* 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

* 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

+ * 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.
+ * 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

- * - 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

- *
- * In string comparisons, two UnicodeString objects that are both "bogus"
- * compare equal (to be transitive and prevent endless loops in sorting),
