separator, or a prefix, or a suffix.
- * Without such information, so, it is difficult to generate a sub-pattern
- * (or super-pattern) by algorithm.
- * So, formatting a DateInterval is pattern-driven. It is very
- * similar to formatting in SimpleDateFormat.
- * We introduce class DateIntervalInfo to save date interval
- * patterns, similar to date time pattern in SimpleDateFormat.
- *
- * <P>
- * Logically, the interval patterns are mappings
- * from (skeleton, the_largest_different_calendar_field)
- * to (date_interval_pattern).
- *
- * <P>
- * A skeleton
- * <ol>
- * <li>
- * only keeps the field pattern letter and ignores all other parts
- * in a pattern, such as space, punctuations, and string literals.
- * </li>
- * <li>
- * hides the order of fields.
- * </li>
- * <li>
- * might hide a field's pattern letter length.
- * </li>
- * </ol>
- *
- * For those non-digit calendar fields, the pattern letter length is
- * important, such as MMM, MMMM, and MMMMM; EEE and EEEE,
- * and the field's pattern letter length is honored.
- *
- * For the digit calendar fields,  such as M or MM, d or dd, yy or yyyy,
- * the field pattern length is ignored and the best match, which is defined
- * in date time patterns, will be returned without honor the field pattern
- * letter length in skeleton.
- *
- * <P>
- * The calendar fields we support for interval formatting are:
- * year, month, date, day-of-week, am-pm, hour, hour-of-day, minute, second,
- * and millisecond.
- * (though we do not currently have specific intervalFormat date for skeletons
- * with seconds and millisecond).
- * Those calendar fields can be defined in the following order:
- * year >  month > date > hour (in day) >  minute > second > millisecond
- *
- * The largest different calendar fields between 2 calendars is the
- * first different calendar field in above order.
- *
- * For example: the largest different calendar fields between "Jan 10, 2007"
- * and "Feb 20, 2008" is year.
- *
- * <P>
- * For other calendar fields, the compact interval formatting is not
- * supported. And the interval format will be fall back to fall-back
- * patterns, which is mostly "{date0} - {date1}".
- *
- * <P>
- * There is a set of pre-defined static skeleton strings.
- * There are pre-defined interval patterns for those pre-defined skeletons
- * in locales' resource files.
- * For example, for a skeleton UDAT_YEAR_ABBR_MONTH_DAY, which is  &quot;yMMMd&quot;,
- * in  en_US, if the largest different calendar field between date1 and date2
- * is &quot;year&quot;, the date interval pattern  is &quot;MMM d, yyyy - MMM d, yyyy&quot;,
- * such as &quot;Jan 10, 2007 - Jan 10, 2008&quot;.
- * If the largest different calendar field between date1 and date2 is &quot;month&quot;,
- * the date interval pattern is &quot;MMM d - MMM d, yyyy&quot;,
- * such as &quot;Jan 10 - Feb 10, 2007&quot;.
- * If the largest different calendar field between date1 and date2 is &quot;day&quot;,
- * the date interval pattern is &quot;MMM d-d, yyyy&quot;, such as &quot;Jan 10-20, 2007&quot;.
- *
- * For date skeleton, the interval patterns when year, or month, or date is
- * different are defined in resource files.
- * For time skeleton, the interval patterns when am/pm, or hour, or minute is
- * different are defined in resource files.
- *
- * <P>
- * If a skeleton is not found in a locale's DateIntervalInfo, which means
- * the interval patterns for the skeleton is not defined in resource file,
- * the interval pattern will falls back to the interval "fallback" pattern
- * defined in resource file.
- * If the interval "fallback" pattern is not defined, the default fall-back
- * is "{date0} - {data1}".
- *
- * <P>
- * For the combination of date and time,
- * The rule to generate interval patterns are:
- * <ol>
- * <li>
- *    when the year, month, or day differs, falls back to fall-back
- *    interval pattern, which mostly is the concatenate the two original
- *    expressions with a separator between,
- *    For example, interval pattern from "Jan 10, 2007 10:10 am"
- *    to "Jan 11, 2007 10:10am" is
- *    "Jan 10, 2007 10:10 am - Jan 11, 2007 10:10am"
- * </li>
- * <li>
- *    otherwise, present the date followed by the range expression
- *    for the time.
- *    For example, interval pattern from "Jan 10, 2007 10:10 am"
- *    to "Jan 10, 2007 11:10am" is "Jan 10, 2007 10:10 am - 11:10am"
- * </li>
- * </ol>
- *
- *
- * <P>
- * If two dates are the same, the interval pattern is the single date pattern.
- * For example, interval pattern from "Jan 10, 2007" to "Jan 10, 2007" is
- * "Jan 10, 2007".
- *
- * Or if the presenting fields between 2 dates have the exact same values,
- * the interval pattern is the  single date pattern.
- * For example, if user only requests year and month,
- * the interval pattern from "Jan 10, 2007" to "Jan 20, 2007" is "Jan 2007".
- *
- * <P>
- * DateIntervalFormat needs the following information for correct
- * formatting: time zone, calendar type, pattern, date format symbols,
- * and date interval patterns.
- * It can be instantiated in 2 ways:
- * <ol>
- * <li>
- *    create an instance using default or given locale plus given skeleton.
- *    Users are encouraged to created date interval formatter this way and
- *    to use the pre-defined skeleton macros, such as
- *    UDAT_YEAR_NUM_MONTH, which consists the calendar fields and
- *    the format style.
- * </li>
- * <li>
- *    create an instance using default or given locale plus given skeleton
- *    plus a given DateIntervalInfo.
- *    This factory method is for powerful users who want to provide their own
- *    interval patterns.
- *    Locale provides the timezone, calendar, and format symbols information.
- *    Local plus skeleton provides full pattern information.
- *    DateIntervalInfo provides the date interval patterns.
- * </li>
- * </ol>
- *
- * <P>
- * For the calendar field pattern letter, such as G, y, M, d, a, h, H, m, s etc.
- * DateIntervalFormat uses the same syntax as that of
- * DateTime format.
- *
- * <P>
- * Code Sample: general usage
- * <pre>
- * \code
- *   // the date interval object which the DateIntervalFormat formats on
- *   // and parses into
- *   DateInterval*  dtInterval = new DateInterval(1000*3600*24, 1000*3600*24*2);
- *   UErrorCode status = U_ZERO_ERROR;
- *   DateIntervalFormat* dtIntervalFmt = DateIntervalFormat::createInstance(
- *                           UDAT_YEAR_MONTH_DAY,

- *   UnicodeUnicodeString dateIntervalString;
- *   FieldPosition pos = 0;

-/**
- * DateIntervalInfo is a public class for encapsulating localizable
- * date time interval patterns. It is used by DateIntervalFormat.
- *
- * <P>
- * For most users, ordinary use of DateIntervalFormat does not need to create
- * DateIntervalInfo object directly.
- * DateIntervalFormat will take care of it when creating a date interval
- * formatter when user pass in skeleton and locale.
- *
- * <P>
- * For power users, who want to create their own date interval patterns,
- * or want to re-set date interval patterns, they could do so by
- * directly creating DateIntervalInfo and manupulating it.
- *
- * <P>
- * Logically, the interval patterns are mappings
- * from (skeleton, the_largest_different_calendar_field)
- * to (date_interval_pattern).
- *
- * <P>
- * A skeleton
- * <ol>
- * <li>
- * only keeps the field pattern letter and ignores all other parts
- * in a pattern, such as space, punctuations, and string literals.
- * <li>
- * hides the order of fields.
- * <li>
- * might hide a field's pattern letter length.
- *
- * For those non-digit calendar fields, the pattern letter length is
- * important, such as MMM, MMMM, and MMMMM; EEE and EEEE,
- * and the field's pattern letter length is honored.
- *
- * For the digit calendar fields,  such as M or MM, d or dd, yy or yyyy,
- * the field pattern length is ignored and the best match, which is defined
- * in date time patterns, will be returned without honor the field pattern
- * letter length in skeleton.
- * </ol>
- *
- * <P>
- * The calendar fields we support for interval formatting are:
- * year, month, date, day-of-week, am-pm, hour, hour-of-day, and minute.
- * Those calendar fields can be defined in the following order:
- * year >  month > date > am-pm > hour >  minute
- *
- * The largest different calendar fields between 2 calendars is the
- * first different calendar field in above order.
- *
- * For example: the largest different calendar fields between &quot;Jan 10, 2007&quot;
- * and &quot;Feb 20, 2008&quot; is year.
- *
- * <P>
- * There is a set of pre-defined static skeleton strings.
- * There are pre-defined interval patterns for those pre-defined skeletons
- * in locales' resource files.
- * For example, for a skeleton UDAT_YEAR_ABBR_MONTH_DAY, which is  &quot;yMMMd&quot;,
- * in  en_US, if the largest different calendar field between date1 and date2
- * is &quot;year&quot;, the date interval pattern  is &quot;MMM d, yyyy - MMM d, yyyy&quot;,
- * such as &quot;Jan 10, 2007 - Jan 10, 2008&quot;.
- * If the largest different calendar field between date1 and date2 is &quot;month&quot;,
- * the date interval pattern is &quot;MMM d - MMM d, yyyy&quot;,
- * such as &quot;Jan 10 - Feb 10, 2007&quot;.
- * If the largest different calendar field between date1 and date2 is &quot;day&quot;,
- * the date interval pattern is &quot;MMM d-d, yyyy&quot;, such as &quot;Jan 10-20, 2007&quot;.
- *
- * For date skeleton, the interval patterns when year, or month, or date is
- * different are defined in resource files.
- * For time skeleton, the interval patterns when am/pm, or hour, or minute is
- * different are defined in resource files.
- *
- *
- * <P>
- * There are 2 dates in interval pattern. For most locales, the first date
- * in an interval pattern is the earlier date. There might be a locale in which
- * the first date in an interval pattern is the later date.
- * We use fallback format for the default order for the locale.
- * For example, if the fallback format is &quot;{0} - {1}&quot;, it means
- * the first date in the interval pattern for this locale is earlier date.
- * If the fallback format is &quot;{1} - {0}&quot;, it means the first date is the
- * later date.
- * For a particular interval pattern, the default order can be overriden
- * by prefixing &quot;latestFirst:&quot; or &quot;earliestFirst:&quot; to the interval pattern.
- * For example, if the fallback format is &quot;{0}-{1}&quot;,
- * but for skeleton &quot;yMMMd&quot;, the interval pattern when day is different is
- * &quot;latestFirst:d-d MMM yy&quot;, it means by default, the first date in interval
- * pattern is the earlier date. But for skeleton &quot;yMMMd&quot;, when day is different,
- * the first date in &quot;d-d MMM yy&quot; is the later date.
- *
- * <P>
- * The recommended way to create a DateIntervalFormat object is to pass in
- * the locale.
- * By using a Locale parameter, the DateIntervalFormat object is
- * initialized with the pre-defined interval patterns for a given or
- * default locale.
- * <P>
- * Users can also create DateIntervalFormat object
- * by supplying their own interval patterns.
- * It provides flexibility for power users.
- *
- * <P>
- * After a DateIntervalInfo object is created, clients may modify
- * the interval patterns using setIntervalPattern function as so desired.
- * Currently, users can only set interval patterns when the following
- * calendar fields are different: ERA, YEAR, MONTH, DATE, DAY_OF_MONTH,
- * DAY_OF_WEEK, AM_PM, HOUR, HOUR_OF_DAY, MINUTE, SECOND, and MILLISECOND.
- * Interval patterns when other calendar fields are different is not supported.
- * <P>
- * DateIntervalInfo objects are cloneable.
- * When clients obtain a DateIntervalInfo object,
- * they can feel free to modify it as necessary.
- * <P>
- * DateIntervalInfo are not expected to be subclassed.
- * Data for a calendar is loaded out of resource bundles.
- * Through ICU 4.4, date interval patterns are only supported in the Gregorian
- * calendar; non-Gregorian calendars are supported from ICU 4.4.1.

- * is done, a query can be made using a "skeleton", which is a pattern which just
- * includes the desired fields and lengths. The generator will return the "best fit"
- * pattern corresponding to that skeleton.
- * <p>The main method people will use is getBestPattern(String skeleton),
- * since normally this class is pre-built with data from a particular locale.
- * However, generators can be built directly from other data as well.
- * <p><i>Issue: may be useful to also have a function that returns the list of
- * fields in a pattern, in order, since we have that internally.
- * That would be useful for getting the UI order of field elements.</i>

- *
- * There are two types of edits: <em>change edits</em> and <em>no-change edits</em>. Add edits to
- * instances of this class using {@link #addReplace(int32_t, int32_t)} (for change edits) and
- * {@link #addUnchanged(int32_t)} (for no-change edits). Change edits are retained with full granularity,

- *
- * After all edits have been added, instances of this class should be considered immutable, and an

- *
- * <ul>

- * <li>{@link #getFineChangesIterator()} retains full granularity of change edits, and when calling

- * </ul>
- *
- * For example, consider the string "abcßDeF", which case-folds to "abcssdef". This string has the
- * following fine edits:
- * <ul>
- * <li>abc ⇨ abc (no-change)
- * <li>ß ⇨ ss (change)
- * <li>D ⇨ d (change)
- * <li>e ⇨ e (no-change)
- * <li>F ⇨ f (change)
- * </ul>
- * and the following coarse edits (note how adjacent change edits get merged together):
- * <ul>
- * <li>abc ⇨ abc (no-change)
- * <li>ßD ⇨ ssd (change)
- * <li>e ⇨ e (no-change)
- * <li>F ⇨ f (change)
- * </ul>
- *
- * The "fine changes" and "coarse changes" iterators will step through only the change edits when their
- * `Edits::Iterator::next()` methods are called. They are identical to the non-change iterators when
- * their `Edits::Iterator::findSourceIndex()` or `Edits::Iterator::findDestinationIndex()`
- * methods are used to walk through the string.
- *
- * For examples of how to use this class, see the test `TestCaseMapEditsIteratorDocs` in
- * UCharacterCaseTest.java.
- *
- * An Edits object tracks a separate UErrorCode, but ICU string transformation functions
- * (e.g., case mapping functions) merge any such errors into their API's UErrorCode.

-/**
- * Wrapper class for UErrorCode, with conversion operators for direct use
- * in ICU C and C++ APIs.
- * Intended to be used as a base class, where a subclass overrides
- * the handleFailure() function so that it throws an exception,
- * does an assert(), logs an error, etc.
- * This is not an abstract base class. This class can be used and instantiated
- * by itself, although it will be more useful when subclassed.
- *
- * Features:
- * - The constructor initializes the internal UErrorCode to U_ZERO_ERROR,
- *   removing one common source of errors.
- * - Same use in C APIs taking a UErrorCode * (pointer)
- *   and C++ taking UErrorCode & (reference) via conversion operators.
- * - Possible automatic checking for success when it goes out of scope.
- *
- * Note: For automatic checking for success in the destructor, a subclass
- * must implement such logic in its own destructor because the base class
- * destructor cannot call a subclass function (like handleFailure()).
- * The ErrorCode base class destructor does nothing.
- *
- * Note also: While it is possible for a destructor to throw an exception,
- * it is generally unsafe to do so. This means that in a subclass the destructor
- * and the handleFailure() function may need to take different actions.
- *
- * Sample code:
- * \code
- *   class IcuErrorCode: public icu::ErrorCode {
- *   public:
- *     virtual ~IcuErrorCode() {  // should be defined in .cpp as "key function"
- *       // Safe because our handleFailure() does not throw exceptions.
- *       if(isFailure()) { handleFailure(); }
- *     }
- *   protected:
- *     virtual void handleFailure() const {
- *       log_failure(u_errorName(errorCode));
- *       exit(errorCode);
- *     }
- *   };
- *   IcuErrorCode error_code;
- *   UConverter *cnv = ucnv_open("Shift-JIS", error_code);
- *   length = ucnv_fromUChars(dest, capacity, src, length, error_code);
- *   ucnv_close(cnv);
- *   // IcuErrorCode destructor checks for success.
- * \endcode

-/**
- * <code>FieldPosition</code> is a simple class used by <code>Format</code>
- * and its subclasses to identify fields in formatted output. Fields are
- * identified by constants, whose names typically end with <code>_FIELD</code>,
- * defined in the various subclasses of <code>Format</code>. See
- * <code>ERA_FIELD</code> and its friends in <code>DateFormat</code> for
- * an example.
- *
- * <p>
- * <code>FieldPosition</code> keeps track of the position of the
- * field within the formatted output with two indices: the index
- * of the first character of the field and the index of the last
- * character of the field.
- *
- * <p>
- * One version of the <code>format</code> method in the various
- * <code>Format</code> classes requires a <code>FieldPosition</code>
- * object as an argument. You use this <code>format</code> method
- * to perform partial formatting or to get information about the
- * formatted output (such as the position of a field).
- *
- * The FieldPosition class is not intended for public subclassing.
- *
- * <p>
- * Below is an example of using <code>FieldPosition</code> to aid
- * alignment of an array of formatted floating-point numbers on
- * their decimal points:
- * <pre>
- * \code
- *       double doubleNum[] = {123456789.0, -12345678.9, 1234567.89, -123456.789,
- *                  12345.6789, -1234.56789, 123.456789, -12.3456789, 1.23456789};
- *       int dNumSize = (int)(sizeof(doubleNum)/sizeof(double));
- *       
- *       UErrorCode status = U_ZERO_ERROR;
- *       DecimalFormat* fmt = (DecimalFormat*) NumberFormat::createInstance(status);
- *       fmt->setDecimalSeparatorAlwaysShown(true);
- *       
- *       const int tempLen = 20;
- *       char temp[tempLen];
- *       
- *       for (int i=0; i<dNumSize; i++) {
- *           FieldPosition pos(NumberFormat::INTEGER_FIELD);
- *           UnicodeString buf;
- *           char fmtText[tempLen];
- *           ToCharString(fmt->format(doubleNum[i], buf, pos), fmtText);
- *           for (int j=0; j<tempLen; j++) temp[j] = ' '; // clear with spaces
- *           temp[__min(tempLen, tempLen-pos.getEndIndex())] = '\0';
- *           cout << temp << fmtText   << endl;
- *       }
- *       delete fmt;
- * \endcode
- * </pre>
- * <p>
- * The code will generate the following output:
- * <pre>
- * \code
- *           123,456,789.000
- *           -12,345,678.900
- *             1,234,567.880

-/**
- * Formattable objects can be passed to the Format class or
- * its subclasses for formatting.  Formattable is a thin wrapper
- * class which interconverts between the primitive numeric types
- * (double, long, etc.) as well as UDate and UnicodeString.
- *
- * <p>Internally, a Formattable object is a union of primitive types.
- * As such, it can only store one flavor of data at a time.  To
- * determine what flavor of data it contains, use the getType method.
- *
- * <p>As of ICU 3.0, Formattable may also wrap a UObject pointer,
- * which it owns.  This allows an instance of any ICU class to be
- * encapsulated in a Formattable.  For legacy reasons and for
- * efficiency, primitive numeric types are still stored directly
- * within a Formattable.
- *
- * <p>The Formattable class is not suitable for subclassing.
- *
- * <p>See UFormattable for a C wrapper.

-/**
- * Base class for all formats.  This is an abstract base class which
- * specifies the protocol for classes which convert other objects or
- * values, such as numeric values and dates, and their string
- * representations.  In some cases these representations may be
- * localized or contain localized characters or strings.  For example,
- * a numeric formatter such as DecimalFormat may convert a numeric
- * value such as 12345 to the string "$12,345".  It may also parse
- * the string back into a numeric value.  A date and time formatter
- * like SimpleDateFormat may represent a specific date, encoded
- * numerically, as a string such as "Wednesday, February 26, 1997 AD".
- * <P>
- * Many of the concrete subclasses of Format employ the notion of
- * a pattern.  A pattern is a string representation of the rules which
- * govern the interconversion between values and strings.  For example,
- * a DecimalFormat object may be associated with the pattern
- * "$#,##0.00;($#,##0.00)", which is a common US English format for
- * currency values, yielding strings such as "$1,234.45" for 1234.45,
- * and "($987.65)" for 987.6543.  The specific syntax of a pattern
- * is defined by each subclass.
- * <P>
- * Even though many subclasses use patterns, the notion of a pattern
- * is not inherent to Format classes in general, and is not part of
- * the explicit base class protocol.
- * <P>
- * Two complex formatting classes bear mentioning.  These are
- * MessageFormat and ChoiceFormat.  ChoiceFormat is a subclass of
- * NumberFormat which allows the user to format different number ranges
- * as strings.  For instance, 0 may be represented as "no files", 1 as
- * "one file", and any number greater than 1 as "many files".
- * MessageFormat is a formatter which utilizes other Format objects to
- * format a string containing with multiple values.  For instance,
- * A MessageFormat object might produce the string "There are no files
- * on the disk MyDisk on February 27, 1997." given the arguments 0,
- * "MyDisk", and the date value of 2/27/97.  See the ChoiceFormat
- * and MessageFormat headers for further information.
- * <P>
- * If formatting is unsuccessful, a failing UErrorCode is returned when
- * the Format cannot format the type of object, otherwise if there is
- * something illformed about the the Unicode replacement character
- * 0xFFFD is returned.
- * <P>
- * If there is no match when parsing, a parse failure UErrorCode is
- * retured for methods which take no ParsePosition.  For the method
- * that takes a ParsePosition, the index parameter is left unchanged.
- * <P>
- * <em>User subclasses are not supported.</em> While clients may write
- * subclasses, such code will not necessarily work and will not be
- * guaranteed to work stably from release to release.

-U_NAMESPACE_BEGIN
-
-/** 
- * Concrete class which provides the standard calendar used by most of the world.
- * <P>
- * The standard (Gregorian) calendar has 2 eras, BC and AD.
- * <P>
- * This implementation handles a single discontinuity, which corresponds by default to
- * the date the Gregorian calendar was originally instituted (October 15, 1582). Not all
- * countries adopted the Gregorian calendar then, so this cutover date may be changed by
- * the caller.
- * <P>
- * Prior to the institution of the Gregorian Calendar, New Year's Day was March 25. To
- * avoid confusion, this Calendar always uses January 1. A manual adjustment may be made
- * if desired for dates that are prior to the Gregorian changeover and which fall
- * between January 1 and March 24.
- *
- * <p>Values calculated for the <code>WEEK_OF_YEAR</code> field range from 1 to
- * 53.  Week 1 for a year is the first week that contains at least
- * <code>getMinimalDaysInFirstWeek()</code> days from that year.  It thus
- * depends on the values of <code>getMinimalDaysInFirstWeek()</code>,
- * <code>getFirstDayOfWeek()</code>, and the day of the week of January 1.
- * Weeks between week 1 of one year and week 1 of the following year are
- * numbered sequentially from 2 to 52 or 53 (as needed).
- *
- * <p>For example, January 1, 1998 was a Thursday.  If
- * <code>getFirstDayOfWeek()</code> is <code>MONDAY</code> and
- * <code>getMinimalDaysInFirstWeek()</code> is 4 (these are the values
- * reflecting ISO 8601 and many national standards), then week 1 of 1998 starts
- * on December 29, 1997, and ends on January 4, 1998.  If, however,
- * <code>getFirstDayOfWeek()</code> is <code>SUNDAY</code>, then week 1 of 1998
- * starts on January 4, 1998, and ends on January 10, 1998; the first three days
- * of 1998 then are part of week 53 of 1997.
- *
- * <p>Example for using GregorianCalendar:
- * <pre>
- * \code
- *     // get the supported ids for GMT-08:00 (Pacific Standard Time)
- *     UErrorCode success = U_ZERO_ERROR;
- *     const StringEnumeration *ids = TimeZone::createEnumeration(-8 * 60 * 60 * 1000);
- *     // if no ids were returned, something is wrong. get out.
- *     if (ids == 0 || ids->count(success) == 0) {
- *         return;
- *     }
- *
- *     // begin output
- *     cout << "Current Time" << endl;
- *
- *     // create a Pacific Standard Time time zone
- *     SimpleTimeZone* pdt = new SimpleTimeZone(-8 * 60 * 60 * 1000, ids->unext(NULL, success)));
- *
- *     // set up rules for daylight savings time
- *     pdt->setStartRule(UCAL_MARCH, 1, UCAL_SUNDAY, 2 * 60 * 60 * 1000);
- *     pdt->setEndRule(UCAL_NOVEMBER, 2, UCAL_SUNDAY, 2 * 60 * 60 * 1000);
- *
- *     // create a GregorianCalendar with the Pacific Daylight time zone
- *     // and the current date and time
- *     Calendar* calendar = new GregorianCalendar( pdt, success );

- * \file
- * \brief C API: ICU Plugin API 
- *
- * <h2>C API: ICU Plugin API</h2>
- *
- * <p>C API allowing run-time loadable modules that extend or modify ICU functionality.</p>
- *
- * <h3>Loading and Configuration</h3>
- *
- * <p>At ICU startup time, the environment variable "ICU_PLUGINS" will be 
- * queried for a directory name.  If it is not set, the preprocessor symbol 
- * "DEFAULT_ICU_PLUGINS" will be checked for a default value.</p>
- *
- * <p>Within the above-named directory, the file  "icuplugins##.txt" will be 
- * opened, if present, where ## is the major+minor number of the currently 
- * running ICU (such as, 44 for ICU 4.4, thus icuplugins44.txt)</p>
- *
- * <p>The configuration file has this format:</p>
- *
- * <ul>
- * <li>Hash (#) begins a comment line</li>
- * 
- * <li>Non-comment lines have two or three components:
- * LIBRARYNAME     ENTRYPOINT     [ CONFIGURATION .. ]</li>
- *
- * <li>Tabs or spaces separate the three items.</li>
- *
- * <li>LIBRARYNAME is the name of a shared library, either a short name if 
- * it is on the loader path,  or a full pathname.</li>
- *
- * <li>ENTRYPOINT is the short (undecorated) symbol name of the plugin's 
- * entrypoint, as above.</li>
- *
- * <li>CONFIGURATION is the entire rest of the line . It's passed as-is to 
- * the plugin.</li>
- * </ul>
- *
- * <p>An example configuration file is, in its entirety:</p>
- *
- * \code
- * # this is icuplugins44.txt
- * testplug.dll    myPlugin        hello=world
- * \endcode
- * <p>Plugins are categorized as "high" or "low" level.  Low level are those 
- * which must be run BEFORE high level plugins, and before any operations 
- * which cause ICU to be 'initialized'.  If a plugin is low level but 
- * causes ICU to allocate memory or become initialized, that plugin is said 
- * to cause a 'level change'. </p>
- *
- * <p>At load time, ICU first queries all plugins to determine their level, 
- * then loads all 'low' plugins first, and then loads all 'high' plugins.  
- * Plugins are otherwise loaded in the order listed in the configuration file.</p>
- * 
- * <h3>Implementing a Plugin</h3>
- * \code
- * U_CAPI UPlugTokenReturn U_EXPORT2 
- * myPlugin (UPlugData *plug, UPlugReason reason, UErrorCode *status) {
- *   if(reason==UPLUG_REASON_QUERY) {
- *      uplug_setPlugName(plug, "Simple Plugin");
- *      uplug_setPlugLevel(plug, UPLUG_LEVEL_HIGH);
- *    } else if(reason==UPLUG_REASON_LOAD) {
- *       ... Set up some ICU things here.... 
- *    } else if(reason==UPLUG_REASON_UNLOAD) {
- *       ... unload, clean up ...
- *    }
- *   return UPLUG_TOKEN;
- *  }
- * \endcode
- *
- * <p>The UPlugData*  is an opaque pointer to the plugin-specific data, and is 
- * used in all other API calls.</p>
- *
- * <p>The API contract is:</p>
- * <ol><li>The plugin MUST always return UPLUG_TOKEN as a return value- to 
- * indicate that it is a valid plugin.</li>
- *
- * <li>When the 'reason' parameter is set to UPLUG_REASON_QUERY,  the 
- * plugin MUST call uplug_setPlugLevel() to indicate whether it is a high 
- * level or low level plugin.</li>
- *
- * <li>When the 'reason' parameter is UPLUG_REASON_QUERY, the plugin 
- * SHOULD call uplug_setPlugName to indicate a human readable plugin name.</li></ol>

- * <code>LocaleBuilder</code> is used to build instances of <code>Locale</code>
- * from values configured by the setters.  Unlike the <code>Locale</code>
- * constructors, the <code>LocaleBuilder</code> checks if a value configured by a
- * setter satisfies the syntax requirements defined by the <code>Locale</code>
- * class.  A <code>Locale</code> object created by a <code>LocaleBuilder</code> is
- * well-formed and can be transformed to a well-formed IETF BCP 47 language tag
- * without losing information.
- *
- * <p>The following example shows how to create a <code>Locale</code> object
- * with the <code>LocaleBuilder</code>.
- * <blockquote>
- * <pre>
- *     UErrorCode status = U_ZERO_ERROR;
- *     Locale aLocale = LocaleBuilder()
- *                          .setLanguage("sr")
- *                          .setScript("Latn")
- *                          .setRegion("RS")
- *                          .build(status);
- *     if (U_SUCCESS(status)) {
- *       // ...
- *     }
- * </pre>
- * </blockquote>
- *
- * <p>LocaleBuilders can be reused; <code>clear()</code> resets all
- * fields to their default values.
- *
- * <p>LocaleBuilder tracks errors in an internal UErrorCode. For all setters,
- * except setLanguageTag and setLocale, LocaleBuilder will return immediately
- * if the internal UErrorCode is in error state.
- * To reset internal state and error code, call clear method.
- * The setLanguageTag and setLocale method will first clear the internal
- * UErrorCode, then track the error of the validation of the input parameter
- * into the internal UErrorCode.

-/**
- * Immutable class that picks the best match between a user's desired locales and
- * an application's supported locales.
- * Movable but not copyable.
- *
- * <p>Example:
- * <pre>
- * UErrorCode errorCode = U_ZERO_ERROR;
- * LocaleMatcher matcher = LocaleMatcher::Builder().setSupportedLocales("fr, en-GB, en").build(errorCode);
- * Locale *bestSupported = matcher.getBestLocale(Locale.US, errorCode);  // "en"
- * </pre>
- *
- * <p>A matcher takes into account when languages are close to one another,
- * such as Danish and Norwegian,
- * and when regional variants are close, like en-GB and en-AU as opposed to en-US.
- *
- * <p>If there are multiple supported locales with the same (language, script, region)
- * likely subtags, then the current implementation returns the first of those locales.
- * It ignores variant subtags (except for pseudolocale variants) and extensions.
- * This may change in future versions.
- *
- * <p>For example, the current implementation does not distinguish between
- * de, de-DE, de-Latn, de-1901, de-u-co-phonebk.
- *
- * <p>If you prefer one equivalent locale over another, then provide only the preferred one,
- * or place it earlier in the list of supported locales.
- *
- * <p>Otherwise, the order of supported locales may have no effect on the best-match results.
- * The current implementation compares each desired locale with supported locales
- * in the following order:
- * 1. Default locale, if supported;
- * 2. CLDR "paradigm locales" like en-GB and es-419;
- * 3. other supported locales.
- * This may change in future versions.
- *
- * <p>Often a product will just need one matcher instance, built with the languages
- * that it supports. However, it may want multiple instances with different
- * default languages based on additional information, such as the domain.
- *
- * <p>This class is not intended for public subclassing.

- * \brief C++ API: "Smart pointers" for use with and in ICU4C C++ code.
- *
- * These classes are inspired by
- * - std::auto_ptr
- * - boost::scoped_ptr & boost::scoped_array
- * - Taligent Safe Pointers (TOnlyPointerTo)
- *
- * but none of those provide for all of the goals for ICU smart pointers:
- * - Smart pointer owns the object and releases it when it goes out of scope.
- * - No transfer of ownership via copy/assignment to reduce misuse. Simpler & more robust.
- * - ICU-compatible: No exceptions.
- * - Need to be able to orphan/release the pointer and its ownership.
- * - Need variants for normal C++ object pointers, C++ arrays, and ICU C service objects.
- *
- * For details see http://site.icu-project.org/design/cpp/scoped_ptr

-/**
- * A <code>Locale</code> object represents a specific geographical, political,
- * or cultural region. An operation that requires a <code>Locale</code> to perform
- * its task is called <em>locale-sensitive</em> and uses the <code>Locale</code>
- * to tailor information for the user. For example, displaying a number
- * is a locale-sensitive operation--the number should be formatted
- * according to the customs/conventions of the user's native country,
- * region, or culture.
- *
- * The Locale class is not suitable for subclassing.
- *
- * <P>
- * You can create a <code>Locale</code> object using the constructor in
- * this class:
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- *       Locale( const   char*  language,
- *               const   char*  country,
- *               const   char*  variant);
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * The first argument to the constructors is a valid <STRONG>ISO
- * Language Code.</STRONG> These codes are the lower-case two-letter
- * codes as defined by ISO-639.
- * You can find a full list of these codes at:
- * <BR><a href ="http://www.loc.gov/standards/iso639-2/">
- * http://www.loc.gov/standards/iso639-2/</a>
- *
- * <P>
- * The second argument to the constructors is a valid <STRONG>ISO Country
- * Code.</STRONG> These codes are the upper-case two-letter codes
- * as defined by ISO-3166.
- * You can find a full list of these codes at a number of sites, such as:
- * <BR><a href="http://www.iso.org/iso/en/prods-services/iso3166ma/index.html">
- * http://www.iso.org/iso/en/prods-services/iso3166ma/index.html</a>
- *
- * <P>
- * The third constructor requires a third argument--the <STRONG>Variant.</STRONG>
- * The Variant codes are vendor and browser-specific.
- * For example, use REVISED for a language's revised script orthography, and POSIX for POSIX.
- * Where there are two variants, separate them with an underscore, and
- * put the most important one first. For
- * example, a Traditional Spanish collation might be referenced, with
- * "ES", "ES", "Traditional_POSIX".
- *
- * <P>
- * Because a <code>Locale</code> object is just an identifier for a region,
- * no validity check is performed when you construct a <code>Locale</code>.
- * If you want to see whether particular resources are available for the
- * <code>Locale</code> you construct, you must query those resources. For
- * example, ask the <code>NumberFormat</code> for the locales it supports
- * using its <code>getAvailableLocales</code> method.
- * <BR><STRONG>Note:</STRONG> When you ask for a resource for a particular
- * locale, you get back the best available match, not necessarily
- * precisely what you asked for. For more information, look at
- * <code>ResourceBundle</code>.
- *
- * <P>
- * The <code>Locale</code> class provides a number of convenient constants
- * that you can use to create <code>Locale</code> objects for commonly used
- * locales. For example, the following refers to a <code>Locale</code> object
- * for the United States:
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- *       Locale::getUS()
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * <P>
- * Once you've created a <code>Locale</code> you can query it for information about
- * itself. Use <code>getCountry</code> to get the ISO Country Code and
- * <code>getLanguage</code> to get the ISO Language Code. You can
- * use <code>getDisplayCountry</code> to get the
- * name of the country suitable for displaying to the user. Similarly,
- * you can use <code>getDisplayLanguage</code> to get the name of
- * the language suitable for displaying to the user. Interestingly,
- * the <code>getDisplayXXX</code> methods are themselves locale-sensitive
- * and have two versions: one that uses the default locale and one
- * that takes a locale as an argument and displays the name or country in
- * a language appropriate to that locale.
- *
- * <P>
- * ICU provides a number of classes that perform locale-sensitive
- * operations. For example, the <code>NumberFormat</code> class formats
- * numbers, currency, or percentages in a locale-sensitive manner. Classes
- * such as <code>NumberFormat</code> have a number of convenience methods
- * for creating a default object of that type. For example, the
- * <code>NumberFormat</code> class provides these three convenience methods
- * for creating a default <code>NumberFormat</code> object:
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>

-/**
- * <p>MessageFormat prepares strings for display to users,
- * with optional arguments (variables/placeholders).
- * The arguments can occur in any order, which is necessary for translation
- * into languages with different grammars.
- *
- * <p>A MessageFormat is constructed from a <em>pattern</em> string
- * with arguments in {curly braces} which will be replaced by formatted values.
- *
- * <p><code>MessageFormat</code> differs from the other <code>Format</code>
- * classes in that you create a <code>MessageFormat</code> object with one
- * of its constructors (not with a <code>createInstance</code> style factory
- * method). Factory methods aren't necessary because <code>MessageFormat</code>
- * itself doesn't implement locale-specific behavior. Any locale-specific
- * behavior is defined by the pattern that you provide and the
- * subformats used for inserted arguments.
- *
- * <p>Arguments can be named (using identifiers) or numbered (using small ASCII-digit integers).
- * Some of the API methods work only with argument numbers and throw an exception
- * if the pattern has named arguments (see {@link #usesNamedArguments()}).
- *
- * <p>An argument might not specify any format type. In this case,
- * a numeric value is formatted with a default (for the locale) NumberFormat,
- * and a date/time value is formatted with a default (for the locale) DateFormat.
- *
- * <p>An argument might specify a "simple" type for which the specified
- * Format object is created, cached and used.
- *
- * <p>An argument might have a "complex" type with nested MessageFormat sub-patterns.
- * During formatting, one of these sub-messages is selected according to the argument value
- * and recursively formatted.
- *
- * <p>After construction, a custom Format object can be set for
- * a top-level argument, overriding the default formatting and parsing behavior
- * for that argument.
- * However, custom formatting can be achieved more simply by writing
- * a typeless argument in the pattern string
- * and supplying it with a preformatted string value.
- *
- * <p>When formatting, MessageFormat takes a collection of argument values
- * and writes an output string.
- * The argument values may be passed as an array
- * (when the pattern contains only numbered arguments)
- * or as an array of names and and an array of arguments (which works for both named
- * and numbered arguments).
- *
- * <p>Each argument is matched with one of the input values by array index or argument name
- * and formatted according to its pattern specification
- * (or using a custom Format object if one was set).
- * A numbered pattern argument is matched with an argument name that contains that number
- * as an ASCII-decimal-digit string (without leading zero).
- *
- * <h4><a name="patterns">Patterns and Their Interpretation</a></h4>
- *
- * <code>MessageFormat</code> uses patterns of the following form:
- * <pre>
- * message = messageText (argument messageText)*
- * argument = noneArg | simpleArg | complexArg
- * complexArg = choiceArg | pluralArg | selectArg | selectordinalArg
- *
- * noneArg = '{' argNameOrNumber '}'
- * simpleArg = '{' argNameOrNumber ',' argType [',' argStyle] '}'
- * choiceArg = '{' argNameOrNumber ',' "choice" ',' choiceStyle '}'
- * pluralArg = '{' argNameOrNumber ',' "plural" ',' pluralStyle '}'
- * selectArg = '{' argNameOrNumber ',' "select" ',' selectStyle '}'
- * selectordinalArg = '{' argNameOrNumber ',' "selectordinal" ',' pluralStyle '}'
- *
- * choiceStyle: see {@link ChoiceFormat}
- * pluralStyle: see {@link PluralFormat}
- * selectStyle: see {@link SelectFormat}
- *
- * argNameOrNumber = argName | argNumber
- * argName = [^[[:Pattern_Syntax:][:Pattern_White_Space:]]]+
- * argNumber = '0' | ('1'..'9' ('0'..'9')*)
- *
- * argType = "number" | "date" | "time" | "spellout" | "ordinal" | "duration"
- * argStyle = "short" | "medium" | "long" | "full" | "integer" | "currency" | "percent" | argStyleText | "::" argSkeletonText
- * </pre>
- *
- * <ul>
- *   <li>messageText can contain quoted literal strings including syntax characters.
- *       A quoted literal string begins with an ASCII apostrophe and a syntax character
- *       (usually a {curly brace}) and continues until the next single apostrophe.
- *       A double ASCII apostrohpe inside or outside of a quoted string represents
- *       one literal apostrophe.
- *   <li>Quotable syntax characters are the {curly braces} in all messageText parts,
- *       plus the '#' sign in a messageText immediately inside a pluralStyle,
- *       and the '|' symbol in a messageText immediately inside a choiceStyle.
- *   <li>See also {@link #UMessagePatternApostropheMode}
- *   <li>In argStyleText, every single ASCII apostrophe begins and ends quoted literal text,
- *       and unquoted {curly braces} must occur in matched pairs.
- * </ul>
- *
- * <p>Recommendation: Use the real apostrophe (single quote) character
- * \htmlonly&#x2019;\endhtmlonly (U+2019) for
- * human-readable text, and use the ASCII apostrophe ' (U+0027)
- * only in program syntax, like quoting in MessageFormat.
- * See the annotations for U+0027 Apostrophe in The Unicode Standard.
- *
- * <p>The <code>choice</code> argument type is deprecated.
- * Use <code>plural</code> arguments for proper plural selection,
- * and <code>select</code> arguments for simple selection among a fixed set of choices.
- *
- * <p>The <code>argType</code> and <code>argStyle</code> values are used to create
- * a <code>Format</code> instance for the format element. The following
- * table shows how the values map to Format instances. Combinations not
- * shown in the table are illegal. Any <code>argStyleText</code> must
- * be a valid pattern string for the Format subclass used.

- * <h4>Argument formatting</h4>
- *
- * <p>Arguments are formatted according to their type, using the default
- * ICU formatters for those types, unless otherwise specified.</p>
- *
- * <p>There are also several ways to control the formatting.</p>
- *
- * <p>We recommend you use default styles, predefined style values, skeletons,
- * or preformatted values, but not pattern strings or custom format objects.</p>
- *
- * <p>For more details, see the
- * <a href="http://userguide.icu-project.org/formatparse/messages">ICU User Guide</a>.</p>
- *
- * <h4>Usage Information</h4>
- *
- * <p>Here are some examples of usage:
- * Example 1:
- *
- * <pre>
- * \code
- *     UErrorCode success = U_ZERO_ERROR;
- *     GregorianCalendar cal(success);
- *     Formattable arguments[] = {
- *         7L,
- *         Formattable( (Date) cal.getTime(success), Formattable::kIsDate),
- *         "a disturbance in the Force"
- *     };
- *
- *     UnicodeString result;
- *     MessageFormat::format(
- *          "At {1,time,::jmm} on {1,date,::dMMMM}, there was {2} on planet {0,number}.",
- *          arguments, 3, result, success );
- *
- *     cout << "result: " << result << endl;
- *     //<output>: At 4:34 PM on March 23, there was a disturbance
- *     //             in the Force on planet 7.
- * \endcode
- * </pre>
- *
- * Typically, the message format will come from resources, and the
- * arguments will be dynamically set at runtime.
- *
- * <p>Example 2:
- *
- * <pre>
- *  \code
- *     success = U_ZERO_ERROR;
- *     Formattable testArgs[] = {3L, "MyDisk"};
- *
- *     MessageFormat form(
- *         "The disk \"{1}\" contains {0} file(s).", success );
- *
- *     UnicodeString string;
- *     FieldPosition fpos = 0;
- *     cout << "format: " << form.format(testArgs, 2, string, fpos, success ) << endl;
- *
- *     // output, with different testArgs:
- *     // output: The disk "MyDisk" contains 0 file(s).
- *     // output: The disk "MyDisk" contains 1 file(s).
- *     // output: The disk "MyDisk" contains 1,273 file(s).
- *  \endcode
- *  </pre>
- *
- *
- * <p>For messages that include plural forms, you can use a plural argument:
- * <pre>
- * \code
- *  success = U_ZERO_ERROR;
- *  MessageFormat msgFmt(
- *       "{num_files, plural, "
- *       "=0{There are no files on disk \"{disk_name}\".}"
- *       "=1{There is one file on disk \"{disk_name}\".}"
- *       "other{There are # files on disk \"{disk_name}\".}}",
- *      Locale("en"),
- *      success);
- *  FieldPosition fpos = 0;
- *  Formattable testArgs[] = {0L, "MyDisk"};
- *  UnicodeString testArgsNames[] = {"num_files", "disk_name"};
- *  UnicodeString result;
- *  cout << msgFmt.format(testArgs, testArgsNames, 2, result, fpos, 0, success);
- *  testArgs[0] = 3L;
- *  cout << msgFmt.format(testArgs, testArgsNames, 2, result, fpos, 0, success);
- * \endcode
- * <em>output</em>:
- * There are no files on disk "MyDisk".
- * There are 3 files on "MyDisk".
- * </pre>
- * See {@link PluralFormat} and {@link PluralRules} for details.
- *
- * <h4><a name="synchronization">Synchronization</a></h4>
- *
- * <p>MessageFormats are not synchronized.
- * It is recommended to create separate format instances for each thread.
- * If multiple threads access a format concurrently, it must be synchronized
- * externally.

-/**
- * Unicode normalization functionality for standard Unicode normalization or
- * for using custom mapping tables.
- * All instances of this class are unmodifiable/immutable.
- * Instances returned by getInstance() are singletons that must not be deleted by the caller.
- * The Normalizer2 class is not intended for public subclassing.
- *
- * The primary functions are to produce a normalized string and to detect whether
- * a string is already normalized.
- * The most commonly used normalization forms are those defined in
- * http://www.unicode.org/unicode/reports/tr15/
- * However, this API supports additional normalization forms for specialized purposes.
- * For example, NFKC_Casefold is provided via getInstance("nfkc_cf", COMPOSE)
- * and can be used in implementations of UTS #46.
- *
- * Not only are the standard compose and decompose modes supplied,
- * but additional modes are provided as documented in the Mode enum.
- *
- * Some of the functions in this class identify normalization boundaries.
- * At a normalization boundary, the portions of the string
- * before it and starting from it do not interact and can be handled independently.
- *
- * The spanQuickCheckYes() stops at a normalization boundary.
- * When the goal is a normalized string, then the text before the boundary
- * can be copied, and the remainder can be processed with normalizeSecondAndAppend().
- *
- * The hasBoundaryBefore(), hasBoundaryAfter() and isInert() functions test whether
- * a character is guaranteed to be at a normalization boundary,
- * regardless of context.
- * This is used for moving from one normalization boundary to the next
- * or preceding boundary, and for performing iterative normalization.
- *
- * Iterative normalization is useful when only a small portion of a
- * longer string needs to be processed.
- * For example, in ICU, iterative normalization is used by the NormalizationTransliterator
- * (to avoid replacing already-normalized text) and ucol_nextSortKeyPart()
- * (to process only the substring for which sort key bytes are computed).
- *
- * The set of normalization boundaries returned by these functions may not be
- * complete: There may be more boundaries that could be returned.
- * Different functions may return different boundaries.

-/**
- * Old Unicode normalization API.
- *
- * This API has been replaced by the Normalizer2 class and is only available
- * for backward compatibility. This class simply delegates to the Normalizer2 class.
- * There is one exception: The new API does not provide a replacement for Normalizer::compare().
- *
- * The Normalizer class supports the standard normalization forms described in
- * <a href="http://www.unicode.org/unicode/reports/tr15/" target="unicode">
- * Unicode Standard Annex #15: Unicode Normalization Forms</a>.
- *
- * The Normalizer class consists of two parts:
- * - static functions that normalize strings or test if strings are normalized
- * - a Normalizer object is an iterator that takes any kind of text and
- *   provides iteration over its normalized form
- *
- * The Normalizer class is not suitable for subclassing.
- *
- * For basic information about normalization forms and details about the C API
- * please see the documentation in unorm.h.
- *
- * The iterator API with the Normalizer constructors and the non-static functions
- * use a CharacterIterator as input. It is possible to pass a string which
- * is then internally wrapped in a CharacterIterator.
- * The input text is not normalized all at once, but incrementally where needed
- * (providing efficient random access).
- * This allows to pass in a large text but spend only a small amount of time
- * normalizing a small part of that text.
- * However, if the entire text is normalized, then the iterator will be
- * slower than normalizing the entire text at once and iterating over the result.
- * A possible use of the Normalizer iterator is also to report an index into the
- * original text that is close to where the normalized characters come from.
- *
- * <em>Important:</em> The iterator API was cleaned up significantly for ICU 2.0.
- * The earlier implementation reported the getIndex() inconsistently,
- * and previous() could not be used after setIndex(), next(), first(), and current().
- *
- * Normalizer allows to start normalizing from anywhere in the input text by
- * calling setIndexOnly(), first(), or last().
- * Without calling any of these, the iterator will start at the beginning of the text.
- *
- * At any time, next() returns the next normalized code point (UChar32),
- * with post-increment semantics (like CharacterIterator::next32PostInc()).
- * previous() returns the previous normalized code point (UChar32),
- * with pre-decrement semantics (like CharacterIterator::previous32()).
- *
- * current() returns the current code point
- * (respectively the one at the newly set index) without moving
- * the getIndex(). Note that if the text at the current position
- * needs to be normalized, then these functions will do that.
- * (This is why current() is not const.)
- * It is more efficient to call setIndexOnly() instead, which does not
- * normalize.
- *
- * getIndex() always refers to the position in the input text where the normalized
- * code points are returned from. It does not always change with each returned
- * code point.
- * The code point that is returned from any of the functions
- * corresponds to text at or after getIndex(), according to the
- * function's iteration semantics (post-increment or pre-decrement).
- *
- * next() returns a code point from at or after the getIndex()
- * from before the next() call. After the next() call, the getIndex()
- * might have moved to where the next code point will be returned from
- * (from a next() or current() call).
- * This is semantically equivalent to array access with array[index++]
- * (post-increment semantics).
- *
- * previous() returns a code point from at or after the getIndex()
- * from after the previous() call.
- * This is semantically equivalent to array access with array[--index]
- * (pre-decrement semantics).
- *
- * Internally, the Normalizer iterator normalizes a small piece of text
- * starting at the getIndex() and ending at a following "safe" index.
- * The normalized results is stored in an internal string buffer, and
- * the code points are iterated from there.
- * With multiple iteration calls, this is repeated until the next piece
- * of text needs to be normalized, and the getIndex() needs to be moved.
- *
- * The following "safe" index, the internal buffer, and the secondary
- * iteration index into that buffer are not exposed on the API.
- * This also means that it is currently not practical to return to
- * a particular, arbitrary position in the text because one would need to
- * know, and be able to set, in addition to the getIndex(), at least also the
- * current index into the internal buffer.
- * It is currently only possible to observe when getIndex() changes
- * (with careful consideration of the iteration semantics),
- * at which time the internal index will be 0.
- * For example, if getIndex() is different after next() than before it,
- * then the internal index is 0 and one can return to this getIndex()
- * later with setIndexOnly().
- *
- * Note: While the setIndex() and getIndex() refer to indices in the
- * underlying Unicode input text, the next() and previous() methods
- * iterate through characters in the normalized output.
- * This means that there is not necessarily a one-to-one correspondence
- * between characters returned by next() and previous() and the indices
- * passed to and returned from setIndex() and getIndex().
- * It is for this reason that Normalizer does not implement the CharacterIterator interface.

-/**
- * \file
- * \brief C++ API: Library for localized number formatting introduced in ICU 60.
- *
- * This library was introduced in ICU 60 to simplify the process of formatting localized number strings.
- * Basic usage examples:
- *
- * <pre>
- * // Most basic usage:
- * NumberFormatter::withLocale(...).format(123).toString();  // 1,234 in en-US
- *
- * // Custom notation, unit, and rounding precision:
- * NumberFormatter::with()
- *     .notation(Notation::compactShort())
- *     .unit(CurrencyUnit("EUR", status))
- *     .precision(Precision::maxDigits(2))
- *     .locale(...)
- *     .format(1234)
- *     .toString();  // €1.2K in en-US
- *
- * // Create a formatter in a singleton by value for use later:
- * static const LocalizedNumberFormatter formatter = NumberFormatter::withLocale(...)
- *     .unit(NoUnit::percent())
- *     .precision(Precision::fixedFraction(3));
- * formatter.format(5.9831).toString();  // 5.983% in en-US
- *
- * // Create a "template" in a singleton unique_ptr but without setting a locale until the call site:
- * std::unique_ptr<UnlocalizedNumberFormatter> template = NumberFormatter::with()
- *     .sign(UNumberSignDisplay::UNUM_SIGN_ALWAYS)
- *     .unit(MeasureUnit::getMeter())
- *     .unitWidth(UNumberUnitWidth::UNUM_UNIT_WIDTH_FULL_NAME)
- *     .clone();
- * template->locale(...).format(1234).toString();  // +1,234 meters in en-US
- * </pre>
- *
- * <p>
- * This API offers more features than DecimalFormat and is geared toward new users of ICU.
- *
- * <p>
- * NumberFormatter instances (i.e., LocalizedNumberFormatter and UnlocalizedNumberFormatter)
- * are immutable and thread safe. This means that invoking a configuration method has no
- * effect on the receiving instance; you must store and use the new number formatter instance it returns instead.
- *
- * <pre>
- * UnlocalizedNumberFormatter formatter = UnlocalizedNumberFormatter::with().notation(Notation::scientific());
- * formatter.precision(Precision.maxFraction(2)); // does nothing!
- * formatter.locale(Locale.getEnglish()).format(9.8765).toString(); // prints "9.8765E0", not "9.88E0"
- * </pre>
- *
- * <p>
- * This API is based on the <em>fluent</em> design pattern popularized by libraries such as Google's Guava. For
- * extensive details on the design of this API, read <a href="https://goo.gl/szi5VB">the design doc</a>.

-/**
- * \file
- * \brief C++ API: Library for localized formatting of number, currency, and unit ranges.
- *
- * The main entrypoint to the formatting of ranges of numbers, including currencies and other units of measurement.
- * <p>
- * Usage example:
- * <p>
- * <pre>
- * NumberRangeFormatter::with()
- *     .identityFallback(UNUM_IDENTITY_FALLBACK_APPROXIMATELY_OR_SINGLE_VALUE)
- *     .numberFormatterFirst(NumberFormatter::with().adoptUnit(MeasureUnit::createMeter()))
- *     .numberFormatterSecond(NumberFormatter::with().adoptUnit(MeasureUnit::createKilometer()))
- *     .locale("en-GB")
- *     .formatRange(750, 1.2, status)
- *     .toString(status);
- * // => "750 m - 1.2 km"
- * </pre>
- * <p>
- * Like NumberFormatter, NumberRangeFormatter instances (i.e., LocalizedNumberRangeFormatter
- * and UnlocalizedNumberRangeFormatter) are immutable and thread-safe. This API is based on the
- * <em>fluent</em> design pattern popularized by libraries such as Google's Guava.

-/**
- * <p><strong>IMPORTANT:</strong> New users are strongly encouraged to see if
- * numberformatter.h fits their use case.  Although not deprecated, this header
- * is provided for backwards compatibility only.
- *
- * Abstract base class for all number formats.  Provides interface for
- * formatting and parsing a number.  Also provides methods for
- * determining which locales have number formats, and what their names
- * are.
- *
- * \headerfile unicode/numfmt.h "unicode/numfmt.h"
- * <P>
- * NumberFormat helps you to format and parse numbers for any locale.
- * Your code can be completely independent of the locale conventions
- * for decimal points, thousands-separators, or even the particular
- * decimal digits used, or whether the number format is even decimal.
- * <P>
- * To format a number for the current Locale, use one of the static
- * factory methods:
- * \code
- *    #include <iostream>
- *    #include "unicode/numfmt.h"
- *    #include "unicode/unistr.h"
- *    #include "unicode/ustream.h"
- *    using namespace std;
- *    
- *    int main() {
- *        double myNumber = 7.0;
- *        UnicodeString myString;
- *        UErrorCode success = U_ZERO_ERROR;
- *        NumberFormat* nf = NumberFormat::createInstance(success);
- *        nf->format(myNumber, myString);
- *        cout << " Example 1: " << myString << endl;
- *    }
- * \endcode
- * Note that there are additional factory methods within subclasses of
- * NumberFormat.
- * <P>
- * If you are formatting multiple numbers, it is more efficient to get
- * the format and use it multiple times so that the system doesn't
- * have to fetch the information about the local language and country
- * conventions multiple times.
- * \code
- *     UnicodeString myString;
- *     UErrorCode success = U_ZERO_ERROR;
- *     NumberFormat *nf = NumberFormat::createInstance( success );
- *     for (int32_t number: {123, 3333, -1234567}) {
- *         nf->format(number, myString);
- *         myString += "; ";
- *     }
- *     cout << " Example 2: " << myString << endl;
- * \endcode
- * To format a number for a different Locale, specify it in the
- * call to \c createInstance().
- * \code
- *     nf = NumberFormat::createInstance(Locale::getFrench(), success);
- * \endcode
- * You can use a \c NumberFormat to parse also.
- * \code
- *    UErrorCode success;
- *    Formattable result(-999);  // initialized with error code
- *    nf->parse(myString, result, success);
- * \endcode
- * Use \c createInstance() to get the normal number format for a \c Locale.
- * There are other static factory methods available.  Use \c createCurrencyInstance()
- * to get the currency number format for that country.  Use \c createPercentInstance()
- * to get a format for displaying percentages. With this format, a
- * fraction from 0.53 is displayed as 53%.
- * <P>
- * The type of number formatting can be specified by passing a 'style' parameter to \c createInstance().
- * For example, use\n
- * \c createInstance(locale, UNUM_DECIMAL, errorCode) to get the normal number format,\n
- * \c createInstance(locale, UNUM_PERCENT, errorCode) to get a format for displaying percentage,\n
- * \c createInstance(locale, UNUM_SCIENTIFIC, errorCode) to get a format for displaying scientific number,\n
- * \c createInstance(locale, UNUM_CURRENCY, errorCode) to get the currency number format,
- * in which the currency is represented by its symbol, for example, "$3.00".\n
- * \c createInstance(locale, UNUM_CURRENCY_ISO, errorCode)  to get the currency number format,
- * in which the currency is represented by its ISO code, for example "USD3.00".\n
- * \c createInstance(locale, UNUM_CURRENCY_PLURAL, errorCode) to get the currency number format,
- * in which the currency is represented by its full name in plural format,
- * for example, "3.00 US dollars" or "1.00 US dollar".
- * <P>
- * You can also control the display of numbers with such methods as
- * \c getMinimumFractionDigits().  If you want even more control over the
- * format or parsing, or want to give your users more control, you can
- * try dynamic_casting the \c NumberFormat you get from the factory methods to a
- * \c DecimalFormat. This will work for the vast majority of
- * countries; just remember to test for NULL in case you
- * encounter an unusual one.
- * <P>
- * You can also use forms of the parse and format methods with
- * \c ParsePosition and \c FieldPosition to allow you to:
- * <ul type=round>
- *   <li>(a) progressively parse through pieces of a string.
- *   <li>(b) align the decimal point and other areas.
- * </ul>
- * For example, you can align numbers in two ways.
- * <P>
- * If you are using a monospaced font with spacing for alignment, you
- * can pass the \c FieldPosition in your format call, with field =
- * \c UNUM_INTEGER_FIELD. On output, \c getEndIndex will be set to the offset
- * between the last character of the integer and the decimal. Add
- * (desiredSpaceCount - getEndIndex) spaces at the front of the
- * string.
- * <P>
- * If you are using proportional fonts, instead of padding with
- * spaces, measure the width of the string in pixels from the start to
- * getEndIndex.  Then move the pen by (desiredPixelWidth -
- * widthToAlignmentPoint) before drawing the text.  It also works
- * where there is no decimal, but possibly additional characters at
- * the end, e.g. with parentheses in negative numbers: "(12)" for -12.
- * <p>
- * <em>User subclasses are not supported.</em> While clients may write
- * subclasses, such code will not necessarily work and will not be
- * guaranteed to work stably from release to release.

-/**
- * \file
- * \brief Basic types for the platform.
- *
- * This file used to be generated by autoconf/configure.
- * Starting with ICU 49, platform.h is a normal source file,
- * to simplify cross-compiling and working with non-autoconf/make build systems.
- *
- * When a value in this file does not work on a platform, then please
- * try to derive it from the U_PLATFORM value
- * (for which we might need a new value constant in rare cases)
- * and/or from other macros that are predefined by the compiler
- * or defined in standard (POSIX or platform or compiler) headers.
- *
- * As a temporary workaround, you can add an explicit \#define for some macros
- * before it is first tested, or add an equivalent -D macro definition
- * to the compiler's command line.
- *
- * Note: Some compilers provide ways to show the predefined macros.
- * For example, with gcc you can compile an empty .c file and have the compiler
- * print the predefined macros with
- * \code
- * gcc -E -dM -x c /dev/null | sort
- * \endcode
- * (You can provide an actual empty .c file rather than /dev/null.
- * <code>-x c++</code> is for C++.)

- * and hard to deal with variants of platforms.

- * Starting with ICU 49, we define platforms as numeric macros,
- * with ranges of values for related platforms and their variants.
- * The U_PLATFORM macro is set to one of these values.

- * Historical note from the Solaris Wikipedia article:
- * AT&T and Sun collaborated on a project to merge the most popular Unix variants
- * on the market at that time: BSD, System V, and Xenix.
- * This became Unix System V Release 4 (SVR4).

-/**
- * <p>
- * <code>PluralFormat</code> supports the creation of internationalized
- * messages with plural inflection. It is based on <i>plural
- * selection</i>, i.e. the caller specifies messages for each
- * plural case that can appear in the user's language and the
- * <code>PluralFormat</code> selects the appropriate message based on
- * the number.
- * </p>
- * <h4>The Problem of Plural Forms in Internationalized Messages</h4>
- * <p>
- * Different languages have different ways to inflect
- * plurals. Creating internationalized messages that include plural
- * forms is only feasible when the framework is able to handle plural
- * forms of <i>all</i> languages correctly. <code>ChoiceFormat</code>
- * doesn't handle this well, because it attaches a number interval to
- * each message and selects the message whose interval contains a
- * given number. This can only handle a finite number of
- * intervals. But in some languages, like Polish, one plural case
- * applies to infinitely many intervals (e.g., the plural case applies to
- * numbers ending with 2, 3, or 4 except those ending with 12, 13, or
- * 14). Thus <code>ChoiceFormat</code> is not adequate.
- * </p><p>
- * <code>PluralFormat</code> deals with this by breaking the problem
- * into two parts:
- * <ul>
- * <li>It uses <code>PluralRules</code> that can define more complex
- *     conditions for a plural case than just a single interval. These plural
- *     rules define both what plural cases exist in a language, and to
- *     which numbers these cases apply.
- * <li>It provides predefined plural rules for many languages. Thus, the programmer
- *     need not worry about the plural cases of a language and
- *     does not have to define the plural cases; they can simply
- *     use the predefined keywords. The whole plural formatting of messages can
- *     be done using localized patterns from resource bundles. For predefined plural
- *     rules, see the CLDR <i>Language Plural Rules</i> page at
- *    http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
- * </ul>
- * </p>
- * <h4>Usage of <code>PluralFormat</code></h4>
- * <p>Note: Typically, plural formatting is done via <code>MessageFormat</code>
- * with a <code>plural</code> argument type,
- * rather than using a stand-alone <code>PluralFormat</code>.
- * </p><p>
- * This discussion assumes that you use <code>PluralFormat</code> with
- * a predefined set of plural rules. You can create one using one of
- * the constructors that takes a <code>locale</code> object. To
- * specify the message pattern, you can either pass it to the
- * constructor or set it explicitly using the
- * <code>applyPattern()</code> method. The <code>format()</code>
- * method takes a number object and selects the message of the
- * matching plural case. This message will be returned.
- * </p>
- * <h5>Patterns and Their Interpretation</h5>
- * <p>
- * The pattern text defines the message output for each plural case of the
- * specified locale. Syntax:
- * <pre>
- * pluralStyle = [offsetValue] (selector '{' message '}')+
- * offsetValue = "offset:" number
- * selector = explicitValue | keyword
- * explicitValue = '=' number  // adjacent, no white space in between
- * keyword = [^[[:Pattern_Syntax:][:Pattern_White_Space:]]]+
- * message: see {@link MessageFormat}
- * </pre>
- * Pattern_White_Space between syntax elements is ignored, except
- * between the {curly braces} and their sub-message,
- * and between the '=' and the number of an explicitValue.
- *
- * </p><p>
- * There are 6 predefined casekeyword in CLDR/ICU - 'zero', 'one', 'two', 'few', 'many' and
- * 'other'. You always have to define a message text for the default plural case
- * <code>other</code> which is contained in every rule set.
- * If you do not specify a message text for a particular plural case, the
- * message text of the plural case <code>other</code> gets assigned to this
- * plural case.
- * </p><p>
- * When formatting, the input number is first matched against the explicitValue clauses.
- * If there is no exact-number match, then a keyword is selected by calling
- * the <code>PluralRules</code> with the input number <em>minus the offset</em>.
- * (The offset defaults to 0 if it is omitted from the pattern string.)
- * If there is no clause with that keyword, then the "other" clauses is returned.
- * </p><p>
- * An unquoted pound sign (<code>#</code>) in the selected sub-message
- * itself (i.e., outside of arguments nested in the sub-message)
- * is replaced by the input number minus the offset.
- * The number-minus-offset value is formatted using a
- * <code>NumberFormat</code> for the <code>PluralFormat</code>'s locale. If you
- * need special number formatting, you have to use a <code>MessageFormat</code>
- * and explicitly specify a <code>NumberFormat</code> argument.
- * <strong>Note:</strong> That argument is formatting without subtracting the offset!
- * If you need a custom format and have a non-zero offset, then you need to pass the
- * number-minus-offset value as a separate parameter.
- * </p>
- * For a usage example, see the {@link MessageFormat} class documentation.
- *
- * <h4>Defining Custom Plural Rules</h4>
- * <p>If you need to use <code>PluralFormat</code> with custom rules, you can
- * create a <code>PluralRules</code> object and pass it to
- * <code>PluralFormat</code>'s constructor. If you also specify a locale in this
- * constructor, this locale will be used to format the number in the message
- * texts.
- * </p><p>
- * For more information about <code>PluralRules</code>, see
- * {@link PluralRules}.

-/**
- * Defines rules for mapping non-negative numeric values onto a small set of
- * keywords. Rules are constructed from a text description, consisting
- * of a series of keywords and conditions.  The {@link #select} method
- * examines each condition in order and returns the keyword for the
- * first condition that matches the number.  If none match,
- * default rule(other) is returned.
- *
- * For more information, details, and tips for writing rules, see the
- * LDML spec, C.11 Language Plural Rules:
- * http://www.unicode.org/draft/reports/tr35/tr35.html#Language_Plural_Rules
- *
- * Examples:<pre>
- *   "one: n is 1; few: n in 2..4"</pre>
- *  This defines two rules, for 'one' and 'few'.  The condition for
- *  'one' is "n is 1" which means that the number must be equal to
- *  1 for this condition to pass.  The condition for 'few' is
- *  "n in 2..4" which means that the number must be between 2 and
- *  4 inclusive for this condition to pass.  All other numbers
- *  are assigned the keyword "other" by the default rule.
- *  </p><pre>
- *    "zero: n is 0; one: n is 1; zero: n mod 100 in 1..19"</pre>
- *  This illustrates that the same keyword can be defined multiple times.
- *  Each rule is examined in order, and the first keyword whose condition
- *  passes is the one returned.  Also notes that a modulus is applied
- *  to n in the last rule.  Thus its condition holds for 119, 219, 319...
- *  </p><pre>
- *    "one: n is 1; few: n mod 10 in 2..4 and n mod 100 not in 12..14"</pre>
- *  This illustrates conjunction and negation.  The condition for 'few'
- *  has two parts, both of which must be met: "n mod 10 in 2..4" and

- * <li>i to be the integer digits.</li>
- * <li>f to be the visible fractional digits, as an integer.</li>
- * <li>v to be the number of visible fraction digits.</li>

- * The difference between 'in' and 'within' is that 'in' only includes integers in the specified range, while 'within'
- * includes all values. Using 'within' with a range_list consisting entirely of values is the same as using 'in' (it's
- * not an error).
- * </p>

- * An "identifier" is a sequence of characters that do not have the
- * Unicode Pattern_Syntax or Pattern_White_Space properties.

- * same as using 'in' (it's not an error).
- *</p>
- * <p>
- * Keywords
- * could be defined by users or from ICU locale data. There are 6
- * predefined values in ICU - 'zero', 'one', 'two', 'few', 'many' and
- * 'other'. Callers need to check the value of keyword returned by
- * {@link #select} method.
- * </p>
- *
- * Examples:<pre>
- * UnicodeString keyword = pl->select(number);
- * if (keyword== UnicodeString("one") {
- *     ...
- * }
- * else if ( ... )
- * </pre>
- * <strong>Note:</strong><br>
- *  <p>
- *   ICU defines plural rules for many locales based on CLDR <i>Language Plural Rules</i>.

- * The RuleBasedNumberFormat class formats numbers according to a set of rules. This number formatter is
- * typically used for spelling out numeric values in words (e.g., 25,3476 as
- * &quot;twenty-five thousand three hundred seventy-six&quot; or &quot;vingt-cinq mille trois
- * cents soixante-seize&quot; or
- * &quot;f&uuml;nfundzwanzigtausenddreihundertsechsundsiebzig&quot;), but can also be used for
- * other complicated formatting tasks, such as formatting a number of seconds as hours,
- * minutes and seconds (e.g., 3,730 as &quot;1:02:10&quot;).
- *
- * <p>The resources contain three predefined formatters for each locale: spellout, which
- * spells out a value in words (123 is &quot;one hundred twenty-three&quot;); ordinal, which
- * appends an ordinal suffix to the end of a numeral (123 is &quot;123rd&quot;); and
- * duration, which shows a duration in seconds as hours, minutes, and seconds (123 is
- * &quot;2:03&quot;).&nbsp; The client can also define more specialized <tt>RuleBasedNumberFormat</tt>s
- * by supplying programmer-defined rule sets.</p>
- *
- * <p>The behavior of a <tt>RuleBasedNumberFormat</tt> is specified by a textual description
- * that is either passed to the constructor as a <tt>String</tt> or loaded from a resource
- * bundle. In its simplest form, the description consists of a semicolon-delimited list of <em>rules.</em>
- * Each rule has a string of output text and a value or range of values it is applicable to.
- * In a typical spellout rule set, the first twenty rules are the words for the numbers from
- * 0 to 19:</p>
- *
- * <pre>zero; one; two; three; four; five; six; seven; eight; nine;
- * ten; eleven; twelve; thirteen; fourteen; fifteen; sixteen; seventeen; eighteen; nineteen;</pre>
- *
- * <p>For larger numbers, we can use the preceding set of rules to format the ones place, and
- * we only have to supply the words for the multiples of 10:</p>
- *
- * <pre> 20: twenty[-&gt;&gt;];
- * 30: thirty[-&gt;&gt;];
- * 40: forty[-&gt;&gt;];
- * 50: fifty[-&gt;&gt;];
- * 60: sixty[-&gt;&gt;];
- * 70: seventy[-&gt;&gt;];
- * 80: eighty[-&gt;&gt;];
- * 90: ninety[-&gt;&gt;];</pre>
- *
- * <p>In these rules, the <em>base value</em> is spelled out explicitly and set off from the
- * rule's output text with a colon. The rules are in a sorted list, and a rule is applicable
- * to all numbers from its own base value to one less than the next rule's base value. The
- * &quot;&gt;&gt;&quot; token is called a <em>substitution</em> and tells the fomatter to
- * isolate the number's ones digit, format it using this same set of rules, and place the
- * result at the position of the &quot;&gt;&gt;&quot; token. Text in brackets is omitted if
- * the number being formatted is an even multiple of 10 (the hyphen is a literal hyphen; 24
- * is &quot;twenty-four,&quot; not &quot;twenty four&quot;).</p>
- *
- * <p>For even larger numbers, we can actually look up several parts of the number in the
- * list:</p>
- *
- * <pre>100: &lt;&lt; hundred[ &gt;&gt;];</pre>
- *
- * <p>The &quot;&lt;&lt;&quot; represents a new kind of substitution. The &lt;&lt; isolates
- * the hundreds digit (and any digits to its left), formats it using this same rule set, and
- * places the result where the &quot;&lt;&lt;&quot; was. Notice also that the meaning of
- * &gt;&gt; has changed: it now refers to both the tens and the ones digits. The meaning of
- * both substitutions depends on the rule's base value. The base value determines the rule's <em>divisor,</em>
- * which is the highest power of 10 that is less than or equal to the base value (the user
- * can change this). To fill in the substitutions, the formatter divides the number being
- * formatted by the divisor. The integral quotient is used to fill in the &lt;&lt;
- * substitution, and the remainder is used to fill in the &gt;&gt; substitution. The meaning
- * of the brackets changes similarly: text in brackets is omitted if the value being
- * formatted is an even multiple of the rule's divisor. The rules are applied recursively, so
- * if a substitution is filled in with text that includes another substitution, that
- * substitution is also filled in.</p>
- *
- * <p>This rule covers values up to 999, at which point we add another rule:</p>
- *
- * <pre>1000: &lt;&lt; thousand[ &gt;&gt;];</pre>
- *
- * <p>Again, the meanings of the brackets and substitution tokens shift because the rule's
- * base value is a higher power of 10, changing the rule's divisor. This rule can actually be
- * used all the way up to 999,999. This allows us to finish out the rules as follows:</p>
- *
- * <pre> 1,000,000: &lt;&lt; million[ &gt;&gt;];
- * 1,000,000,000: &lt;&lt; billion[ &gt;&gt;];
- * 1,000,000,000,000: &lt;&lt; trillion[ &gt;&gt;];
- * 1,000,000,000,000,000: OUT OF RANGE!;</pre>
- *
- * <p>Commas, periods, and spaces can be used in the base values to improve legibility and
- * are ignored by the rule parser. The last rule in the list is customarily treated as an
- * &quot;overflow rule,&quot; applying to everything from its base value on up, and often (as
- * in this example) being used to print out an error message or default representation.
- * Notice also that the size of the major groupings in large numbers is controlled by the
- * spacing of the rules: because in English we group numbers by thousand, the higher rules
- * are separated from each other by a factor of 1,000.</p>
- *
- * <p>To see how these rules actually work in practice, consider the following example:
- * Formatting 25,430 with this rule set would work like this:</p>
- *
- * <table border="0" width="100%">
- *   <tr>
- *     <td><strong>&lt;&lt; thousand &gt;&gt;</strong></td>
- *     <td>[the rule whose base value is 1,000 is applicable to 25,340]</td>
- *   </tr>

- * <p>The above syntax suffices only to format positive integers. To format negative numbers,
- * we add a special rule:</p>
- *
- * <pre>-x: minus &gt;&gt;;</pre>
- *
- * <p>This is called a <em>negative-number rule,</em> and is identified by &quot;-x&quot;
- * where the base value would be. This rule is used to format all negative numbers. the
- * &gt;&gt; token here means &quot;find the number's absolute value, format it with these
- * rules, and put the result here.&quot;</p>
- *
- * <p>We also add a special rule called a <em>fraction rule </em>for numbers with fractional
- * parts:</p>
- *
- * <pre>x.x: &lt;&lt; point &gt;&gt;;</pre>
- *
- * <p>This rule is used for all positive non-integers (negative non-integers pass through the
- * negative-number rule first and then through this rule). Here, the &lt;&lt; token refers to
- * the number's integral part, and the &gt;&gt; to the number's fractional part. The
- * fractional part is formatted as a series of single-digit numbers (e.g., 123.456 would be
- * formatted as &quot;one hundred twenty-three point four five six&quot;).</p>
- *
- * <p>To see how this rule syntax is applied to various languages, examine the resource data.</p>
- *
- * <p>There is actually much more flexibility built into the rule language than the
- * description above shows. A formatter may own multiple rule sets, which can be selected by
- * the caller, and which can use each other to fill in their substitutions. Substitutions can
- * also be filled in with digits, using a DecimalFormat object. There is syntax that can be
- * used to alter a rule's divisor in various ways. And there is provision for much more
- * flexible fraction handling. A complete description of the rule syntax follows:</p>
- *
- * <hr>
- *
- * <p>The description of a <tt>RuleBasedNumberFormat</tt>'s behavior consists of one or more <em>rule
- * sets.</em> Each rule set consists of a name, a colon, and a list of <em>rules.</em> A rule
- * set name must begin with a % sign. Rule sets with names that begin with a single % sign
- * are <em>public:</em> the caller can specify that they be used to format and parse numbers.
- * Rule sets with names that begin with %% are <em>private:</em> they exist only for the use
- * of other rule sets. If a formatter only has one rule set, the name may be omitted.</p>
- *
- * <p>The user can also specify a special &quot;rule set&quot; named <tt>%%lenient-parse</tt>.
- * The body of <tt>%%lenient-parse</tt> isn't a set of number-formatting rules, but a <tt>RuleBasedCollator</tt>
- * description which is used to define equivalences for lenient parsing. For more information
- * on the syntax, see <tt>RuleBasedCollator</tt>. For more information on lenient parsing,
- * see <tt>setLenientParse()</tt>.  <em>Note:</em> symbols that have syntactic meaning
- * in collation rules, such as '&amp;', have no particular meaning when appearing outside
- * of the <tt>lenient-parse</tt> rule set.</p>
- *
- * <p>The body of a rule set consists of an ordered, semicolon-delimited list of <em>rules.</em>
- * Internally, every rule has a base value, a divisor, rule text, and zero, one, or two <em>substitutions.</em>
- * These parameters are controlled by the description syntax, which consists of a <em>rule
- * descriptor,</em> a colon, and a <em>rule body.</em></p>
- *
- * <p>A rule descriptor can take one of the following forms (text in <em>italics</em> is the
- * name of a token):</p>

- * <p>A rule set may be either a regular rule set or a <em>fraction rule set,</em> depending
- * on whether it is used to format a number's integral part (or the whole number) or a
- * number's fractional part. Using a rule set to format a rule's fractional part makes it a
- * fraction rule set.</p>
- *
- * <p>Which rule is used to format a number is defined according to one of the following
- * algorithms: If the rule set is a regular rule set, do the following:
- *
- * <ul>
- *   <li>If the rule set includes a master rule (and the number was passed in as a <tt>double</tt>),
- *     use the master rule.&nbsp; (If the number being formatted was passed in as a <tt>long</tt>,
- *     the master rule is ignored.)</li>
- *   <li>If the number is negative, use the negative-number rule.</li>
- *   <li>If the number has a fractional part and is greater than 1, use the improper fraction
- *     rule.</li>
- *   <li>If the number has a fractional part and is between 0 and 1, use the proper fraction
- *     rule.</li>
- *   <li>Binary-search the rule list for the rule with the highest base value less than or equal
- *     to the number. If that rule has two substitutions, its base value is not an even multiple
- *     of its divisor, and the number <em>is</em> an even multiple of the rule's divisor, use the
- *     rule that precedes it in the rule list. Otherwise, use the rule itself.</li>
- * </ul>
- *
- * <p>If the rule set is a fraction rule set, do the following:
- *
- * <ul>
- *   <li>Ignore negative-number and fraction rules.</li>
- *   <li>For each rule in the list, multiply the number being formatted (which will always be
- *     between 0 and 1) by the rule's base value. Keep track of the distance between the result
- *     the nearest integer.</li>
- *   <li>Use the rule that produced the result closest to zero in the above calculation. In the
- *     event of a tie or a direct hit, use the first matching rule encountered. (The idea here is
- *     to try each rule's base value as a possible denominator of a fraction. Whichever
- *     denominator produces the fraction closest in value to the number being formatted wins.) If
- *     the rule following the matching rule has the same base value, use it if the numerator of
- *     the fraction is anything other than 1; if the numerator is 1, use the original matching
- *     rule. (This is to allow singular and plural forms of the rule text without a lot of extra
- *     hassle.)</li>
- * </ul>
- *
- * <p>A rule's body consists of a string of characters terminated by a semicolon. The rule
- * may include zero, one, or two <em>substitution tokens,</em> and a range of text in
- * brackets. The brackets denote optional text (and may also include one or both
- * substitutions). The exact meanings of the substitution tokens, and under what conditions
- * optional text is omitted, depend on the syntax of the substitution token and the context.
- * The rest of the text in a rule body is literal text that is output when the rule matches
- * the number being formatted.</p>
- *
- * <p>A substitution token begins and ends with a <em>token character.</em> The token
- * character and the context together specify a mathematical operation to be performed on the
- * number being formatted. An optional <em>substitution descriptor </em>specifies how the
- * value resulting from that operation is used to fill in the substitution. The position of
- * the substitution token in the rule body specifies the location of the resultant text in
- * the original rule text.</p>
- *
- * <p>The meanings of the substitution token characters are as follows:</p>

- * Localization data is represented as a textual description.  The description represents
- * an array of arrays of string.  The first element is an array of the public rule set names,
- * each of these must be one of the public rule set names that appear in the rules.  Only
- * names in this array will be treated as public rule set names by the API.  Each subsequent
- * element is an array of localizations of these names.  The first element of one of these
- * subarrays is the locale name, and the remaining elements are localizations of the
- * public rule set names, in the same order as they were listed in the first arrray.</p>
- * <p>In the syntax, angle brackets '<', '>' are used to delimit the arrays, and comma ',' is used
- * to separate elements of an array.  Whitespace is ignored, unless quoted.</p>
- * <p>For example:<pre>
- * < < %foo, %bar, %baz >,

-/**
- * \file
- * \brief  C++ API:  Regular Expressions
- *
- * The ICU API for processing regular expressions consists of two classes,
- *  `RegexPattern` and `RegexMatcher`.
- *  `RegexPattern` objects represent a pre-processed, or compiled
- *  regular expression.  They are created from a regular expression pattern string,
- *  and can be used to create `RegexMatcher` objects for the pattern.
- *
- * Class `RegexMatcher` bundles together a regular expression
- *  pattern and a target string to which the search pattern will be applied.
- *  `RegexMatcher` includes API for doing plain find or search
- *  operations, for search and replace operations, and for obtaining detailed
- *  information about bounds of a match.
- *
- * Note that by constructing `RegexMatcher` objects directly from regular
- * expression pattern strings application code can be simplified and the explicit
- * need for `RegexPattern` objects can usually be eliminated.

-/**
- * <code>Region</code> is the class representing a Unicode Region Code, also known as a 
- * Unicode Region Subtag, which is defined based upon the BCP 47 standard. We often think of
- * "regions" as "countries" when defining the characteristics of a locale.  Region codes There are different
- * types of region codes that are important to distinguish.
- * <p>
- *  Macroregion - A code for a "macro geographical (continental) region, geographical sub-region, or 
- *  selected economic and other grouping" as defined in 
- *  UN M.49 (http://unstats.un.org/unsd/methods/m49/m49regin.htm). 
- *  These are typically 3-digit codes, but contain some 2-letter codes, such as the LDML code QO 
- *  added for Outlying Oceania.  Not all UNM.49 codes are defined in LDML, but most of them are.
- *  Macroregions are represented in ICU by one of three region types: WORLD ( region code 001 ),
- *  CONTINENTS ( regions contained directly by WORLD ), and SUBCONTINENTS ( things contained directly
- *  by a continent ).
- *  <p>
- *  TERRITORY - A Region that is not a Macroregion. These are typically codes for countries, but also
- *  include areas that are not separate countries, such as the code "AQ" for Antarctica or the code 
- *  "HK" for Hong Kong (SAR China). Overseas dependencies of countries may or may not have separate 
- *  codes. The codes are typically 2-letter codes aligned with the ISO 3166 standard, but BCP47 allows
- *  for the use of 3-digit codes in the future.
- *  <p>
- *  UNKNOWN - The code ZZ is defined by Unicode LDML for use to indicate that the Region is unknown,
- *  or that the value supplied as a region was invalid.
- *  <p>
- *  DEPRECATED - Region codes that have been defined in the past but are no longer in modern usage,
- *  usually due to a country splitting into multiple territories or changing its name.
- *  <p>
- *  GROUPING - A widely understood grouping of territories that has a well defined membership such
- *  that a region code has been assigned for it.  Some of these are UNM.49 codes that do't fall into 
- *  the world/continent/sub-continent hierarchy, while others are just well known groupings that have
- *  their own region code. Region "EU" (European Union) is one such region code that is a grouping.
- *  Groupings will never be returned by the getContainingRegion() API, since a different type of region
- *  ( WORLD, CONTINENT, or SUBCONTINENT ) will always be the containing region instead.
- *
- * The Region class is not intended for public subclassing.

- * // Appends "in 1 day"
- * fmt.format(

- * // Appends "in 3 days"
- * fmt.format(
- *     3, UDAT_DIRECTION_NEXT, UDAT_RELATIVE_DAYS, appendTo, status);
- * // Appends "3.2 years ago"
- * fmt.format(
- *     3.2, UDAT_DIRECTION_LAST, UDAT_RELATIVE_YEARS, appendTo, status);
- * // Appends "last Sunday"
- * fmt.format(UDAT_DIRECTION_LAST, UDAT_ABSOLUTE_SUNDAY, appendTo, status);
- * // Appends "this Sunday"
- * fmt.format(UDAT_DIRECTION_THIS, UDAT_ABSOLUTE_SUNDAY, appendTo, status);
- * // Appends "next Sunday"
- * fmt.format(UDAT_DIRECTION_NEXT, UDAT_ABSOLUTE_SUNDAY, appendTo, status);
- * // Appends "Sunday"
- * fmt.format(UDAT_DIRECTION_PLAIN, UDAT_ABSOLUTE_SUNDAY, appendTo, status);
- *

-/**
- * <code>Replaceable</code> is an abstract base class representing a
- * string of characters that supports the replacement of a range of
- * itself with a new string of characters.  It is used by APIs that
- * change a piece of text while retaining metadata.  Metadata is data
- * other than the Unicode characters returned by char32At().  One
- * example of metadata is style attributes; another is an edit
- * history, marking each character with an author and revision number.
- *
- * <p>An implicit aspect of the <code>Replaceable</code> API is that
- * during a replace operation, new characters take on the metadata of
- * the old characters.  For example, if the string "the <b>bold</b>
- * font" has range (4, 8) replaced with "strong", then it becomes "the
- * <b>strong</b> font".
- *
- * <p><code>Replaceable</code> specifies ranges using a start
- * offset and a limit offset.  The range of characters thus specified
- * includes the characters at offset start..limit-1.  That is, the
- * start offset is inclusive, and the limit offset is exclusive.
- *
- * <p><code>Replaceable</code> also includes API to access characters
- * in the string: <code>length()</code>, <code>charAt()</code>,
- * <code>char32At()</code>, and <code>extractBetween()</code>.
- *
- * <p>For a subclass to support metadata, typical behavior of
- * <code>replace()</code> is the following:
- * <ul>
- *   <li>Set the metadata of the new text to the metadata of the first
- *   character replaced</li>
- *   <li>If no characters are replaced, use the metadata of the
- *   previous character</li>
- *   <li>If there is no previous character (i.e. start == 0), use the
- *   following character</li>
- *   <li>If there is no following character (i.e. the replaceable was
- *   empty), use default metadata.<br>
- *   <li>If the code point U+FFFF is seen, it should be interpreted as
- *   a special marker having no metadata<li>
- *   </li>
- * </ul>
- * If this is not the behavior, the subclass should document any differences.

-* Modification History:
-*
-*   Date        Name        Description
-*   2/5/97      aliu        Added scanForLocaleInFile.  Added
-*                           constructor which attempts to read resource bundle
-*                           from a specific file, without searching other files.
-*   2/11/97     aliu        Added UErrorCode return values to constructors.  Fixed
-*                           infinite loops in scanForFile and scanForLocale.
-*                           Modified getRawResourceData to not delete storage
-*                           in localeData and resourceData which it doesn't own.
-*                           Added Mac compatibility #ifdefs for tellp() and
-*                           ios::nocreate.
-*   2/18/97     helena      Updated with 100% documentation coverage.
-*   3/13/97     aliu        Rewrote to load in entire resource bundle and store
-*                           it as a Hashtable of ResourceBundleData objects.
-*                           Added state table to govern parsing of files.
-*                           Modified to load locale index out of new file
-*                           distinct from default.txt.
-*   3/25/97     aliu        Modified to support 2-d arrays, needed for timezone
-*                           data. Added support for custom file suffixes.  Again,
-*                           needed to support timezone data.
-*   4/7/97      aliu        Cleaned up.
-* 03/02/99      stephen     Removed dependency on FILE*.
-* 03/29/99      helena      Merged Bertrand and Stephen's changes.
-* 06/11/99      stephen     Removed parsing of .txt files.
-*                           Reworked to use new binary format.
-*                           Cleaned up.
-* 06/14/99      stephen     Removed methods taking a filename suffix.
-* 11/09/99      weiv        Added getLocale(), fRealLocale, removed fRealLocaleID

- * locale and then ask it for individual resources.
- * <P>
- * Resource bundles in ICU4C are currently defined using text files which conform to the following
- * <a href="http://source.icu-project.org/repos/icu/icuhtml/trunk/design/bnf_rb.txt">BNF definition</a>.
- * More on resource bundle concepts and syntax can be found in the

-     *                returned by Locale::getDefault()) will be used.

-     * The UErrorCode& err parameter is used to return status information to the user. To
-     * check whether the construction succeeded or not, you should check the value of
-     * U_SUCCESS(err). If you wish more detailed information, you can check for
-     * informational error results which still indicate success. U_USING_FALLBACK_WARNING
-     * indicates that a fall back locale was used. For example, 'de_CH' was requested,

-     * fall back locales could be found.

- * <tt>SearchIterator</tt> is an abstract base class that provides 
- * methods to search for a pattern within a text string. Instances of
- * <tt>SearchIterator</tt> maintain a current position and scans over the 
- * target text, returning the indices the pattern is matched and the length 
- * of each match.
- * <p>
- * <tt>SearchIterator</tt> defines a protocol for text searching. 
- * Subclasses provide concrete implementations of various search algorithms. 
- * For example, <tt>StringSearch</tt> implements language-sensitive pattern 
- * matching based on the comparison rules defined in a 
- * <tt>RuleBasedCollator</tt> object. 
- * <p> 
- * Other options for searching includes using a BreakIterator to restrict 
- * the points at which matches are detected.
- * <p>
- * <tt>SearchIterator</tt> provides an API that is similar to that of
- * other text iteration classes such as <tt>BreakIterator</tt>. Using 
- * this class, it is easy to scan through text looking for all occurances of 
- * a given pattern. The following example uses a <tt>StringSearch</tt> 
- * object to find all instances of "fox" in the target string. Any other 
- * subclass of <tt>SearchIterator</tt> can be used in an identical 
- * manner.
- * <pre><code>
- * UnicodeString target("The quick brown fox jumped over the lazy fox");
- * UnicodeString pattern("fox");
- *
- * SearchIterator *iter  = new StringSearch(pattern, target);

- * for (int pos = iter->first(error); pos != USEARCH_DONE; 
- *                               pos = iter->next(error)) {

-/**
-  * <p><code>SelectFormat</code> supports the creation of  internationalized
-  * messages by selecting phrases based on keywords. The pattern  specifies
-  * how to map keywords to phrases and provides a default phrase. The
-  * object provided to the format method is a string that's matched
-  * against the keywords. If there is a match, the corresponding phrase
-  * is selected; otherwise, the default phrase is used.</p>
-  *
-  * <h4>Using <code>SelectFormat</code> for Gender Agreement</h4>
-  *
-  * <p>Note: Typically, select formatting is done via <code>MessageFormat</code>
-  * with a <code>select</code> argument type,
-  * rather than using a stand-alone <code>SelectFormat</code>.</p>
-  *
-  * <p>The main use case for the select format is gender based  inflection.
-  * When names or nouns are inserted into sentences, their gender can  affect pronouns,
-  * verb forms, articles, and adjectives. Special care needs to be
-  * taken for the case where the gender cannot be determined.
-  * The impact varies between languages:</p>
-  * \htmlonly
-  * <ul>
-  * <li>English has three genders, and unknown gender is handled as a  special
-  * case. Names use the gender of the named person (if known), nouns  referring
-  * to people use natural gender, and inanimate objects are usually  neutral.
-  * The gender only affects pronouns: "he", "she", "it", "they".
-  *
-  * <li>German differs from English in that the gender of nouns is  rather
-  * arbitrary, even for nouns referring to people ("M&#x00E4;dchen", girl, is  neutral).
-  * The gender affects pronouns ("er", "sie", "es"), articles ("der",  "die",
-  * "das"), and adjective forms ("guter Mann", "gute Frau", "gutes  M&#x00E4;dchen").
-  *
-  * <li>French has only two genders; as in German the gender of nouns
-  * is rather arbitrary - for sun and moon, the genders
-  * are the opposite of those in German. The gender affects
-  * pronouns ("il", "elle"), articles ("le", "la"),
-  * adjective forms ("bon", "bonne"), and sometimes
-  * verb forms ("all&#x00E9;", "all&#x00E9;e").
-  *
-  * <li>Polish distinguishes five genders (or noun classes),
-  * human masculine, animate non-human masculine, inanimate masculine,
-  * feminine, and neuter.
-  * </ul>
-  * \endhtmlonly
-  * <p>Some other languages have noun classes that are not related to  gender,
-  * but similar in grammatical use.
-  * Some African languages have around 20 noun classes.</p>
-  *
-  * <p><b>Note:</b>For the gender of a <i>person</i> in a given sentence,
-  * we usually need to distinguish only between female, male and other/unknown.</p>
-  *
-  * <p>To enable localizers to create sentence patterns that take their
-  * language's gender dependencies into consideration, software has to  provide
-  * information about the gender associated with a noun or name to
-  * <code>MessageFormat</code>.
-  * Two main cases can be distinguished:</p>
-  *
-  * <ul>
-  * <li>For people, natural gender information should be maintained  for each person.
-  * Keywords like "male", "female", "mixed" (for groups of people)
-  * and "unknown" could be used.
-  *
-  * <li>For nouns, grammatical gender information should be maintained  for
-  * each noun and per language, e.g., in resource bundles.
-  * The keywords "masculine", "feminine", and "neuter" are commonly  used,
-  * but some languages may require other keywords.
-  * </ul>
-  *
-  * <p>The resulting keyword is provided to <code>MessageFormat</code>  as a
-  * parameter separate from the name or noun it's associated with. For  example,
-  * to generate a message such as "Jean went to Paris", three separate  arguments
-  * would be provided: The name of the person as argument 0, the  gender of
-  * the person as argument 1, and the name of the city as argument 2.
-  * The sentence pattern for English, where the gender of the person has
-  * no impact on this simple sentence, would not refer to argument 1  at all:</p>
-  *
-  * <pre>{0} went to {2}.</pre>
-  *
-  * <p><b>Note:</b> The entire sentence should be included (and partially repeated)
-  * inside each phrase. Otherwise translators would have to be trained on how to
-  * move bits of the sentence in and out of the select argument of a message.
-  * (The examples below do not follow this recommendation!)</p>
-  *
-  * <p>The sentence pattern for French, where the gender of the person affects
-  * the form of the participle, uses a select format based on argument 1:</p>
-  *
-  * \htmlonly<pre>{0} est {1, select, female {all&#x00E9;e} other {all&#x00E9;}} &#x00E0; {2}.</pre>\endhtmlonly
-  *
-  * <p>Patterns can be nested, so that it's possible to handle  interactions of
-  * number and gender where necessary. For example, if the above  sentence should
-  * allow for the names of several people to be inserted, the  following sentence
-  * pattern can be used (with argument 0 the list of people's names,
-  * argument 1 the number of people, argument 2 their combined gender, and
-  * argument 3 the city name):</p>
-  *
-  * \htmlonly
-  * <pre>{0} {1, plural,
-  *                 one {est {2, select, female {all&#x00E9;e} other  {all&#x00E9;}}}
-  *                 other {sont {2, select, female {all&#x00E9;es} other {all&#x00E9;s}}}
-  *          }&#x00E0; {3}.</pre>
-  * \endhtmlonly
-  *
-  * <h4>Patterns and Their Interpretation</h4>
-  *
-  * <p>The <code>SelectFormat</code> pattern string defines the phrase output
-  * for each user-defined keyword.
-  * The pattern is a sequence of (keyword, message) pairs.
-  * A keyword is a "pattern identifier": [^[[:Pattern_Syntax:][:Pattern_White_Space:]]]+</p>
-  *
-  * <p>Each message is a MessageFormat pattern string enclosed in {curly braces}.</p>
-  *
-  * <p>You always have to define a phrase for the default keyword
-  * <code>other</code>; this phrase is returned when the keyword
-  * provided to
-  * the <code>format</code> method matches no other keyword.
-  * If a pattern does not provide a phrase for <code>other</code>, the  method
-  * it's provided to returns the error  <code>U_DEFAULT_KEYWORD_MISSING</code>.
-  * <br>
-  * Pattern_White_Space between keywords and messages is ignored.
-  * Pattern_White_Space within a message is preserved and output.</p>
-  *
-  * <p><pre>Example:
-  * \htmlonly
-  *
-  * UErrorCode status = U_ZERO_ERROR;
-  * MessageFormat *msgFmt = new MessageFormat(UnicodeString("{0} est  {1, select, female {all&#x00E9;e} other {all&#x00E9;}} &#x00E0; Paris."), Locale("fr"),  status);
-  * if (U_FAILURE(status)) {
-  *       return;
-  * }
-  * FieldPosition ignore(FieldPosition::DONT_CARE);
-  * UnicodeString result;
-  *
-  * char* str1= "Kirti,female";
-  * Formattable args1[] = {"Kirti","female"};
-  * msgFmt->format(args1, 2, result, ignore, status);
-  * cout << "Input is " << str1 << " and result is: " << result << endl;
-  * delete msgFmt;
-  *
-  * \endhtmlonly
-  * </pre>
-  * </p>
-  *
-  * Produces the output:<br>
-  * \htmlonly
-  * <code>Kirti est all&#x00E9;e &#x00E0; Paris.</code>
-  * \endhtmlonly

-/**
- *
- * SimpleDateFormat is a concrete class for formatting and parsing dates in a
- * language-independent manner. It allows for formatting (millis -> text),
- * parsing (text -> millis), and normalization. Formats/Parses a date or time,
- * which is the standard milliseconds since 24:00 GMT, Jan 1, 1970.
- * <P>
- * Clients are encouraged to create a date-time formatter using DateFormat::getInstance(),
- * getDateInstance(), getDateInstance(), or getDateTimeInstance() rather than
- * explicitly constructing an instance of SimpleDateFormat.  This way, the client
- * is guaranteed to get an appropriate formatting pattern for whatever locale the
- * program is running in.  However, if the client needs something more unusual than
- * the default patterns in the locales, he can construct a SimpleDateFormat directly
- * and give it an appropriate pattern (or use one of the factory methods on DateFormat
- * and modify the pattern after the fact with toPattern() and applyPattern().
- *
- * <p><strong>Date and Time Patterns:</strong></p>
- *
- * <p>Date and time formats are specified by <em>date and time pattern</em> strings.
- * Within date and time pattern strings, all unquoted ASCII letters [A-Za-z] are reserved
- * as pattern letters representing calendar fields. <code>SimpleDateFormat</code> supports
- * the date and time formatting algorithm and pattern letters defined by
- * <a href="http://www.unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table">UTS#35
- * Unicode Locale Data Markup Language (LDML)</a> and further documented for ICU in the
- * <a href="https://sites.google.com/site/icuprojectuserguide/formatparse/datetime?pli=1#TOC-Date-Field-Symbol-Table">ICU
- * User Guide</a>. The following pattern letters are currently available (note that the actual
- * values depend on CLDR and may change from the examples shown here):</p>

- * \endcode
- * </pre>
- * Code Sample:
- * <pre>
- * \code
- *     UErrorCode success = U_ZERO_ERROR;
- *     SimpleTimeZone* pdt = new SimpleTimeZone(-8 * 60 * 60 * 1000, "PST");
- *     pdt->setStartRule( Calendar::APRIL, 1, Calendar::SUNDAY, 2*60*60*1000);
- *     pdt->setEndRule( Calendar::OCTOBER, -1, Calendar::SUNDAY, 2*60*60*1000);
- *
- *     // Format the current time.
- *     SimpleDateFormat* formatter
- *         = new SimpleDateFormat ("yyyy.MM.dd G 'at' hh:mm:ss a zzz", success );
- *     GregorianCalendar cal(success);
- *     UDate currentTime_1 = cal.getTime(success);
- *     FieldPosition fp(FieldPosition::DONT_CARE);
- *     UnicodeString dateString;
- *     formatter->format( currentTime_1, dateString, fp );
- *     cout << "result: " << dateString << endl;
- *
- *     // Parse the previous string back into a Date.
- *     ParsePosition pp(0);
- *     UDate currentTime_2 = formatter->parse(dateString, pp );
- * \endcode
- * </pre>
- * In the above example, the time value "currentTime_2" obtained from parsing
- * will be equal to currentTime_1. However, they may not be equal if the am/pm
- * marker 'a' is left out from the format pattern while the "hour in am/pm"
- * pattern symbol is used. This information loss can happen when formatting the
- * time in PM.
- *
- * <p>
- * When parsing a date string using the abbreviated year pattern ("y" or "yy"),
- * SimpleDateFormat must interpret the abbreviated year
- * relative to some century.  It does this by adjusting dates to be
- * within 80 years before and 20 years after the time the SimpleDateFormat
- * instance is created. For example, using a pattern of "MM/dd/yy" and a
- * SimpleDateFormat instance created on Jan 1, 1997,  the string
- * "01/11/12" would be interpreted as Jan 11, 2012 while the string "05/04/64"
- * would be interpreted as May 4, 1964.
- * During parsing, only strings consisting of exactly two digits, as defined by
- * <code>Unicode::isDigit()</code>, will be parsed into the default century.
- * Any other numeric string, such as a one digit string, a three or more digit
- * string, or a two digit string that isn't all digits (for example, "-1"), is
- * interpreted literally.  So "01/02/3" or "01/02/003" are parsed (for the
- * Gregorian calendar), using the same pattern, as Jan 2, 3 AD.  Likewise (but
- * only in lenient parse mode, the default) "01/02/-3" is parsed as Jan 2, 4 BC.
- *
- * <p>
- * If the year pattern has more than two 'y' characters, the year is
- * interpreted literally, regardless of the number of digits.  So using the
- * pattern "MM/dd/yyyy", "01/11/12" parses to Jan 11, 12 A.D.
- *
- * <p>
- * When numeric fields abut one another directly, with no intervening delimiter
- * characters, they constitute a run of abutting numeric fields.  Such runs are
- * parsed specially.  For example, the format "HHmmss" parses the input text
- * "123456" to 12:34:56, parses the input text "12345" to 1:23:45, and fails to
- * parse "1234".  In other words, the leftmost field of the run is flexible,
- * while the others keep a fixed width.  If the parse fails anywhere in the run,
- * then the leftmost field is shortened by one character, and the entire run is
- * parsed again. This is repeated until either the parse succeeds or the
- * leftmost field is one character in length.  If the parse still fails at that
- * point, the parse of the run fails.
- *
- * <P>
- * For time zones that have no names, SimpleDateFormat uses strings GMT+hours:minutes or
- * GMT-hours:minutes.
- * <P>
- * The calendar defines what is the first day of the week, the first week of the
- * year, whether hours are zero based or not (0 vs 12 or 24), and the timezone.
- * There is one common number format to handle all the numbers; the digit count
- * is handled programmatically according to the pattern.
- *
- * <p><em>User subclasses are not supported.</em> While clients may write
- * subclasses, such code will not necessarily work and will not be
- * guaranteed to work stably from release to release.

-/**
- *
- * Collation keys are generated by the Collator class.  Use the CollationKey objects
- * instead of Collator to compare strings multiple times.  A CollationKey
- * preprocesses the comparison information from the Collator object to
- * make the comparison faster.  If you are not going to comparing strings
- * multiple times, then using the Collator object is generally faster,
- * since it only processes as much of the string as needed to make a
- * comparison.
- * <p> For example (with strength == tertiary)
- * <p>When comparing "Abernathy" to "Baggins-Smythworthy", Collator
- * only needs to process a couple of characters, while a comparison
- * with CollationKeys will process all of the characters.  On the other hand,
- * if you are doing a sort of a number of fields, it is much faster to use
- * CollationKeys, since you will be comparing strings multiple times.
- * <p>Typical use of CollationKeys are in databases, where you store a CollationKey
- * in a hidden field, and use it for sorting or indexing.
- *
- * <p>Example of use:
- * <pre>
- * \code
- *     UErrorCode success = U_ZERO_ERROR;
- *     Collator* myCollator = Collator::createInstance(success);
- *     CollationKey* keys = new CollationKey [3];
- *     myCollator->getCollationKey("Tom", keys[0], success );
- *     myCollator->getCollationKey("Dick", keys[1], success );
- *     myCollator->getCollationKey("Harry", keys[2], success );
- *
- *     // Inside body of sort routine, compare keys this way:
- *     CollationKey tmp;
- *     if(keys[0].compareTo( keys[1] ) > 0 ) {
- *         tmp = keys[0]; keys[0] = keys[1]; keys[1] = tmp;
- *     }
- *     //...
- * \endcode
- * </pre>
- * <p>Because Collator::compare()'s algorithm is complex, it is faster to sort
- * long lists of words by retrieving collation keys with Collator::getCollationKey().
- * You can then cache the collation keys and compare them using CollationKey::compareTo().
- * <p>
- * <strong>Note:</strong> <code>Collator</code>s with different Locale,
- * CollationStrength and DecompositionMode settings will return different
- * CollationKeys for the same set of strings. Locales have specific
- * collation rules, and the way in which secondary and tertiary differences
- * are taken into account, for example, will result in different CollationKeys
- * for same strings.
- * <p>

-/**
- * Base class for 'pure' C++ implementations of uenum api.  Adds a
- * method that returns the next UnicodeString since in C++ this can
- * be a common storage format for strings.
- *
- * <p>The model is that the enumeration is over strings maintained by
- * a 'service.'  At any point, the service might change, invalidating
- * the enumerator (though this is expected to be rare).  The iterator
- * returns an error if this has occurred.  Lack of the error is no
- * guarantee that the service didn't change immediately after the
- * call, so the returned string still might not be 'valid' on
- * subsequent use.</p>
- *
- * <p>Strings may take the form of const char*, const char16_t*, or const
- * UnicodeString*.  The type you get is determine by the variant of
- * 'next' that you call.  In general the StringEnumeration is
- * optimized for one of these types, but all StringEnumerations can
- * return all types.  Returned strings are each terminated with a NUL.
- * Depending on the service data, they might also include embedded NUL
- * characters, so API is provided to optionally return the true
- * length, counting the embedded NULs but not counting the terminating
- * NUL.</p>
- *
- * <p>The pointers returned by next, unext, and snext become invalid
- * upon any subsequent call to the enumeration's destructor, next,
- * unext, snext, or reset.</p>
- *
- * ICU 2.8 adds some default implementations and helper functions
- * for subclasses.

-         * Branch nodes in this trie data structure are not symmetric.
-         * Most branch edges "jump" to other nodes but the rightmost branch edges
-         * just continue without a jump.
-         * Therefore, write() must write the rightmost branch edge last
-         * (trie units are written backwards), and must write it at that point even if
-         * it is a duplicate of a node previously written elsewhere.
-         *
-         * This function visits and marks right branch edges first.
-         * Edges are numbered with increasingly negative values because we share the
-         * offset field which gets positive values when nodes are written.
-         * A branch edge also remembers the first number for any of its edges.
-         *
-         * When a further-left branch edge has a number in the range of the rightmost
-         * edge's numbers, then it will be written as part of the required right edge
-         * and we can avoid writing it first.
-         *
-         * After root.markRightEdgesFirst(-1) the offsets of all nodes are negative
-         * edge numbers.

-/** 
- *
- * <tt>StringSearch</tt> is a <tt>SearchIterator</tt> that provides
- * language-sensitive text searching based on the comparison rules defined
- * in a {@link RuleBasedCollator} object.
- * StringSearch ensures that language eccentricity can be
- * handled, e.g. for the German collator, characters &szlig; and SS will be matched
- * if case is chosen to be ignored.
- * See the <a href="http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm">
- * "ICU Collation Design Document"</a> for more information.
- * <p>
- * There are 2 match options for selection:<br>
- * Let S' be the sub-string of a text string S between the offsets start and
- * end [start, end].
- * <br>
- * A pattern string P matches a text string S at the offsets [start, end]
- * if
- * <pre> 
- * option 1. Some canonical equivalent of P matches some canonical equivalent
- *           of S'
- * option 2. P matches S' and if P starts or ends with a combining mark,
- *           there exists no non-ignorable combining mark before or after S?
- *           in S respectively.
- * </pre>
- * Option 2. will be the default.
- * <p>
- * This search has APIs similar to that of other text iteration mechanisms 
- * such as the break iterators in <tt>BreakIterator</tt>. Using these 
- * APIs, it is easy to scan through text looking for all occurrences of 
- * a given pattern. This search iterator allows changing of direction by 
- * calling a <tt>reset</tt> followed by a <tt>next</tt> or <tt>previous</tt>.
- * Though a direction change can occur without calling <tt>reset</tt> first,
- * this operation comes with some speed penalty.
- * Match results in the forward direction will match the result matches in
- * the backwards direction in the reverse order
- * <p>
- * <tt>SearchIterator</tt> provides APIs to specify the starting position
- * within the text string to be searched, e.g. <tt>setOffset</tt>,
- * <tt>preceding</tt> and <tt>following</tt>. Since the
- * starting position will be set as it is specified, please take note that
- * there are some danger points which the search may render incorrect
- * results:
- * <ul>
- * <li> The midst of a substring that requires normalization.
- * <li> If the following match is to be found, the position should not be the
- *      second character which requires to be swapped with the preceding
- *      character. Vice versa, if the preceding match is to be found,
- *      position to search from should not be the first character which
- *      requires to be swapped with the next character. E.g certain Thai and
- *      Lao characters require swapping.
- * <li> If a following pattern match is to be found, any position within a
- *      contracting sequence except the first will fail. Vice versa if a
- *      preceding pattern match is to be found, a invalid starting point
- *      would be any character within a contracting sequence except the last.
- * </ul>
- * <p>
- * A <tt>BreakIterator</tt> can be used if only matches at logical breaks are desired.
- * Using a <tt>BreakIterator</tt> will only give you results that exactly matches the
- * boundaries given by the breakiterator. For instance the pattern "e" will
- * not be found in the string "\u00e9" if a character break iterator is used.
- * <p>
- * Options are provided to handle overlapping matches.
- * E.g. In English, overlapping matches produces the result 0 and 2
- * for the pattern "abab" in the text "ababab", where else mutually
- * exclusive matches only produce the result of 0.
- * <p>
- * Though collator attributes will be taken into consideration while
- * performing matches, there are no APIs here for setting and getting the
- * attributes. These attributes can be set by getting the collator
- * from <tt>getCollator</tt> and using the APIs in <tt>coll.h</tt>.
- * Lastly to update <tt>StringSearch</tt> to the new collator attributes,
- * <tt>reset</tt> has to be called.
- * <p> 
- * Restriction: <br>
- * Currently there are no composite characters that consists of a
- * character with combining class > 0 before a character with combining
- * class == 0. However, if such a character exists in the future,
- * <tt>StringSearch</tt> does not guarantee the results for option 1.
- * <p>
- * Consult the <tt>SearchIterator</tt> documentation for information on
- * and examples of how to use instances of this class to implement text
- * searching.
- * <pre><code>
- * UnicodeString target("The quick brown fox jumps over the lazy dog.");
- * UnicodeString pattern("fox");
- *
- * UErrorCode      error = U_ZERO_ERROR;
- * StringSearch iter(pattern, target, Locale::getUS(), NULL, status);
- * for (int pos = iter.first(error);
- *      pos != USEARCH_DONE; 
- *      pos = iter.next(error))
- * {
- *     printf("Found match at %d pos, length is %d\n", pos, iter.getMatchedLength());
- * }
- * </code></pre>
- * <p>
- * Note, <tt>StringSearch</tt> is not to be subclassed.

- * An interface that defines both lookup protocol and parsing of

- *
- * <p>A symbol table maintains two kinds of mappings.  The first is
- * between symbolic names and their values.  For example, if the
- * variable with the name "start" is set to the value "alpha"
- * (perhaps, though not necessarily, through an expression such as
- * "$start=alpha"), then the call lookup("start") will return the
- * char[] array ['a', 'l', 'p', 'h', 'a'].
- *
- * <p>The second kind of mapping is between character values and
- * UnicodeMatcher objects.  This is used by RuleBasedTransliterator,
- * which uses characters in the private use area to represent objects
- * such as UnicodeSets.  If U+E015 is mapped to the UnicodeSet [a-z],
- * then lookupMatcher(0xE015) will return the UnicodeSet [a-z].
- *
- * <p>Finally, a symbol table defines parsing behavior for symbolic
- * names.  All symbolic names start with the SYMBOL_REF character.
- * When a parser encounters this character, it calls parseReference()
- * with the position immediately following the SYMBOL_REF.  The symbol
- * table parses the name, if there is one, and returns it.

-*                          and streamOut methods use istream and ostream objects
-*                          in binary mode.
-*  2/12/97     aliu        Modified to use TableCollationData sub-object to
-*                          hold invariant data.
-*  2/13/97     aliu        Moved several methods into this class from Collation.
-*                          Added a private RuleBasedCollator(Locale&) constructor,
-*                          to be used by Collator::createDefault().  General
-*                          clean up.

-*                          constructor and getDynamicClassID.
-*  3/5/97      aliu        Modified constructFromFile() to add parameter
-*                          specifying whether or not binary loading is to be
-*                          attempted.  This is required for dynamic rule loading.
-* 05/07/97     helena      Added memory allocation error detection.
-*  6/17/97     helena      Added IDENTICAL strength for compare, changed getRules to
-*                          use MergeCollation::getPattern.
-*  6/20/97     helena      Java class name change.
-*  8/18/97     helena      Added internal API documentation.

-/**
- *
- * <code>TimeZone</code> represents a time zone offset, and also figures out daylight
- * savings.
- *
- * <p>
- * Typically, you get a <code>TimeZone</code> using <code>createDefault</code>
- * which creates a <code>TimeZone</code> based on the time zone where the program
- * is running. For example, for a program running in Japan, <code>createDefault</code>
- * creates a <code>TimeZone</code> object based on Japanese Standard Time.
- *
- * <p>
- * You can also get a <code>TimeZone</code> using <code>createTimeZone</code> along
- * with a time zone ID. For instance, the time zone ID for the US Pacific
- * Time zone is "America/Los_Angeles". So, you can get a Pacific Time <code>TimeZone</code> object
- * with:
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * TimeZone *tz = TimeZone::createTimeZone("America/Los_Angeles");
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * You can use the <code>createEnumeration</code> method to iterate through
- * all the supported time zone IDs, or the <code>getCanonicalID</code> method to check
- * if a time zone ID is supported or not.  You can then choose a
- * supported ID to get a <code>TimeZone</code>.
- * If the time zone you want is not represented by one of the
- * supported IDs, then you can create a custom time zone ID with
- * the following syntax:
- *
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * GMT[+|-]hh[[:]mm]
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * For example, you might specify GMT+14:00 as a custom
- * time zone ID.  The <code>TimeZone</code> that is returned
- * when you specify a custom time zone ID uses the specified
- * offset from GMT(=UTC) and does not observe daylight saving
- * time. For example, you might specify GMT+14:00 as a custom
- * time zone ID to create a TimeZone representing 14 hours ahead
- * of GMT (with no daylight saving time). In addition,
- * <code>getCanonicalID</code> can also be used to
- * normalize a custom time zone ID.
- *
- * TimeZone is an abstract class representing a time zone.  A TimeZone is needed for
- * Calendar to produce local time for a particular time zone.  A TimeZone comprises
- * three basic pieces of information:
- * <ul>
- *    <li>A time zone offset; that, is the number of milliseconds to add or subtract
- *      from a time expressed in terms of GMT to convert it to the same time in that
- *      time zone (without taking daylight savings time into account).</li>
- *    <li>Logic necessary to take daylight savings time into account if daylight savings
- *      time is observed in that time zone (e.g., the days and hours on which daylight
- *      savings time begins and ends).</li>
- *    <li>An ID.  This is a text string that uniquely identifies the time zone.</li>
- * </ul>
- *
- * (Only the ID is actually implemented in TimeZone; subclasses of TimeZone may handle
- * daylight savings time and GMT offset in different ways.  Currently we have the following
- * TimeZone subclasses: RuleBasedTimeZone, SimpleTimeZone, and VTimeZone.)
- * <P>
- * The TimeZone class contains a static list containing a TimeZone object for every
- * combination of GMT offset and daylight-savings time rules currently in use in the
- * world, each with a unique ID.  Each ID consists of a region (usually a continent or
- * ocean) and a city in that region, separated by a slash, (for example, US Pacific
- * Time is "America/Los_Angeles.")  Because older versions of this class used
- * three- or four-letter abbreviations instead, there is also a table that maps the older
- * abbreviations to the newer ones (for example, "PST" maps to "America/Los_Angeles").
- * Anywhere the API requires an ID, you can use either form.
- * <P>
- * To create a new TimeZone, you call the factory function TimeZone::createTimeZone()
- * and pass it a time zone ID.  You can use the createEnumeration() function to
- * obtain a list of all the time zone IDs recognized by createTimeZone().
- * <P>
- * You can also use TimeZone::createDefault() to create a TimeZone.  This function uses
- * platform-specific APIs to produce a TimeZone for the time zone corresponding to
- * the client's computer's physical location.  For example, if you're in Japan (assuming
- * your machine is set up correctly), TimeZone::createDefault() will return a TimeZone
- * for Japanese Standard Time ("Asia/Tokyo").

-/**
- *
- * <code>Transliterator</code> is an abstract class that
- * transliterates text from one format to another.  The most common
- * kind of transliterator is a script, or alphabet, transliterator.
- * For example, a Russian to Latin transliterator changes Russian text
- * written in Cyrillic characters to phonetically equivalent Latin
- * characters.  It does not <em>translate</em> Russian to English!
- * Transliteration, unlike translation, operates on characters, without
- * reference to the meanings of words and sentences.
- *
- * <p>Although script conversion is its most common use, a
- * transliterator can actually perform a more general class of tasks.
- * In fact, <code>Transliterator</code> defines a very general API
- * which specifies only that a segment of the input text is replaced
- * by new text.  The particulars of this conversion are determined
- * entirely by subclasses of <code>Transliterator</code>.
- *
- * <p><b>Transliterators are stateless</b>
- *
- * <p><code>Transliterator</code> objects are <em>stateless</em>; they
- * retain no information between calls to
- * <code>transliterate()</code>.  (However, this does <em>not</em>
- * mean that threads may share transliterators without synchronizing
- * them.  Transliterators are not immutable, so they must be
- * synchronized when shared between threads.)  This might seem to
- * limit the complexity of the transliteration operation.  In
- * practice, subclasses perform complex transliterations by delaying
- * the replacement of text until it is known that no other
- * replacements are possible.  In other words, although the
- * <code>Transliterator</code> objects are stateless, the source text
- * itself embodies all the needed information, and delayed operation
- * allows arbitrary complexity.
- *
- * <p><b>Batch transliteration</b>
- *
- * <p>The simplest way to perform transliteration is all at once, on a
- * string of existing text.  This is referred to as <em>batch</em>
- * transliteration.  For example, given a string <code>input</code>
- * and a transliterator <code>t</code>, the call
- *
- *     String result = t.transliterate(input);
- *
- * will transliterate it and return the result.  Other methods allow
- * the client to specify a substring to be transliterated and to use
- * {@link Replaceable } objects instead of strings, in order to
- * preserve out-of-band information (such as text styles).
- *
- * <p><b>Keyboard transliteration</b>
- *
- * <p>Somewhat more involved is <em>keyboard</em>, or incremental
- * transliteration.  This is the transliteration of text that is
- * arriving from some source (typically the user's keyboard) one
- * character at a time, or in some other piecemeal fashion.
- *
- * <p>In keyboard transliteration, a <code>Replaceable</code> buffer
- * stores the text.  As text is inserted, as much as possible is
- * transliterated on the fly.  This means a GUI that displays the
- * contents of the buffer may show text being modified as each new
- * character arrives.
- *
- * <p>Consider the simple rule-based Transliterator:
- * <pre>
- *     th>{theta}
- *     t>{tau}
- * </pre>
- *
- * When the user types 't', nothing will happen, since the
- * transliterator is waiting to see if the next character is 'h'.  To
- * remedy this, we introduce the notion of a cursor, marked by a '|'
- * in the output string:
- * <pre>
- *     t>|{tau}
- *     {tau}h>{theta}
- * </pre>
- *
- * Now when the user types 't', tau appears, and if the next character
- * is 'h', the tau changes to a theta.  This is accomplished by
- * maintaining a cursor position (independent of the insertion point,
- * and invisible in the GUI) across calls to
- * <code>transliterate()</code>.  Typically, the cursor will
- * be coincident with the insertion point, but in a case like the one
- * above, it will precede the insertion point.
- *
- * <p>Keyboard transliteration methods maintain a set of three indices
- * that are updated with each call to
- * <code>transliterate()</code>, including the cursor, start,
- * and limit.  Since these indices are changed by the method, they are
- * passed in an <code>int[]</code> array. The <code>START</code> index
- * marks the beginning of the substring that the transliterator will
- * look at.  It is advanced as text becomes committed (but it is not
- * the committed index; that's the <code>CURSOR</code>).  The
- * <code>CURSOR</code> index, described above, marks the point at
- * which the transliterator last stopped, either because it reached
- * the end, or because it required more characters to disambiguate
- * between possible inputs.  The <code>CURSOR</code> can also be
- * explicitly set by rules in a rule-based Transliterator.
- * Any characters before the <code>CURSOR</code> index are frozen;
- * future keyboard transliteration calls within this input sequence
- * will not change them.  New text is inserted at the
- * <code>LIMIT</code> index, which marks the end of the substring that
- * the transliterator looks at.
- *
- * <p>Because keyboard transliteration assumes that more characters
- * are to arrive, it is conservative in its operation.  It only
- * transliterates when it can do so unambiguously.  Otherwise it waits
- * for more characters to arrive.  When the client code knows that no
- * more characters are forthcoming, perhaps because the user has
- * performed some input termination operation, then it should call
- * <code>finishTransliteration()</code> to complete any
- * pending transliterations.
- *
- * <p><b>Inverses</b>
- *
- * <p>Pairs of transliterators may be inverses of one another.  For
- * example, if transliterator <b>A</b> transliterates characters by
- * incrementing their Unicode value (so "abc" -> "def"), and
- * transliterator <b>B</b> decrements character values, then <b>A</b>
- * is an inverse of <b>B</b> and vice versa.  If we compose <b>A</b>
- * with <b>B</b> in a compound transliterator, the result is the
- * indentity transliterator, that is, a transliterator that does not
- * change its input text.
- *
- * The <code>Transliterator</code> method <code>getInverse()</code>
- * returns a transliterator's inverse, if one exists, or
- * <code>null</code> otherwise.  However, the result of
- * <code>getInverse()</code> usually will <em>not</em> be a true
- * mathematical inverse.  This is because true inverse transliterators
- * are difficult to formulate.  For example, consider two
- * transliterators: <b>AB</b>, which transliterates the character 'A'
- * to 'B', and <b>BA</b>, which transliterates 'B' to 'A'.  It might
- * seem that these are exact inverses, since
- *
- * \htmlonly<blockquote>\endhtmlonly"A" x <b>AB</b> -> "B"<br>
- * "B" x <b>BA</b> -> "A"\htmlonly</blockquote>\endhtmlonly
- *
- * where 'x' represents transliteration.  However,
- *
- * \htmlonly<blockquote>\endhtmlonly"ABCD" x <b>AB</b> -> "BBCD"<br>
- * "BBCD" x <b>BA</b> -> "AACD"\htmlonly</blockquote>\endhtmlonly
- *
- * so <b>AB</b> composed with <b>BA</b> is not the
- * identity. Nonetheless, <b>BA</b> may be usefully considered to be
- * <b>AB</b>'s inverse, and it is on this basis that
- * <b>AB</b><code>.getInverse()</code> could legitimately return
- * <b>BA</b>.
- *
- * <p><b>IDs and display names</b>
- *
- * <p>A transliterator is designated by a short identifier string or
- * <em>ID</em>.  IDs follow the format <em>source-destination</em>,
- * where <em>source</em> describes the entity being replaced, and
- * <em>destination</em> describes the entity replacing
- * <em>source</em>.  The entities may be the names of scripts,
- * particular sequences of characters, or whatever else it is that the
- * transliterator converts to or from.  For example, a transliterator
- * from Russian to Latin might be named "Russian-Latin".  A
- * transliterator from keyboard escape sequences to Latin-1 characters
- * might be named "KeyboardEscape-Latin1".  By convention, system
- * entity names are in English, with the initial letters of words
- * capitalized; user entity names may follow any format so long as
- * they do not contain dashes.
- *
- * <p>In addition to programmatic IDs, transliterator objects have
- * display names for presentation in user interfaces, returned by
- * {@link #getDisplayName }.
- *
- * <p><b>Factory methods and registration</b>
- *
- * <p>In general, client code should use the factory method
- * {@link #createInstance } to obtain an instance of a
- * transliterator given its ID.  Valid IDs may be enumerated using
- * <code>getAvailableIDs()</code>.  Since transliterators are mutable,
- * multiple calls to {@link #createInstance } with the same ID will
- * return distinct objects.
- *
- * <p>In addition to the system transliterators registered at startup,
- * user transliterators may be registered by calling
- * <code>registerInstance()</code> at run time.  A registered instance
- * acts a template; future calls to {@link #createInstance } with the ID
- * of the registered object return clones of that object.  Thus any
- * object passed to <tt>registerInstance()</tt> must implement
- * <tt>clone()</tt> propertly.  To register a transliterator subclass
- * without instantiating it (until it is needed), users may call
- * {@link #registerFactory }.  In this case, the objects are
- * instantiated by invoking the zero-argument public constructor of
- * the class.
- *
- * <p><b>Subclassing</b>
- *
- * Subclasses must implement the abstract method
- * <code>handleTransliterate()</code>.  <p>Subclasses should override
- * the <code>transliterate()</code> method taking a
- * <code>Replaceable</code> and the <code>transliterate()</code>
- * method taking a <code>String</code> and <code>StringBuffer</code>
- * if the performance of these methods can be improved over the
- * performance obtained by the default implementations in this class.
- *
- * <p><b>Rule syntax</b>
- *
- * <p>A set of rules determines how to perform translations.
- * Rules within a rule set are separated by semicolons (';').
- * To include a literal semicolon, prefix it with a backslash ('\').
- * Unicode Pattern_White_Space is ignored.
- * If the first non-blank character on a line is '#',
- * the entire line is ignored as a comment.
- *
- * <p>Each set of rules consists of two groups, one forward, and one
- * reverse. This is a convention that is not enforced; rules for one
- * direction may be omitted, with the result that translations in
- * that direction will not modify the source text. In addition,
- * bidirectional forward-reverse rules may be specified for
- * symmetrical transformations.
- *
- * <p>Note: Another description of the Transliterator rule syntax is available in
- * <a href="https://www.unicode.org/reports/tr35/tr35-general.html#Transform_Rules_Syntax">section
- * Transform Rules Syntax of UTS #35: Unicode LDML</a>.
- * The rules are shown there using arrow symbols ← and → and ↔.
- * ICU supports both those and the equivalent ASCII symbols &lt; and &gt; and &lt;&gt;.
- *
- * <p>Rule statements take one of the following forms:
- *
- * <dl>
- *     <dt><code>$alefmadda=\\u0622;</code></dt>
- *     <dd><strong>Variable definition.</strong> The name on the
- *         left is assigned the text on the right. In this example,
- *         after this statement, instances of the left hand name,
- *         &quot;<code>$alefmadda</code>&quot;, will be replaced by
- *         the Unicode character U+0622. Variable names must begin
- *         with a letter and consist only of letters, digits, and
- *         underscores. Case is significant. Duplicate names cause
- *         an exception to be thrown, that is, variables cannot be
- *         redefined. The right hand side may contain well-formed
- *         text of any length, including no text at all (&quot;<code>$empty=;</code>&quot;).
- *         The right hand side may contain embedded <code>UnicodeSet</code>
- *         patterns, for example, &quot;<code>$softvowel=[eiyEIY]</code>&quot;.</dd>
- *     <dt><code>ai&gt;$alefmadda;</code></dt>
- *     <dd><strong>Forward translation rule.</strong> This rule
- *         states that the string on the left will be changed to the
- *         string on the right when performing forward
- *         transliteration.</dd>
- *     <dt><code>ai&lt;$alefmadda;</code></dt>
- *     <dd><strong>Reverse translation rule.</strong> This rule
- *         states that the string on the right will be changed to
- *         the string on the left when performing reverse
- *         transliteration.</dd>
- * </dl>
- *
- * <dl>
- *     <dt><code>ai&lt;&gt;$alefmadda;</code></dt>
- *     <dd><strong>Bidirectional translation rule.</strong> This
- *         rule states that the string on the right will be changed
- *         to the string on the left when performing forward
- *         transliteration, and vice versa when performing reverse
- *         transliteration.</dd>
- * </dl>
- *
- * <p>Translation rules consist of a <em>match pattern</em> and an <em>output
- * string</em>. The match pattern consists of literal characters,
- * optionally preceded by context, and optionally followed by
- * context. Context characters, like literal pattern characters,
- * must be matched in the text being transliterated. However, unlike
- * literal pattern characters, they are not replaced by the output
- * text. For example, the pattern &quot;<code>abc{def}</code>&quot;
- * indicates the characters &quot;<code>def</code>&quot; must be
- * preceded by &quot;<code>abc</code>&quot; for a successful match.
- * If there is a successful match, &quot;<code>def</code>&quot; will
- * be replaced, but not &quot;<code>abc</code>&quot;. The final '<code>}</code>'
- * is optional, so &quot;<code>abc{def</code>&quot; is equivalent to
- * &quot;<code>abc{def}</code>&quot;. Another example is &quot;<code>{123}456</code>&quot;
- * (or &quot;<code>123}456</code>&quot;) in which the literal
- * pattern &quot;<code>123</code>&quot; must be followed by &quot;<code>456</code>&quot;.
- *
- * <p>The output string of a forward or reverse rule consists of
- * characters to replace the literal pattern characters. If the
- * output string contains the character '<code>|</code>', this is
- * taken to indicate the location of the <em>cursor</em> after
- * replacement. The cursor is the point in the text at which the
- * next replacement, if any, will be applied. The cursor is usually
- * placed within the replacement text; however, it can actually be
- * placed into the precending or following context by using the
- * special character '@'. Examples:
- *
- * <pre>
- *     a {foo} z &gt; | @ bar; # foo -&gt; bar, move cursor before a
- *     {foo} xyz &gt; bar @@|; #&nbsp;foo -&gt; bar, cursor between y and z
- * </pre>
- *
- * <p><b>UnicodeSet</b>
- *
- * <p><code>UnicodeSet</code> patterns may appear anywhere that
- * makes sense. They may appear in variable definitions.
- * Contrariwise, <code>UnicodeSet</code> patterns may themselves
- * contain variable references, such as &quot;<code>$a=[a-z];$not_a=[^$a]</code>&quot;,
- * or &quot;<code>$range=a-z;$ll=[$range]</code>&quot;.
- *
- * <p><code>UnicodeSet</code> patterns may also be embedded directly
- * into rule strings. Thus, the following two rules are equivalent:
- *
- * <pre>
- *     $vowel=[aeiou]; $vowel&gt;'*'; # One way to do this
- *     [aeiou]&gt;'*'; # Another way
- * </pre>
- *
- * <p>See {@link UnicodeSet} for more documentation and examples.
- *
- * <p><b>Segments</b>
- *
- * <p>Segments of the input string can be matched and copied to the
- * output string. This makes certain sets of rules simpler and more
- * general, and makes reordering possible. For example:
- *
- * <pre>
- *     ([a-z]) &gt; $1 $1; # double lowercase letters
- *     ([:Lu:]) ([:Ll:]) &gt; $2 $1; # reverse order of Lu-Ll pairs
- * </pre>
- *
- * <p>The segment of the input string to be copied is delimited by
- * &quot;<code>(</code>&quot; and &quot;<code>)</code>&quot;. Up to
- * nine segments may be defined. Segments may not overlap. In the
- * output string, &quot;<code>$1</code>&quot; through &quot;<code>$9</code>&quot;
- * represent the input string segments, in left-to-right order of
- * definition.
- *
- * <p><b>Anchors</b>
- *
- * <p>Patterns can be anchored to the beginning or the end of the text. This is done with the
- * special characters '<code>^</code>' and '<code>$</code>'. For example:
- *
- * <pre>
- *   ^ a&nbsp;&nbsp; &gt; 'BEG_A'; &nbsp;&nbsp;# match 'a' at start of text
- *   &nbsp; a&nbsp;&nbsp; &gt; 'A'; # match other instances of 'a'
- *   &nbsp; z $ &gt; 'END_Z'; &nbsp;&nbsp;# match 'z' at end of text
- *   &nbsp; z&nbsp;&nbsp; &gt; 'Z';&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; # match other instances of 'z'
- * </pre>
- *
- * <p>It is also possible to match the beginning or the end of the text using a <code>UnicodeSet</code>.
- * This is done by including a virtual anchor character '<code>$</code>' at the end of the
- * set pattern. Although this is usually the match chafacter for the end anchor, the set will
- * match either the beginning or the end of the text, depending on its placement. For
- * example:
- *
- * <pre>
- *   $x = [a-z$]; &nbsp;&nbsp;# match 'a' through 'z' OR anchor
- *   $x 1&nbsp;&nbsp;&nbsp; &gt; 2;&nbsp;&nbsp; # match '1' after a-z or at the start
- *   &nbsp;&nbsp; 3 $x &gt; 4; &nbsp;&nbsp;# match '3' before a-z or at the end
- * </pre>
- *
- * <p><b>Example</b>
- *
- * <p>The following example rules illustrate many of the features of
- * the rule language.
- *
- * <table border="0" cellpadding="4">
- *     <tr>
- *         <td style="vertical-align: top;">Rule 1.</td>
- *         <td style="vertical-align: top; write-space: nowrap;"><code>abc{def}&gt;x|y</code></td>
- *     </tr>
- *     <tr>
- *         <td style="vertical-align: top;">Rule 2.</td>
- *         <td style="vertical-align: top; write-space: nowrap;"><code>xyz&gt;r</code></td>
- *     </tr>
- *     <tr>
- *         <td style="vertical-align: top;">Rule 3.</td>
- *         <td style="vertical-align: top; write-space: nowrap;"><code>yz&gt;q</code></td>
- *     </tr>
- * </table>
- *
- * <p>Applying these rules to the string &quot;<code>adefabcdefz</code>&quot;
- * yields the following results:
- *
- * <table border="0" cellpadding="4">
- *     <tr>
- *         <td style="vertical-align: top; write-space: nowrap;"><code>|adefabcdefz</code></td>
- *         <td style="vertical-align: top;">Initial state, no rules match. Advance
- *         cursor.</td>
- *     </tr>
- *     <tr>
- *         <td style="vertical-align: top; write-space: nowrap;"><code>a|defabcdefz</code></td>
- *         <td style="vertical-align: top;">Still no match. Rule 1 does not match
- *         because the preceding context is not present.</td>
- *     </tr>
- *     <tr>
- *         <td style="vertical-align: top; write-space: nowrap;"><code>ad|efabcdefz</code></td>
- *         <td style="vertical-align: top;">Still no match. Keep advancing until
- *         there is a match...</td>
- *     </tr>
- *     <tr>
- *         <td style="vertical-align: top; write-space: nowrap;"><code>ade|fabcdefz</code></td>
- *         <td style="vertical-align: top;">...</td>
- *     </tr>
- *     <tr>

- *         <td style="vertical-align: top;">Rule 1 matches; replace &quot;<code>def</code>&quot;
- *         with &quot;<code>xy</code>&quot; and back up the cursor
- *         to before the '<code>y</code>'.</td>
- *     </tr>
- *     <tr>
- *         <td style="vertical-align: top; write-space: nowrap;"><code>adefabcx|yz</code></td>
- *         <td style="vertical-align: top;">Although &quot;<code>xyz</code>&quot; is
- *         present, rule 2 does not match because the cursor is
- *         before the '<code>y</code>', not before the '<code>x</code>'.
- *         Rule 3 does match. Replace &quot;<code>yz</code>&quot;
- *         with &quot;<code>q</code>&quot;.</td>
- *     </tr>
- *     <tr>
- *         <td style="vertical-align: top; write-space: nowrap;"><code>adefabcxq|</code></td>
- *         <td style="vertical-align: top;">The cursor is at the end;
- *         transliteration is complete.</td>
- *     </tr>
- * </table>
- *
- * <p>The order of rules is significant. If multiple rules may match
- * at some point, the first matching rule is applied.
- *
- * <p>Forward and reverse rules may have an empty output string.
- * Otherwise, an empty left or right hand side of any statement is a
- * syntax error.
- *
- * <p>Single quotes are used to quote any character other than a
- * digit or letter. To specify a single quote itself, inside or
- * outside of quotes, use two single quotes in a row. For example,
- * the rule &quot;<code>'&gt;'&gt;o''clock</code>&quot; changes the
- * string &quot;<code>&gt;</code>&quot; to the string &quot;<code>o'clock</code>&quot;.
- *
- * <p><b>Notes</b>
- *
- * <p>While a Transliterator is being built from rules, it checks that
- * the rules are added in proper order. For example, if the rule
- * &quot;a&gt;x&quot; is followed by the rule &quot;ab&gt;y&quot;,
- * then the second rule will throw an exception. The reason is that
- * the second rule can never be triggered, since the first rule
- * always matches anything it matches. In other words, the first
- * rule <em>masks</em> the second rule.

-/**
- * <code>TimeZoneNames</code> is an abstract class representing the time zone display name data model defined
- * by <a href="http://www.unicode.org/reports/tr35/">UTS#35 Unicode Locale Data Markup Language (LDML)</a>.
- * The model defines meta zone, which is used for storing a set of display names. A meta zone can be shared
- * by multiple time zones. Also a time zone may have multiple meta zone historic mappings.
- * <p>
- * For example, people in the United States refer the zone used by the east part of North America as "Eastern Time".
- * The tz database contains multiple time zones "America/New_York", "America/Detroit", "America/Montreal" and some
- * others that belong to "Eastern Time". However, assigning different display names to these time zones does not make
- * much sense for most of people.
- * <p>
- * In <a href="http://cldr.unicode.org/">CLDR</a> (which uses LDML for representing locale data), the display name
- * "Eastern Time" is stored as long generic display name of a meta zone identified by the ID "America_Eastern".
- * Then, there is another table maintaining the historic mapping to meta zones for each time zone. The time zones in
- * the above example ("America/New_York", "America/Detroit"...) are mapped to the meta zone "America_Eastern".
- * <p>
- * Sometimes, a time zone is mapped to a different time zone in the past. For example, "America/Indiana/Knox"
- * had been moving "Eastern Time" and "Central Time" back and forth. Therefore, it is necessary that time zone
- * to meta zones mapping data are stored by date range.
- *
- * <p><b>Note:</b>
- * The methods in this class assume that time zone IDs are already canonicalized. For example, you may not get proper
- * result returned by a method with time zone ID "America/Indiana/Indianapolis", because it's not a canonical time zone
- * ID (the canonical time zone ID for the time zone is "America/Indianapolis". See
- * {@link TimeZone#getCanonicalID(const UnicodeString& id, UnicodeString& canonicalID, UErrorCode& status)} about ICU
- * canonical time zone IDs.
- *
- * <p>
- * In CLDR, most of time zone display names except location names are provided through meta zones. But a time zone may
- * have a specific name that is not shared with other time zones.
- *
- * For example, time zone "Europe/London" has English long name for standard time "Greenwich Mean Time", which is also
- * shared with other time zones. However, the long name for daylight saving time is "British Summer Time", which is only
- * used for "Europe/London".
- *
- * <p>
- * {@link #getTimeZoneDisplayName} is designed for accessing a name only used by a single time zone.
- * But is not necessarily mean that a subclass implementation use the same model with CLDR. A subclass implementation
- * may provide time zone names only through {@link #getTimeZoneDisplayName}, or only through {@link #getMetaZoneDisplayName},
- * or both.
- *
- * <p>
- * The default <code>TimeZoneNames</code> implementation returned by {@link #createInstance}
- * uses the locale data imported from CLDR. In CLDR, set of meta zone IDs and mappings between zone IDs and meta zone
- * IDs are shared by all locales. Therefore, the behavior of {@link #getAvailableMetaZoneIDs},
- * {@link #getMetaZoneID}, and {@link #getReferenceZoneID} won't be changed no matter
- * what locale is used for getting an instance of <code>TimeZoneNames</code>.

- * \brief C API: Bidi algorithm
- *
- * <h2>Bidi algorithm for ICU</h2>
- *
- * This is an implementation of the Unicode Bidirectional Algorithm.
- * The algorithm is defined in the
- * <a href="http://www.unicode.org/unicode/reports/tr9/">Unicode Standard Annex #9</a>.<p>
- *
- * Note: Libraries that perform a bidirectional algorithm and
- * reorder strings accordingly are sometimes called "Storage Layout Engines".
- * ICU's Bidi and shaping (u_shapeArabic()) APIs can be used at the core of such
- * "Storage Layout Engines".
- *
- * <h3>General remarks about the API:</h3>
- *
- * In functions with an error code parameter,
- * the <code>pErrorCode</code> pointer must be valid
- * and the value that it points to must not indicate a failure before
- * the function call. Otherwise, the function returns immediately.
- * After the function call, the value indicates success or failure.<p>
- *
- * The &quot;limit&quot; of a sequence of characters is the position just after their
- * last character, i.e., one more than that position.<p>
- *
- * Some of the API functions provide access to &quot;runs&quot;.
- * Such a &quot;run&quot; is defined as a sequence of characters
- * that are at the same embedding level
- * after performing the Bidi algorithm.<p>

- * <h4> Sample code for the ICU Bidi API </h4>
- *
- * <h5>Rendering a paragraph with the ICU Bidi API</h5>
- *
- * This is (hypothetical) sample code that illustrates
- * how the ICU Bidi API could be used to render a paragraph of text.
- * Rendering code depends highly on the graphics system,
- * therefore this sample code must make a lot of assumptions,
- * which may or may not match any existing graphics system's properties.
- *
- * <p>The basic assumptions are:</p>
- * <ul>
- * <li>Rendering is done from left to right on a horizontal line.</li>
- * <li>A run of single-style, unidirectional text can be rendered at once.</li>
- * <li>Such a run of text is passed to the graphics system with
- *     characters (code units) in logical order.</li>
- * <li>The line-breaking algorithm is very complicated
- *     and Locale-dependent -
- *     and therefore its implementation omitted from this sample code.</li>
- * </ul>

- * UBiDiLevel is the type of the level values in this

- * by its bit&nbsp;0 (even/odd value).<p>
- *
- * It can also hold non-level values for the
- * <code>paraLevel</code> and <code>embeddingLevels</code>
- * arguments of <code>ubidi_setPara()</code>; there:

- * <li>bit&nbsp;7 of an <code>embeddingLevels[]</code>
- * value indicates whether the using application is
- * specifying the level of a character to <i>override</i> whatever the
- * Bidi implementation would resolve it to.</li>
- * <li><code>paraLevel</code> can be set to the
- * pseudo-level values <code>UBIDI_DEFAULT_LTR</code>
- * and <code>UBIDI_DEFAULT_RTL</code>.</li>
- * </ul>
- *
- * @see ubidi_setPara
- *
- * <p>The related constants are not real, valid level values.
- * <code>UBIDI_DEFAULT_XXX</code> can be used to specify
- * a default for the paragraph level for
- * when the <code>ubidi_setPara()</code> function
- * shall determine it but there is no
- * strongly typed character in the input.<p>
- *
- * Note that the value for <code>UBIDI_DEFAULT_LTR</code> is even
- * and the one for <code>UBIDI_DEFAULT_RTL</code> is odd,
- * just like with normal LTR and RTL level values -
- * these special values are designed that way. Also, the implementation
- * assumes that UBIDI_MAX_EXPLICIT_LEVEL is odd.
- *
- * Note: The numeric values of the related constants will not change:
- * They are tied to the use of 7-bit byte values (plus the override bit)
- * and of the UBiDiLevel=uint8_t data type in this API.

- *
- * <p>Some legacy systems store text in visual order, and for operations

- *
- * <p>In other cases, it may be desirable to emulate some variant of the
- * Logical to Visual algorithm (e.g. one used in MS Windows), or perform a
- * Logical to Logical transformation.</p>
- *
- * <ul>
- * <li>When the reordering mode is set to <code>#UBIDI_REORDER_DEFAULT</code>,
- * the standard Bidi Logical to Visual algorithm is applied.</li>
- *
- * <li>When the reordering mode is set to
- * <code>#UBIDI_REORDER_NUMBERS_SPECIAL</code>,
- * the algorithm used to perform Bidi transformations when calling
- * <code>ubidi_setPara</code> should approximate the algorithm used in
- * Microsoft Windows XP rather than strictly conform to the Unicode Bidi
- * algorithm.
- * <br>
- * The differences between the basic algorithm and the algorithm addressed
- * by this option are as follows:
- * <ul>
- *   <li>Within text at an even embedding level, the sequence "123AB"
- *   (where AB represent R or AL letters) is transformed to "123BA" by the
- *   Unicode algorithm and to "BA123" by the Windows algorithm.</li>
- *   <li>Arabic-Indic numbers (AN) are handled by the Windows algorithm just
- *   like regular numbers (EN).</li>
- * </ul></li>
- *
- * <li>When the reordering mode is set to
- * <code>#UBIDI_REORDER_GROUP_NUMBERS_WITH_R</code>,
- * numbers located between LTR text and RTL text are associated with the RTL
- * text. For instance, an LTR paragraph with content "abc 123 DEF" (where
- * upper case letters represent RTL characters) will be transformed to
- * "abc FED 123" (and not "abc 123 FED"), "DEF 123 abc" will be transformed
- * to "123 FED abc" and "123 FED abc" will be transformed to "DEF 123 abc".
- * This makes the algorithm reversible and makes it useful when round trip
- * (from visual to logical and back to visual) must be achieved without
- * adding LRM characters. However, this is a variation from the standard
- * Unicode Bidi algorithm.<br>
- * The source text should not contain Bidi control characters other than LRM
- * or RLM.</li>
- *
- * <li>When the reordering mode is set to
- * <code>#UBIDI_REORDER_RUNS_ONLY</code>,
- * a "Logical to Logical" transformation must be performed:
- * <ul>
- * <li>If the default text level of the source text (argument <code>paraLevel</code>
- * in <code>ubidi_setPara</code>) is even, the source text will be handled as
- * LTR logical text and will be transformed to the RTL logical text which has
- * the same LTR visual display.</li>
- * <li>If the default level of the source text is odd, the source text
- * will be handled as RTL logical text and will be transformed to the
- * LTR logical text which has the same LTR visual display.</li>
- * </ul>
- * This mode may be needed when logical text which is basically Arabic or
- * Hebrew, with possible included numbers or phrases in English, has to be
- * displayed as if it had an even embedding level (this can happen if the
- * displaying application treats all text as if it was basically LTR).
- * <br>
- * This mode may also be needed in the reverse case, when logical text which is
- * basically English, with possible included phrases in Arabic or Hebrew, has to
- * be displayed as if it had an odd embedding level.
- * <br>
- * Both cases could be handled by adding LRE or RLE at the head of the text,
- * if the display subsystem supports these formatting controls. If it does not,
- * the problem may be handled by transforming the source text in this mode
- * before displaying it, so that it will be displayed properly.<br>
- * The source text should not contain Bidi control characters other than LRM
- * or RLM.</li>
- *
- * <li>When the reordering mode is set to
- * <code>#UBIDI_REORDER_INVERSE_NUMBERS_AS_L</code>, an "inverse Bidi" algorithm
- * is applied.
- * Runs of text with numeric characters will be treated like LTR letters and
- * may need to be surrounded with LRM characters when they are written in
- * reordered sequence (the option <code>#UBIDI_INSERT_LRM_FOR_NUMERIC</code> can
- * be used with function <code>ubidi_writeReordered</code> to this end. This
- * mode is equivalent to calling <code>ubidi_setInverse()</code> with
- * argument <code>isInverse</code> set to <code>TRUE</code>.</li>
- *
- * <li>When the reordering mode is set to
- * <code>#UBIDI_REORDER_INVERSE_LIKE_DIRECT</code>, the "direct" Logical to Visual
- * Bidi algorithm is used as an approximation of an "inverse Bidi" algorithm.
- * This mode is similar to mode <code>#UBIDI_REORDER_INVERSE_NUMBERS_AS_L</code>
- * but is closer to the regular Bidi algorithm.
- * <br>
- * For example, an LTR paragraph with the content "FED 123 456 CBA" (where
- * upper case represents RTL characters) will be transformed to
- * "ABC 456 123 DEF", as opposed to "DEF 123 456 ABC"
- * with mode <code>UBIDI_REORDER_INVERSE_NUMBERS_AS_L</code>.<br>
- * When used in conjunction with option
- * <code>#UBIDI_OPTION_INSERT_MARKS</code>, this mode generally
- * adds Bidi marks to the output significantly more sparingly than mode
- * <code>#UBIDI_REORDER_INVERSE_NUMBERS_AS_L</code> with option
- * <code>#UBIDI_INSERT_LRM_FOR_NUMERIC</code> in calls to
- * <code>ubidi_writeReordered</code>.</li>
- *
- * <li>When the reordering mode is set to
- * <code>#UBIDI_REORDER_INVERSE_FOR_NUMBERS_SPECIAL</code>, the Logical to Visual
- * Bidi algorithm used in Windows XP is used as an approximation of an "inverse Bidi" algorithm.
- * <br>
- * For example, an LTR paragraph with the content "abc FED123" (where
- * upper case represents RTL characters) will be transformed to "abc 123DEF."</li>
- * </ul>
- *
- * <p>In all the reordering modes specifying an "inverse Bidi" algorithm
- * (i.e. those with a name starting with <code>UBIDI_REORDER_INVERSE</code>),
- * output runs should be retrieved using
- * <code>ubidi_getVisualRun()</code>, and the output text with
- * <code>ubidi_writeReordered()</code>. The caller should keep in mind that in
- * "inverse Bidi" modes the input is actually visually ordered text and
- * reordered output returned by <code>ubidi_getVisualRun()</code> or

- * of logically ordered output.<br>
- * For all the "inverse Bidi" modes, the source text should not contain

- *
- * <p>Note that option <code>#UBIDI_OUTPUT_REVERSE</code> of

- * ubidi_setPara() computes the left-right directionality for a given piece

- * of text (the "main text") should be considered in context, because text
- * appearing before ("prologue") and/or after ("epilogue") the main text
- * may affect the result of this computation.<p>
- *
- * This function specifies the prologue and/or the epilogue for the next
- * call to ubidi_setPara(). The characters specified as prologue and
- * epilogue should not be modified by the calling program until the call
- * to ubidi_setPara() has returned. If successive calls to ubidi_setPara()
- * all need specification of a context, ubidi_setContext() must be called
- * before each call to ubidi_setPara(). In other words, a context is not
- * "remembered" after the following successful call to ubidi_setPara().<p>
- *
- * If a call to ubidi_setPara() specifies UBIDI_DEFAULT_LTR or
- * UBIDI_DEFAULT_RTL as paraLevel and is preceded by a call to
- * ubidi_setContext() which specifies a prologue, the paragraph level will
- * be computed taking in consideration the text in the prologue.<p>
- *
- * When ubidi_setPara() is called without a previous call to
- * ubidi_setContext, the main text is handled as if preceded and followed
- * by strong directional characters at the current paragraph level.
- * Calling ubidi_setContext() with specification of a prologue will change
- * this behavior by handling the main text as if preceded by the last
- * strong character appearing in the prologue, if any.
- * Calling ubidi_setContext() with specification of an epilogue will change
- * the behavior of ubidi_setPara() by handling the main text as if followed
- * by the first strong character or digit appearing in the epilogue, if any.<p>
- *
- * Note 1: if <code>ubidi_setContext</code> is called repeatedly without
- *         calling <code>ubidi_setPara</code>, the earlier calls have no effect,
- *         only the last call will be remembered for the next call to
- *         <code>ubidi_setPara</code>.<p>
- *
- * Note 2: calling <code>ubidi_setContext(pBiDi, NULL, 0, NULL, 0, &errorCode)</code>
- *         cancels any previous setting of non-empty prologue or epilogue.
- *         The next call to <code>ubidi_setPara()</code> will process no
- *         prologue or epilogue.<p>
- *
- * Note 3: users must be aware that even after setting the context
- *         before a call to ubidi_setPara() to perform e.g. a logical to visual
- *         transformation, the resulting string may not be identical to what it
- *         would have been if all the text, including prologue and epilogue, had
- *         been processed together.<br>

- * &nbsp;&nbsp;prologue = "<code>abc DE</code>"<br>
- * &nbsp;&nbsp;epilogue = none<br>
- * &nbsp;&nbsp;main text = "<code>FGH xyz</code>"<br>

-/**
- * Perform the Unicode Bidi algorithm. It is defined in the
- * <a href="http://www.unicode.org/unicode/reports/tr9/">Unicode Standard Annex #9</a>,
- * version 13,
- * also described in The Unicode Standard, Version 4.0 .<p>
- *
- * This function takes a piece of plain text containing one or more paragraphs,
- * with or without externally specified embedding levels from <i>styled</i>
- * text and computes the left-right-directionality of each character.<p>
- *
- * If the entire text is all of the same directionality, then
- * the function may not perform all the steps described by the algorithm,
- * i.e., some levels may not be the same as if all steps were performed.
- * This is not relevant for unidirectional text.<br>
- * For example, in pure LTR text with numbers the numbers would get
- * a resolved level of 2 higher than the surrounding text according to
- * the algorithm. This implementation may set all resolved levels to
- * the same value in such a case.<p>
- *
- * The text can be composed of multiple paragraphs. Occurrence of a block
- * separator in the text terminates a paragraph, and whatever comes next starts
- * a new paragraph. The exception to this rule is when a Carriage Return (CR)
- * is followed by a Line Feed (LF). Both CR and LF are block separators, but
- * in that case, the pair of characters is considered as terminating the
- * preceding paragraph, and a new paragraph will be started by a character
- * coming after the LF.
- *
- * @param pBiDi A <code>UBiDi</code> object allocated with <code>ubidi_open()</code>
- *        which will be set to contain the reordering information,
- *        especially the resolved levels for all the characters in <code>text</code>.
- *
- * @param text is a pointer to the text that the Bidi algorithm will be performed on.
- *        This pointer is stored in the UBiDi object and can be retrieved
- *        with <code>ubidi_getText()</code>.<br>
- *        <strong>Note:</strong> the text must be (at least) <code>length</code> long.
- *
- * @param length is the length of the text; if <code>length==-1</code> then
- *        the text must be zero-terminated.
- *
- * @param paraLevel specifies the default level for the text;
- *        it is typically 0 (LTR) or 1 (RTL).
- *        If the function shall determine the paragraph level from the text,
- *        then <code>paraLevel</code> can be set to
- *        either <code>#UBIDI_DEFAULT_LTR</code>
- *        or <code>#UBIDI_DEFAULT_RTL</code>; if the text contains multiple
- *        paragraphs, the paragraph level shall be determined separately for
- *        each paragraph; if a paragraph does not include any strongly typed
- *        character, then the desired default is used (0 for LTR or 1 for RTL).
- *        Any other value between 0 and <code>#UBIDI_MAX_EXPLICIT_LEVEL</code>
- *        is also valid, with odd levels indicating RTL.
- *
- * @param embeddingLevels (in) may be used to preset the embedding and override levels,
- *        ignoring characters like LRE and PDF in the text.
- *        A level overrides the directional property of its corresponding
- *        (same index) character if the level has the
- *        <code>#UBIDI_LEVEL_OVERRIDE</code> bit set.<br><br>
- *        Aside from that bit, it must be
- *        <code>paraLevel<=embeddingLevels[]<=UBIDI_MAX_EXPLICIT_LEVEL</code>,
- *        except that level 0 is always allowed.
- *        Level 0 for a paragraph separator prevents reordering of paragraphs;
- *        this only works reliably if <code>#UBIDI_LEVEL_OVERRIDE</code>
- *        is also set for paragraph separators.
- *        Level 0 for other characters is treated as a wildcard
- *        and is lifted up to the resolved level of the surrounding paragraph.<br><br>
- *        <strong>Caution: </strong>A copy of this pointer, not of the levels,
- *        will be stored in the <code>UBiDi</code> object;
- *        the <code>embeddingLevels</code> array must not be
- *        deallocated before the <code>UBiDi</code> structure is destroyed or reused,
- *        and the <code>embeddingLevels</code>
- *        should not be modified to avoid unexpected results on subsequent Bidi operations.
- *        However, the <code>ubidi_setPara()</code> and
- *        <code>ubidi_setLine()</code> functions may modify some or all of the levels.<br><br>
- *        After the <code>UBiDi</code> object is reused or destroyed, the caller
- *        must take care of the deallocation of the <code>embeddingLevels</code> array.<br><br>
- *        <strong>Note:</strong> the <code>embeddingLevels</code> array must be

- * `UBiDiOrder` indicates the order of text.
- *
- * This bidi transformation engine supports all possible combinations (4 in
- * total) of input and output text order:
- *
- *   - <logical input, visual output>: unless the output direction is RTL, this
- *     corresponds to a normal operation of the Bidi algorithm as described in the
- *     Unicode Technical Report and implemented by `UBiDi` when the
- *     reordering mode is set to `UBIDI_REORDER_DEFAULT`. Visual RTL
- *     mode is not supported by `UBiDi` and is accomplished through
- *     reversing a visual LTR string,
- *
- *   - <visual input, logical output>: unless the input direction is RTL, this
- *     corresponds to an "inverse bidi algorithm" in `UBiDi` with the
- *     reordering mode set to `UBIDI_REORDER_INVERSE_LIKE_DIRECT`.
- *     Visual RTL mode is not not supported by `UBiDi` and is
- *     accomplished through reversing a visual LTR string,
- *
- *   - <logical input, logical output>: if the input and output base directions
- *     mismatch, this corresponds to the `UBiDi` implementation with the
- *     reordering mode set to `UBIDI_REORDER_RUNS_ONLY`; and if the
- *     input and output base directions are identical, the transformation engine
- *     will only handle character mirroring and Arabic shaping operations without
- *     reordering,
- *
- *   - <visual input, visual output>: this reordering mode is not supported by
- *     the `UBiDi` engine; it implies character mirroring, Arabic
- *     shaping, and - if the input/output base directions mismatch -  string
- *     reverse operations.

-/**
- * Performs transformation of text from the bidi layout defined by the input
- * ordering scheme to the bidi layout defined by the output ordering scheme,
- * and applies character mirroring and Arabic shaping operations.<p>
- * In terms of <code>UBiDi</code>, such a transformation implies:
- * <ul>
- * <li>calling <code>ubidi_setReorderingMode</code> as needed (when the
- * reordering mode is other than normal),</li>
- * <li>calling <code>ubidi_setInverse</code> as needed (when text should be
- * transformed from a visual to a logical form),</li>
- * <li>resolving embedding levels of each character in the input text by
- * calling <code>ubidi_setPara</code>,</li>
- * <li>reordering the characters based on the computed embedding levels, also
- * performing character mirroring as needed, and streaming the result to the
- * output, by calling <code>ubidi_writeReordered</code>,</li>
- * <li>performing Arabic digit and letter shaping on the output text by calling
- * <code>u_shapeArabic</code>.</li>
- * </ul>
- * An "ordering scheme" encompasses the base direction and the order of text,
- * and these characteristics must be defined by the caller for both input and
- * output explicitly .<p>
- * There are 36 possible combinations of <input, output> ordering schemes,
- * which are partially supported by <code>UBiDi</code> already. Examples of the
- * currently supported combinations:
- * <ul>
- * <li><Logical LTR, Visual LTR>: this is equivalent to calling
- * <code>ubidi_setPara</code> with <code>paraLevel == UBIDI_LTR</code>,</li>
- * <li><Logical RTL, Visual LTR>: this is equivalent to calling
- * <code>ubidi_setPara</code> with <code>paraLevel == UBIDI_RTL</code>,</li>
- * <li><Logical Default ("Auto") LTR, Visual LTR>: this is equivalent to
- * calling <code>ubidi_setPara</code> with
- * <code>paraLevel == UBIDI_DEFAULT_LTR</code>,</li>
- * <li><Logical Default ("Auto") RTL, Visual LTR>: this is equivalent to
- * calling <code>ubidi_setPara</code> with
- * <code>paraLevel == UBIDI_DEFAULT_RTL</code>,</li>
- * <li><Visual LTR, Logical LTR>: this is equivalent to
- * calling <code>ubidi_setInverse(UBiDi*, TRUE)</code> and then
- * <code>ubidi_setPara</code> with <code>paraLevel == UBIDI_LTR</code>,</li>
- * <li><Visual LTR, Logical RTL>: this is equivalent to
- * calling <code>ubidi_setInverse(UBiDi*, TRUE)</code> and then
- * <code>ubidi_setPara</code> with <code>paraLevel == UBIDI_RTL</code>.</li>
- * </ul>
- * All combinations that involve the Visual RTL scheme are unsupported by
- * <code>UBiDi</code>, for instance:
- * <ul>
- * <li><Logical LTR, Visual RTL>,</li>
- * <li><Visual RTL, Logical RTL>.</li>

- *        <code>paraLevel</code> parameter.
- * @param inOrder An order of the input, which can be one of the

- * \brief C API: BreakIterator
- *
- * <h2> BreakIterator C API </h2>
- *
- * The BreakIterator C API defines  methods for finding the location
- * of boundaries in text. Pointer to a UBreakIterator maintain a
- * current position and scan over text returning the index of characters
- * where boundaries occur.
- * <p>
- * Line boundary analysis determines where a text string can be broken
- * when line-wrapping. The mechanism correctly handles punctuation and
- * hyphenated words.
- * <p>
- * Note: The locale keyword "lb" can be used to modify line break
- * behavior according to the CSS level 3 line-break options, see
- * <http://dev.w3.org/csswg/css-text/#line-breaking>. For example:
- * "ja@lb=strict", "zh@lb=loose".
- * <p>
- * Sentence boundary analysis allows selection with correct
- * interpretation of periods within numbers and abbreviations, and
- * trailing punctuation marks such as quotation marks and parentheses.
- * <p>
- * Note: The locale keyword "ss" can be used to enable use of
- * segmentation suppression data (preventing breaks in English after
- * abbreviations such as "Mr." or "Est.", for example), as follows:
- * "en@ss=standard".
- * <p>
- * Word boundary analysis is used by search and replace functions, as
- * well as within text editing applications that allow the user to
- * select words with a double click. Word selection provides correct
- * interpretation of punctuation marks within and following
- * words. Characters that are not part of a word, such as symbols or
- * punctuation marks, have word-breaks on both sides.
- * <p>
- * Character boundary analysis identifies the boundaries of
- * "Extended Grapheme Clusters", which are groupings of codepoints
- * that should be treated as character-like units for many text operations.
- * Please see Unicode Standard Annex #29, Unicode Text Segmentation,
- * http://www.unicode.org/reports/tr29/ for additional information
- * on grapheme clusters and guidelines on their use.
- * <p>
- * Title boundary analysis locates all positions,
- * typically starts of words, that should be set to Title Case
- * when title casing the text.
- * <p>
- * The text boundary positions are found according to the rules
- * described in Unicode Standard Annex #29, Text Boundaries, and
- * Unicode Standard Annex #14, Line Breaking Properties.  These
- * are available at http://www.unicode.org/reports/tr14/ and
- * http://www.unicode.org/reports/tr29/.
- * <p>
- * In addition to the plain C API defined in this header file, an
- * object oriented C++ API with equivalent functionality is defined in the
- * file brkiter.h.
- * <p>
- * Code snippets illustrating the use of the Break Iterator APIs
- * are available in the ICU User Guide,
- * http://icu-project.org/userguide/boundaryAnalysis.html
- * and in the sample program icu/source/samples/break/break.cpp

- * UCalendar C API is used  for converting between a <code>UDate</code> object
- * and a set of integer fields such as <code>UCAL_YEAR</code>, <code>UCAL_MONTH</code>,
- * <code>UCAL_DAY</code>, <code>UCAL_HOUR</code>, and so on.
- * (A <code>UDate</code> object represents a specific instant in
- * time with millisecond precision. See UDate
- * for information about the <code>UDate</code> .)
- *
- * <p>
- * Types of <code>UCalendar</code> interpret a <code>UDate</code>
- * according to the rules of a specific calendar system. The U_STABLE
- * provides the enum UCalendarType with UCAL_TRADITIONAL and
- * UCAL_GREGORIAN.
- * <p>
- * Like other locale-sensitive C API, calendar API  provides a
- * function, <code>ucal_open()</code>, which returns a pointer to
- * <code>UCalendar</code> whose time fields have been initialized
- * with the current date and time. We need to specify the type of
- * calendar to be opened and the  timezoneId.
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * UCalendar *caldef;
- * UChar *tzId;
- * UErrorCode status;
- * tzId=(UChar*)malloc(sizeof(UChar) * (strlen("PST") +1) );
- * u_uastrcpy(tzId, "PST");
- * caldef=ucal_open(tzID, u_strlen(tzID), NULL, UCAL_TRADITIONAL, &status);
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * <p>
- * A <code>UCalendar</code> object can produce all the time field values
- * needed to implement the date-time formatting for a particular language
- * and calendar style (for example, Japanese-Gregorian, Japanese-Traditional).
- *
- * <p>
- * When computing a <code>UDate</code> from time fields, two special circumstances
- * may arise: there may be insufficient information to compute the
- * <code>UDate</code> (such as only year and month but no day in the month),
- * or there may be inconsistent information (such as "Tuesday, July 15, 1996"
- * -- July 15, 1996 is actually a Monday).
- *
- * <p>
- * <strong>Insufficient information.</strong> The calendar will use default
- * information to specify the missing fields. This may vary by calendar; for
- * the Gregorian calendar, the default for a field is the same as that of the
- * start of the epoch: i.e., UCAL_YEAR = 1970, UCAL_MONTH = JANUARY, UCAL_DATE = 1, etc.
- *
- * <p>
- * <strong>Inconsistent information.</strong> If fields conflict, the calendar
- * will give preference to fields set more recently. For example, when
- * determining the day, the calendar will look for one of the following
- * combinations of fields.  The most recent combination, as determined by the
- * most recently set single field, will be used.
- *
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * UCAL_MONTH + UCAL_DAY_OF_MONTH
- * UCAL_MONTH + UCAL_WEEK_OF_MONTH + UCAL_DAY_OF_WEEK
- * UCAL_MONTH + UCAL_DAY_OF_WEEK_IN_MONTH + UCAL_DAY_OF_WEEK
- * UCAL_DAY_OF_YEAR
- * UCAL_DAY_OF_WEEK + UCAL_WEEK_OF_YEAR
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * For the time of day:
- *
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- * UCAL_HOUR_OF_DAY
- * UCAL_AM_PM + UCAL_HOUR
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * <p>
- * <strong>Note:</strong> for some non-Gregorian calendars, different
- * fields may be necessary for complete disambiguation. For example, a full
- * specification of the historical Arabic astronomical calendar requires year,
- * month, day-of-month <em>and</em> day-of-week in some cases.
- *
- * <p>
- * <strong>Note:</strong> There are certain possible ambiguities in
- * interpretation of certain singular times, which are resolved in the
- * following ways:
- * <ol>
- *     <li> 24:00:00 "belongs" to the following day. That is,
- *          23:59 on Dec 31, 1969 &lt; 24:00 on Jan 1, 1970 &lt; 24:01:00 on Jan 1, 1970
- *
- *     <li> Although historically not precise, midnight also belongs to "am",
- *          and noon belongs to "pm", so on the same day,
- *          12:00 am (midnight) &lt; 12:01 am, and 12:00 pm (noon) &lt; 12:01 pm
- * </ol>
- *
- * <p>
- * The date or time format strings are not part of the definition of a
- * calendar, as those must be modifiable or overridable by the user at
- * runtime. Use {@link icu::DateFormat}
- * to format dates.
- *
- * <p>
- * <code>Calendar</code> provides an API for field "rolling", where fields
- * can be incremented or decremented, but wrap around. For example, rolling the
- * month up in the date <code>December 12, <b>1996</b></code> results in
- * <code>January 12, <b>1996</b></code>.
- *
- * <p>
- * <code>Calendar</code> also provides a date arithmetic function for
- * adding the specified (signed) amount of time to a particular time field.
- * For example, subtracting 5 days from the date <code>September 12, 1996</code>
- * results in <code>September 7, 1996</code>.
- *
- * <p>
- * The Japanese calendar uses a combination of era name and year number.
- * When an emperor of Japan abdicates and a new emperor ascends the throne,
- * a new era is declared and year number is reset to 1. Even if the date of
- * abdication is scheduled ahead of time, the new era name might not be
- * announced until just before the date. In such case, ICU4C may include
- * a start date of future era without actual era name, but not enabled
- * by default. ICU4C users who want to test the behavior of the future era
- * can enable the tentative era by:
- * <ul>
- * <li>Environment variable <code>ICU_ENABLE_TENTATIVE_ERA=true</code>.</li>
- * </ul>

-/**
- * \file
- * \brief C API: Message Catalog Wrappers
- *
- * This C API provides look-alike functions that deliberately resemble
- * the POSIX catopen, catclose, and catgets functions.  The underlying
- * implementation is in terms of ICU resource bundles, rather than
- * POSIX message catalogs.
- *
- * The ICU resource bundles obey standard ICU inheritance policies.
- * To facilitate this, sets and messages are flattened into one tier.
- * This is done by creating resource bundle keys of the form
- * &lt;set_num&gt;%&lt;msg_num&gt; where set_num is the set number and msg_num is
- * the message number, formatted as decimal strings.
- *
- * Example:  Consider a message catalog containing two sets:
- *
- * Set 1: Message 4  = "Good morning."
- *        Message 5  = "Good afternoon."
- *        Message 7  = "Good evening."
- *        Message 8  = "Good night."
- * Set 4: Message 14 = "Please "
- *        Message 19 = "Thank you."
- *        Message 20 = "Sincerely,"
- *
- * The ICU resource bundle source file would, assuming it is named
- * "greet.txt", would look like this:
- *
- * greet
- * {
- *     1%4  { "Good morning." }
- *     1%5  { "Good afternoon." }
- *     1%7  { "Good evening." }
- *     1%8  { "Good night." }
- * 
- *     4%14 { "Please " }
- *     4%19 { "Thank you." }
- *     4%20 { "Sincerely," }
- * }
- *
- * The catgets function is commonly used in combination with functions
- * like printf and strftime.  ICU components like message format can
- * be used instead, although they use a different format syntax.
- * There is an ICU package, icuio, that provides some of
- * the POSIX-style formatting API.

- * \file
- * \brief C API: Unicode Properties
- *
- * This C API provides low-level access to the Unicode Character Database.
- * In addition to raw property values, some convenience functions calculate
- * derived properties, for example for Java-style programming.
- *
- * Unicode assigns each code point (not just assigned character) values for
- * many properties.
- * Most of them are simple boolean flags, or constants from a small enumerated list.
- * For some properties, values are strings or other relatively more complex types.
- *
- * For more information see
- * "About the Unicode Character Database" (http://www.unicode.org/ucd/)
- * and the ICU User Guide chapter on Properties (http://icu-project.org/userguide/properties.html).
- *
- * Many properties are accessible via generic functions that take a UProperty selector.
- * - u_hasBinaryProperty() returns a binary value (TRUE/FALSE) per property and code point.
- * - u_getIntPropertyValue() returns an integer value per property and code point.
- *   For each supported enumerated or catalog property, there is
- *   an enum type for all of the property's values, and
- *   u_getIntPropertyValue() returns the numeric values of those constants.
- * - u_getBinaryPropertySet() returns a set for each ICU-supported binary property with
- *   all code points for which the property is true.
- * - u_getIntPropertyMap() returns a map for each
- *   ICU-supported enumerated/catalog/int-valued property which
- *   maps all Unicode code points to their values for that property.
- *
- * Many functions are designed to match java.lang.Character functions.
- * See the individual function documentation,
- * and see the JDK 1.4 java.lang.Character documentation
- * at http://java.sun.com/j2se/1.4/docs/api/java/lang/Character.html
- *
- * There are also functions that provide easy migration from C/POSIX functions
- * like isblank(). Their use is generally discouraged because the C/POSIX
- * standards do not define their semantics beyond the ASCII range, which means
- * that different implementations exhibit very different behavior.
- * Instead, Unicode properties should be used directly.
- *
- * There are also only a few, broad C/POSIX character classes, and they tend
- * to be used for conflicting purposes. For example, the "isalpha()" class
- * is sometimes used to determine word boundaries, while a more sophisticated
- * approach would at least distinguish initial letters from continuation
- * characters (the latter including combining marks).
- * (In ICU, BreakIterator is the most sophisticated API for word boundaries.)
- * Another example: There is no "istitle()" class for titlecase characters.
- *
- * ICU 3.4 and later provides API access for all twelve C/POSIX character classes.
- * ICU implements them according to the Standard Recommendations in
- * Annex C: Compatibility Properties of UTS #18 Unicode Regular Expressions
- * (http://www.unicode.org/reports/tr18/#Compatibility_Properties).

- * API access for C/POSIX character classes is as follows:
- * - alpha:     u_isUAlphabetic(c) or u_hasBinaryProperty(c, UCHAR_ALPHABETIC)
- * - lower:     u_isULowercase(c) or u_hasBinaryProperty(c, UCHAR_LOWERCASE)
- * - upper:     u_isUUppercase(c) or u_hasBinaryProperty(c, UCHAR_UPPERCASE)
- * - punct:     u_ispunct(c)
- * - digit:     u_isdigit(c) or u_charType(c)==U_DECIMAL_DIGIT_NUMBER
- * - xdigit:    u_isxdigit(c) or u_hasBinaryProperty(c, UCHAR_POSIX_XDIGIT)
- * - alnum:     u_hasBinaryProperty(c, UCHAR_POSIX_ALNUM)
- * - space:     u_isUWhiteSpace(c) or u_hasBinaryProperty(c, UCHAR_WHITE_SPACE)
- * - blank:     u_isblank(c) or u_hasBinaryProperty(c, UCHAR_POSIX_BLANK)
- * - cntrl:     u_charType(c)==U_CONTROL_CHAR
- * - graph:     u_hasBinaryProperty(c, UCHAR_POSIX_GRAPH)
- * - print:     u_hasBinaryProperty(c, UCHAR_POSIX_PRINT)
- *
- * Note: Some of the u_isxyz() functions in uchar.h predate, and do not match,
- * the Standard Recommendations in UTS #18. Instead, they match Java
- * functions according to their API documentation.
- *
- * \htmlonly
- * The C/POSIX character classes are also available in UnicodeSet patterns,
- * using patterns like [:graph:] or \p{graph}.
- * \endhtmlonly
- *
- * Note: There are several ICU whitespace functions.
- * Comparison:
- * - u_isUWhiteSpace=UCHAR_WHITE_SPACE: Unicode White_Space property;
- *       most of general categories "Z" (separators) + most whitespace ISO controls
- *       (including no-break spaces, but excluding IS1..IS4)
- * - u_isWhitespace: Java isWhitespace; Z + whitespace ISO controls but excluding no-break spaces
- * - u_isJavaSpaceChar: Java isSpaceChar; just Z (including no-break spaces)
- * - u_isspace: Z + whitespace ISO controls (including no-break spaces)
- * - u_isblank: "horizontal spaces" = TAB + Zs

-    //      If the last unit matches, then matching continues with the next node.
-    //      (Values have the same encoding as final-value nodes.)
-    //    - If the length is greater than kMaxBranchLinearSubNodeLength, then
-    //      there is one unit and one "jump" delta.
-    //      If the input unit is less than the sub-node unit, then "jump" by delta to
-    //      the next sub-node which will have a length of length/2.
-    //      (The delta has its own compact encoding.)

- *
- *  Use of this function is optional.  It is OK to simply use ICU
- *  services and functions without first having initialized
- *  ICU by calling u_init().
- *
- *  u_init() will attempt to load some part of ICU's data, and is
- *  useful as a test for configuration or installation problems that
- *  leave the ICU data inaccessible.  A successful invocation of u_init()
- *  does not, however, guarantee that all ICU data is accessible.
- *
- *  Multiple calls to u_init() cause no harm, aside from the small amount
- *  of time required.
- *
- *  In old versions of ICU, u_init() was required in multi-threaded applications
- *  to ensure the thread safety of ICU.  u_init() is no longer needed for this purpose.
- *
- * @param status An ICU UErrorCode parameter. It must not be <code>NULL</code>.
- *    An Error will be returned if some required part of ICU data can not
- *    be loaded or initialized.
- *    The function returns immediately if the input error code indicates a

-/**
- * Clean up the system resources, such as allocated memory or open files,
- * used in all ICU libraries. This will free/delete all memory owned by the
- * ICU libraries, and return them to their original load state. All open ICU
- * items (collators, resource bundles, converters, etc.) must be closed before
- * calling this function, otherwise ICU may not free its allocated memory
- * (e.g. close your converters and resource bundles before calling this
- * function). Generally, this function should be called once just before
- * an application exits. For applications that dynamically load and unload
- * the ICU libraries (relatively uncommon), u_cleanup() should be called
- * just before the library unload.
- * <p>
- * u_cleanup() also clears any ICU heap functions, mutex functions or
- * trace functions that may have been set for the process.  
- * This has the effect of restoring ICU to its initial condition, before
- * any of these override functions were installed.  Refer to
- * u_setMemoryFunctions(), u_setMutexFunctions and 
- * utrace_setFunctions().  If ICU is to be reinitialized after
- * calling u_cleanup(), these runtime override functions will need to
- * be set up again if they are still required.
- * <p>
- * u_cleanup() is not thread safe.  All other threads should stop using ICU
- * before calling this function.
- * <p>
- * Any open ICU items will be left in an undefined state by u_cleanup(),
- * and any subsequent attempt to use such an item will give unpredictable
- * results.
- * <p>
- * After calling u_cleanup(), an application may continue to use ICU by
- * calling u_init().  An application must invoke u_init() first from one single
- * thread before allowing other threads call u_init().  All threads existing
- * at the time of the first thread's call to u_init() must also call
- * u_init() themselves before continuing with other ICU operations.  
- * <p>
- * The use of u_cleanup() just before an application terminates is optional,
- * but it should be called only once for performance reasons. The primary
- * benefit is to eliminate reports of memory or resource leaks originating
- * in ICU code from the results generated by heap analysis tools.

- * \brief C API: Character conversion
- *
- * <h2>Character Conversion C API</h2>
- *
- * <p>This API is used to convert codepage or character encoded data to and
- * from UTF-16. You can open a converter with {@link ucnv_open() }. With that
- * converter, you can get its properties, set options, convert your data and
- * close the converter.</p>
- *
- * <p>Since many software programs recognize different converter names for
- * different types of converters, there are other functions in this API to
- * iterate over the converter aliases. The functions {@link ucnv_getAvailableName() },
- * {@link ucnv_getAlias() } and {@link ucnv_getStandardName() } are some of the
- * more frequently used alias functions to get this information.</p>
- *
- * <p>When a converter encounters an illegal, irregular, invalid or unmappable character
- * its default behavior is to use a substitution character to replace the
- * bad byte sequence. This behavior can be changed by using {@link ucnv_setFromUCallBack() }
- * or {@link ucnv_setToUCallBack() } on the converter. The header ucnv_err.h defines
- * many other callback actions that can be used instead of a character substitution.</p>
- *
- * <p>More information about this API can be found in our
- * <a href="http://icu-project.org/userguide/conversion.html">User's
- * Guide</a>.</p>

- * number of bytes per character that would be published for a charset,
- * and may not fulfill any other purpose than the allocation of an output
- * buffer of guaranteed sufficient size for a given input length and converter.
- *
- * Examples for special cases that are taken into account:
- * - Supplementary code points may convert to more bytes than BMP code points.
- *   This function returns bytes per UChar (UTF-16 code unit), not per
- *   Unicode code point, for efficient buffer allocation.
- * - State-shifting output (SI/SO, escapes, etc.) from stateful converters.
- * - When m input UChars are converted to n output bytes, then the maximum m/n
- *   is taken into account.
- *
- * The number returned here does not take into account
- * (see UCNV_GET_MAX_BYTES_FOR_STRING):
- * - callbacks which output more than one charset character sequence per call,
- *   like escape callbacks
- * - initial and final non-character bytes that are output by some converters
- *   (automatic BOMs, initial escape sequence, final SI, etc.)
- *
- * Examples for returned values:
- * - SBCS charsets: 1
- * - Shift-JIS: 2
- * - UTF-16: 2 (2 per BMP, 4 per surrogate _pair_, BOM not counted)
- * - UTF-8: 3 (3 per BMP, 4 per surrogate _pair_)
- * - EBCDIC_STATEFUL (EBCDIC mixed SBCS/DBCS): 3 (SO + DBCS)
- * - ISO-2022: 3 (always outputs UTF-8)
- * - ISO-2022-JP: 6 (4-byte escape sequences + DBCS)

-/**
- * Convert a codepage buffer into Unicode one character at a time.
- * The input is completely consumed when the U_INDEX_OUTOFBOUNDS_ERROR is set.
- *
- * Advantage compared to ucnv_toUnicode() or ucnv_toUChars():
- * - Faster for small amounts of data, for most converters, e.g.,
- *   US-ASCII, ISO-8859-1, UTF-8/16/32, and most "normal" charsets.
- *   (For complex converters, e.g., SCSU, UTF-7 and ISO 2022 variants,
- *    it uses ucnv_toUnicode() internally.)
- * - Convenient.
- *
- * Limitations compared to ucnv_toUnicode():
- * - Always assumes flush=TRUE.
- *   This makes ucnv_getNextUChar() unsuitable for "streaming" conversion,
- *   that is, for where the input is supplied in multiple buffers,
- *   because ucnv_getNextUChar() will assume the end of the input at the end
- *   of the first buffer.
- * - Does not provide offset output.
- *
- * It is possible to "mix" ucnv_getNextUChar() and ucnv_toUnicode() because
- * ucnv_getNextUChar() uses the current state of the converter
- * (unlike ucnv_toUChars() which always resets first).
- * However, if ucnv_getNextUChar() is called after ucnv_toUnicode()
- * stopped in the middle of a character sequence (with flush=FALSE),
- * then ucnv_getNextUChar() will always use the slower ucnv_toUnicode()
- * internally until the next character boundary.
- * (This is new in ICU 2.6. In earlier releases, ucnv_getNextUChar() had to
- * start at a character boundary.)
- *
- * Instead of using ucnv_getNextUChar(), it is recommended
- * to convert using ucnv_toUnicode() or ucnv_toUChars()
- * and then iterate over the text using U16_NEXT() or a UCharIterator (uiter.h)
- * or a C++ CharacterIterator or similar.
- * This allows streaming conversion and offset output, for example.
- *
- * <p>Handling of surrogate pairs and supplementary-plane code points:<br>
- * There are two different kinds of codepages that provide mappings for surrogate characters:
- * <ul>
- *   <li>Codepages like UTF-8, UTF-32, and GB 18030 provide direct representations for Unicode
- *       code points U+10000-U+10ffff as well as for single surrogates U+d800-U+dfff.
- *       Each valid sequence will result in exactly one returned code point.
- *       If a sequence results in a single surrogate, then that will be returned
- *       by itself, even if a neighboring sequence encodes the matching surrogate.</li>
- *   <li>Codepages like SCSU and LMBCS (and UTF-16) provide direct representations only for BMP code points
- *       including surrogates. Code points in supplementary planes are represented with
- *       two sequences, each encoding a surrogate.
- *       For these codepages, matching pairs of surrogates will be combined into single
- *       code points for returning from this function.
- *       (Note that SCSU is actually a mix of these codepage types.)</li>
- * </ul></p>
- *
- * @param converter an open UConverter
- * @param source the address of a pointer to the codepage buffer, will be
- *  updated to point after the bytes consumed in the conversion call.
- * @param sourceLimit points to the end of the input buffer
- * @param err fills in error status (see ucnv_toUnicode)
- * <code>U_INDEX_OUTOFBOUNDS_ERROR</code> will be set if the input
- * is empty or does not convert to any output (e.g.: pure state-change
- * codes SI/SO, escape sequences for ISO 2022,
- * or if the callback did not output anything, ...).
- * This function will not set a <code>U_BUFFER_OVERFLOW_ERROR</code> because
- *  the "buffer" is the return code. However, there might be subsequent output
- *  stored in the converter object
- * that will be returned in following calls to this function.

-/**
- * Convert from one external charset to another using two existing UConverters.
- * Internally, two conversions - ucnv_toUnicode() and ucnv_fromUnicode() -
- * are used, "pivoting" through 16-bit Unicode.
- *
- * Important: For streaming conversion (multiple function calls for successive
- * parts of a text stream), the caller must provide a pivot buffer explicitly,
- * and must preserve the pivot buffer and associated pointers from one
- * call to another. (The buffer may be moved if its contents and the relative
- * pointer positions are preserved.)
- *
- * There is a similar function, ucnv_convert(),
- * which has the following limitations:
- * - it takes charset names, not converter objects, so that
- *   - two converters are opened for each call
- *   - only single-string conversion is possible, not streaming operation
- * - it does not provide enough information to find out,
- *   in case of failure, whether the toUnicode or
- *   the fromUnicode conversion failed
- *
- * By contrast, ucnv_convertEx()
- * - takes UConverter parameters instead of charset names
- * - fully exposes the pivot buffer for streaming conversion and complete error handling
- *
- * ucnv_convertEx() also provides further convenience:
- * - an option to reset the converters at the beginning
- *   (if reset==TRUE, see parameters;
- *    also sets *pivotTarget=*pivotSource=pivotStart)
- * - allow NUL-terminated input
- *   (only a single NUL byte, will not work for charsets with multi-byte NULs)
- *   (if sourceLimit==NULL, see parameters)
- * - terminate with a NUL on output
- *   (only a single NUL byte, not useful for charsets with multi-byte NULs),
- *   or set U_STRING_NOT_TERMINATED_WARNING if the output exactly fills
- *   the target buffer
- * - the pivot buffer can be provided internally;
- *   possible only for whole-string conversion, not streaming conversion;
- *   in this case, the caller will not be able to get details about where an
- *   error occurred
- *   (if pivotStart==NULL, see below)
- *
- * The function returns when one of the following is true:
- * - the entire source text has been converted successfully to the target buffer
- * - a target buffer overflow occurred (U_BUFFER_OVERFLOW_ERROR)
- * - a conversion error occurred
- *   (other U_FAILURE(), see description of pErrorCode)
- *
- * Limitation compared to the direct use of
- * ucnv_fromUnicode() and ucnv_toUnicode():
- * ucnv_convertEx() does not provide offset information.
- *
- * Limitation compared to ucnv_fromUChars() and ucnv_toUChars():
- * ucnv_convertEx() does not support preflighting directly.
- *
- * Sample code for converting a single string from
- * one external charset to UTF-8, ignoring the location of errors:
- *
- * \code
- * int32_t
- * myToUTF8(UConverter *cnv,
- *          const char *s, int32_t length,
- *          char *u8, int32_t capacity,

- *
- *     if(length<0) {

-/**
- * \file 
- * \brief C UConverter functions to aid the writers of callbacks
- *
- * <h2> Callback API for UConverter </h2>
- * 
- * These functions are provided here for the convenience of the callback
- * writer. If you are just looking for callback functions to use, please
- * see ucnv_err.h.  DO NOT call these functions directly when you are 
- * working with converters, unless your code has been called as a callback
- * via ucnv_setFromUCallback or ucnv_setToUCallback !!
- * 
- * A note about error codes and overflow.  Unlike other ICU functions,
- * these functions do not expect the error status to be U_ZERO_ERROR.
- * Callbacks must be much more careful about their error codes.
- * The error codes used here are in/out parameters, which should be passed
- * back in the callback's error parameter.
- * 
- * For example, if you call ucnv_cbfromUWriteBytes to write data out 
- * to the output codepage, it may return U_BUFFER_OVERFLOW_ERROR if 
- * the data did not fit in the target. But this isn't a failing error, 
- * in fact, ucnv_cbfromUWriteBytes may be called AGAIN with the error
- * status still U_BUFFER_OVERFLOW_ERROR to attempt to write further bytes,
- * which will also go into the internal overflow buffers.
- * 
- * Concerning offsets, the 'offset' parameters here are relative to the start
- * of SOURCE.  For example, Suppose the string "ABCD" was being converted 
- * from Unicode into a codepage which doesn't have a mapping for 'B'.
- * 'A' will be written out correctly, but
- * The FromU Callback will be called on an unassigned character for 'B'.
- * At this point, this is the state of the world:
- *    Target:    A [..]     [points after A]
- *    Source:  A B [C] D    [points to C - B has been consumed]
- *             0 1  2  3 
- *    codePoint = "B"       [the unassigned codepoint] 
- * 
- * Now, suppose a callback wants to write the substitution character '?' to
- * the target. It calls ucnv_cbFromUWriteBytes() to write the ?. 
- * It should pass ZERO as the offset, because the offset as far as the 
- * callback is concerned is relative to the SOURCE pointer [which points 
- * before 'C'.]  If the callback goes into the args and consumes 'C' also,
- * it would call FromUWriteBytes with an offset of 1 (and advance the source
- * pointer).

-/**
- * \file
- * \brief C UConverter predefined error callbacks
- *
- *  <h2>Error Behaviour Functions</h2>
- *  Defines some error behaviour functions called by ucnv_{from,to}Unicode
- *  These are provided as part of ICU and many are stable, but they
- *  can also be considered only as an example of what can be done with
- *  callbacks.  You may of course write your own.
- *
- *  If you want to write your own, you may also find the functions from
- *  ucnv_cb.h useful when writing your own callbacks.
- *
- *  These functions, although public, should NEVER be called directly.
- *  They should be used as parameters to the ucnv_setFromUCallback
- *  and ucnv_setToUCallback functions, to set the behaviour of a converter
- *  when it encounters ILLEGAL/UNMAPPED/INVALID sequences.
- *
- *  usage example:  'STOP' doesn't need any context, but newContext
- *    could be set to something other than 'NULL' if needed. The available
- *    contexts in this header can modify the default behavior of the callback.
- *
- *  \code
- *  UErrorCode err = U_ZERO_ERROR;
- *  UConverter *myConverter = ucnv_open("ibm-949", &err);
- *  const void *oldContext;
- *  UConverterFromUCallback oldAction;
- *
- *
- *  if (U_SUCCESS(err))
- *  {
- *      ucnv_setFromUCallBack(myConverter,
- *                       UCNV_FROM_U_CALLBACK_STOP,
- *                       NULL,
- *                       &oldAction,
- *                       &oldContext,
- *                       &status);
- *  }
- *  \endcode
- *
- *  The code above tells "myConverter" to stop when it encounters an
- *  ILLEGAL/TRUNCATED/INVALID sequences when it is used to convert from
- *  Unicode -> Codepage. The behavior from Codepage to Unicode is not changed,
- *  and ucnv_setToUCallBack would need to be called in order to change
- *  that behavior too.
- *
- *  Here is an example with a context:
- *
- *  \code
- *  UErrorCode err = U_ZERO_ERROR;
- *  UConverter *myConverter = ucnv_open("ibm-949", &err);
- *  const void *oldContext;
- *  UConverterFromUCallback oldAction;
- *
- *
- *  if (U_SUCCESS(err))

- *
- * <h2> Collator C API </h2>
- *
- * The C API for Collator performs locale-sensitive
- * string comparison. You use this service to build
- * searching and sorting routines for natural language text.
- * <p>
- * For more information about the collation service see 
- * <a href="http://userguide.icu-project.org/collation">the User Guide</a>.
- * <p>
- * Collation service provides correct sorting orders for most locales supported in ICU. 
- * If specific data for a locale is not available, the orders eventually falls back
- * to the <a href="http://www.unicode.org/reports/tr35/tr35-collation.html#Root_Collation">CLDR root sort order</a>. 
- * <p>
- * Sort ordering may be customized by providing your own set of rules. For more on
- * this subject see the <a href="http://userguide.icu-project.org/collation/customization">
- * Collation Customization</a> section of the User Guide.

-/**
- * \file
- * \brief C API: UCollationElements
- *
- * The UCollationElements API is used as an iterator to walk through each 
- * character of an international string. Use the iterator to return the
- * ordering priority of the positioned character. The ordering priority of a 
- * character, which we refer to as a key, defines how a character is collated 
- * in the given collation object.
- * For example, consider the following in Slovak and in traditional Spanish collation:
- * <pre>
- * .       "ca" -> the first key is key('c') and second key is key('a').
- * .       "cha" -> the first key is key('ch') and second key is key('a').
- * </pre>
- * And in German phonebook collation,
- * <pre>
- * .       "<ae ligature>b"-> the first key is key('a'), the second key is key('e'), and
- * .       the third key is key('b').
- * </pre>
- * <p>Example of the iterator usage: (without error checking)
- * <pre>
- * .  void CollationElementIterator_Example()
- * .  {
- * .      UChar *s;
- * .      t_int32 order, primaryOrder;
- * .      UCollationElements *c;
- * .      UCollatorOld *coll;
- * .      UErrorCode success = U_ZERO_ERROR;
- * .      s=(UChar*)malloc(sizeof(UChar) * (strlen("This is a test")+1) );
- * .      u_uastrcpy(s, "This is a test");
- * .      coll = ucol_open(NULL, &success);
- * .      c = ucol_openElements(coll, str, u_strlen(str), &status);
- * .      order = ucol_next(c, &success);
- * .      ucol_reset(c);
- * .      order = ucol_prev(c, &success);
- * .      free(s);
- * .      ucol_close(coll);
- * .      ucol_closeElements(c);
- * .  }
- * </pre>
- * <p>
- * ucol_next() returns the collation order of the next.
- * ucol_prev() returns the collation order of the previous character.
- * The Collation Element Iterator moves only in one direction between calls to
- * ucol_reset. That is, ucol_next() and ucol_prev can not be inter-used. 
- * Whenever ucol_prev is to be called after ucol_next() or vice versa, 
- * ucol_reset has to be called first to reset the status, shifting pointers to 
- * either the end or the start of the string. Hence at the next call of 
- * ucol_prev or ucol_next, the first or last collation order will be returned. 
- * If a change of direction is done without a ucol_reset, the result is 
- * undefined.
- * The result of a forward iterate (ucol_next) and reversed result of the  
- * backward iterate (ucol_prev) on the same string are equivalent, if 
- * collation orders with the value 0 are ignored.
- * Character based on the comparison level of the collator.  A collation order 
- * consists of primary order, secondary order and tertiary order.  The data 
- * type of the collation order is <strong>int32_t</strong>.

- * \file 
- * \brief C API: Charset Detection API
- *
- * This API provides a facility for detecting the
- * charset or encoding of character data in an unknown text format.
- * The input data can be from an array of bytes.
- * <p>
- * Character set detection is at best an imprecise operation.  The detection
- * process will attempt to identify the charset that best matches the characteristics
- * of the byte data, but the process is partly statistical in nature, and
- * the results can not be guaranteed to always be correct.
- * <p>
- * For best accuracy in charset detection, the input data should be primarily
- * in a single language, and a minimum of a few hundred bytes worth of plain text
- * in the language are needed.  The detection process will attempt to
- * ignore html or xml style markup that could otherwise obscure the content.
- * <p>
- * An alternative to the ICU Charset Detector is the
- * Compact Encoding Detector, https://github.com/google/compact_enc_det.
- * It often gives more accurate results, especially with short input samples.

- * \file
- * \brief C API: DateFormat
- *
- * <h2> Date Format C API</h2>
- *
- * Date Format C API  consists of functions that convert dates and
- * times from their internal representations to textual form and back again in a
- * language-independent manner. Converting from the internal representation (milliseconds
- * since midnight, January 1, 1970) to text is known as "formatting," and converting
- * from text to millis is known as "parsing."  We currently define only one concrete
- * structure UDateFormat, which can handle pretty much all normal
- * date formatting and parsing actions.
- * <P>
- * Date Format helps you to format and parse dates for any locale. Your code can
- * be completely independent of the locale conventions for months, days of the
- * week, or even the calendar format: lunar vs. solar.
- * <P>
- * To format a date for the current Locale with default time and date style,
- * use one of the static factory methods:
- * <pre>
- * \code
- *  UErrorCode status = U_ZERO_ERROR;
- *  UChar *myString;
- *  int32_t myStrlen = 0;
- *  UDateFormat* dfmt = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, NULL, -1, NULL, -1, &status);
- *  myStrlen = udat_format(dfmt, myDate, NULL, myStrlen, NULL, &status);
- *  if (status==U_BUFFER_OVERFLOW_ERROR){
- *      status=U_ZERO_ERROR;
- *      myString=(UChar*)malloc(sizeof(UChar) * (myStrlen+1) );
- *      udat_format(dfmt, myDate, myString, myStrlen+1, NULL, &status);
- *  }
- * \endcode
- * </pre>
- * If you are formatting multiple numbers, it is more efficient to get the
- * format and use it multiple times so that the system doesn't have to fetch the
- * information about the local language and country conventions multiple times.
- * <pre>
- * \code
- *  UErrorCode status = U_ZERO_ERROR;
- *  int32_t i, myStrlen = 0;
- *  UChar* myString;
- *  char buffer[1024];
- *  UDate myDateArr[] = { 0.0, 100000000.0, 2000000000.0 }; // test values
- *  UDateFormat* df = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, NULL, -1, NULL, 0, &status);
- *  for (i = 0; i < 3; i++) {
- *      myStrlen = udat_format(df, myDateArr[i], NULL, myStrlen, NULL, &status);
- *      if(status == U_BUFFER_OVERFLOW_ERROR){
- *          status = U_ZERO_ERROR;
- *          myString = (UChar*)malloc(sizeof(UChar) * (myStrlen+1) );
- *          udat_format(df, myDateArr[i], myString, myStrlen+1, NULL, &status);
- *          printf("%s\n", u_austrcpy(buffer, myString) );
- *          free(myString);
- *      }
- *  }
- * \endcode
- * </pre>
- * To get specific fields of a date, you can use UFieldPosition to
- * get specific fields.
- * <pre>
- * \code
- *  UErrorCode status = U_ZERO_ERROR;
- *  UFieldPosition pos;
- *  UChar *myString;
- *  int32_t myStrlen = 0;
- *  char buffer[1024];
- *
- *  pos.field = 1;  // Same as the DateFormat::EField enum
- *  UDateFormat* dfmt = udat_open(UDAT_DEFAULT, UDAT_DEFAULT, NULL, -1, NULL, 0, &status);
- *  myStrlen = udat_format(dfmt, myDate, NULL, myStrlen, &pos, &status);
- *  if (status==U_BUFFER_OVERFLOW_ERROR){
- *      status=U_ZERO_ERROR;
- *      myString=(UChar*)malloc(sizeof(UChar) * (myStrlen+1) );
- *      udat_format(dfmt, myDate, myString, myStrlen+1, &pos, &status);
- *  }
- *  printf("date format: %s\n", u_austrcpy(buffer, myString));
- *  buffer[pos.endIndex] = 0;   // NULL terminate the string.
- *  printf("UFieldPosition position equals %s\n", &buffer[pos.beginIndex]);
- * \endcode
- * </pre>
- * To format a date for a different Locale, specify it in the call to
- * udat_open()
- * <pre>
- * \code
- *        UDateFormat* df = udat_open(UDAT_SHORT, UDAT_SHORT, "fr_FR", NULL, -1, NULL, 0, &status);
- * \endcode
- * </pre>
- * You can use a DateFormat API udat_parse() to parse.
- * <pre>
- * \code
- *  UErrorCode status = U_ZERO_ERROR;
- *  int32_t parsepos=0;
- *  UDate myDate = udat_parse(df, myString, u_strlen(myString), &parsepos, &status);
- * \endcode
- * </pre>
- *  You can pass in different options for the arguments for date and time style
- *  to control the length of the result; from SHORT to MEDIUM to LONG to FULL.
- *  The exact result depends on the locale, but generally:
- *  see UDateFormatStyle for more details
- * <ul type=round>
- *   <li>   UDAT_SHORT is completely numeric, such as 12/13/52 or 3:30pm
- *   <li>   UDAT_MEDIUM is longer, such as Jan 12, 1952
- *   <li>   UDAT_LONG is longer, such as January 12, 1952 or 3:30:32pm
- *   <li>   UDAT_FULL is pretty completely specified, such as
- *          Tuesday, April 12, 1952 AD or 3:30:42pm PST.
- * </ul>
- * You can also set the time zone on the format if you wish.
- * <P>
- * You can also use forms of the parse and format methods with Parse Position and
- * UFieldPosition to allow you to
- * <ul type=round>
- *   <li>   Progressively parse through pieces of a string.
- *   <li>   Align any particular field, or find out where it is for selection
- *          on the screen.
- * </ul>
- * <p><strong>Date and Time Patterns:</strong></p>
- *
- * <p>Date and time formats are specified by <em>date and time pattern</em> strings.
- * Within date and time pattern strings, all unquoted ASCII letters [A-Za-z] are reserved
- * as pattern letters representing calendar fields. <code>UDateFormat</code> supports
- * the date and time formatting algorithm and pattern letters defined by
- * <a href="http://www.unicode.org/reports/tr35/tr35-dates.html#Date_Field_Symbol_Table">UTS#35
- * Unicode Locale Data Markup Language (LDML)</a> and further documented for ICU in the
- * <a href="https://sites.google.com/site/icuprojectuserguide/formatparse/datetime?pli=1#TOC-Date-Field-Symbol-Table">ICU
- * User Guide</a>.</p>

- *
- * <p>This structure may grow in the future, indicated by the

- *
- * <p>ICU data must be at least 8-aligned, and should be 16-aligned.
- * The UDataInfo struct begins 4 bytes after the start of the data item,
- * so it is 4-aligned.
- *
- * <p>The platform data property fields help determine if a data
- * file can be efficiently used on a given machine.
- * The particular fields are of importance only if the data
- * is affected by the properties - if there is integer data
- * with word sizes > 1 byte, char* text, or UChar* text.</p>
- *
- * <p>The implementation for the <code>udata_open[Choice]()</code>
- * functions may reject data based on the value in <code>isBigEndian</code>.
- * No other field is used by the <code>udata</code> API implementation.</p>
- *
- * <p>The <code>dataFormat</code> may be used to identify
- * the kind of data, e.g. a converter table.</p>
- *
- * <p>The <code>formatVersion</code> field should be used to
- * make sure that the format can be interpreted.
- * It may be a good idea to check only for the one or two highest
- * of the version elements to allow the data memory to
- * get more or somewhat rearranged contents, for as long
- * as the using code can still interpret the older contents.</p>
- *
- * <p>The <code>dataVersion</code> field is intended to be a
- * common place to store the source version of the data;
- * for data from the Unicode character database, this could
- * reflect the Unicode version.</p>

-/**
- * \file
- * \brief C API: Format a date interval.
- *
- * A UDateIntervalFormat is used to format the range between two UDate values
- * in a locale-sensitive way, using a skeleton that specifies the precision and
- * completeness of the information to show. If the range smaller than the resolution
- * specified by the skeleton, a single date format will be produced. If the range
- * is larger than the format specified by the skeleton, a locale-specific fallback
- * will be used to format the items missing from the skeleton.
- *
- * For example, if the range is 2010-03-04 07:56 - 2010-03-04 19:56 (12 hours)
- * - The skeleton jm will produce
- *   for en_US, "7:56 AM - 7:56 PM"
- *   for en_GB, "7:56 - 19:56"
- * - The skeleton MMMd will produce
- *   for en_US, "Mar 4"
- *   for en_GB, "4 Mar"
- * If the range is 2010-03-04 07:56 - 2010-03-08 16:11 (4 days, 8 hours, 15 minutes)
- * - The skeleton jm will produce
- *   for en_US, "3/4/2010 7:56 AM - 3/8/2010 4:11 PM"
- *   for en_GB, "4/3/2010 7:56 - 8/3/2010 16:11"
- * - The skeleton MMMd will produce
- *   for en_US, "Mar 4-8"
- *   for en_GB, "4-8 Mar"
- * 
- * Note:  the "-" characters in the above sample output will actually be
- * Unicode 2013, EN_DASH, in all but the last example.
- *
- * Note, in ICU 4.4 the standard skeletons for which date interval format data
- * is usually available are as follows; best results will be obtained by using
- * skeletons from this set, or those formed by combining these standard skeletons
- * (note that for these skeletons, the length of digit field such as d, y, or
- * M vs MM is irrelevant (but for non-digit fields such as MMM vs MMMM it is
- * relevant). Note that a skeleton involving h or H generally explicitly requests
- * that time style (12- or 24-hour time respectively). For a skeleton that
- * requests the locale's default time style (h or H), use 'j' instead of h or H.
- *   h, H, hm, Hm,
- *   hv, Hv, hmv, Hmv,
- *   d,
- *   M, MMM, MMMM,
- *   Md, MMMd,
- *   MEd, MMMEd,
- *   y,
- *   yM, yMMM, yMMMM,
- *   yMd, yMMMd,
- *   yMEd, yMMMEd
- *
- * Locales for which ICU 4.4 seems to have a reasonable amount of this data
- * include:
- *   af, am, ar, be, bg, bn, ca, cs, da, de (_AT), el, en (_AU,_CA,_GB,_IE,_IN...),
- *   eo, es (_AR,_CL,_CO,...,_US) et, fa, fi, fo, fr (_BE,_CH,_CA), fur, gsw, he,
- *   hr, hu, hy, is, it (_CH), ja, kk, km, ko, lt, lv, mk, ml, mt, nb, nl )_BE),
- *   nn, pl, pt (_PT), rm, ro, ru (_UA), sk, sl, so, sq, sr, sr_Latn, sv, th, to,

-/**
- * IDNA2003: This function implements the ToASCII operation as defined in the IDNA RFC.
- * This operation is done on <b>single labels</b> before sending it to something that expects
- * ASCII names. A label is an individual part of a domain name. Labels are usually
- * separated by dots; e.g. "www.example.com" is composed of 3 labels "www","example", and "com".
- *
- * IDNA2003 API Overview:
- *
- * The uidna_ API implements the IDNA protocol as defined in the IDNA RFC
- * (http://www.ietf.org/rfc/rfc3490.txt).
- * The RFC defines 2 operations: ToASCII and ToUnicode. Domain name labels
- * containing non-ASCII code points are processed by the
- * ToASCII operation before passing it to resolver libraries. Domain names
- * that are obtained from resolver libraries are processed by the
- * ToUnicode operation before displaying the domain name to the user.
- * IDNA requires that implementations process input strings with Nameprep
- * (http://www.ietf.org/rfc/rfc3491.txt),
- * which is a profile of Stringprep (http://www.ietf.org/rfc/rfc3454.txt),
- * and then with Punycode (http://www.ietf.org/rfc/rfc3492.txt).
- * Implementations of IDNA MUST fully implement Nameprep and Punycode;
- * neither Nameprep nor Punycode are optional.
- * The input and output of ToASCII and ToUnicode operations are Unicode
- * and are designed to be chainable, i.e., applying ToASCII or ToUnicode operations
- * multiple times to an input string will yield the same result as applying the operation
- * once.
- * ToUnicode(ToUnicode(ToUnicode...(ToUnicode(string)))) == ToUnicode(string) 
- * ToASCII(ToASCII(ToASCII...(ToASCII(string))) == ToASCII(string).
- *
- * @param src               Input UChar array containing label in Unicode.
- * @param srcLength         Number of UChars in src, or -1 if NUL-terminated.
- * @param dest              Output UChar array with ASCII (ACE encoded) label.
- * @param destCapacity      Size of dest.
- * @param options           A bit set of options:
- *
- *  - UIDNA_DEFAULT             Use default options, i.e., do not process unassigned code points
- *                              and do not use STD3 ASCII rules
- *                              If unassigned code points are found the operation fails with 
- *                              U_UNASSIGNED_ERROR error code.
- *
- *  - UIDNA_ALLOW_UNASSIGNED    Unassigned values can be converted to ASCII for query operations
- *                              If this option is set, the unassigned code points are in the input 
- *                              are treated as normal Unicode code points.
- *
- *  - UIDNA_USE_STD3_RULES      Use STD3 ASCII rules for host name syntax restrictions
- *                              If this option is set and the input does not satisfy STD3 rules,  
- *                              the operation will fail with U_IDNA_STD3_ASCII_RULES_ERROR

- * limit, and previous() only checks the current index against the start,
- * to see if the iterator already reached the end of the iteration range.

- * The assumption - in all iterators - is that the index is moved via the API,

- * user code that knows enough about the iterator implementation to set valid

- * \file
- * \brief  C API: Locale 
- *
- * <h2> ULoc C API for Locale </h2>
- * A <code>Locale</code> represents a specific geographical, political,
- * or cultural region. An operation that requires a <code>Locale</code> to perform
- * its task is called <em>locale-sensitive</em> and uses the <code>Locale</code>
- * to tailor information for the user. For example, displaying a number
- * is a locale-sensitive operation--the number should be formatted
- * according to the customs/conventions of the user's native country,
- * region, or culture.  In the C APIs, a locales is simply a const char string.
- *
- * <P>
- * You create a <code>Locale</code> with one of the three options listed below.
- * Each of the component is separated by '_' in the locale string.
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- *       newLanguage
- * 
- *       newLanguage + newCountry
- * 
- *       newLanguage + newCountry + newVariant
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * The first option is a valid <STRONG>ISO
- * Language Code.</STRONG> These codes are the lower-case two-letter
- * codes as defined by ISO-639.
- * You can find a full list of these codes at a number of sites, such as:
- * <BR><a href ="http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt">
- * http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt</a>
- *
- * <P>
- * The second option includes an additional <STRONG>ISO Country
- * Code.</STRONG> These codes are the upper-case two-letter codes
- * as defined by ISO-3166.
- * You can find a full list of these codes at a number of sites, such as:
- * <BR><a href="http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html">
- * http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html</a>
- *
- * <P>
- * The third option requires another additional information--the 
- * <STRONG>Variant.</STRONG>
- * The Variant codes are vendor and browser-specific.
- * For example, use WIN for Windows, MAC for Macintosh, and POSIX for POSIX.
- * Where there are two variants, separate them with an underscore, and
- * put the most important one first. For
- * example, a Traditional Spanish collation might be referenced, with
- * "ES", "ES", "Traditional_WIN".
- *
- * <P>
- * Because a <code>Locale</code> is just an identifier for a region,
- * no validity check is performed when you specify a <code>Locale</code>.
- * If you want to see whether particular resources are available for the
- * <code>Locale</code> you asked for, you must query those resources. For
- * example, ask the <code>UNumberFormat</code> for the locales it supports
- * using its <code>getAvailable</code> method.
- * <BR><STRONG>Note:</STRONG> When you ask for a resource for a particular
- * locale, you get back the best available match, not necessarily
- * precisely what you asked for. For more information, look at
- * <code>UResourceBundle</code>.
- *
- * <P>
- * The <code>Locale</code> provides a number of convenient constants
- * that you can use to specify the commonly used
- * locales. For example, the following refers to a locale
- * for the United States:
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- *       ULOC_US
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- *
- * <P>
- * Once you've specified a locale you can query it for information about
- * itself. Use <code>uloc_getCountry</code> to get the ISO Country Code and
- * <code>uloc_getLanguage</code> to get the ISO Language Code. You can
- * use <code>uloc_getDisplayCountry</code> to get the
- * name of the country suitable for displaying to the user. Similarly,
- * you can use <code>uloc_getDisplayLanguage</code> to get the name of
- * the language suitable for displaying to the user. Interestingly,
- * the <code>uloc_getDisplayXXX</code> methods are themselves locale-sensitive
- * and have two versions: one that uses the default locale and one
- * that takes a locale as an argument and displays the name or country in
- * a language appropriate to that locale.
- *
- * <P>
- * The ICU provides a number of services that perform locale-sensitive
- * operations. For example, the <code>unum_xxx</code> functions format
- * numbers, currency, or percentages in a locale-sensitive manner. 
- * </P>
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- *     UErrorCode success = U_ZERO_ERROR;
- *     UNumberFormat *nf;
- *     const char* myLocale = "fr_FR";
- * 
- *     nf = unum_open( UNUM_DEFAULT, NULL, success );          
- *     unum_close(nf);
- *     nf = unum_open( UNUM_CURRENCY, NULL, success );
- *     unum_close(nf);
- *     nf = unum_open( UNUM_PERCENT, NULL, success );   
- *     unum_close(nf);
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * Each of these methods has two variants; one with an explicit locale
- * and one without; the latter using the default locale.
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code 
- * 
- *     nf = unum_open( UNUM_DEFAULT, myLocale, success );          
- *     unum_close(nf);
- *     nf = unum_open( UNUM_CURRENCY, myLocale, success );
- *     unum_close(nf);
- *     nf = unum_open( UNUM_PERCENT, myLocale, success );   
- *     unum_close(nf);
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * A <code>Locale</code> is the mechanism for identifying the kind of services
- * (<code>UNumberFormat</code>) that you would like to get. The locale is
- * <STRONG>just</STRONG> a mechanism for identifying these services.
- *
- * <P>
- * Each international service that performs locale-sensitive operations 
- * allows you
- * to get all the available objects of that type. You can sift
- * through these objects by language, country, or variant,
- * and use the display names to present a menu to the user.
- * For example, you can create a menu of all the collation objects
- * suitable for a given language. Such classes implement these
- * three class methods:
- * \htmlonly<blockquote>\endhtmlonly
- * <pre>
- * \code
- *       const char* uloc_getAvailable(int32_t index);
- *       int32_t uloc_countAvailable();
- *       int32_t
- *       uloc_getDisplayName(const char* localeID,
- *                 const char* inLocaleID, 
- *                 UChar* result,
- *                 int32_t maxResultSize,
- *                  UErrorCode* err);
- * 
- * \endcode
- * </pre>
- * \htmlonly</blockquote>\endhtmlonly
- * <P>
- * Concerning POSIX/RFC1766 Locale IDs, 
- *  the getLanguage/getCountry/getVariant/getName functions do understand
- * the POSIX type form of  language_COUNTRY.ENCODING\@VARIANT
- * and if there is not an ICU-stype variant, uloc_getVariant() for example
- * will return the one listed after the \@at sign. As well, the hyphen
- * "-" is recognized as a country/variant separator similarly to RFC1766.
- * So for example, "en-us" will be interpreted as en_US.  
- * As a result, uloc_getName() is far from a no-op, and will have the
- * effect of converting POSIX/RFC1766 IDs into ICU form, although it does
- * NOT map any of the actual codes (i.e. russian->ru) in any way.
- * Applications should call uloc_getName() at the point where a locale ID
- * is coming from an external source (user entry, OS, web browser)
- * and pass the resulting string to other ICU functions.  For example,
- * don't use de-de\@EURO as an argument to resourcebundle.

- * \file
- * \brief C API: MessageFormat
- *
- * <h2>MessageFormat C API </h2>
- *
- * <p>MessageFormat prepares strings for display to users,
- * with optional arguments (variables/placeholders).
- * The arguments can occur in any order, which is necessary for translation
- * into languages with different grammars.
- *
- * <p>The opaque UMessageFormat type is a thin C wrapper around
- * a C++ MessageFormat. It is constructed from a <em>pattern</em> string
- * with arguments in {curly braces} which will be replaced by formatted values.
- *
- * <p>Currently, the C API supports only numbered arguments.
- *
- * <p>For details about the pattern syntax and behavior,
- * especially about the ASCII apostrophe vs. the
- * real apostrophe (single quote) character \htmlonly&#x2019;\endhtmlonly (U+2019),
- * see the C++ MessageFormat class documentation.
- *
- * <p>Here are some examples of C API usage:
- * Example 1:
- * <pre>
- * \code
- *     UChar *result, *tzID, *str;
- *     UChar pattern[100];
- *     int32_t resultLengthOut, resultlength;
- *     UCalendar *cal;
- *     UDate d1;
- *     UDateFormat *def1;
- *     UErrorCode status = U_ZERO_ERROR;
- *
- *     str=(UChar*)malloc(sizeof(UChar) * (strlen("disturbance in force") +1));
- *     u_uastrcpy(str, "disturbance in force");
- *     tzID=(UChar*)malloc(sizeof(UChar) * 4);
- *     u_uastrcpy(tzID, "PST");
- *     cal=ucal_open(tzID, u_strlen(tzID), "en_US", UCAL_TRADITIONAL, &status);
- *     ucal_setDateTime(cal, 1999, UCAL_MARCH, 18, 0, 0, 0, &status);
- *     d1=ucal_getMillis(cal, &status);
- *     u_uastrcpy(pattern, "On {0, date, long}, there was a {1} on planet {2,number,integer}");
- *     resultlength=0;
- *     resultLengthOut=u_formatMessage( "en_US", pattern, u_strlen(pattern), NULL, resultlength, &status, d1, str, 7);
- *     if(status==U_BUFFER_OVERFLOW_ERROR){
- *         status=U_ZERO_ERROR;
- *         resultlength=resultLengthOut+1;
- *         result=(UChar*)realloc(result, sizeof(UChar) * resultlength);
- *         u_formatMessage( "en_US", pattern, u_strlen(pattern), result, resultlength, &status, d1, str, 7);
- *     }
- *     printf("%s\n", austrdup(result) );//austrdup( a function used to convert UChar* to char*)
- *     //output>: "On March 18, 1999, there was a disturbance in force on planet 7
- * \endcode
- * </pre>
- * Typically, the message format will come from resources, and the
- * arguments will be dynamically set at runtime.
- * <P>
- * Example 2:
- * <pre>
- * \code
- *     UChar* str;
- *     UErrorCode status = U_ZERO_ERROR;
- *     UChar *result;
- *     UChar pattern[100];
- *     int32_t resultlength, resultLengthOut, i;
- *     double testArgs= { 100.0, 1.0, 0.0};
- *
- *     str=(UChar*)malloc(sizeof(UChar) * 10);
- *     u_uastrcpy(str, "MyDisk");
- *     u_uastrcpy(pattern, "The disk {1} contains {0,choice,0#no files|1#one file|1<{0,number,integer} files}");
- *     for(i=0; i<3; i++){
- *       resultlength=0; 
- *       resultLengthOut=u_formatMessage( "en_US", pattern, u_strlen(pattern), NULL, resultlength, &status, testArgs[i], str); 
- *       if(status==U_BUFFER_OVERFLOW_ERROR){
- *         status=U_ZERO_ERROR;
- *         resultlength=resultLengthOut+1;
- *         result=(UChar*)malloc(sizeof(UChar) * resultlength);
- *         u_formatMessage( "en_US", pattern, u_strlen(pattern), result, resultlength, &status, testArgs[i], str);
- *       }
- *       printf("%s\n", austrdup(result) );  //austrdup( a function used to convert UChar* to char*)
- *       free(result);
- *     }
- *     // output, with different testArgs:
- *     // output: The disk "MyDisk" contains 100 files.
- *     // output: The disk "MyDisk" contains one file.
- *     // output: The disk "MyDisk" contains no files.
- * \endcode
- *  </pre>
- *
- *
- * Example 3:
- * <pre>
- * \code
- * UChar* str;
- * UChar* str1;
- * UErrorCode status = U_ZERO_ERROR;
- * UChar *result;
- * UChar pattern[100];
- * UChar expected[100];
- * int32_t resultlength,resultLengthOut;
-
- * str=(UChar*)malloc(sizeof(UChar) * 25);
- * u_uastrcpy(str, "Kirti");
- * str1=(UChar*)malloc(sizeof(UChar) * 25);
- * u_uastrcpy(str1, "female");
- * log_verbose("Testing message format with Select test #1\n:");
- * u_uastrcpy(pattern, "{0} est {1, select, female {all\\u00E9e} other {all\\u00E9}} \\u00E0 Paris.");

-/**
- * A mutable set of Unicode characters and multicharacter strings.  Objects of this class
- * represent <em>character classes</em> used in regular expressions.
- * A character specifies a subset of Unicode code points.  Legal
- * code points are U+0000 to U+10FFFF, inclusive.
- *
- * <p>The UnicodeSet class is not designed to be subclassed.
- *
- * <p><code>UnicodeSet</code> supports two APIs. The first is the
- * <em>operand</em> API that allows the caller to modify the value of
- * a <code>UnicodeSet</code> object. It conforms to Java 2's
- * <code>java.util.Set</code> interface, although
- * <code>UnicodeSet</code> does not actually implement that
- * interface. All methods of <code>Set</code> are supported, with the
- * modification that they take a character range or single character
- * instead of an <code>Object</code>, and they take a
- * <code>UnicodeSet</code> instead of a <code>Collection</code>.  The
- * operand API may be thought of in terms of boolean logic: a boolean
- * OR is implemented by <code>add</code>, a boolean AND is implemented
- * by <code>retain</code>, a boolean XOR is implemented by
- * <code>complement</code> taking an argument, and a boolean NOT is
- * implemented by <code>complement</code> with no argument.  In terms
- * of traditional set theory function names, <code>add</code> is a
- * union, <code>retain</code> is an intersection, <code>remove</code>
- * is an asymmetric difference, and <code>complement</code> with no
- * argument is a set complement with respect to the superset range
- * <code>MIN_VALUE-MAX_VALUE</code>
- *
- * <p>The second API is the
- * <code>applyPattern()</code>/<code>toPattern()</code> API from the
- * <code>java.text.Format</code>-derived classes.  Unlike the
- * methods that add characters, add categories, and control the logic
- * of the set, the method <code>applyPattern()</code> sets all
- * attributes of a <code>UnicodeSet</code> at once, based on a
- * string pattern.
- *
- * <p><b>Pattern syntax</b></p>
- *
- * Patterns are accepted by the constructors and the
- * <code>applyPattern()</code> methods and returned by the
- * <code>toPattern()</code> method.  These patterns follow a syntax
- * similar to that employed by version 8 regular expression character
- * classes.  Here are some simple examples:
- *
- * \htmlonly<blockquote>\endhtmlonly
- *   <table>
- *     <tr align="top">
- *       <td nowrap valign="top" align="left"><code>[]</code></td>

- * Any character may be preceded by a backslash in order to remove any special
- * meaning.  White space characters, as defined by UCharacter.isWhitespace(), are
- * ignored, unless they are escaped.
- *
- * <p>Property patterns specify a set of characters having a certain
- * property as defined by the Unicode standard.  Both the POSIX-like
- * "[:Lu:]" and the Perl-like syntax "\\p{Lu}" are recognized.  For a
- * complete list of supported property patterns, see the User's Guide
- * for UnicodeSet at
- * <a href="http://icu-project.org/userguide/unicodeSet.html">
- * http://icu-project.org/userguide/unicodeSet.html</a>.
- * Actual determination of property data is defined by the underlying
- * Unicode database as implemented by UCharacter.
- *
- * <p>Patterns specify individual characters, ranges of characters, and
- * Unicode property sets.  When elements are concatenated, they
- * specify their union.  To complement a set, place a '^' immediately
- * after the opening '['.  Property patterns are inverted by modifying
- * their delimiters; "[:^foo]" and "\\P{foo}".  In any other location,
- * '^' has no special meaning.
- *
- * <p>Ranges are indicated by placing two a '-' between two
- * characters, as in "a-z".  This specifies the range of all
- * characters from the left to the right, in Unicode order.  If the
- * left character is greater than or equal to the
- * right character it is a syntax error.  If a '-' occurs as the first
- * character after the opening '[' or '[^', or if it occurs as the
- * last character before the closing ']', then it is taken as a
- * literal.  Thus "[a\-b]", "[-ab]", and "[ab-]" all indicate the same
- * set of three characters, 'a', 'b', and '-'.
- *
- * <p>Sets may be intersected using the '&' operator or the asymmetric
- * set difference may be taken using the '-' operator, for example,
- * "[[:L:]&[\\u0000-\\u0FFF]]" indicates the set of all Unicode letters
- * with values less than 4096.  Operators ('&' and '|') have equal
- * precedence and bind left-to-right.  Thus
- * "[[:L:]-[a-z]-[\\u0100-\\u01FF]]" is equivalent to
- * "[[[:L:]-[a-z]]-[\\u0100-\\u01FF]]".  This only really matters for
- * difference; intersection is commutative.

- * \def UNISTR_OBJECT_SIZE
- * Desired sizeof(UnicodeString) in bytes.

- * which is a common granularity for heap allocation.
- *
- * Any space inside the object beyond sizeof(vtable pointer) + 2
- * is available for storing short strings inside the object.
- * The bigger the object, the longer a string that can be stored inside the object,
- * without additional heap allocation.
- *
- * Depending on a platform's pointer size, pointer alignment requirements,
- * and struct padding, the compiler will usually round up sizeof(UnicodeString)
- * to 4 * sizeof(pointer) (or 3 * sizeof(pointer) for P128 data models),
- * to hold the fields for heap-allocated strings.
- * Such a minimum size also ensures that the object is easily large enough
- * to hold at least 2 char16_ts, for one supplementary code point (U16_MAX_LENGTH).
- *
- * sizeof(UnicodeString) >= 48 should work for all known platforms.
- *
- * For example, on a 64-bit machine where sizeof(vtable pointer) is 8,
- * sizeof(UnicodeString) = 64 would leave space for
- * (64 - sizeof(vtable pointer) - 2) / U_SIZEOF_UCHAR = (64 - 8 - 2) / 2 = 27
- * char16_ts stored inside the object.
- *
- * The minimum object size on a 64-bit machine would be
- * 4 * sizeof(pointer) = 4 * 8 = 32 bytes,
- * and the internal buffer would hold up to 11 char16_ts in that case.

-/**
- * UnicodeString is a string class that stores Unicode characters directly and provides
- * similar functionality as the Java String and StringBuffer/StringBuilder classes.
- * It is a concrete implementation of the abstract class Replaceable (for transliteration).
- *
- * The UnicodeString equivalent of std::string’s clear() is remove().
- *
- * A UnicodeString may "alias" an external array of characters
- * (that is, point to it, rather than own the array)
- * whose lifetime must then at least match the lifetime of the aliasing object.
- * This aliasing may be preserved when returning a UnicodeString by value,
- * depending on the compiler and the function implementation,
- * via Return Value Optimization (RVO) or the move assignment operator.
- * (However, the copy assignment operator does not preserve aliasing.)
- * For details see the description of storage models at the end of the class API docs
- * and in the User Guide chapter linked from there.
- *
- * The UnicodeString class is not suitable for subclassing.
- *
- * For an overview of Unicode strings in C and C++ see the
- * [User Guide Strings chapter](http://userguide.icu-project.org/strings#TOC-Strings-in-C-C-).
- *
- * In ICU, a Unicode string consists of 16-bit Unicode *code units*.
- * A Unicode character may be stored with either one code unit
- * (the most common case) or with a matched pair of special code units
- * ("surrogates"). The data type for code units is char16_t.
- * For single-character handling, a Unicode character code *point* is a value
- * in the range 0..0x10ffff. ICU uses the UChar32 type for code points.
- *
- * Indexes and offsets into and lengths of strings always count code units, not code points.
- * This is the same as with multi-byte char* strings in traditional string handling.
- * Operations on partial strings typically do not test for code point boundaries.
- * If necessary, the user needs to take care of such boundaries by testing for the code unit
- * values or by using functions like
- * UnicodeString::getChar32Start() and UnicodeString::getChar32Limit()
- * (or, in C, the equivalent macros U16_SET_CP_START() and U16_SET_CP_LIMIT(), see utf.h).
- *
- * UnicodeString methods are more lenient with regard to input parameter values
- * than other ICU APIs. In particular:
- * - If indexes are out of bounds for a UnicodeString object
- *   (< 0 or > length()) then they are "pinned" to the nearest boundary.
- * - If the buffer passed to an insert/append/replace operation is owned by the
- *   target object, e.g., calling str.append(str), an extra copy may take place
- *   to ensure safety.
- * - If primitive string pointer values (e.g., const char16_t * or char *)
- *   for input strings are NULL, then those input string parameters are treated
- *   as if they pointed to an empty string.
- *   However, this is *not* the case for char * parameters for charset names
- *   or other IDs.
- * - Most UnicodeString methods do not take a UErrorCode parameter because
- *   there are usually very few opportunities for failure other than a shortage
- *   of memory, error codes in low-level C++ string methods would be inconvenient,
- *   and the error code as the last parameter (ICU convention) would prevent
- *   the use of default parameter values.
- *   Instead, such methods set the UnicodeString into a "bogus" state
- *   (see isBogus()) if an error occurs.
- *
- * In string comparisons, two UnicodeString objects that are both "bogus"
- * compare equal (to be transitive and prevent endless loops in sorting),
- * and a "bogus" string compares less than any non-"bogus" one.
- *
- * Const UnicodeString methods are thread-safe. Multiple threads can use
- * const methods on the same UnicodeString object simultaneously,
- * but non-const methods must not be called concurrently (in multiple threads)
- * with any other (const or non-const) methods.
- *
- * Similarly, const UnicodeString & parameters are thread-safe.
- * One object may be passed in as such a parameter concurrently in multiple threads.
- * This includes the const UnicodeString & parameters for
- * copy construction, assignment, and cloning.
- *
- * UnicodeString uses several storage methods.
- * String contents can be stored inside the UnicodeString object itself,
- * in an allocated and shared buffer, or in an outside buffer that is "aliased".
- * Most of this is done transparently, but careful aliasing in particular provides
- * significant performance improvements.
- * Also, the internal buffer is accessible via special functions.
- * For details see the
- * [User Guide Strings chapter](http://userguide.icu-project.org/strings#TOC-Maximizing-Performance-with-the-UnicodeString-Storage-Model).

-/**
- * \file
- * \brief C API: Unicode Normalization
- *
- * Old Unicode normalization API.
- *
- * This API has been replaced by the unorm2.h API and is only available
- * for backward compatibility. The functions here simply delegate to the
- * unorm2.h functions, for example unorm2_getInstance() and unorm2_normalize().
- * There is one exception: The new API does not provide a replacement for unorm_compare().
- * Its declaration has been moved to unorm2.h.
- *
- * <code>unorm_normalize</code> transforms Unicode text into an equivalent composed or
- * decomposed form, allowing for easier sorting and searching of text.
- * <code>unorm_normalize</code> supports the standard normalization forms described in
- * <a href="http://www.unicode.org/unicode/reports/tr15/" target="unicode">
- * Unicode Standard Annex #15: Unicode Normalization Forms</a>.
- *
- * Characters with accents or other adornments can be encoded in
- * several different ways in Unicode.  For example, take the character A-acute.
- * In Unicode, this can be encoded as a single character (the
- * "composed" form):
- *
- * \code
- *      00C1    LATIN CAPITAL LETTER A WITH ACUTE
- * \endcode
- *
- * or as two separate characters (the "decomposed" form):
- *
- * \code
- *      0041    LATIN CAPITAL LETTER A
- *      0301    COMBINING ACUTE ACCENT
- * \endcode
- *
- * To a user of your program, however, both of these sequences should be
- * treated as the same "user-level" character "A with acute accent".  When you are searching or
- * comparing text, you must ensure that these two sequences are treated
- * equivalently.  In addition, you must handle characters with more than one
- * accent.  Sometimes the order of a character's combining accents is
- * significant, while in other cases accent sequences in different orders are
- * really equivalent.
- *
- * Similarly, the string "ffi" can be encoded as three separate letters:
- *
- * \code
- *      0066    LATIN SMALL LETTER F
- *      0066    LATIN SMALL LETTER F
- *      0069    LATIN SMALL LETTER I
- * \endcode
- *
- * or as the single character
- *
- * \code
- *      FB03    LATIN SMALL LIGATURE FFI
- * \endcode
- *
- * The ffi ligature is not a distinct semantic character, and strictly speaking
- * it shouldn't be in Unicode at all, but it was included for compatibility
- * with existing character sets that already provided it.  The Unicode standard
- * identifies such characters by giving them "compatibility" decompositions
- * into the corresponding semantic characters.  When sorting and searching, you
- * will often want to use these mappings.
- *
- * <code>unorm_normalize</code> helps solve these problems by transforming text into the
- * canonical composed and decomposed forms as shown in the first example above.
- * In addition, you can have it perform compatibility decompositions so that
- * you can treat compatibility characters the same as their equivalents.
- * Finally, <code>unorm_normalize</code> rearranges accents into the proper canonical
- * order, so that you do not have to worry about accent rearrangement on your
- * own.
- *
- * Form FCD, "Fast C or D", is also designed for collation.
- * It allows to work on strings that are not necessarily normalized
- * with an algorithm (like in collation) that works under "canonical closure", i.e., it treats precomposed
- * characters and their decomposed equivalents the same.
- *
- * It is not a normalization form because it does not provide for uniqueness of representation. Multiple strings
- * may be canonically equivalent (their NFDs are identical) and may all conform to FCD without being identical
- * themselves.
- *
- * The form is defined such that the "raw decomposition", the recursive canonical decomposition of each character,
- * results in a string that is canonically ordered. This means that precomposed characters are allowed for as long
- * as their decompositions do not need canonical reordering.
- *
- * Its advantage for a process like collation is that all NFD and most NFC texts - and many unnormalized texts -
- * already conform to FCD and do not need to be normalized (NFD) for such a process. The FCD quick check will
- * return UNORM_YES for most strings in practice.
- *
- * unorm_normalize(UNORM_FCD) may be implemented with UNORM_NFD.
- *
- * For more details on FCD see the collation design document:
- * http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm
- *
- * ICU collation performs either NFD or FCD normalization automatically if normalization
- * is turned on for the collator object.
- * Beyond collation and string search, normalized strings may be useful for string equivalence comparisons,
- * transliteration/transcription, unique representations, etc.
- *
- * The W3C generally recommends to exchange texts in NFC.
- * Note also that most legacy character encodings use only precomposed forms and often do not
- * encode any combining marks by themselves. For conversion to such character encodings the
- * Unicode text needs to be normalized to NFC.
- * For more usage examples, see the Unicode Standard Annex.

-/**
- * Iterative normalization forward.
- * This function (together with unorm_previous) is somewhat
- * similar to the C++ Normalizer class (see its non-static functions).
- *
- * Iterative normalization is useful when only a small portion of a longer
- * string/text needs to be processed.
- *
- * For example, the likelihood may be high that processing the first 10% of some
- * text will be sufficient to find certain data.
- * Another example: When one wants to concatenate two normalized strings and get a
- * normalized result, it is much more efficient to normalize just a small part of
- * the result around the concatenation place instead of re-normalizing everything.
- *
- * The input text is an instance of the C character iteration API UCharIterator.
- * It may wrap around a simple string, a CharacterIterator, a Replaceable, or any
- * other kind of text object.
- *
- * If a buffer overflow occurs, then the caller needs to reset the iterator to the
- * old index and call the function again with a larger buffer - if the caller cares
- * for the actual output.
- * Regardless of the output buffer, the iterator will always be moved to the next
- * normalization boundary.
- *
- * This function (like unorm_previous) serves two purposes:
- *
- * 1) To find the next boundary so that the normalization of the part of the text
- * from the current position to that boundary does not affect and is not affected
- * by the part of the text beyond that boundary.
- *
- * 2) To normalize the text up to the boundary.
- *
- * The second step is optional, per the doNormalize parameter.
- * It is omitted for operations like string concatenation, where the two adjacent
- * string ends need to be normalized together.
- * In such a case, the output buffer will just contain a copy of the text up to the
- * boundary.
- *
- * pNeededToNormalize is an output-only parameter. Its output value is only defined
- * if normalization was requested (doNormalize) and successful (especially, no
- * buffer overflow).
- * It is useful for operations like a normalizing transliterator, where one would
- * not want to replace a piece of text if it is not modified.
- *
- * If doNormalize==TRUE and pNeededToNormalize!=NULL then *pNeeded... is set TRUE
- * if the normalization was necessary.
- *
- * If doNormalize==FALSE then *pNeededToNormalize will be set to FALSE.
- *
- * If the buffer overflows, then *pNeededToNormalize will be undefined;
- * essentially, whenever U_FAILURE is true (like in buffer overflows), this result
- * will be undefined.
- *
- * @param src The input text in the form of a C character iterator.
- * @param dest The output buffer; can be NULL if destCapacity==0 for pure preflighting.
- * @param destCapacity The number of UChars that fit into dest.
- * @param mode The normalization mode.
- * @param options The normalization options, ORed together (0 for no options).
- * @param doNormalize Indicates if the source text up to the next boundary
- *                    is to be normalized (TRUE) or just copied (FALSE).
- * @param pNeededToNormalize Output flag indicating if the normalization resulted in
- *                           different text from the input.
- *                           Not defined if an error occurs including buffer overflow.
- *                           Always FALSE if !doNormalize.
- * @param pErrorCode ICU error code in/out parameter.
- *                   Must fulfill U_SUCCESS before the function call.
- * @return Length of output (number of UChars) when successful or buffer overflow.

- * \file
- * \brief C API: Compatibility APIs for number formatting.
- *
- * <h2> Number Format C API </h2>
- * 
- * <p><strong>IMPORTANT:</strong> New users with are strongly encouraged to
- * see if unumberformatter.h fits their use case.  Although not deprecated,
- * this header is provided for backwards compatibility only.
- *
- * Number Format C API  Provides functions for
- * formatting and parsing a number.  Also provides methods for
- * determining which locales have number formats, and what their names
- * are.
- * <P>
- * UNumberFormat helps you to format and parse numbers for any locale.
- * Your code can be completely independent of the locale conventions
- * for decimal points, thousands-separators, or even the particular
- * decimal digits used, or whether the number format is even decimal.
- * There are different number format styles like decimal, currency,
- * percent and spellout.
- * <P>
- * To format a number for the current Locale, use one of the static
- * factory methods:
- * <pre>
- * \code
- *    UChar myString[20];
- *    double myNumber = 7.0;
- *    UErrorCode status = U_ZERO_ERROR;
- *    UNumberFormat* nf = unum_open(UNUM_DEFAULT, NULL, -1, NULL, NULL, &status);
- *    unum_formatDouble(nf, myNumber, myString, 20, NULL, &status);
- *    printf(" Example 1: %s\n", austrdup(myString) ); //austrdup( a function used to convert UChar* to char*)
- * \endcode
- * </pre>
- * If you are formatting multiple numbers, it is more efficient to get
- * the format and use it multiple times so that the system doesn't
- * have to fetch the information about the local language and country
- * conventions multiple times.
- * <pre>
- * \code
- * uint32_t i, resultlength, reslenneeded;
- * UErrorCode status = U_ZERO_ERROR;
- * UFieldPosition pos;
- * uint32_t a[] = { 123, 3333, -1234567 };
- * const uint32_t a_len = sizeof(a) / sizeof(a[0]);
- * UNumberFormat* nf;
- * UChar* result = NULL;
- *
- * nf = unum_open(UNUM_DEFAULT, NULL, -1, NULL, NULL, &status);
- * for (i = 0; i < a_len; i++) {
- *    resultlength=0;
- *    reslenneeded=unum_format(nf, a[i], NULL, resultlength, &pos, &status);
- *    result = NULL;
- *    if(status==U_BUFFER_OVERFLOW_ERROR){
- *       status=U_ZERO_ERROR;
- *       resultlength=reslenneeded+1;
- *       result=(UChar*)malloc(sizeof(UChar) * resultlength);
- *       unum_format(nf, a[i], result, resultlength, &pos, &status);
- *    }
- *    printf( " Example 2: %s\n", austrdup(result));
- *    free(result);
- * }
- * \endcode
- * </pre>
- * To format a number for a different Locale, specify it in the
- * call to unum_open().
- * <pre>
- * \code
- *     UNumberFormat* nf = unum_open(UNUM_DEFAULT, NULL, -1, "fr_FR", NULL, &success)
- * \endcode
- * </pre>
- * You can use a NumberFormat API unum_parse() to parse.
- * <pre>
- * \code
- *    UErrorCode status = U_ZERO_ERROR;
- *    int32_t pos=0;
- *    int32_t num;
- *    num = unum_parse(nf, str, u_strlen(str), &pos, &status);
- * \endcode

- * Use UNUM_DECIMAL to get the normal number format for that country.

-/**
- * \file
- * \brief C-compatible API for localized number formatting; not recommended for C++.
- *
- * This is the C-compatible version of the NumberFormatter API introduced in ICU 60. C++ users should
- * include unicode/numberformatter.h and use the proper C++ APIs.
- *
- * The C API accepts a number skeleton string for specifying the settings for formatting, which covers a
- * very large subset of all possible number formatting features. For more information on number skeleton
- * strings, see unicode/numberformatter.h.
- *
- * When using UNumberFormatter, which is treated as immutable, the results are exported to a mutable
- * UFormattedNumber object, which you subsequently use for populating your string buffer or iterating over
- * the fields.
- *
- * Example code:
- * <pre>
- * // Setup:
- * UErrorCode ec = U_ZERO_ERROR;
- * UNumberFormatter* uformatter = unumf_openForSkeletonAndLocale(u"precision-integer", -1, "en", &ec);
- * UFormattedNumber* uresult = unumf_openResult(&ec);
- * if (U_FAILURE(ec)) { return; }
- *
- * // Format a double:
- * unumf_formatDouble(uformatter, 5142.3, uresult, &ec);
- * if (U_FAILURE(ec)) { return; }
- *
- * // Export the string to a malloc'd buffer:
- * int32_t len = unumf_resultToString(uresult, NULL, 0, &ec);
- * // at this point, ec == U_BUFFER_OVERFLOW_ERROR
- * ec = U_ZERO_ERROR;
- * UChar* buffer = (UChar*) malloc((len+1)*sizeof(UChar));
- * unumf_resultToString(uresult, buffer, len+1, &ec);
- * if (U_FAILURE(ec)) { return; }
- * // buffer should equal "5,142"
- *
- * // Cleanup:
- * unumf_close(uformatter);
- * unumf_closeResult(uresult);
- * free(buffer);
- * </pre>
- *
- * If you are a C++ user linking against the C libraries, you can use the LocalPointer versions of these
- * APIs. The following example uses LocalPointer with the decimal number and field position APIs:
- *
- * <pre>
- * // Setup:
- * LocalUNumberFormatterPointer uformatter(unumf_openForSkeletonAndLocale(u"percent", -1, "en", &ec));
- * LocalUFormattedNumberPointer uresult(unumf_openResult(&ec));
- * if (U_FAILURE(ec)) { return; }
- *
- * // Format a decimal number:
- * unumf_formatDecimal(uformatter.getAlias(), "9.87E-3", -1, uresult.getAlias(), &ec);
- * if (U_FAILURE(ec)) { return; }
- *
- * // Get the location of the percent sign:
- * UFieldPosition ufpos = {UNUM_PERCENT_FIELD, 0, 0};
- * unumf_resultNextFieldPosition(uresult.getAlias(), &ufpos, &ec);
- * // ufpos should contain beginIndex=7 and endIndex=8 since the string is "0.00987%"
- *
- * // No need to do any cleanup since we are using LocalPointer.
- * </pre>

- * \file
- * \brief C API: UNumberingSystem, information about numbering systems
- *
- * Defines numbering systems. A numbering system describes the scheme by which 
- * numbers are to be presented to the end user. In its simplest form, a numbering
- * system describes the set of digit characters that are to be used to display
- * numbers, such as Western digits, Thai digits, Arabic-Indic digits, etc., in a
- * positional numbering system with a specified radix (typically 10).
- * More complicated numbering systems are algorithmic in nature, and require use
- * of an RBNF formatter (rule based number formatter), in order to calculate
- * the characters to be displayed for a given number. Examples of algorithmic
- * numbering systems include Roman numerals, Chinese numerals, and Hebrew numerals.
- * Formatting rules for many commonly used numbering systems are included in
- * the ICU package, based on the numbering system rules defined in CLDR.
- * Alternate numbering systems can be specified to a locale by using the
- * numbers locale keyword.

-/**
- * \file
- * \brief C API: URegion (territory containment and mapping)
- *
- * URegion objects represent data associated with a particular Unicode Region Code, also known as a 
- * Unicode Region Subtag, which is defined based upon the BCP 47 standard. These include:
- * * Two-letter codes defined by ISO 3166-1, with special LDML treatment of certain private-use or
- *   reserved codes;
- * * A subset of 3-digit numeric codes defined by UN M.49.
- * URegion objects can also provide mappings to and from additional codes. There are different types
- * of regions that are important to distinguish:
- * <p>
- * Macroregion - A code for a "macro geographical (continental) region, geographical sub-region, or 
- * selected economic and other grouping" as defined in UN M.49. These are typically 3-digit codes,
- * but contain some 2-letter codes for LDML extensions, such as "QO" for Outlying Oceania.
- * Macroregions are represented in ICU by one of three region types: WORLD (code 001),
- * CONTINENTS (regions contained directly by WORLD), and SUBCONTINENTS (regions contained directly
- * by a continent ).
- * <p>
- * TERRITORY - A Region that is not a Macroregion. These are typically codes for countries, but also
- * include areas that are not separate countries, such as the code "AQ" for Antarctica or the code 
- * "HK" for Hong Kong (SAR China). Overseas dependencies of countries may or may not have separate 
- * codes. The codes are typically 2-letter codes aligned with ISO 3166, but BCP47 allows for the use
- * of 3-digit codes in the future.
- * <p>
- * UNKNOWN - The code ZZ is defined by Unicode LDML for use in indicating that region is unknown,
- * or that the value supplied as a region was invalid.
- * <p>
- * DEPRECATED - Region codes that have been defined in the past but are no longer in modern usage,
- * usually due to a country splitting into multiple territories or changing its name.
- * <p>
- * GROUPING - A widely understood grouping of territories that has a well defined membership such
- * that a region code has been assigned for it.  Some of these are UN M.49 codes that don't fall into 
- * the world/continent/sub-continent hierarchy, while others are just well-known groupings that have
- * their own region code. Region "EU" (European Union) is one such region code that is a grouping.
- * Groupings will never be returned by the uregion_getContainingRegion, since a different type of region
- * (WORLD, CONTINENT, or SUBCONTINENT) will always be the containing region instead.
- *
- * URegion objects are const/immutable, owned and maintained by ICU itself, so there are not functions
- * to open or close them.

- * \file
- * \brief C API: URelativeDateTimeFormatter, relative date formatting of unit + numeric offset.
- *
- * Provides simple formatting of relative dates, in two ways
- * <ul>
- *   <li>relative dates with a quantity e.g "in 5 days"</li>
- *   <li>relative dates without a quantity e.g "next Tuesday"</li>
- * </ul>
- * <p>
- * This does not provide compound formatting for multiple units,
- * other than the ability to combine a time string with a relative date,
- * as in "next Tuesday at 3:45 PM". It also does not provide support
- * for determining which unit to use, such as deciding between "in 7 days"
- * and "in 1 week".

-/**
- * Constants for ISO 15924 script codes.
- *
- * The current set of script code constants supports at least all scripts
- * that are encoded in the version of Unicode which ICU currently supports.
- * The names of the constants are usually derived from the
- * Unicode script property value aliases.
- * See UAX #24 Unicode Script Property (http://www.unicode.org/reports/tr24/)
- * and http://www.unicode.org/Public/UCD/latest/ucd/PropertyValueAliases.txt .
- *
- * In addition, constants for many ISO 15924 script codes
- * are included, for use with language tags, CLDR data, and similar.
- * Some of those codes are not used in the Unicode Character Database (UCD).
- * For example, there are no characters that have a UCD script property value of
- * Hans or Hant. All Han ideographs have the Hani script property value in Unicode.
- *
- * Private-use codes Qaaa..Qabx are not included, except as used in the UCD or in CLDR.
- *
- * Starting with ICU 55, script codes are only added when their scripts
- * have been or will certainly be encoded in Unicode,
- * and have been assigned Unicode script property value aliases,
- * to ensure that their script names are stable and match the names of the constants.
- * Script codes like Latf and Aran that are not subject to separate encoding
- * may be added at any time.
- *
- * @stable ICU 2.2

-/**
- * \file
- * \brief C API: StringSearch
- *
- * C APIs for an engine that provides language-sensitive text searching based 
- * on the comparison rules defined in a <tt>UCollator</tt> data struct,
- * see <tt>ucol.h</tt>. This ensures that language eccentricity can be 
- * handled, e.g. for the German collator, characters &szlig; and SS will be matched 
- * if case is chosen to be ignored. 
- * See the <a href="http://source.icu-project.org/repos/icu/icuhtml/trunk/design/collation/ICU_collation_design.htm">
- * "ICU Collation Design Document"</a> for more information.
- * <p> 
- * The implementation may use a linear search or a modified form of the Boyer-Moore
- * search; for more information on the latter see 
- * <a href="http://icu-project.org/docs/papers/efficient_text_searching_in_java.html">
- * "Efficient Text Searching in Java"</a>, published in <i>Java Report</i> 
- * in February, 1999.
- * <p>
- * There are 2 match options for selection:<br>
- * Let S' be the sub-string of a text string S between the offsets start and 
- * end <start, end>.
- * <br>
- * A pattern string P matches a text string S at the offsets <start, end> 
- * if
- * <pre> 
- * option 1. Some canonical equivalent of P matches some canonical equivalent 
- *           of S'
- * option 2. P matches S' and if P starts or ends with a combining mark, 
- *           there exists no non-ignorable combining mark before or after S' 
- *           in S respectively. 
- * </pre>
- * Option 2. will be the default.
- * <p>
- * This search has APIs similar to that of other text iteration mechanisms 
- * such as the break iterators in <tt>ubrk.h</tt>. Using these 
- * APIs, it is easy to scan through text looking for all occurrences of 
- * a given pattern. This search iterator allows changing of direction by 
- * calling a <tt>reset</tt> followed by a <tt>next</tt> or <tt>previous</tt>. 
- * Though a direction change can occur without calling <tt>reset</tt> first,  
- * this operation comes with some speed penalty.
- * Generally, match results in the forward direction will match the result 
- * matches in the backwards direction in the reverse order
- * <p>
- * <tt>usearch.h</tt> provides APIs to specify the starting position 
- * within the text string to be searched, e.g. <tt>usearch_setOffset</tt>,
- * <tt>usearch_preceding</tt> and <tt>usearch_following</tt>. Since the 
- * starting position will be set as it is specified, please take note that 
- * there are some dangerous positions which the search may render incorrect 
- * results:
- * <ul>
- * <li> The midst of a substring that requires normalization.
- * <li> If the following match is to be found, the position should not be the
- *      second character which requires to be swapped with the preceding 
- *      character. Vice versa, if the preceding match is to be found, 
- *      position to search from should not be the first character which 
- *      requires to be swapped with the next character. E.g certain Thai and
- *      Lao characters require swapping.
- * <li> If a following pattern match is to be found, any position within a 
- *      contracting sequence except the first will fail. Vice versa if a 
- *      preceding pattern match is to be found, a invalid starting point 
- *      would be any character within a contracting sequence except the last.
- * </ul>
- * <p>
- * A breakiterator can be used if only matches at logical breaks are desired.
- * Using a breakiterator will only give you results that exactly matches the
- * boundaries given by the breakiterator. For instance the pattern "e" will
- * not be found in the string "\u00e9" if a character break iterator is used.
- * <p>
- * Options are provided to handle overlapping matches. 
- * E.g. In English, overlapping matches produces the result 0 and 2 
- * for the pattern "abab" in the text "ababab", where else mutually 
- * exclusive matches only produce the result of 0.
- * <p>
- * Options are also provided to implement "asymmetric search" as described in
- * <a href="http://www.unicode.org/reports/tr10/#Asymmetric_Search">
- * UTS #10 Unicode Collation Algorithm</a>, specifically the USearchAttribute
- * USEARCH_ELEMENT_COMPARISON and its values.
- * <p>
- * Though collator attributes will be taken into consideration while 
- * performing matches, there are no APIs here for setting and getting the 
- * attributes. These attributes can be set by getting the collator
- * from <tt>usearch_getCollator</tt> and using the APIs in <tt>ucol.h</tt>.
- * Lastly to update String Search to the new collator attributes, 
- * usearch_reset() has to be called.
- * <p> 
- * Restriction: <br>
- * Currently there are no composite characters that consists of a
- * character with combining class > 0 before a character with combining 
- * class == 0. However, if such a character exists in the future, the 
- * search mechanism does not guarantee the results for option 1.
- * 
- * <p>
- * Example of use:<br>
- * <pre><code>
- * char *tgtstr = "The quick brown fox jumped over the lazy fox";
- * char *patstr = "fox";
- * UChar target[64];
- * UChar pattern[16];
- * UErrorCode status = U_ZERO_ERROR;
- * u_uastrcpy(target, tgtstr);
- * u_uastrcpy(pattern, patstr);
- *
- * UStringSearch *search = usearch_open(pattern, -1, target, -1, "en_US", 
- *                                  NULL, &status);
- * if (U_SUCCESS(status)) {
- *     for (int pos = usearch_first(search, &status); 
- *          pos != USEARCH_DONE; 
- *          pos = usearch_next(search, &status))
- *     {
- *         printf("Found match at %d pos, length is %d\n", pos, 
- *                                        usearch_getMatchedLength(search));
- *     }
- * }
- *
- * usearch_close(search);
- * </code></pre>

- * Argument values for whether span() and similar functions continue while
- * the current character is contained vs. not contained in the set.
- *
- * The functionality is straightforward for sets with only single code points,
- * without strings (which is the common case):
- * - USET_SPAN_CONTAINED and USET_SPAN_SIMPLE work the same.
- * - USET_SPAN_CONTAINED and USET_SPAN_SIMPLE are inverses of USET_SPAN_NOT_CONTAINED.
- * - span() and spanBack() partition any string the same way when
- *   alternating between span(USET_SPAN_NOT_CONTAINED) and
- *   span(either "contained" condition).
- * - Using a complemented (inverted) set and the opposite span conditions
- *   yields the same results.
- *
- * When a set contains multi-code point strings, then these statements may not
- * be true, depending on the strings in the set (for example, whether they
- * overlap with each other) and the string that is processed.
- * For a set with strings:
- * - The complement of the set contains the opposite set of code points,
- *   but the same set of strings.
- *   Therefore, complementing both the set and the span conditions
- *   may yield different results.
- * - When starting spans at different positions in a string
- *   (span(s, ...) vs. span(s+1, ...)) the ends of the spans may be different
- *   because a set string may start before the later position.
- * - span(USET_SPAN_SIMPLE) may be shorter than
- *   span(USET_SPAN_CONTAINED) because it will not recursively try
- *   all possible paths.
- *   For example, with a set which contains the three strings "xy", "xya" and "ax",
- *   span("xyax", USET_SPAN_CONTAINED) will return 4 but
- *   span("xyax", USET_SPAN_SIMPLE) will return 3.
- *   span(USET_SPAN_SIMPLE) will never be longer than
- *   span(USET_SPAN_CONTAINED).
- * - With either "contained" condition, span() and spanBack() may partition
- *   a string in different ways.
- *   For example, with a set which contains the two strings "ab" and "ba",
- *   and when processing the string "aba",
- *   span() will yield contained/not-contained boundaries of { 0, 2, 3 }
- *   while spanBack() will yield boundaries of { 0, 1, 3 }.
- *
- * Note: If it is important to get the same boundaries whether iterating forward
- * or backward through a string, then either only span() should be used and
- * the boundaries cached for backward operation, or an ICU BreakIterator
- * could be used.
- *
- * Note: Unpaired surrogates are treated like surrogate code points.
- * Similarly, set strings match only on code point boundaries,
- * never in the middle of a surrogate pair.
- * Illegal UTF-8 sequences are treated like U+FFFD.
- * When processing UTF-8 strings, malformed set strings
- * (strings with unpaired surrogates which cannot be converted to UTF-8)
- * are ignored.

- * <p>Text-based shaping means that some character code points in the text are
- * replaced by others depending on the context. It transforms one kind of text
- * into another. In comparison, modern displays for Arabic text select
- * appropriate, context-dependent font glyphs for each text element, which means
- * that they transform text into a glyph vector.</p>
- *
- * <p>Text transformations are necessary when modern display technology is not
- * available or when text needs to be transformed to or from legacy formats that
- * use "shaped" characters. Since the Arabic script is cursive, connecting
- * adjacent letters to each other, computers select images for each letter based
- * on the surrounding letters. This usually results in four images per Arabic
- * letter: initial, middle, final, and isolated forms. In Unicode, on the other
- * hand, letters are normally stored abstract, and a display system is expected
- * to select the necessary glyphs. (This makes searching and other text
- * processing easier because the same letter has only one code.) It is possible
- * to mimic this with text transformations because there are characters in
- * Unicode that are rendered as letters with a specific shape
- * (or cursive connectivity). They were included for interoperability with
- * legacy systems and codepages, and for unsophisticated display systems.</p>
- *
- * <p>A second kind of text transformations is supported for Arabic digits:
- * For compatibility with legacy codepages that only include European digits,
- * it is possible to replace one set of digits by another, changing the
- * character code points. These operations can be performed for either
- * Arabic-Indic Digits (U+0660...U+0669) or Eastern (Extended) Arabic-Indic
- * digits (U+06f0...U+06f9).</p>
- *
- * <p>Some replacements may result in more or fewer characters (code points).
- * By default, this means that the destination buffer may receive text with a
- * length different from the source length. Some legacy systems rely on the
- * length of the text to be constant. They expect extra spaces to be added
- * or consumed either next to the affected character or at the end of the
- * text.</p>
- *
- * <p>For details about the available operations, see the description of the
- * <code>U_SHAPE_...</code> options.</p>
- *
- * @param source The input text.
- *
- * @param sourceLength The number of UChars in <code>source</code>.
- *
- * @param dest The destination buffer that will receive the results of the
- *             requested operations. It may be <code>NULL</code> only if
- *             <code>destSize</code> is 0. The source and destination must not
- *             overlap.
- *
- * @param destSize The size (capacity) of the destination buffer in UChars.
- *                 If <code>destSize</code> is 0, then no output is produced,
- *                 but the necessary buffer size is returned ("preflighting").
- *
- * @param options This is a 32-bit set of flags that specify the operations
- *                that are performed on the input text. If no error occurs,
- *                then the result will always be written to the destination
- *                buffer.
- *
- * @param pErrorCode must be a valid pointer to an error code value,
- *        which must not indicate a failure before the function call.
- *
- * @return The number of UChars written to the destination buffer.
- *         If an error occurred, then no output was written, or it may be
- *         incomplete. If <code>U_BUFFER_OVERFLOW_ERROR</code> is set, then
- *         the return value indicates the necessary destination buffer size.

-/**
- * \file
- * \brief Unicode Security and Spoofing Detection, C API.
- *
- * <p>
- * This class, based on <a href="http://unicode.org/reports/tr36">Unicode Technical Report #36</a> and
- * <a href="http://unicode.org/reports/tr39">Unicode Technical Standard #39</a>, has two main functions:
- *
- * <ol>
- * <li>Checking whether two strings are visually <em>confusable</em> with each other, such as "Harvest" and
- * &quot;&Eta;arvest&quot;, where the second string starts with the Greek capital letter Eta.</li>
- * <li>Checking whether an individual string is likely to be an attempt at confusing the reader (<em>spoof
- * detection</em>), such as "paypal" with some Latin characters substituted with Cyrillic look-alikes.</li>
- * </ol>
- *
- * <p>
- * Although originally designed as a method for flagging suspicious identifier strings such as URLs,
- * <code>USpoofChecker</code> has a number of other practical use cases, such as preventing attempts to evade bad-word
- * content filters.
- *
- * <p>
- * The functions of this class are exposed as C API, with a handful of syntactical conveniences for C++.
- *
- * <h2>Confusables</h2>
- *
- * <p>
- * The following example shows how to use <code>USpoofChecker</code> to check for confusability between two strings:
- *
- * \code{.c}
- * UErrorCode status = U_ZERO_ERROR;
- * UChar* str1 = (UChar*) u"Harvest";
- * UChar* str2 = (UChar*) u"\u0397arvest";  // with U+0397 GREEK CAPITAL LETTER ETA
- *
- * USpoofChecker* sc = uspoof_open(&status);
- * uspoof_setChecks(sc, USPOOF_CONFUSABLE, &status);
- *
- * int32_t bitmask = uspoof_areConfusable(sc, str1, -1, str2, -1, &status);
- * UBool result = bitmask != 0;
- * // areConfusable: 1 (status: U_ZERO_ERROR)
- * printf("areConfusable: %d (status: %s)\n", result, u_errorName(status));
- * uspoof_close(sc);
- * \endcode
- *
- * <p>
- * The call to {@link uspoof_open} creates a <code>USpoofChecker</code> object; the call to {@link uspoof_setChecks}
- * enables confusable checking and disables all other checks; the call to {@link uspoof_areConfusable} performs the
- * confusability test; and the following line extracts the result out of the return value. For best performance,
- * the instance should be created once (e.g., upon application startup), and the efficient
- * {@link uspoof_areConfusable} method can be used at runtime.
- *
- * <p>
- * The type {@link LocalUSpoofCheckerPointer} is exposed for C++ programmers.  It will automatically call
- * {@link uspoof_close} when the object goes out of scope:
- *
- * \code{.cpp}
- * UErrorCode status = U_ZERO_ERROR;
- * LocalUSpoofCheckerPointer sc(uspoof_open(&status));
- * uspoof_setChecks(sc.getAlias(), USPOOF_CONFUSABLE, &status);
- * // ...
- * \endcode
- *
- * UTS 39 defines two strings to be <em>confusable</em> if they map to the same <em>skeleton string</em>. A skeleton can
- * be thought of as a "hash code". {@link uspoof_getSkeleton} computes the skeleton for a particular string, so
- * the following snippet is equivalent to the example above:
- *
- * \code{.c}
- * UErrorCode status = U_ZERO_ERROR;
- * UChar* str1 = (UChar*) u"Harvest";
- * UChar* str2 = (UChar*) u"\u0397arvest";  // with U+0397 GREEK CAPITAL LETTER ETA
- *
- * USpoofChecker* sc = uspoof_open(&status);
- * uspoof_setChecks(sc, USPOOF_CONFUSABLE, &status);
- *
- * // Get skeleton 1
- * int32_t skel1Len = uspoof_getSkeleton(sc, 0, str1, -1, NULL, 0, &status);
- * UChar* skel1 = (UChar*) malloc(++skel1Len * sizeof(UChar));
- * status = U_ZERO_ERROR;
- * uspoof_getSkeleton(sc, 0, str1, -1, skel1, skel1Len, &status);
- *
- * // Get skeleton 2
- * int32_t skel2Len = uspoof_getSkeleton(sc, 0, str2, -1, NULL, 0, &status);
- * UChar* skel2 = (UChar*) malloc(++skel2Len * sizeof(UChar));
- * status = U_ZERO_ERROR;
- * uspoof_getSkeleton(sc, 0, str2, -1, skel2, skel2Len, &status);
- *
- * // Are the skeletons the same?
- * UBool result = u_strcmp(skel1, skel2) == 0;
- * // areConfusable: 1 (status: U_ZERO_ERROR)
- * printf("areConfusable: %d (status: %s)\n", result, u_errorName(status));
- * uspoof_close(sc);
- * free(skel1);
- * free(skel2);
- * \endcode
- *
- * If you need to check if a string is confusable with any string in a dictionary of many strings, rather than calling
- * {@link uspoof_areConfusable} many times in a loop, {@link uspoof_getSkeleton} can be used instead, as shown below:
- *
- * \code{.c}
- * UErrorCode status = U_ZERO_ERROR;
- * #define DICTIONARY_LENGTH 2
- * UChar* dictionary[DICTIONARY_LENGTH] = { (UChar*) u"lorem", (UChar*) u"ipsum" };
- * UChar* skeletons[DICTIONARY_LENGTH];
- * UChar* str = (UChar*) u"1orern";
- *
- * // Setup:
- * USpoofChecker* sc = uspoof_open(&status);
- * uspoof_setChecks(sc, USPOOF_CONFUSABLE, &status);
- * for (size_t i=0; i<DICTIONARY_LENGTH; i++) {
- *     UChar* word = dictionary[i];
- *     int32_t len = uspoof_getSkeleton(sc, 0, word, -1, NULL, 0, &status);
- *     skeletons[i] = (UChar*) malloc(++len * sizeof(UChar));
- *     status = U_ZERO_ERROR;
- *     uspoof_getSkeleton(sc, 0, word, -1, skeletons[i], len, &status);
- * }
- *
- * // Live Check:
- * {
- *     int32_t len = uspoof_getSkeleton(sc, 0, str, -1, NULL, 0, &status);
- *     UChar* skel = (UChar*) malloc(++len * sizeof(UChar));
- *     status = U_ZERO_ERROR;
- *     uspoof_getSkeleton(sc, 0, str, -1, skel, len, &status);
- *     UBool result = FALSE;
- *     for (size_t i=0; i<DICTIONARY_LENGTH; i++) {
- *         result = u_strcmp(skel, skeletons[i]) == 0;
- *         if (result == TRUE) { break; }
- *     }
- *     // Has confusable in dictionary: 1 (status: U_ZERO_ERROR)
- *     printf("Has confusable in dictionary: %d (status: %s)\n", result, u_errorName(status));
- *     free(skel);
- * }
- *
- * for (size_t i=0; i<DICTIONARY_LENGTH; i++) {
- *     free(skeletons[i]);
- * }
- * uspoof_close(sc);
- * \endcode
- *
- * <b>Note:</b> Since the Unicode confusables mapping table is frequently updated, confusable skeletons are <em>not</em>
- * guaranteed to be the same between ICU releases. We therefore recommend that you always compute confusable skeletons
- * at runtime and do not rely on creating a permanent, or difficult to update, database of skeletons.
- *
- * <h2>Spoof Detection</h2>
- *
- * The following snippet shows a minimal example of using <code>USpoofChecker</code> to perform spoof detection on a
- * string:
- *
- * \code{.c}
- * UErrorCode status = U_ZERO_ERROR;
- * UChar* str = (UChar*) u"p\u0430ypal";  // with U+0430 CYRILLIC SMALL LETTER A
- *
- * // Get the default set of allowable characters:
- * USet* allowed = uset_openEmpty();
- * uset_addAll(allowed, uspoof_getRecommendedSet(&status));
- * uset_addAll(allowed, uspoof_getInclusionSet(&status));
- *
- * USpoofChecker* sc = uspoof_open(&status);
- * uspoof_setAllowedChars(sc, allowed, &status);
- * uspoof_setRestrictionLevel(sc, USPOOF_MODERATELY_RESTRICTIVE);
- *
- * int32_t bitmask = uspoof_check(sc, str, -1, NULL, &status);
- * UBool result = bitmask != 0;
- * // fails checks: 1 (status: U_ZERO_ERROR)
- * printf("fails checks: %d (status: %s)\n", result, u_errorName(status));
- * uspoof_close(sc);
- * uset_close(allowed);
- * \endcode
- *
- * As in the case for confusability checking, it is good practice to create one <code>USpoofChecker</code> instance at
- * startup, and call the cheaper {@link uspoof_check} online. We specify the set of
- * allowed characters to be those with type RECOMMENDED or INCLUSION, according to the recommendation in UTS 39.
- *
- * In addition to {@link uspoof_check}, the function {@link uspoof_checkUTF8} is exposed for UTF8-encoded char* strings,
- * and {@link uspoof_checkUnicodeString} is exposed for C++ programmers.
- *
- * If the {@link USPOOF_AUX_INFO} check is enabled, a limited amount of information on why a string failed the checks
- * is available in the returned bitmask.  For complete information, use the {@link uspoof_check2} class of functions
- * with a {@link USpoofCheckResult} parameter:
- *
- * \code{.c}
- * UErrorCode status = U_ZERO_ERROR;
- * UChar* str = (UChar*) u"p\u0430ypal";  // with U+0430 CYRILLIC SMALL LETTER A
- *
- * // Get the default set of allowable characters:
- * USet* allowed = uset_openEmpty();
- * uset_addAll(allowed, uspoof_getRecommendedSet(&status));
- * uset_addAll(allowed, uspoof_getInclusionSet(&status));
- *
- * USpoofChecker* sc = uspoof_open(&status);
- * uspoof_setAllowedChars(sc, allowed, &status);
- * uspoof_setRestrictionLevel(sc, USPOOF_MODERATELY_RESTRICTIVE);
- *
- * USpoofCheckResult* checkResult = uspoof_openCheckResult(&status);
- * int32_t bitmask = uspoof_check2(sc, str, -1, checkResult, &status);
- *
- * int32_t failures1 = bitmask;
- * int32_t failures2 = uspoof_getCheckResultChecks(checkResult, &status);
- * assert(failures1 == failures2);
- * // checks that failed: 0x00000010 (status: U_ZERO_ERROR)
- * printf("checks that failed: %#010x (status: %s)\n", failures1, u_errorName(status));
- *
- * // Cleanup:
- * uspoof_close(sc);
- * uset_close(allowed);
- * uspoof_closeCheckResult(checkResult);
- * \endcode
- *
- * C++ users can take advantage of a few syntactical conveniences.  The following snippet is functionally
- * equivalent to the one above:
- *
- * \code{.cpp}
- * UErrorCode status = U_ZERO_ERROR;
- * UnicodeString str((UChar*) u"p\u0430ypal");  // with U+0430 CYRILLIC SMALL LETTER A
- *
- * // Get the default set of allowable characters:
- * UnicodeSet allowed;
- * allowed.addAll(*uspoof_getRecommendedUnicodeSet(&status));
- * allowed.addAll(*uspoof_getInclusionUnicodeSet(&status));
- *
- * LocalUSpoofCheckerPointer sc(uspoof_open(&status));
- * uspoof_setAllowedChars(sc.getAlias(), allowed.toUSet(), &status);
- * uspoof_setRestrictionLevel(sc.getAlias(), USPOOF_MODERATELY_RESTRICTIVE);
- *
- * LocalUSpoofCheckResultPointer checkResult(uspoof_openCheckResult(&status));
- * int32_t bitmask = uspoof_check2UnicodeString(sc.getAlias(), str, checkResult.getAlias(), &status);
- *
- * int32_t failures1 = bitmask;
- * int32_t failures2 = uspoof_getCheckResultChecks(checkResult.getAlias(), &status);
- * assert(failures1 == failures2);
- * // checks that failed: 0x00000010 (status: U_ZERO_ERROR)
- * printf("checks that failed: %#010x (status: %s)\n", failures1, u_errorName(status));
- *
- * // Explicit cleanup not necessary.
- * \endcode
- *
- * The return value is a bitmask of the checks that failed. In this case, there was one check that failed:
- * {@link USPOOF_RESTRICTION_LEVEL}, corresponding to the fifth bit (16). The possible checks are:
- *
- * <ul>
- * <li><code>RESTRICTION_LEVEL</code>: flags strings that violate the
- * <a href="http://unicode.org/reports/tr39/#Restriction_Level_Detection">Restriction Level</a> test as specified in UTS
- * 39; in most cases, this means flagging strings that contain characters from multiple different scripts.</li>
- * <li><code>INVISIBLE</code>: flags strings that contain invisible characters, such as zero-width spaces, or character
- * sequences that are likely not to display, such as multiple occurrences of the same non-spacing mark.</li>
- * <li><code>CHAR_LIMIT</code>: flags strings that contain characters outside of a specified set of acceptable
- * characters. See {@link uspoof_setAllowedChars} and {@link uspoof_setAllowedLocales}.</li>
- * <li><code>MIXED_NUMBERS</code>: flags strings that contain digits from multiple different numbering systems.</li>
- * </ul>
- *
- * <p>
- * These checks can be enabled independently of each other. For example, if you were interested in checking for only the
- * INVISIBLE and MIXED_NUMBERS conditions, you could do:
- *
- * \code{.c}
- * UErrorCode status = U_ZERO_ERROR;
- * UChar* str = (UChar*) u"8\u09EA";  // 8 mixed with U+09EA BENGALI DIGIT FOUR
- *
- * USpoofChecker* sc = uspoof_open(&status);
- * uspoof_setChecks(sc, USPOOF_INVISIBLE | USPOOF_MIXED_NUMBERS, &status);
- *
- * int32_t bitmask = uspoof_check2(sc, str, -1, NULL, &status);
- * UBool result = bitmask != 0;
- * // fails checks: 1 (status: U_ZERO_ERROR)
- * printf("fails checks: %d (status: %s)\n", result, u_errorName(status));
- * uspoof_close(sc);
- * \endcode
- *
- * Here is an example in C++ showing how to compute the restriction level of a string:
- *
- * \code{.cpp}
- * UErrorCode status = U_ZERO_ERROR;
- * UnicodeString str((UChar*) u"p\u0430ypal");  // with U+0430 CYRILLIC SMALL LETTER A
- *
- * // Get the default set of allowable characters:
- * UnicodeSet allowed;
- * allowed.addAll(*uspoof_getRecommendedUnicodeSet(&status));
- * allowed.addAll(*uspoof_getInclusionUnicodeSet(&status));
- *
- * LocalUSpoofCheckerPointer sc(uspoof_open(&status));
- * uspoof_setAllowedChars(sc.getAlias(), allowed.toUSet(), &status);
- * uspoof_setRestrictionLevel(sc.getAlias(), USPOOF_MODERATELY_RESTRICTIVE);
- * uspoof_setChecks(sc.getAlias(), USPOOF_RESTRICTION_LEVEL | USPOOF_AUX_INFO, &status);
- *
- * LocalUSpoofCheckResultPointer checkResult(uspoof_openCheckResult(&status));
- * int32_t bitmask = uspoof_check2UnicodeString(sc.getAlias(), str, checkResult.getAlias(), &status);
- *
- * URestrictionLevel restrictionLevel = uspoof_getCheckResultRestrictionLevel(checkResult.getAlias(), &status);
- * // Since USPOOF_AUX_INFO was enabled, the restriction level is also available in the upper bits of the bitmask:
- * assert((restrictionLevel & bitmask) == restrictionLevel);
- * // Restriction level: 0x50000000 (status: U_ZERO_ERROR)
- * printf("Restriction level: %#010x (status: %s)\n", restrictionLevel, u_errorName(status));
- * \endcode
- *
- * The code '0x50000000' corresponds to the restriction level USPOOF_MINIMALLY_RESTRICTIVE.  Since
- * USPOOF_MINIMALLY_RESTRICTIVE is weaker than USPOOF_MODERATELY_RESTRICTIVE, the string fails the check.
- *
- * <b>Note:</b> The Restriction Level is the most powerful of the checks. The full logic is documented in
- * <a href="http://unicode.org/reports/tr39/#Restriction_Level_Detection">UTS 39</a>, but the basic idea is that strings
- * are restricted to contain characters from only a single script, <em>except</em> that most scripts are allowed to have
- * Latin characters interspersed. Although the default restriction level is <code>HIGHLY_RESTRICTIVE</code>, it is
- * recommended that users set their restriction level to <code>MODERATELY_RESTRICTIVE</code>, which allows Latin mixed
- * with all other scripts except Cyrillic, Greek, and Cherokee, with which it is often confusable. For more details on
- * the levels, see UTS 39 or {@link URestrictionLevel}. The Restriction Level test is aware of the set of
- * allowed characters set in {@link uspoof_setAllowedChars}. Note that characters which have script code
- * COMMON or INHERITED, such as numbers and punctuation, are ignored when computing whether a string has multiple
- * scripts.
- *
- * <h2>Additional Information</h2>
- *
- * A <code>USpoofChecker</code> instance may be used repeatedly to perform checks on any number of identifiers.
- *
- * <b>Thread Safety:</b> The test functions for checking a single identifier, or for testing whether
- * two identifiers are possible confusable, are thread safe. They may called concurrently, from multiple threads,
- * using the same USpoofChecker instance.
- *
- * More generally, the standard ICU thread safety rules apply: functions that take a const USpoofChecker parameter are
- * thread safe. Those that take a non-const USpoofChecker are not thread safe..

- *
- * StringPrep API implements the StingPrep framework as described by RFC 3454.
- * StringPrep prepares Unicode strings for use in network protocols.
- * Profiles of StingPrep are set of rules and data according to with the
- * Unicode Strings are prepared. Each profiles contains tables which describe
- * how a code point should be treated. The tables are broadly classified into
- * <ul>
- *     <li> Unassigned Table: Contains code points that are unassigned 
- *          in the Unicode Version supported by StringPrep. Currently 
- *          RFC 3454 supports Unicode 3.2. </li>
- *     <li> Prohibited Table: Contains code points that are prohibited from
- *          the output of the StringPrep processing function. </li>
- *     <li> Mapping Table: Contains code points that are deleted from the output or case mapped. </li>
- * </ul>
- * 
- * The procedure for preparing Unicode strings:
- * <ol>
- *      <li> Map: For each character in the input, check if it has a mapping
- *           and, if so, replace it with its mapping. </li>
- *      <li> Normalize: Possibly normalize the result of step 1 using Unicode
- *           normalization. </li>
- *      <li> Prohibit: Check for any characters that are not allowed in the
- *        output.  If any are found, return an error.</li>
- *      <li> Check bidi: Possibly check for right-to-left characters, and if
- *           any are found, make sure that the whole string satisfies the
- *           requirements for bidirectional strings.  If the string does not
- *           satisfy the requirements for bidirectional strings, return an
- *           error.  </li>

-    TODO
- The following is a small list as to what is currently wrong/suggestions for
- ustdio.
-
- * Make sure that * in the scanf format specification works for all formats.
- * Each UFILE takes up at least 2KB.
-    Look into adding setvbuf() for configurable buffers.
- * This library does buffering. The OS should do this for us already. Check on
-    this, and remove it from this library, if this is the case. Double buffering
-    wastes a lot of time and space.
- * Test stdin and stdout with the u_f* functions
- * Testing should be done for reading and writing multi-byte encodings,
-    and make sure that a character that is contained across buffer boundries
-    works even for incomplete characters.
- * Make sure that the last character is flushed when the file/string is closed.
- * snprintf should follow the C99 standard for the return value, which is
-    return the number of characters (excluding the trailing '\0')
-    which would have been written to the destination string regardless
-    of available space. This is like pre-flighting.
- * Everything that uses %s should do what operator>> does for UnicodeString.
-    It should convert one byte at a time, and once a character is
-    converted then check to see if it's whitespace or in the scanset.
-    If it's whitespace or in the scanset, put all the bytes back (do nothing
-    for sprintf/sscanf).
- * If bad string data is encountered, make sure that the function fails
-    without memory leaks and the unconvertable characters are valid
-    substitution or are escaped characters.
- * u_fungetc() can't unget a character when it's at the beginning of the
-    internal conversion buffer. For example, read the buffer size # of
-    characters, and then ungetc to get the previous character that was
-    at the end of the last buffer.
- * u_fflush() and u_fclose should return an int32_t like C99 functions.
-    0 is returned if the operation was successful and EOF otherwise.
- * u_fsettransliterator does not support U_READ side of transliteration.
- * The format specifier should limit the size of a format or honor it in
-    order to prevent buffer overruns.  (e.g. %256.256d).
- * u_fread and u_fwrite don't exist. They're needed for reading and writing
-    data structures without any conversion.
- * u_file_read and u_file_write are used for writing strings. u_fgets and
-    u_fputs or u_fread and u_fwrite should be used to do this.
- * The width parameter for all scanf formats, including scanset, needs
-    better testing. This prevents buffer overflows.
- * Figure out what is suppose to happen when a codepage is changed midstream.
-    Maybe a flush or a rewind are good enough.
- * Make sure that a UFile opened with "rw" can be used after using
-    u_fflush with a u_frewind.
- * scanf(%i) should detect what type of number to use.
- * Add more testing of the alternate format, %#
- * Look at newline handling of fputs/puts
- * Think more about codeunit/codepoint error handling/support in %S,%s,%C,%c,%[]
- * Complete the file documentation with proper doxygen formatting.
-    See http://oss.software.ibm.com/pipermail/icu/2003-July/005647.html

- * \brief C API: Unicode stdio-like API
- *
- * <h2>Unicode stdio-like C API</h2>
- *
- * <p>This API provides an stdio-like API wrapper around ICU's other
- * formatting and parsing APIs. It is meant to ease the transition of adding
- * Unicode support to a preexisting applications using stdio. The following
- * is a small list of noticable differences between stdio and ICU I/O's
- * ustdio implementation.</p>
- *
- * <ul>
- * <li>Locale specific formatting and parsing is only done with file IO.</li>
- * <li>u_fstropen can be used to simulate file IO with strings.
- * This is similar to the iostream API, and it allows locale specific
- * formatting and parsing to be used.</li>
- * <li>This API provides uniform formatting and parsing behavior between
- * platforms (unlike the standard stdio implementations found on various
- * platforms).</li>
- * <li>This API is better suited for text data handling than binary data
- * handling when compared to the typical stdio implementation.</li>
- * <li>You can specify a Transliterator while using the file IO.</li>
- * <li>You can specify a file's codepage separately from the default
- * system codepage.</li>
- * </ul>
- *

-/**
- * \file
- * \brief C API: Unicode string handling functions
- *
- * These C API functions provide general Unicode string handling.
- *
- * Some functions are equivalent in name, signature, and behavior to the ANSI C <string.h>
- * functions. (For example, they do not check for bad arguments like NULL string pointers.)
- * In some cases, only the thread-safe variant of such a function is implemented here
- * (see u_strtok_r()).
- *
- * Other functions provide more Unicode-specific functionality like locale-specific
- * upper/lower-casing and string comparison in code point order.
- *
- * ICU uses 16-bit Unicode (UTF-16) in the form of arrays of UChar code units.
- * UTF-16 encodes each Unicode code point with either one or two UChar code units.
- * (This is the default form of Unicode, and a forward-compatible extension of the original,
- * fixed-width form that was known as UCS-2. UTF-16 superseded UCS-2 with Unicode 2.0
- * in 1996.)
- *
- * Some APIs accept a 32-bit UChar32 value for a single code point.
- *
- * ICU also handles 16-bit Unicode text with unpaired surrogates.
- * Such text is not well-formed UTF-16.
- * Code-point-related functions treat unpaired surrogates as surrogate code points,
- * i.e., as separate units.
- *
- * Although UTF-16 is a variable-width encoding form (like some legacy multi-byte encodings),
- * it is much more efficient even for random access because the code unit values
- * for single-unit characters vs. lead units vs. trail units are completely disjoint.
- * This means that it is easy to determine character (code point) boundaries from
- * random offsets in the string.
- *
- * Unicode (UTF-16) string processing is optimized for the single-unit case.
- * Although it is important to support supplementary characters
- * (which use pairs of lead/trail code units called "surrogates"),
- * their occurrence is rare. Almost all characters in modern use require only
- * a single UChar code unit (i.e., their code point values are <=0xffff).
- *
- * For more details see the User Guide Strings chapter (http://icu-project.org/userguide/strings.html).
- * For a discussion of the handling of unpaired surrogates see also
- * Jitterbug 2145 and its icu mailing list proposal on 2002-sep-18.

- * Unescape a string of characters and write the resulting
- * Unicode characters to the destination buffer.  The following escape
- * sequences are recognized:
- *
- * \\uhhhh       4 hex digits; h in [0-9A-Fa-f]
- * \\Uhhhhhhhh   8 hex digits
- * \\xhh         1-2 hex digits
- * \\x{h...}     1-8 hex digits
- * \\ooo         1-3 octal digits; o in [0-7]
- * \\cX          control-X; X is masked with 0x1F
- *
- * as well as the standard ANSI C escapes:
- *
- * \\a => U+0007, \\b => U+0008, \\t => U+0009, \\n => U+000A,
- * \\v => U+000B, \\f => U+000C, \\r => U+000D, \\e => U+001B,
- * \\&quot; => U+0022, \\' => U+0027, \\? => U+003F, \\\\ => U+005C
- *
- * Anything else following a backslash is generically escaped.  For
- * example, "[a\\-z]" returns "[a-z]".
- *
- * If an escape sequence is ill-formed, this method returns an empty
- * string.  An example of an ill-formed sequence is "\\u" followed by
- * fewer than 4 hex digits.
- *
- * The above characters are recognized in the compiler's codepage,
- * that is, they are coded as 'u', '\\', etc.  Characters that are
- * not parts of escape sequences are converted using u_charsToUChars().
- *

- * return value will still be valid.  On error, an empty string is
- * stored here (if possible).

-/**
- * Convert a UTF-8 string to UTF-16.
- *
- * Same as u_strFromUTF8() except that this function is designed to be very fast,
- * which it achieves by being lenient about malformed UTF-8 sequences.
- * This function is intended for use in environments where UTF-8 text is
- * expected to be well-formed.
- *
- * Its semantics are:
- * - Well-formed UTF-8 text is correctly converted to well-formed UTF-16 text.
- * - The function will not read beyond the input string, nor write beyond
- *   the destCapacity.
- * - Malformed UTF-8 results in "garbage" 16-bit Unicode strings which may not
- *   be well-formed UTF-16.
- *   The function will resynchronize to valid code point boundaries
- *   within a small number of code points after an illegal sequence.
- * - Non-shortest forms are not detected and will result in "spoofing" output.
- *
- * For further performance improvement, if srcLength is given (>=0),
- * then it must be destCapacity>=srcLength.
- *
- * There is no inverse u_strToUTF8Lenient() function because there is practically
- * no performance gain from not checking that a UTF-16 string is well-formed.
- *
- * @param dest          A buffer for the result string. The result will be zero-terminated if

- *                      Unlike for other ICU functions, if srcLength>=0 then it
- *                      must be destCapacity>=srcLength.
- * @param pDestLength   A pointer to receive the number of units written to the destination. If

-/**
- * \file
- * \brief C API: Abstract Unicode Text API
- *
- * The Text Access API provides a means to allow text that is stored in alternative
- * formats to work with ICU services.  ICU normally operates on text that is
- * stored in UTF-16 format, in (UChar *) arrays for the C APIs or as type
- * UnicodeString for C++ APIs.
- *
- * ICU Text Access allows other formats, such as UTF-8 or non-contiguous
- * UTF-16 strings, to be placed in a UText wrapper and then passed to ICU services.
- *
- * There are three general classes of usage for UText:
- *
- *     Application Level Use.  This is the simplest usage - applications would
- *     use one of the utext_open() functions on their input text, and pass
- *     the resulting UText to the desired ICU service.
- *
- *     Second is usage in ICU Services, such as break iteration, that will need to
- *     operate on input presented to them as a UText.  These implementations
- *     will need to use the iteration and related UText functions to gain
- *     access to the actual text.
- *
- *     The third class of UText users are "text providers."  These are the
- *     UText implementations for the various text storage formats.  An application
- *     or system with a unique text storage format can implement a set of
- *     UText provider functions for that format, which will then allow
- *     ICU services to operate on that format.
- *
- *
- * <em>Iterating over text</em>
- *
- * Here is sample code for a forward iteration over the contents of a UText
- *
- * \code
- *    UChar32  c;
- *    UText    *ut = whatever();
- *
- *    for (c=utext_next32From(ut, 0); c>=0; c=utext_next32(ut)) {
- *       // do whatever with the codepoint c here.
- *    }
- * \endcode
- *
- * And here is similar code to iterate in the reverse direction, from the end
- * of the text towards the beginning.
- *
- * \code
- *    UChar32  c;
- *    UText    *ut = whatever();
- *    int      textLength = utext_nativeLength(ut);
- *    for (c=utext_previous32From(ut, textLength); c>=0; c=utext_previous32(ut)) {
- *       // do whatever with the codepoint c here.
- *    }
- * \endcode
- *
- * <em>Characters and Indexing</em>
- *
- * Indexing into text by UText functions is nearly always in terms of the native
- * indexing of the underlying text storage.  The storage format could be UTF-8
- * or UTF-32, for example.  When coding to the UText access API, no assumptions
- * can be made regarding the size of characters, or how far an index
- * may move when iterating between characters.
- *
- * All indices supplied to UText functions are pinned to the length of the
- * text.  An out-of-bounds index is not considered to be an error, but is
- * adjusted to be in the range  0 <= index <= length of input text.
- *
- *
- * When an index position is returned from a UText function, it will be
- * a native index to the underlying text.  In the case of multi-unit characters,
- * it will  always refer to the first position of the character,
- * never to the interior.  This is essentially the same thing as saying that
- * a returned index will always point to a boundary between characters.
- *
- * When a native index is supplied to a UText function, all indices that
- * refer to any part of a multi-unit character representation are considered
- * to be equivalent.  In the case of multi-unit characters, an incoming index
- * will be logically normalized to refer to the start of the character.
- * 
- * It is possible to test whether a native index is on a code point boundary
- * by doing a utext_setNativeIndex() followed by a utext_getNativeIndex().
- * If the index is returned unchanged, it was on a code point boundary.  If
- * an adjusted index is returned, the original index referred to the
- * interior of a character.
- *
- * <em>Conventions for calling UText functions</em>
- *
- * Most UText access functions have as their first parameter a (UText *) pointer,
- * which specifies the UText to be used.  Unless otherwise noted, the
- * pointer must refer to a valid, open UText.  Attempting to
- * use a closed UText or passing a NULL pointer is a programming error and
- * will produce undefined results or NULL pointer exceptions.
- * 
- * The UText_Open family of functions can either open an existing (closed)
- * UText, or heap allocate a new UText.  Here is sample code for creating
- * a stack-allocated UText.
- *
- * \code
- *    char     *s = whatever();  // A utf-8 string 
- *    U_ErrorCode status = U_ZERO_ERROR;
- *    UText    ut = UTEXT_INITIALIZER;
- *    utext_openUTF8(ut, s, -1, &status);
- *    if (U_FAILURE(status)) {
- *        // error handling
- *    } else {
- *        // work with the UText
- *    }
- * \endcode
- *
- * Any existing UText passed to an open function _must_ have been initialized, 
- * either by the UTEXT_INITIALIZER, or by having been originally heap-allocated
- * by an open function.  Passing NULL will cause the open function to
- * heap-allocate and fully initialize a new UText.

-/**
- * \file
- * \brief C API: Code point macros
- *
- * This file defines macros for checking whether a code point is
- * a surrogate or a non-character etc.
- *
- * If U_NO_DEFAULT_INCLUDE_UTF_HEADERS is 0 then utf.h is included by utypes.h
- * and itself includes utf8.h and utf16.h after some
- * common definitions.
- * If U_NO_DEFAULT_INCLUDE_UTF_HEADERS is 1 then each of these headers must be
- * included explicitly if their definitions are used.
- *
- * utf8.h and utf16.h define macros for efficiently getting code points
- * in and out of UTF-8/16 strings.
- * utf16.h macros have "U16_" prefixes.
- * utf8.h defines similar macros with "U8_" prefixes for UTF-8 string handling.
- *
- * ICU mostly processes 16-bit Unicode strings.
- * Most of the time, such strings are well-formed UTF-16.
- * Single, unpaired surrogates must be handled as well, and are treated in ICU
- * like regular code points where possible.
- * (Pairs of surrogate code points are indistinguishable from supplementary
- * code points encoded as pairs of supplementary code units.)
- *
- * In fact, almost all Unicode code points in normal text (>99%)
- * are on the BMP (<=U+ffff) and even <=U+d7ff.
- * ICU functions handle supplementary code points (U+10000..U+10ffff)
- * but are optimized for the much more frequently occurring BMP code points.
- *
- * umachine.h defines UChar to be an unsigned 16-bit integer.
- * Since ICU 59, ICU uses char16_t in C++, UChar only in C,
- * and defines UChar=char16_t by default. See the UChar API docs for details.
- *
- * UChar32 is defined to be a signed 32-bit integer (int32_t), large enough for a 21-bit
- * Unicode code point (Unicode scalar value, 0..0x10ffff) and U_SENTINEL (-1).
- * Before ICU 2.4, the definition of UChar32 was similarly platform-dependent as
- * the definition of UChar. For details see the documentation for UChar32 itself.
- *
- * utf.h defines a small number of C macros for single Unicode code points.
- * These are simple checks for surrogates and non-characters.
- * For actual Unicode character properties see uchar.h.
- *
- * By default, string operations must be done with error checking in case
- * a string is not well-formed UTF-16 or UTF-8.
- *
- * The U16_ macros detect if a surrogate code unit is unpaired
- * (lead unit without trail unit or vice versa) and just return the unit itself
- * as the code point.
- *
- * The U8_ macros detect illegal byte sequences and return a negative value.
- * Starting with ICU 60, the observable length of a single illegal byte sequence
- * skipped by one of these macros follows the Unicode 6+ recommendation
- * which is consistent with the W3C Encoding Standard.
- *
- * There are ..._OR_FFFD versions of both U16_ and U8_ macros
- * that return U+FFFD for illegal code unit sequences.
- *
- * The regular "safe" macros require that the initial, passed-in string index
- * is within bounds. They only check the index when they read more than one
- * code unit. This is usually done with code similar to the following loop:
- * <pre>while(i<length) {
- *   U16_NEXT(s, i, length, c);
- *   // use c
- * }</pre>
- *
- * When it is safe to assume that text is well-formed UTF-16
- * (does not contain single, unpaired surrogates), then one can use
- * U16_..._UNSAFE macros.
- * These do not check for proper code unit sequences or truncated text and may
- * yield wrong results or even cause a crash if they are used with "malformed"
- * text.
- * In practice, U16_..._UNSAFE macros will produce slightly less code but
- * should not be faster because the processing is only different when a
- * surrogate code unit is detected, which will be rare.
- *
- * Similarly for UTF-8, there are "safe" macros without a suffix,
- * and U8_..._UNSAFE versions.
- * The performance differences are much larger here because UTF-8 provides so
- * many opportunities for malformed sequences.
- * The unsafe UTF-8 macros are entirely implemented inside the macro definitions
- * and are fast, while the safe UTF-8 macros call functions for some complicated cases.
- *
- * Unlike with UTF-16, malformed sequences cannot be expressed with distinct
- * code point values (0..U+10ffff). They are indicated with negative values instead.
- *
- * For more information see the ICU User Guide Strings chapter
- * (http://userguide.icu-project.org/strings).
- *
- * <em>Usage:</em>
- * ICU coding guidelines for if() statements should be followed when using these macros.
- * Compound statements (curly braces {}) must be used  for if-else-while... 
- * bodies and all macro statements should be terminated with semicolon.

- * \file
- * \brief C API: Deprecated macros for Unicode string handling
- *
- * The macros in utf_old.h are all deprecated and their use discouraged.
- * Some of the design principles behind the set of UTF macros
- * have changed or proved impractical.
- * Almost all of the old "UTF macros" are at least renamed.
- * If you are looking for a new equivalent to an old macro, please see the
- * comment at the old one.
- *
- * Brief summary of reasons for deprecation:
- * - Switch on UTF_SIZE (selection of UTF-8/16/32 default string processing)
- *   was impractical.
- * - Switch on UTF_SAFE etc. (selection of unsafe/safe/strict default string processing)
- *   was of little use and impractical.
- * - Whole classes of macros became obsolete outside of the UTF_SIZE/UTF_SAFE
- *   selection framework: UTF32_ macros (all trivial)
- *   and UTF_ default and intermediate macros (all aliases).
- * - The selection framework also caused many macro aliases.
- * - Change in Unicode standard: "irregular" sequences (3.0) became illegal (3.2).
- * - Change of language in Unicode standard:
- *   Growing distinction between internal x-bit Unicode strings and external UTF-x
- *   forms, with the former more lenient.
- *   Suggests renaming of UTF16_ macros to U16_.
- * - The prefix "UTF_" without a width number confused some users.
- * - "Safe" append macros needed the addition of an error indicator output.
- * - "Safe" UTF-8 macros used legitimate (if rarely used) code point values
- *   to indicate error conditions.
- * - The use of the "_CHAR" infix for code point operations confused some users.
- *
- * More details:
- *
- * Until ICU 2.2, utf.h theoretically allowed to choose among UTF-8/16/32
- * for string processing, and among unsafe/safe/strict default macros for that.
- *
- * It proved nearly impossible to write non-trivial, high-performance code
- * that is UTF-generic.
- * Unsafe default macros would be dangerous for default string processing,
- * and the main reason for the "strict" versions disappeared:
- * Between Unicode 3.0 and 3.2 all "irregular" UTF-8 sequences became illegal.
- * The only other conditions that "strict" checked for were non-characters,
- * which are valid during processing. Only during text input/output should they
- * be checked, and at that time other well-formedness checks may be
- * necessary or useful as well.
- * This can still be done by using U16_NEXT and U_IS_UNICODE_NONCHAR
- * or U_IS_UNICODE_CHAR.
- *
- * The old UTF8_..._SAFE macros also used some normal Unicode code points
- * to indicate malformed sequences.
- * The new UTF8_ macros without suffix use negative values instead.
- *
- * The entire contents of utf32.h was moved here without replacement
- * because all those macros were trivial and
- * were meaningful only in the framework of choosing the UTF size.
- *
- * See Jitterbug 2150 and its discussion on the ICU mailing list
- * in September 2002.
- *
- * <hr>
- *
- * <em>Obsolete part</em> of pre-ICU 2.4 utf.h file documentation:
- *
- * <p>The original concept for these files was for ICU to allow
- * in principle to set which UTF (UTF-8/16/32) is used internally
- * by defining UTF_SIZE to either 8, 16, or 32. utf.h would then define the UChar type
- * accordingly. UTF-16 was the default.</p>
- *
- * <p>This concept has been abandoned.
- * A lot of the ICU source code assumes UChar strings are in UTF-16.
- * This is especially true for low-level code like
- * conversion, normalization, and collation.
- * The utf.h header enforces the default of UTF-16.
- * The UTF-8 and UTF-32 macros remain for now for completeness and backward compatibility.</p>
- *
- * <p>Accordingly, utf.h defines UChar to be an unsigned 16-bit integer. If this matches wchar_t, then
- * UChar is defined to be exactly wchar_t, otherwise uint16_t.</p>
- *
- * <p>UChar32 is defined to be a signed 32-bit integer (int32_t), large enough for a 21-bit
- * Unicode code point (Unicode scalar value, 0..0x10ffff).
- * Before ICU 2.4, the definition of UChar32 was similarly platform-dependent as
- * the definition of UChar. For details see the documentation for UChar32 itself.</p>
- *
- * <p>utf.h also defines a number of C macros for handling single Unicode code points and
- * for using UTF Unicode strings. It includes utf8.h, utf16.h, and utf32.h for the actual
- * implementations of those macros and then aliases one set of them (for UTF-16) for general use.
- * The UTF-specific macros have the UTF size in the macro name prefixes (UTF16_...), while
- * the general alias macros always begin with UTF_...</p>
- *
- * <p>Many string operations can be done with or without error checking.
- * Where such a distinction is useful, there are two versions of the macros, "unsafe" and "safe"
- * ones with ..._UNSAFE and ..._SAFE suffixes. The unsafe macros are fast but may cause
- * program failures if the strings are not well-formed. The safe macros have an additional, boolean
- * parameter "strict". If strict is FALSE, then only illegal sequences are detected.
- * Otherwise, irregular sequences and non-characters are detected as well (like single surrogates).
- * Safe macros return special error code points for illegal/irregular sequences:
- * Typically, U+ffff, or values that would result in a code unit sequence of the same length
- * as the erroneous input sequence.<br>
- * Note that _UNSAFE macros have fewer parameters: They do not have the strictness parameter, and
- * they do not have start/length parameters for boundary checking.</p>
- *
- * <p>Here, the macros are aliased in two steps:
- * In the first step, the UTF-specific macros with UTF16_ prefix and _UNSAFE and _SAFE suffixes are
- * aliased according to the UTF_SIZE to macros with UTF_ prefix and the same suffixes and signatures.
- * Then, in a second step, the default, general alias macros are set to use either the unsafe or
- * the safe/not strict (default) or the safe/strict macro;
- * these general macros do not have a strictness parameter.</p>
- *
- * <p>It is possible to change the default choice for the general alias macros to be unsafe, safe/not strict or safe/strict.
- * The default is safe/not strict. It is not recommended to select the unsafe macros as the basis for
- * Unicode string handling in ICU! To select this, define UTF_SAFE, UTF_STRICT, or UTF_UNSAFE.</p>
- *
- * <p>For general use, one should use the default, general macros with UTF_ prefix and no _SAFE/_UNSAFE suffix.
- * Only in some cases it may be necessary to control the choice of macro directly and use a less generic alias.
- * For example, if it can be assumed that a string is well-formed and the index will stay within the bounds,
- * then the _UNSAFE version may be used.
- * If a UTF-8 string is to be processed, then the macros with UTF8_ prefixes need to be used.</p>
- *
- * <hr>
- *
- * Deprecated ICU 2.4. Use the macros in utf.h, utf16.h, utf8.h instead.

-/** 
- * \file
- * \brief C API: Universal Time Scale
- *
- * There are quite a few different conventions for binary datetime, depending on different
- * platforms and protocols. Some of these have severe drawbacks. For example, people using
- * Unix time (seconds since Jan 1, 1970) think that they are safe until near the year 2038.
- * But cases can and do arise where arithmetic manipulations causes serious problems. Consider
- * the computation of the average of two datetimes, for example: if one calculates them with
- * <code>averageTime = (time1 + time2)/2</code>, there will be overflow even with dates
- * around the present. Moreover, even if these problems don't occur, there is the issue of
- * conversion back and forth between different systems.
- *
- * <p>
- * Binary datetimes differ in a number of ways: the datatype, the unit,
- * and the epoch (origin). We'll refer to these as time scales. For example:
- *
- * <table border="1" cellspacing="0" cellpadding="4">

- * <p>
- * These functions implement a universal time scale which can be used as a 'pivot',
- * and provide conversion functions to and from all other major time scales.
- * This datetimes to be converted to the pivot time, safely manipulated,
- * and converted back to any other datetime time scale.
- *
- *<p>
- * So what to use for this pivot? Java time has plenty of range, but cannot represent
- * .NET <code>System.DateTime</code> values without severe loss of precision. ICU4C time addresses this by using a
- * <code>double</code> that is otherwise equivalent to the Java time. However, there are disadvantages
- * with <code>doubles</code>. They provide for much more graceful degradation in arithmetic operations.
- * But they only have 53 bits of accuracy, which means that they will lose precision when
- * converting back and forth to ticks. What would really be nice would be a
- * <code>long double</code> (80 bits -- 64 bit mantissa), but that is not supported on most systems.
- *
- *<p>
- * The Unix extended time uses a structure with two components: time in seconds and a
- * fractional field (microseconds). However, this is clumsy, slow, and
- * prone to error (you always have to keep track of overflow and underflow in the
- * fractional field). <code>BigDecimal</code> would allow for arbitrary precision and arbitrary range,
- * but we do not want to use this as the normal type, because it is slow and does not
- * have a fixed size.
- *
- *<p>
- * Because of these issues, we ended up concluding that the .NET framework's
- * <code>System.DateTime</code> would be the best pivot. However, we use the full range
- * allowed by the datatype, allowing for datetimes back to 29,000 BC and up to 29,000 AD.
- * This time scale is very fine grained, does not lose precision, and covers a range that
- * will meet almost all requirements. It will not handle the range that Java times do,
- * but frankly, being able to handle dates before 29,000 BC or after 29,000 AD is of very limited interest.

-/*
- *
- * ICU trace format string syntax
- *
- * Format Strings are passed to UTraceData functions, and define the
- * number and types of the trace data being passed on each call.
- *
- * The UTraceData function, which is supplied by the application,
- * not by ICU, can either forward the trace data (passed via
- * varargs) and the format string back to ICU for formatting into
- * a displayable string, or it can interpret the format itself,
- * and do as it wishes with the trace data.
- *
- *
- * Goals for the format string
- * - basic data output
- * - easy to use for trace programmer
- * - sufficient provision for data types for trace output readability
- * - well-defined types and binary portable APIs
- *
- * Non-goals
- * - printf compatibility
- * - fancy formatting
- * - argument reordering and other internationalization features
- *
- * ICU trace format strings contain plain text with argument inserts,
- * much like standard printf format strings.
- * Each insert begins with a '%', then optionally contains a 'v',
- * then exactly one type character.
- * Two '%' in a row represent a '%' instead of an insert.
- * The trace format strings need not have \n at the end.
- *
- *
- * Types
- * -----
- *
- * Type characters:
- * - c A char character in the default codepage.
- * - s A NUL-terminated char * string in the default codepage.
- * - S A UChar * string.  Requires two params, (ptr, length).  Length=-1 for nul term.
- * - b A byte (8-bit integer).
- * - h A 16-bit integer.  Also a 16 bit Unicode code unit.
- * - d A 32-bit integer.  Also a 20 bit Unicode code point value. 
- * - l A 64-bit integer.
- * - p A data pointer.
- *
- * Vectors
- * -------
- *
- * If the 'v' is not specified, then one item of the specified type
- * is passed in.
- * If the 'v' (for "vector") is specified, then a vector of items of the
- * specified type is passed in, via a pointer to the first item
- * and an int32_t value for the length of the vector.
- * Length==-1 means zero or NUL termination.  Works for vectors of all types.
- *
- * Note:  %vS is a vector of (UChar *) strings.  The strings must
- *        be nul terminated as there is no way to provide a
- *        separate length parameter for each string.  The length
- *        parameter (required for all vectors) is the number of
- *        strings, not the length of the strings.
- *
- * Examples
- * --------
- *
- * These examples show the parameters that will be passed to an application's
- *   UTraceData() function for various formats.
- *
- * - the precise formatting is up to the application!
- * - the examples use type casts for arguments only to _show_ the types of
- *   arguments without needing variable declarations in the examples;
- *   the type casts will not be necessary in actual code
- *
- * UTraceDataFunc(context, fnNumber, level,
- *              "There is a character %c in the string %s.",   // Format String 
- *              (char)c, (const char *)s);                     // varargs parameters
- * ->   There is a character 0x42 'B' in the string "Bravo".
- *
- * UTraceDataFunc(context, fnNumber, level,
- *              "Vector of bytes %vb vector of chars %vc",
- *              (const uint8_t *)bytes, (int32_t)bytesLength,
- *              (const char *)chars, (int32_t)charsLength);
- * ->  Vector of bytes
- *      42 63 64 3f [4]
- *     vector of chars
- *      "Bcd?"[4]
- *
- * UTraceDataFunc(context, fnNumber, level,
- *              "An int32_t %d and a whole bunch of them %vd",
- *              (int32_t)-5, (const int32_t *)ints, (int32_t)intsLength);

-/**

- * \brief C API: Transliterator
- *
- * <h2> Transliteration </h2>
- * The data structures and functions described in this header provide
- * transliteration services.  Transliteration services are implemented
- * as C++ classes.  The comments and documentation in this header
- * assume the reader is familiar with the C++ headers translit.h and
- * associated documentation.
- *
- * A significant but incomplete subset of the C++ transliteration
- * services are available to C code through this header.  In order to
- * access more complex transliteration services, refer to the C++
- * headers and documentation.
- *
- * There are two sets of functions for working with transliterator IDs:
- *
- * An old, deprecated set uses char * IDs, which works for true and pure
- * identifiers that these APIs were designed for,
- * for example "Cyrillic-Latin".
- * It does not work when the ID contains filters ("[:Script=Cyrl:]")
- * or even a complete set of rules because then the ID string contains more
- * than just "invariant" characters (see utypes.h).
- *
- * A new set of functions replaces the old ones and uses UChar * IDs,
- * paralleling the UnicodeString IDs in the C++ API. (New in ICU 2.8.)

-
-    <p>Today's software market is a global one in which it is desirable to
-    develop and maintain one application (single source/single binary) that
-    supports a wide variety of languages. The International Components for
-    Unicode (ICU) libraries provide robust and full-featured Unicode services on
-    a wide variety of platforms to help this design goal. The ICU libraries
-    provide support for:</p>
-
-    <ul>
-      <li>The latest version of the Unicode standard</li>
-
-      <li>Character set conversions with support for over 220 codepages</li>
-
-      <li>Locale data for more than 300 locales</li>
-
-      <li>Language sensitive text collation (sorting) and searching based on the
-      Unicode Collation Algorithm (=ISO 14651)</li>
-
-      <li>Regular expression matching and Unicode sets</li>
-
-      <li>Transformations for normalization, upper/lowercase, script
-      transliterations (50+ pairs)</li>
-
-      <li>Resource bundles for storing and accessing localized information</li>
-
-      <li>Date/Number/Message formatting and parsing of culture specific
-      input/output formats</li>
-
-      <li>Calendar specific date and time manipulation</li>
-
-      <li>Text boundary analysis for finding characters, word and sentence
-      boundaries</li>
-    </ul>
-
-    <p>ICU has a sister project ICU4J that extends the internationalization
-    capabilities of Java to a level similar to ICU. The ICU C/C++ project is also
-    called ICU4C when a distinction is necessary.</p>

-    <h2><a name="Download" href="#Download" id="Download">How To Download the
-    Source Code</a></h2>
-
-    <p>There are two ways to download ICU releases:</p>
-
-    <ul>
-      <li><strong>Official Release Snapshot:</strong><br />
-       If you want to use ICU (as opposed to developing it), you should download
-      an official packaged version of the ICU source code. These versions are
-      tested more thoroughly than day-to-day development builds of the system,
-      and they are packaged in zip and tar files for convenient download. These
-      packaged files can be found at <a href=
-      "http://site.icu-project.org/download">http://site.icu-project.org/download</a>.<br />
-       The packaged snapshots are named <strong>icu-nnnn.zip</strong> or
-      <strong>icu-nnnn.tgz</strong>, where nnnn is the version number. The .zip
-      file is used for Windows platforms, while the .tgz file is preferred on
-      most other platforms.<br />
-       Please unzip this file. </li>
-
-      <li><strong>GitHub Source Repository:</strong><br />
-       If you are interested in developing features, patches, or bug fixes for
-      ICU, you should probably be working with the latest version of the ICU
-      source code. You will need to clone and checkout the code from our GitHub repository to
-      ensure that you have the most recent version of all of the files. See our
-      <a href="http://site.icu-project.org/repository">source
-      repository</a> for details.</li>
-    </ul>
-
-    <h2><a name="SourceCode" href="#SourceCode" id="SourceCode">ICU Source Code

-
-    <p>In the descriptions below, <strong><i>&lt;ICU&gt;</i></strong> is the full

-    "http://userguide.icu-project.org/design">ICU Architectural
-    Design</a> section of the User's Guide to see which libraries you need for
-    your software product. You need at least the data (<code>[lib]icudt</code>)
-    and the common (<code>[lib]icuuc</code>) libraries in order to use ICU.</p>

-      <li><b>UnicodeString constructors:</b> The UnicodeString class has
-        several single-argument constructors that are not marked "explicit"
-        for historical reasons.
-        This can lead to inadvertent construction of a <code>UnicodeString</code>
-        with a single character by using an integer,
-        and it can lead to inadvertent dependency on the conversion framework
-        by using a C string literal.<br />
-        Beginning with ICU 49, you should do the following:
-        <ul>
-          <li>Consider marking the from-<code>UChar</code>
-            and from-<code>UChar32</code> constructors explicit via
-            <code>-DUNISTR_FROM_CHAR_EXPLICIT=explicit</code> or similar.</li>
-          <li>Consider marking the from-<code>const char*</code> and
-            from-<code>const UChar*</code> constructors explicit via
-            <code>-DUNISTR_FROM_STRING_EXPLICIT=explicit</code> or similar.</li>
-        </ul>
-        Note: The ICU test suites cannot be compiled with these settings.
-      </li>
-      <li><b>utf.h, utf8.h, utf16.h, utf_old.h:</b>
-        By default, utypes.h (and thus almost every public ICU header)
-        includes all of these header files.
-        Often, none of them are needed, or only one or two of them.
-        All of utf_old.h is deprecated or obsolete.<br />
-        Beginning with ICU 49,
-        you should define <code>U_NO_DEFAULT_INCLUDE_UTF_HEADERS</code> to 1
-        (via -D or uconfig.h, as above)
-        and include those header files explicitly that you actually need.<br />
-        Note: The ICU test suites cannot be compiled with this setting.</li>
-      <li><b>utf_old.h:</b>
-        All of utf_old.h is deprecated or obsolete.<br />
-        Beginning with ICU 60,
-        you should define <code>U_HIDE_OBSOLETE_UTF_OLD_H</code> to 1
-        (via -D or uconfig.h, as above).
-        Use of any of these macros should be replaced as noted
-        in the comments for the obsolete macro.<br />
-        Note: The ICU test suites <i>can</i> be compiled with this setting.</li>
-      <li><b>.dat file:</b> By default, the ICU data is built into
-        a shared library (DLL). This is convenient because it requires no
-        install-time or runtime configuration,
-        but the library is platform-specific and cannot be modified.
-        A .dat package file makes the opposite trade-off:
-        Platform-portable (except for endianness and charset family, which
-        can be changed with the icupkg tool)
-        and modifiable (also with the icupkg tool).
-        If a path is set, then single data files (e.g., .res files)
-        can be copied to that location to provide new locale data
-        or conversion tables etc.<br />
-        The only drawback with a .dat package file is that the application
-        needs to provide ICU with the file system path to the package file
-        (e.g., by calling <code>u_setDataDirectory()</code>)
-        or with a pointer to the data (<code>udata_setCommonData()</code>)
-        before other ICU API calls.
-        This is usually easy if ICU is used from an application where
-        <code>main()</code> takes care of such initialization.
-        It may be hard if ICU is shipped with
-        another shared library (such as the Xerces-C++ XML parser)
-        which does not control <code>main()</code>.<br />
-        See the <a href="http://userguide.icu-project.org/icudata">User Guide ICU Data</a>
-        chapter for more details.<br />
-        If possible, we recommend building the .dat package.
-        Specify <code>--with-data-packaging=archive</code>
-        on the configure command line, as in<br />
-        <code>runConfigureICU Linux --with-data-packaging=archive</code><br />
-        (Read the configure script's output for further instructions.
-        On Windows, the Visual Studio build generates both the .dat package
-        and the data DLL.)<br />
-        Be sure to install and use the tiny stubdata library
-        rather than the large data DLL.</li>
-      <li><b>Static libraries:</b> It may make sense to build the ICU code
-        into static libraries (.a) rather than shared libraries (.so/.dll).
-        Static linking reduces the overall size of the binary by removing
-        code that is never called.<br />
-        Example configure command line:<br />
-        <code>runConfigureICU Linux --enable-static --disable-shared</code></li>
-      <li><b>Out-of-source build:</b> It is usually desirable to keep the ICU
-        source file tree clean and have build output files written to
-        a different location. This is called an "out-of-source build".
-        Simply invoke the configure script from the target location:
-<pre>~/icu$ git clone export https://github.com/unicode-org/icu.git
-~/icu$ mkdir icu4c-build
-~/icu$ cd icu4c-build
-~/icu/icu4c-build$ ../icu/icu4c/source/runConfigureICU Linux
-~/icu/icu4c-build$ make check</pre><br/>
-        (Note: this example shows a relative path to
-         <code>runConfigureICU</code>. If you experience difficulty,
-         try using an absolute path to <code>runConfigureICU</code>
-         instead.)
-      </li>
-    </ul>
-    <h4>ICU as a System-Level Library</h4>
-    <p>If ICU is installed as a system-level library, there are further
-      opportunities and restrictions to consider.
-      For details, see the <em>Using ICU as an Operating System Level Library</em>
-      section of the <a href="http://userguide.icu-project.org/design">User Guide ICU Architectural Design</a> chapter.</p>
-    <ul>
-      <li><b>Data path:</b> For a system-level library, it is best to load
-        ICU data from the .dat package file because the file system path
-        to the .dat package file can be hardcoded. ICU will automatically set
-        the path to the final install location using U_ICU_DATA_DEFAULT_DIR.
-        Alternatively, you can set <code>-DICU_DATA_DIR=/path/to/icu/data</code>
-        when building the ICU code. (Used by source/common/putil.c.)<br/>
-        Consider also setting <code>-DICU_NO_USER_DATA_OVERRIDE</code>
-        if you do not want the "ICU_DATA" environment variable to be used.
-        (An application can still override the data path via
-        <code>u_setDataDirectory()</code> or
-        <code>udata_setCommonData()</code>.</li>
-      <li><b>Hide draft API:</b> API marked with <code>@draft</code>
-        is new and not yet stable. Applications must not rely on unstable
-        APIs from a system-level library.
-        Define <code>U_HIDE_DRAFT_API</code>, <code>U_HIDE_INTERNAL_API</code>
-        and <code>U_HIDE_SYSTEM_API</code>
-        by modifying unicode/utypes.h before installing it.</li>
-      <li><b>Only C APIs:</b> Applications must not rely on C++ APIs from a
-        system-level library because binary C++ compatibility
-        across library and compiler versions is very hard to achieve.
-        Most ICU C++ APIs are in header files that contain a comment with
-        <code>\brief C++ API</code>.
-        Consider not installing these header files, or define <code>U_SHOW_CPLUSPLUS_API</code>
-        to be <code>0</code> by modifying unicode/utypes.h before installing it.</li>
-      <li><b>Disable renaming:</b> By default, ICU library entry point names
-        have an ICU version suffix. Turn this off for a system-level installation,
-        to enable upgrading ICU without breaking applications. For example:<br />
-        <code>runConfigureICU Linux --disable-renaming</code><br />
-        The public header files from this configuration must be installed
-        for applications to include and get the correct entry point names.</li>
-    </ul>
-
-    <h3><a name="UserConfig" href="#UserConfig" id="UserConfig">User-Configurable Settings</a></h3>
-    <p>ICU4C can be customized via a number of user-configurable settings.
-    Many of them are controlled by preprocessor macros which are
-    defined in the <code>source/common/unicode/uconfig.h</code> header file.
-    Some turn off parts of ICU, for example conversion or collation,
-    trading off a smaller library for reduced functionality.
-    Other settings are recommended (see previous section)
-    but their default values are set for better source code compatibility.</p>
-
-    <p>In order to change such user-configurable settings, you can
-    either modify the <code>uconfig.h</code> header file by adding
-    a specific <code>#define ...</code> for one or more of the macros
-    before they are first tested,
-    or set the compiler's preprocessor flags (<code>CPPFLAGS</code>) to include
-    an equivalent <code>-D</code> macro definition.</p>

-    <p>Building International Components for Unicode requires:</p>
-
-    <ul>
-      <li>Microsoft Windows</li>
-
-      <li>Microsoft Visual C++ (part of <a href="https://www.visualstudio.com/">Visual Studio</a>) (from either Visual Studio 2015 or Visual Studio 2017)</li>
-      
-      <li><i><b>Optional:</b></i> A version of the <a href="https://developer.microsoft.com/windows/downloads">Windows 10 SDK</a> (if you want to build the UWP projects)</li>
-    </ul>
-        <p class="note"><a href="#HowToBuildCygwin">Cygwin</a> is required if using a version of MSVC other than the one
-        compatible with the supplied project files or if other compilers are used to build ICU. (e.g. GCC)</p>
-
-    <p>The steps are:</p>
-
-    <ol>
-      <li>Unzip the <tt>icu-XXXX.zip</tt> file into any convenient location.<br/>
-        <ul class="no-left-margin">
-          <li>You can use the built-in zip functionality of Windows Explorer to do this.
-          Right-click on the .zip file and choose the "Extract All" option from the context menu.
-          This will open a new window where you can choose the output location to put the files.</li>
-          <li>Alternatively, you can use a 3<sup>rd</sup> party GUI tool like 7-Zip or WinZip to do this as well.</li>
-        </ul>
-      </li>
-
-      <li>Be sure that the ICU binary directory, (ex: <i>&lt;ICU&gt;</i><tt>\bin\</tt>), is
-      included in the <strong>PATH</strong> environment variable. The tests will
-      not work without the location of the ICU DLL files in the path.
-      Note that the binary directory name can depend on what architecture you select when you compile ICU.
-      For x86 or 32-bit builds, the binary directory is "<tt>bin</tt>". Whereas for x64 or 64-bit builds
-      the binary directory is "<tt>bin64</tt>".
-      </li>
-
-      <li>Open the "<i>&lt;ICU&gt;</i><tt>\source\allinone\allinone.sln</tt>" solution
-      file in 'Visual Studio 2017'. (This solution includes all the
-      International Components for Unicode libraries, necessary ICU building
-      tools, and the test suite projects). Please see the 
-      <a href="#HowToBuildWindowsCommandLine">command line note below</a> if you want to
-      build from the command line instead.</li>
-
-      <li>If you are building using 'Visual Studio 2015' instead, or if you are building the UWP projects and you have a different
-      version of the Windows 10 SDK installed you will first need to modify the two "<tt>Build.Windows.*.props</tt>" files
-      in the "<tt>allinone</tt>" directory before you can open the "allinone" solution file.
-      Please see the notes below about <a href="#HowToUseOtherVSVersions">building with other versions of Visual Studio</a> and the 
-      notes on <a href="#HowToRetargetTheWin10SDK">re-targeting the Windows 10 SDK for the UWP projects</a> for details. Alternatively,
-      you can <a href="#HowToSkipBuildingUWP">skip building the UWP projects</a> entirely as well.
-      </li>
-      
-      <li>Set the active platform to "Win32" or "x64" (See <a href="#HowToBuildWindowsPlatform">Windows platform note</a> below)
-      and configuration to "Debug" or "Release" (See <a href="#HowToBuildWindowsConfig">Windows configuration note</a> below).</li>
-
-      <li>Choose the "Build" menu and select "Rebuild Solution". If you want to
-      build the Debug and Release at the same time, see the <a href=
-      "#HowToBuildWindowsBatch">batch configuration note</a> below.</li>
-
-      <li>Run the tests. They can be run from the command line or from within Visual Studio.
-
-        <h4>Running the Tests from the Windows Command Line (cmd)</h4>
-        <ul>
-          <li>The general syntax is:<br />
-              <div class="indent">
-                <tt><i>&lt;ICU&gt;</i>\source\allinone\icucheck.bat  <i>Platform</i> <i>Configuration</i></tt>
-              </div>
-          </li>
-          <li>So, for example for x86 (32-bit) and Debug, use the following:<br />
-              <samp><i>&lt;ICU&gt;</i>\source\allinone\icucheck.bat  <b>x86</b> <b>Debug</b></samp>
-              For x86 (32-bit) and Release:
-              <samp><i>&lt;ICU&gt;</i>\source\allinone\icucheck.bat  <b>x86</b> <b>Release</b></samp>
-              For x64 (64-bit) and Debug:
-              <samp><i>&lt;ICU&gt;</i>\source\allinone\icucheck.bat  <b>x64</b> <b>Debug</b></samp>
-              For x64 (64-bit) and Release:
-              <samp><i>&lt;ICU&gt;</i>\source\allinone\icucheck.bat  <b>x64</b> <b>Release</b></samp>
-          </li>
-        </ul>
-
-        <h4>Running the Tests from within Visual Studio</h4>
-
-        <ol>
-          <li>Run the C++ test suite, "<tt>intltest</tt>". To do this: set the active startup
-          project to "intltest", and press Ctrl+F5 to run it. Make sure that it
-          passes without any errors.</li>
-
-          <li>Run the C test suite, "<tt>cintltst</tt>". To do this: set the active startup
-          project to "cintltst", and press Ctrl+F5 to run it. Make sure that it
-          passes without any errors.</li>
-
-          <li>Run the I/O test suite, "<tt>iotest</tt>". To do this: set the active startup
-          project to "iotest", and press Ctrl+F5 to run it. Make sure that it passes
-          without any errors.</li>
-        </ol>
-	    </li>
-
-      <li>You are now able to develop applications with ICU by using the
-      libraries and tools in <tt><i>&lt;ICU&gt;</i>\bin\</tt>. The headers are in
-      <tt><i>&lt;ICU&gt;</i>\include\</tt> and the link libraries are in
-      <tt><i>&lt;ICU&gt;</i>\lib\</tt>. To install the ICU runtime on a machine, or ship
-      it with your application, copy the needed components from
-      <tt><i>&lt;ICU&gt;</i>\bin\</tt> to a location on the system PATH or to your
-      application directory.</li>

-    <p><a name="HowToUseOtherVSVersions" id="HowToUseOtherVSVersions">
-    <strong>Building with other versions of Visual Studio Note:</strong></a>
-    The particular version of the MSVC compiler tool-set (and thus the corresponding version of Visual Studio) that
-    is used to compile ICU is determined by the "<tt>PlatformToolset</tt>" property. This property is stored in two
-    different shared files that are used to set common configuration settings amongst the various ICU "<tt>*.vcxproj</tt>" project files.
-    
-    For the non-UWP projects, this setting is in the shared file called "<tt>Build.Windows.ProjectConfiguration.props</tt>" located
-    in the "allinone" directory.
-    
-    For the UWP projects, this setting is in the shared file called "<tt>Build.Windows.UWP.ProjectConfiguration.props</tt>", also 
-    located in the "allinone" directory.
-    <br/>
-    The value of <tt>v140</tt> corresponds to the Visual Studio 2015 compiler tool set, whereas the value of

-    
-    Note however that Visual Studio 2017 is required for building the UWP projects.
-    </p>
-    
-    <p>Please consider: Using older versions of the MSVC compiler is generally not recommended due to the improved support for the C++11 standard

-    "#HowToBuildUNIX">How To Build And Install On UNIX</a>" instructions, while
-    you are inside a Cygwin bash shell. To build with Microsoft Visual C++,
-    please use the following instructions:</p>
-
-    <ol>
-      <li>Start the Windows "Command Prompt" window. This is different from the

-    <h3><a name="HowToBuildZOS" href="#HowToBuildZOS" id="HowToBuildZOS">How To
-    Build And Install On z/OS (OS/390)</a></h3>
-
-    <p>You can install ICU on z/OS or OS/390 (the previous name of z/OS), but IBM
-    tests only the z/OS installation. You install ICU in a z/OS UNIX system
-    services file system such as HFS or zFS. On this platform, it is important
-    that you understand a few details:</p>
-
-    <ul>
-      <li>The makedep and GNU make tools are required for building ICU. If it
-      is not already installed on your system, it is available at the <a href=
-      "http://www-03.ibm.com/servers/eserver/zseries/zos/unix/bpxa1toy.html">z/OS UNIX -
-      Tools and Toys</a> site. The PATH environment variable should be updated to
-      contain the location of this executable prior to build. Failure to add these
-      tools to your PATH will cause ICU build failures or cause pkgdata to fail
-      to run.</li>
-
-      <li>Since USS does not support using the mmap() function over NFS, it is
-      recommended that you build ICU on a local filesystem. Once ICU has been
-      built, you should not have this problem while using ICU when the data
-      library has been built as a shared library, which is this is the default
-      setting.</li>
-
-      <li>Encoding considerations: The source code assumes that it is compiled
-      with codepage ibm-1047 (to be exact, the UNIX System Services variant of
-      it). The pax command converts all of the source code files from ASCII to
-      codepage ibm-1047 (USS) EBCDIC. However, some files are binary files and
-      must not be converted, or must be converted back to their original state.
-      You can use the <a href="as_is/os390/unpax-icu.sh">unpax-icu.sh</a> script
-      to do this for you automatically. It will unpackage the tar file and
-      convert all the necessary files for you automatically.</li>
-
-      <li>z/OS supports both native S/390 hexadecimal floating point and (with
-      OS/390 2.6 and later) IEEE 754 binary floating point. This is a compile
-      time option. Applications built with IEEE should use ICU DLLs that are
-      built with IEEE (and vice versa). The environment variable IEEE390=0 will
-      cause the z/OS version of ICU to be built without IEEE floating point
-      support and use the native hexadecimal floating point. By default ICU is
-      built with IEEE 754 support. Native floating point support is sufficient
-      for codepage conversion, resource bundle and UnicodeString operations, but
-      the Format APIs require IEEE binary floating point.</li>
-
-      <li>z/OS introduced the concept of Extra Performance Linkage (XPLINK) to
-      bring performance improvement opportunities to call-intensive C and C++
-      applications such as ICU. XPLINK is enabled on a DLL-by-DLL basis, so if
-      you are considering using XPLINK in your application that uses ICU, you
-      should consider building the XPLINK-enabled version of ICU. You need to
-      set ICU's environment variable <code>OS390_XPLINK=1</code> prior to
-      invoking the make process to produce binaries that are enabled for
-      XPLINK. The XPLINK option, which is available for z/OS 1.2 and later,
-      requires the PTF PQ69418 to build XPLINK enabled binaries.</li>
-
-      <li>ICU requires XPLINK for the icuio library. If you want to use the
-      rest of ICU without XPLINK, then you must use the --disable-icuio
-      configure option.</li>
-
-      <li>The latest versions of z/OS use <a
-      href="https://www.ibm.com/support/knowledgecenter/SSLTBW_2.2.0/com.ibm.zos.v2r2.cbcux01/oebind6.htm">XPLINK

-      </li>
-
-
-      <li>The rest of the instructions for building and testing ICU on z/OS with
-      UNIX System Services are the same as the <a href="#HowToBuildUNIX">How To
-      Build And Install On UNIX</a> section.</li>
-    </ul>
-
-    <h4>z/OS (Batch/PDS) support outside the UNIX system services
-    environment</h4>
-
-    <p>By default, ICU builds its libraries into the UNIX file system (HFS). In
-    addition, there is a z/OS specific environment variable (OS390BATCH) to build
-    some libraries into the z/OS native file system. This is useful, for example,
-    when your application is externalized via Job Control Language (JCL).</p>
-
-    <p>The OS390BATCH environment variable enables non-UNIX support including the
-    batch environment. When OS390BATCH is set, the libicui18n<i>XX</i>.dll,
-    libicuuc<i>XX</i>.dll, and libicudt<i>XX</i>e.dll binaries are built into
-    data sets (the native file system). Turning on OS390BATCH does not turn off
-    the normal z/OS UNIX build. This means that the z/OS UNIX (HFS) DLLs will
-    always be created.</p>
-
-    <p>Two additional environment variables indicate the names of the z/OS data
-    sets to use. The LOADMOD environment variable identifies the name of the data
-    set that contains the dynamic link libraries (DLLs) and the LOADEXP
-    environment variable identifies the name of the data set that contains the
-    side decks, which are normally the files with the .x suffix in the UNIX file
-    system.</p>
-
-    <p>A data set is roughly equivalent to a UNIX or Windows file. For most kinds
-    of data sets the operating system maintains record boundaries. UNIX and
-    Windows files are byte streams. Two kinds of data sets are PDS and PDSE. Each
-    data set of these two types contains a directory. It is like a UNIX
-    directory. Each "file" is called a "member". Each member name is limited to
-    eight bytes, normally EBCDIC.</p>
-
-    <p>Here is an example of some environment variables that you can set prior to
-    building ICU:</p>
-<pre>
-<samp>OS390BATCH=1
-LOADMOD=<i>USER</i>.ICU.LOAD
-LOADEXP=<i>USER</i>.ICU.EXP</samp>
-</pre>
-
-    <p>The PDS member names for the DLL file names are as follows:</p>
-<pre>
-<samp>IXMI<i>XX</i>IN --&gt; libicui18n<i>XX</i>.dll
-IXMI<i>XX</i>UC --&gt; libicuuc<i>XX</i>.dll
-IXMI<i>XX</i>DA --&gt; libicudt<i>XX</i>e.dll</samp>
-</pre>
-
-    <p>You should point the LOADMOD environment variable at a partitioned data
-    set extended (PDSE) and point the LOADEXP environment variable at a
-    partitioned data set (PDS). The PDSE can be allocated with the following
-    attributes:</p>
-<pre>
-<samp>Data Set Name . . . : <i>USER</i>.ICU.LOAD
-Management class. . : <i>**None**</i>
-Storage class . . . : <i>BASE</i>

-		<p>This section will explain how to build ICU on one platform, but to produce binaries intended to run on another. This is commonly known as a cross compile.</p>
-		<p>Normally, in the course of a build, ICU needs to run the tools that it builds in order to generate and package data and test-data.In a cross compilation setting, ICU is built on a different system from that which it eventually runs on. An example might be, if you are building for a small/headless system (such as an embedded device), or a system where you can't easily run the ICU command line tools (any non-UNIX-like system).</p>
-		<p>To reduce confusion, we will here refer to the "A" and the "B" system.System "A" is the actual system we will be running on- the only requirements on it is are it is able to build ICU from the command line targetting itself (with configure or runConfigureICU), and secondly, that it also contain the correct toolchain for compiling and linking for the resultant platform, referred to as the "B" system.</p>
-		<p>The autoconf docs use the term "build" for A, and "host" for B. More details at: <a href="http://www.gnu.org/software/autoconf/manual/html_node/Specifying-Names.html#Specifying-Names">http://www.gnu.org/software/autoconf/manual/html_node/Specifying-Names.html</a></p>

-
-		<ol>
-		<li>Check out or unpack the ICU source code into the /icu directory.You will have the directories /icu/source, etc.</li>
-		<li>Build ICU in /buildA normally (using runConfigureICU or configure):
-<pre class="samp">cd /buildA
-sh /icu/source/runConfigureICU <strong>MacOSX</strong>
-gnumake

-		</li>
-		<li>Set PATH or other variables as needed, such as CPPFLAGS.</li>
-		<li>Build ICU in /buildB<br />
-			<p class="note">"<code>--with-cross-build</code>" takes an absolute path.</p>

-sh /icu/source/configure --host=<strong>i586-pc-haiku</strong> --with-cross-build=<strong>/buildA</strong>

-    <h2><a name="HowToPackage" href="#HowToPackage" id="HowToPackage">How To
-    Package ICU</a></h2>
-
-    <p>There are many ways that a person can package ICU with their software
-    products. Usually only the libraries need to be considered for packaging.</p>
-
-    <p>On UNIX, you should use "<tt>gmake install</tt>" to make it easier to
-    develop and package ICU. The bin, lib and include directories are needed to
-    develop applications that use ICU. These directories will be created relative
-    to the "<tt>--prefix=</tt><i>dir</i>" configure option (See the <a href=
-    "#HowToBuildUNIX">UNIX build instructions</a>). When ICU is built on Windows,
-    a similar directory structure is built.</p>
-
-    <p>When changes have been made to the standard ICU distribution, it is
-    recommended that at least one of the following guidelines be followed for
-    special packaging.</p>
-
-    <ol>
-      <li>Add a suffix name to the library names. This can be done with the
-      --with-library-suffix configure option.</li>
-
-      <li>The installation script should install the ICU libraries into the
-      application's directory.</li>
-    </ol>
-
-    <p>Following these guidelines prevents other applications that use a standard
-    ICU distribution from conflicting with any libraries that you need. On
-    operating systems that do not have a standard C++ ABI (name mangling) for
-    compilers, it is recommended to do this special packaging anyway. More
-    details on customizing ICU are available in the <a href=
-    "http://userguide.icu-project.org/">User's Guide</a>. The <a href=
-    "#SourceCode">ICU Source Code Organization</a> section of this readme.html
-    gives a more complete description of the libraries.</p>

-    <p>Normally only the above ICU libraries need to be considered for packaging.
-    The versionless symbolic links to these libraries are only needed for easier
-    development. The <i>X</i>, <i>Y</i> and <i>Z</i> parts of the name are the
-    version numbers of ICU. For example, ICU 2.0.2 would have the name
-    libicuuc.so.20.2 for the common library. The exact format of the library
-    names can vary between platforms due to how each platform can handles library
-    versioning.</p>

-
-    <h3><a name="ImportantNotesMultithreaded" href="#ImportantNotesMultithreaded"
-    id="ImportantNotesMultithreaded">Using ICU in a Multithreaded
-    Environment</a></h3>
-
-    <p>Some versions of ICU require calling the <code>u_init()</code> function
-    from <code>uclean.h</code> to ensure that ICU is initialized properly. In
-    those ICU versions, <code>u_init()</code> must be called before ICU is used
-    from multiple threads. There is no harm in calling <code>u_init()</code> in a
-    single-threaded application, on a single-CPU machine, or in other cases where
-    <code>u_init()</code> is not required.</p>
-
-    <p>In addition to ensuring thread safety, <code>u_init()</code> also attempts
-    to load at least one ICU data file. Assuming that all data files are packaged
-    together (or are in the same folder in files mode), a failure code from
-    <code>u_init()</code> usually means that the data cannot be found. In this
-    case, the data may not be installed properly, or the application may have
-    failed to call <code>udata_setCommonData()</code> or
-    <code>u_setDataDirectory()</code> which specify to ICU where it can find its
-    data.</p>
-
-    <p>Since <code>u_init()</code> will load only one or two data files, it
-    cannot guarantee that all of the data that an application needs is available.
-    It cannot check for all data files because the set of files is customizable,
-    and some ICU services work without loading any data at all. An application
-    should always check for error codes when opening ICU service objects (using
-    <code>ucnv_open()</code>, <code>ucol_open()</code>, C++ constructors,
-    etc.).</p>
-
-    <h4>ICU 3.4 and later</h4>
-
-    <p>ICU 3.4 self-initializes properly for multi-threaded use. It achieves this
-    without performance penalty by hardcoding the core Unicode properties data,
-    at the cost of some flexibility. (For details see Jitterbug 4497.)</p>
-
-    <p><code>u_init()</code> can be used to check for data loading. It tries to
-    load the converter alias table (<code>cnvalias.icu</code>).</p>
-
-    <h4>ICU 2.6..3.2</h4>
-
-    <p>These ICU versions require a call to <code>u_init()</code> before
-    multi-threaded use. The services that are directly affected are those that
-    don't have a service object and need to be fast: normalization and character
-    properties.</p>
-
-    <p><code>u_init()</code> loads and initializes the data files for
-    normalization and character properties (<code>unorm.icu</code> and
-    <code>uprops.icu</code>) and can therefore also be used to check for data
-    loading.</p>
-
-    <h4>ICU 2.4 and earlier</h4>
-
-    <p>ICU 2.4 and earlier versions were not prepared for multithreaded use on
-    multi-CPU platforms where the CPUs implement weak memory coherency. These
-    CPUs include: Power4, Power5, Alpha, Itanium. <code>u_init()</code> was not
-    defined yet.</p>

-    compiler flag is used. It is required in order to use the latest

-
-    <p>In order to avoid synchronization and threading issues, developers are
-    <strong>suggested</strong> to strictly follow the compiling and linking
-    guidelines for multithreaded applications, specified in the following
-    SUn Solaris document available from Oracle. Most notably, pay strict attention to the
-    following statements from Sun:</p>
-
-    <blockquote>
-      <p>To use libthread, specify -lthread before -lc on the ld command line, or
-      last on the cc command line.</p>
-
-      <p>To use libpthread, specify -lpthread before -lc on the ld command line,
-      or last on the cc command line.</p>
-    </blockquote>
-
-    <p>Failure to do this may cause spurious lock conflicts, recursive mutex
-    failure, and deadlock.</p>

-    <h3><a name="ImportantNotesWindows" href="#ImportantNotesWindows" id=
-    "ImportantNotesWindows">Windows Platform</a></h3>
-
-    <p>If you are building on the Windows platform, it is important that you
-    understand a few of the following build details.</p>
-
-    <h4>DLL directories and the PATH setting</h4>
-
-    <p>As delivered, the International Components for Unicode build as several
-    DLLs, which are placed in the "<i>&lt;ICU&gt;</i>\bin64" directory. You must
-    add this directory to the PATH environment variable in your system, or any
-    executables you build will not be able to access International Components for
-    Unicode libraries. Alternatively, you can copy the DLL files into a directory
-    already in your PATH, but we do not recommend this. You can wind up with
-    multiple copies of the DLL and wind up using the wrong one.</p>
-
-    <h4><a name="ImportantNotesWindowsPath" id=
-    "ImportantNotesWindowsPath">Changing your PATH</a></h4>
-
-    <p><strong>Windows 2000/XP and above</strong>: Use the System Icon in the Control
-    Panel. Pick the "Advanced" tab. Select the "Environment Variables..."
-    button. Select the variable PATH in the lower box, and select the lower
-    "Edit..." button. In the "Variable Value" box, append the string
-    ";<i>&lt;ICU&gt;</i>\bin64" to the end of the path string. If there is
-    nothing there, just type in "<i>&lt;ICU&gt;</i>\bin64". Click the Set button,
-    then the OK button.</p>
-
-    <p>Note: When packaging a Windows application for distribution and
-    installation on user systems, copies of the ICU DLLs should be included with
-    the application, and installed for exclusive use by the application. This is
-    the only way to insure that your application is running with the same version
-    of ICU, built with exactly the same options, that you developed and tested
-    with. Refer to Microsoft's guidelines on the usage of DLLs, or search for the
-    phrase "DLL hell" on <a href=
-    "http://msdn.microsoft.com/">msdn.microsoft.com</a>.</p>
-
-    <h3><a name="ImportantNotesUNIX" href="#ImportantNotesUNIX" id=
-    "ImportantNotesUNIX">UNIX Type Platform</a></h3>
-
-    <p>If you are building on a UNIX platform, and if you are installing ICU in a
-    non-standard location, you may need to add the location of your ICU libraries
-    to your <strong>LD_LIBRARY_PATH</strong> or <strong>LIBPATH</strong>
-    environment variable (or the equivalent runtime library path environment
-    variable for your system). The ICU libraries may not link or load properly
-    without doing this.</p>
-
-    <p>Note that if you do not want to have to set this variable, you may instead
-    use the --enable-rpath option at configuration time. This option will
-    instruct the linker to always look for the libraries where they are
-    installed. You will need to use the appropriate linker options when linking
-    your own applications and libraries against ICU, too. Please refer to your
-    system's linker manual for information about runtime paths. The use of rpath
-    also means that when building a new version of ICU you should not have an
-    older version installed in the same place as the new version's installation
-    directory, as the older libraries will used during the build, instead of the
-    new ones, likely leading to an incorrectly build ICU. This is the proper
-    behavior of rpath.</p>

-
-    <h3><a name="PlatformDependenciesNew" href="#PlatformDependenciesNew" id=
-    "PlatformDependenciesNew">Porting To A New Platform</a></h3>
-
-    <p>If you are using ICU's Makefiles to build ICU on a new platform, there are
-    a few places where you will need to add or modify some files. If you need
-    more help, you can always ask the <a href=
-    "http://site.icu-project.org/contacts">icu-support mailing list</a>. Once
-    you have finished porting ICU to a new platform, it is recommended that you
-    contribute your changes back to ICU via the icu-support mailing list. This
-    will make it easier for everyone to benefit from your work.</p>
-
-    <h4>Data For a New Platform</h4>
-
-    <p>For some people, it may not be necessary for completely build ICU. Most of
-    the makefiles and build targets are for tools that are used for building
-    ICU's data, and an application's data (when an application uses ICU resource
-    bundles for its data).</p>
-
-    <p>Data files can be built on a different platform when both platforms share
-    the same endianness and the same charset family. This assertion does not
-    include platform dependent DLLs/shared/static libraries. For details see the
-    User Guide <a href="http://userguide.icu-project.org/icudata">ICU
-    Data</a> chapter.</p>
-
-    <p>ICU 3.6 removes the requirement that ICU be completely built in the native
-    operating environment. It adds the icupkg tool which can be run on any
-    platform to turn binary ICU data files from any one of the three formats into
-    any one of the other data formats. This allows a application to use ICU data
-    built anywhere to be used for any other target platform.</p>
-
-    <p><strong>WARNING!</strong> Building ICU without running the tests is not
-    recommended. The tests verify that ICU is safe to use. It is recommended that
-    you try to completely port and test ICU before using the libraries for your
-    own application.</p>
-
-    <h4>Adapting Makefiles For a New Platform</h4>
-
-    <p>Try to follow the build steps from the <a href="#HowToBuildUNIX">UNIX</a>
-    build instructions. If the configure script fails, then you will need to
-    modify some files. Here are the usual steps for porting to a new
-    platform:<br />
-    </p>
-
-    <ol>
-      <li>Create an mh file in icu/source/config/. You can use mh-linux or a
-      similar mh file as your base configuration.</li>
-
-      <li>Modify icu/source/aclocal.m4 to recognize your platform's mh file.</li>
-
-      <li>Modify icu/source/configure.in to properly set your <b>platform</b> C
-      Macro define.</li>
-
-      <li>Run <a href="http://www.gnu.org/software/autoconf/">autoconf</a> in
-      icu/source/ without any options. The autoconf tool is standard on most
-      Linux systems.</li>
-
-      <li>If you have any optimization options that you want to normally use, you
-      can modify icu/source/runConfigureICU to specify those options for your
-      platform.</li>
-
-      <li>Build and test ICU on your platform. It is very important that you run
-      the tests. If you don't run the tests, there is no guarentee that you have

-    <h3><a name="PlatformDependenciesImpl" href="#PlatformDependenciesImpl" id=
-    "PlatformDependenciesImpl">Platform Dependent Implementations</a></h3>
-
-    <p>The platform dependencies have been mostly isolated into the following
-    files in the common library. This information can be useful if you are
-    porting ICU to a new platform.</p>
-
-    <ul>
-      <li>
-        <strong>unicode/platform.h.in</strong> (autoconf'ed platforms)<br />
-         <strong>unicode/p<i>XXXX</i>.h</strong> (others: pwin32.h, ppalmos.h,
-        ..): Platform-dependent typedefs and defines:<br />
-        <br />
-
-
-        <ul>
-          <li>Generic types like UBool, int8_t, int16_t, int32_t, int64_t,
-          uint64_t etc.</li>
-
-          <li>U_EXPORT and U_IMPORT for specifying dynamic library import and
-          export</li>
-
-          <li>String handling support for the char16_t and wchar_t types.</li>
-        </ul>
-        <br />
-      </li>
-
-      <li>
-        <strong>unicode/putil.h, putil.c</strong>: platform-dependent
-        implementations of various functions that are platform dependent:<br />
-        <br />
-
-
-        <ul>
-          <li>uprv_isNaN, uprv_isInfinite, uprv_getNaN and uprv_getInfinity for
-          handling special floating point values.</li>
-
-          <li>uprv_tzset, uprv_timezone, uprv_tzname and time for getting
-          platform specific time and time zone information.</li>
-
-          <li>u_getDataDirectory for getting the default data directory.</li>
-
-          <li>uprv_getDefaultLocaleID for getting the default locale
-          setting.</li>
-
-          <li>uprv_getDefaultCodepage for getting the default codepage
-          encoding.</li>
-        </ul>
-        <br />
-      </li>
-
-      <li>
-        <strong>umutex.h, umutex.c</strong>: Code for doing synchronization in
-        multithreaded applications. If you wish to use International Components
-        for Unicode in a multithreaded application, you must provide a
-        synchronization primitive that the classes can use to protect their
-        global data against simultaneous modifications. We already supply working
-        implementations for many platforms that ICU builds on.<br />
-        <br />
-      </li>
-
-      <li><strong>umapfile.h, umapfile.c</strong>: functions for mapping or
-      otherwise reading or loading files into memory. All access by ICU to data
-      from files makes use of these functions.<br />
-      <br />
-      </li>
-
-      <li>Using platform specific #ifdef macros are highly discouraged outside of
-      the scope of these files. When the source code gets updated in the future,
-      these #ifdef's can cause testing problems for your platform.</li>
-    </ul>

- * This file defines five types of data structures: singly-linked lists,
- * lists, simple queues, tail queues and XOR simple queues.
- *
- *
- * A singly-linked list is headed by a single forward pointer. The elements
- * are singly linked for minimum space and pointer manipulation overhead at
- * the expense of O(n) removal for arbitrary elements. New elements can be
- * added to the list after an existing element or at the head of the list.
- * Elements being removed from the head of the list should use the explicit
- * macro for this purpose for optimum efficiency. A singly-linked list may
- * only be traversed in the forward direction.  Singly-linked lists are ideal
- * for applications with large datasets and few or no removals or for
- * implementing a LIFO queue.
- *
- * A list is headed by a single forward pointer (or an array of forward
- * pointers for a hash table header). The elements are doubly linked
- * so that an arbitrary element can be removed without a need to
- * traverse the list. New elements can be added to the list before
- * or after an existing element or at the head of the list. A list
- * may only be traversed in the forward direction.
- *
- * A simple queue is headed by a pair of pointers, one to the head of the
- * list and the other to the tail of the list. The elements are singly
- * linked to save space, so elements can only be removed from the
- * head of the list. New elements can be added to the list before or after
- * an existing element, at the head of the list, or at the end of the
- * list. A simple queue may only be traversed in the forward direction.
- *
- * A tail queue is headed by a pair of pointers, one to the head of the
- * list and the other to the tail of the list. The elements are doubly
- * linked so that an arbitrary element can be removed without a need to
- * traverse the list. New elements can be added to the list before or
- * after an existing element, at the head of the list, or at the end of
- * the list. A tail queue may be traversed in either direction.
- *
- * An XOR simple queue is used in the same way as a regular simple queue.
- * The difference is that the head structure also includes a "cookie" that
- * is XOR'd with the queue pointer (first, last or next) to generate the
- * real pointer value.
- *
- * For details on the use of these macros, see the queue(3) manual page.

-PostgreSQL Database Management System
-=====================================
-
-This directory contains the source code distribution of the PostgreSQL
-database management system.
-
-PostgreSQL is an advanced object-relational database management system
-that supports an extended subset of the SQL standard, including
-transactions, foreign keys, subqueries, triggers, user-defined types
-and functions.  This distribution also contains C language bindings.
-
-PostgreSQL has many language interfaces, many of which are listed here:
-
-	https://www.postgresql.org/download/
-
-See the file INSTALL for instructions on how to build and install
-PostgreSQL.  That file also lists supported operating systems and
-hardware platforms and contains information regarding any other
-software packages that are required to build or run the PostgreSQL
-system.  Copyright and license information can be found in the
-file COPYRIGHT.  A comprehensive documentation set is included in this
-distribution; it can be read as described in the installation
-instructions.
-
-The latest version of this software may be obtained at
-https://www.postgresql.org/download/.  For more information look at our
-web site located at https://www.postgresql.org/.

-(This file does not appear in release tarballs.)
-
-In a release or snapshot tarball of PostgreSQL, a documentation file named
-INSTALL will appear in this directory.  However, this file is not stored in
-git and so will not be present if you are using a git checkout.
-
-If you are using a git checkout, you can view the most recent installation
-instructions at:
-	https://www.postgresql.org/docs/devel/installation.html
-
-Users compiling from git will also need compatible versions of Bison, Flex,
-and Perl, as discussed in the install documentation.  These programs are not
-needed when using a tarball, since the files they are needed to build are
-already present in the tarball.  (On Windows, however, you need Perl anyway.)

- *	Signal stuff
- *
- *	For WIN32, there is no wait() call so there are no wait() macros
- *	to interpret the return value of system().  Instead, system()
- *	return values < 0x100 are used for exit() termination, and higher
- *	values are used to indicate non-exit() termination, which is
- *	similar to a unix-style signal exit (think SIGSEGV ==
- *	STATUS_ACCESS_VIOLATION).  Return values are broken up into groups:
- *
- *	https://docs.microsoft.com/en-us/windows-hardware/drivers/kernel/using-ntstatus-values
- *
- *		NT_SUCCESS			0 - 0x3FFFFFFF
- *		NT_INFORMATION		0x40000000 - 0x7FFFFFFF
- *		NT_WARNING			0x80000000 - 0xBFFFFFFF
- *		NT_ERROR			0xC0000000 - 0xFFFFFFFF
- *
- *	Effectively, we don't care on the severity of the return value from
- *	system(), we just need to know if it was because of exit() or generated
- *	by the system, and it seems values >= 0x100 are system-generated.
- *	See this URL for a list of WIN32 STATUS_* values:
- *
- *		Wine (URL used in our error messages) -
- *			http://source.winehq.org/source/include/ntstatus.h
- *		Descriptions -
- *			https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-erref/596a1078-e883-4972-9bbc-49e60bebca55
- *
- *	The comprehensive exception list is included in ntstatus.h from the
- *	Windows	Driver Kit (WDK).  A subset of the list is also included in
- *	winnt.h from the Windows SDK.  Defining WIN32_NO_STATUS before including
- *	windows.h helps to avoid any conflicts.
- *
- *	Some day we might want to print descriptions for the most common
- *	exceptions, rather than printing an include file name.  We could use
- *	RtlNtStatusToDosError() and pass to FormatMessage(), which can print
- *	the text of error values, but MinGW does not support
- *	RtlNtStatusToDosError().

- * As of PostgreSQL 9.3, we normally allocate only a very small amount of
- * System V shared memory, and only for the purposes of providing an
- * interlock to protect the data directory.  The real shared memory block
- * is allocated using mmap().  This works around the problem that many
- * systems have very low limits on the amount of System V shared memory
- * that can be allocated.  Even a limit of a few megabytes will be enough
- * to run many copies of PostgreSQL without needing to adjust system settings.
- *
- * We assume that no one will attempt to run PostgreSQL 9.3 or later on
- * systems that are ancient enough that anonymous shared memory is not
- * supported, such as pre-2.4 versions of Linux.  If that turns out to be
- * false, we might need to add compile and/or run-time tests here and do this
- * only if the running kernel supports it.
- *
- * However, we must always disable this logic in the EXEC_BACKEND case, and
- * fall back to the old method of allocating the entire segment using System V
- * shared memory, because there's no way to attach an anonymous mmap'd segment
- * to a process after exec().  Since EXEC_BACKEND is intended only for
- * developer use, this shouldn't be a big problem.  Because of this, we do
- * not worry about supporting anonymous shmem in the EXEC_BACKEND cases below.
- *
- * As of PostgreSQL 12, we regained the ability to use a large System V shared

- * crashdump.c
- *		   Automatic crash dump creation for PostgreSQL on Windows
- *
- * The crashdump feature traps unhandled win32 exceptions produced by the
- * backend, and tries to produce a Windows MiniDump crash
- * dump for later debugging and analysis. The machine performing the dump
- * doesn't need any special debugging tools; the user only needs to send
- * the dump to somebody who has the same version of PostgreSQL and has debugging
- * tools.
- *
- * crashdump module originally by Craig Ringer <ringerc@ringerc.id.au>
- *
- * LIMITATIONS
- * ===========
- * This *won't* work in hard OOM situations or stack overflows.
- *
- * For those, it'd be necessary to take a much more complicated approach where
- * the handler switches to a new stack (if it can) and forks a helper process
- * to debug it self.
- *
- * POSSIBLE FUTURE WORK
- * ====================
- * For bonus points, the crash dump format permits embedding of user-supplied
- * data. If there's anything else that should always be supplied with a crash
- * dump (postgresql.conf? Last few lines of a log file?), it could potentially
- * be added, though at the cost of a greater chance of the crash dump failing.

-libpgport
-=========
-
-libpgport must have special behavior.  It supplies functions to both
-libraries and applications.  However, there are two complexities:
-
-1)  Libraries need to use object files that are compiled with exactly
-the same flags as the library.  libpgport might not use the same flags,
-so it is necessary to recompile the object files for individual
-libraries.  This is done by removing -lpgport from the link line:
-
-        # Need to recompile any libpgport object files
-        LIBS := $(filter-out -lpgport, $(LIBS))
-
-and adding infrastructure to recompile the object files:
-
-        OBJS= execute.o typename.o descriptor.o data.o error.o prepare.o memory.o \
-                connect.o misc.o path.o exec.o \
-                $(filter strlcat.o, $(LIBOBJS))
-
-The problem is that there is no testing of which object files need to be
-added, but missing functions usually show up when linking user
-applications.
-
-2) For applications, we use -lpgport before -lpq, so the static files
-from libpgport are linked first.  This avoids having applications
-dependent on symbols that are _used_ by libpq, but not intended to be
-exported by libpq.  libpq's libpgport usage changes over time, so such a
-dependency is a problem.  Windows, Linux, AIX, and macOS use an export
-list to control the symbols exported by libpq.

- * 1. No locale support: the radix character is always '.' and the '

- *
- * 2. No support for the "%n" format specification.
- *
- * 3. No support for wide characters ("lc" and "ls" formats).
- *
- * 4. No support for "long double" ("Lf" and related formats).
- *
- * 5. Space and '#' flags are not implemented.
- *
- * In addition, we support some extensions over C99:
- *
- * 1. Argument order control through "%n$" and "*n$", as required by POSIX.
- *
- * 2. "%m" expands to the value of strerror(errno), where errno is the
- * value that variable had at the start of the call.  This is a glibc
- * extension, but a very useful one.
- *
- *
- * Historically the result values of sprintf/snprintf varied across platforms.
- * This implementation now follows the C99 standard:
- *
- * 1. -1 is returned if an error is detected in the format string, or if
- * a write to the target stream fails (as reported by fwrite).  Note that
- * overrunning snprintf's target buffer is *not* an error.
- *
- * 2. For successful writes to streams, the actual number of bytes written
- * to the stream is returned.
- *
- * 3. For successful sprintf/snprintf, the number of bytes that would have
- * been written to an infinite-size buffer (excluding the trailing '\0')
- * is returned.  snprintf will truncate its output to fit in the buffer
- * (ensuring a trailing '\0' unless count == 0), but this is not reflected
- * in the function result.
- *
- * snprintf buffer overrun can be detected by checking for function result
- * greater than or equal to the supplied count.

- *
- *	 - no /S switch

- *	 - no special characters between the two quote characters, where special
- *	   is one of: &<>()@^|
- *	 - there are one or more whitespace characters between the two quote
- *	   characters
- *	 - the string between the two quote characters is the name of an
- *	   executable file.
- *
- *	 2. Otherwise, old behavior is to see if the first character is a quote

- *	Threading sometimes requires specially-named versions of functions

- *	strerror().  Other operating systems use pthread_setspecific()
- *	and pthread_getspecific() internally to allow standard library
- *	functions to return static data to threaded applications. And some
- *	operating systems have neither.
- *
- *	Additional confusion exists because many operating systems that
- *	use pthread_setspecific/pthread_getspecific() also have *_r versions
- *	of standard library functions for compatibility with operating systems
- *	that require them.  However, internally, these *_r functions merely
- *	call the thread-safe standard library functions.
- *
- *	For example, BSD/OS 4.3 uses Bind 8.2.3 for getpwuid().  Internally,
- *	getpwuid() calls pthread_setspecific/pthread_getspecific() to return
- *	static data to the caller in a thread-safe manner.  However, BSD/OS
- *	also has getpwuid_r(), which merely calls getpwuid() and shifts
- *	around the arguments to match the getpwuid_r() function declaration.
- *	Therefore, while BSD/OS has getpwuid_r(), it isn't required.  It also
- *	doesn't have strerror_r(), so we can't fall back to only using *_r
- *	functions for threaded programs.
- *
- *	The current setup is to try threading in this order:
- *
- *		use *_r function names if they exit
- *			(*_THREADSAFE=yes)
- *		use non-*_r functions if they are thread-safe
- *
- *	One thread-safe solution for gethostbyname() might be to use getaddrinfo().

- *
- * The setlocale() function in Windows is broken in two ways. First, it
- * has a problem with locale names that have a dot in the country name. For
- * example:
- *
- * "Chinese (Traditional)_Hong Kong S.A.R..950"
- *
- * For some reason, setlocale() doesn't accept that as argument, even though
- * setlocale(LC_ALL, NULL) returns exactly that. Fortunately, it accepts
- * various alternative names for such countries, so to work around the broken
- * setlocale() function, we map the troublemaking locale names to accepted
- * aliases, before calling setlocale().
- *
- * The second problem is that the locale name for "Norwegian (Bokm&aring;l)"
- * contains a non-ASCII character. That's problematic, because it's not clear
- * what encoding the locale name itself is supposed to be in, when you
- * haven't yet set a locale. Also, it causes problems when the cluster
- * contains databases with different encodings, as the locale name is stored
- * in the pg_database system catalog. To work around that, when setlocale()
- * returns that locale name, map it to a pure-ASCII alias for the same
- * locale.
