| * \brief C API: Deprecated macros for Unicode string handling |
| */ |
| |
| /** |
| * |
| * The macros in utf_old.h are all deprecated and their use discouraged. |
| * Some of the design principles behind the set of UTF macros |
| * have changed or proved impractical. |
| * Almost all of the old "UTF macros" are at least renamed. |
| * If you are looking for a new equivalent to an old macro, please see the |
| * comment at the old one. |
| * |
| * utf_old.h is included by utf.h after unicode/umachine.h |
| * and some common definitions, to not break old code. |
| * |
| * Brief summary of reasons for deprecation: |
| * - Switch on UTF_SIZE (selection of UTF-8/16/32 default string processing) |
| * was impractical. |
| * - Switch on UTF_SAFE etc. (selection of unsafe/safe/strict default string processing) |
| * was of little use and impractical. |
| * - Whole classes of macros became obsolete outside of the UTF_SIZE/UTF_SAFE |
| * selection framework: UTF32_ macros (all trivial) |
| * and UTF_ default and intermediate macros (all aliases). |
| * - The selection framework also caused many macro aliases. |
| * - Change in Unicode standard: "irregular" sequences (3.0) became illegal (3.2). |
| * - Change of language in Unicode standard: |
| * Growing distinction between internal x-bit Unicode strings and external UTF-x |
| * forms, with the former more lenient. |
| * Suggests renaming of UTF16_ macros to U16_. |
| * - The prefix "UTF_" without a width number confused some users. |
| * - "Safe" append macros needed the addition of an error indicator output. |
| * - "Safe" UTF-8 macros used legitimate (if rarely used) code point values |
| * to indicate error conditions. |
| * - The use of the "_CHAR" infix for code point operations confused some users. |
| * |
| * More details: |
| * |
| * Until ICU 2.2, utf.h theoretically allowed to choose among UTF-8/16/32 |
| * for string processing, and among unsafe/safe/strict default macros for that. |
| * |
| * It proved nearly impossible to write non-trivial, high-performance code |
| * that is UTF-generic. |
| * Unsafe default macros would be dangerous for default string processing, |
| * and the main reason for the "strict" versions disappeared: |
| * Between Unicode 3.0 and 3.2 all "irregular" UTF-8 sequences became illegal. |
| * The only other conditions that "strict" checked for were non-characters, |
| * which are valid during processing. 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. |
