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. */ #ifndef __UTF_OLD_H__ #define __UTF_OLD_H__ #include "unicode/utf.h" #include "unicode/utf8.h" #include "unicode/utf16.h" /** * \def U_HIDE_OBSOLETE_UTF_OLD_H * * Hides the obsolete definitions in unicode/utf_old.h. * Recommended to be set to 1 at compile time to make sure * the long-deprecated macros are no longer used. * * For reasons for the deprecation see the utf_old.h file comments. * * @internal */ #ifndef U_HIDE_OBSOLETE_UTF_OLD_H #define U_HIDE_OBSOLETE_UTF_OLD_H … #endif #if !defined(U_HIDE_DEPRECATED_API) && !U_HIDE_OBSOLETE_UTF_OLD_H /* Formerly utf.h, part 1 --------------------------------------------------- */ #ifdef U_USE_UTF_DEPRECATES /** * Unicode string and array offset and index type. * ICU always counts Unicode code units (UChars) for * string offsets, indexes, and lengths, not Unicode code points. * * @obsolete ICU 2.6.
