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.
