* (the most common case) or with a matched pair of special code units 192b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * ("surrogates"). The data type for code units is UChar. 193b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * For single-character handling, a Unicode character code <em>point</em> is a value 194b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * in the range 0..0x10ffff.

In particular: 206b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * - If indexes are out of bounds for a UnicodeString object 207b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * (<0 or >length()) then they are "pinned" to the nearest boundary. 208b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * - If primitive string pointer values (e.g., const UChar * or char *) 209b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * for input strings are NULL, then those input string parameters are treated 210b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * as if they pointed to an empty string. 211b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * However, this is <em>not</em> the case for char * parameters for charset names 212b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * or other IDs. 213b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * - Most UnicodeString methods do not take a UErrorCode parameter because 214b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * there are usually very few opportunities for failure other than a shortage 215b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * of memory, error codes in low-level C++ string methods would be inconvenient, 216b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * and the error code as the last parameter (ICU convention) would prevent 217b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * the use of default parameter values. 218b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * Instead, such methods set the UnicodeString into a "bogus" state 219b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * (see isBogus()) if an error occurs. 220b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * 221b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * In string comparisons, two UnicodeString objects that are both "bogus" 222b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * compare equal (to be transitive and prevent endless loops in sorting), 223b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * and a "bogus" string compares less than any non-"bogus" one. 224b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * 225b13da9df870a61b11249bf741347908dbea0edd8Jean-Baptiste Queru * Const UnicodeString methods are thread-safe.
