- * 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

- *
- * New and required in version 5:

- *                      15.. 6 reserved for flags whose addition will break
