<p>The macros in <a class="el" href="utf__old_8h.html" title="C API: Deprecated macros for Unicode string handling.">utf_old.h</a> are all deprecated and their use discouraged. </p>
<p>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.</p>
<p><a class="el" href="utf__old_8h.html" title="C API: Deprecated macros for Unicode string handling.">utf_old.h</a> is included by <a class="el" href="utf_8h.html" title="C API: Code point macros.">utf.h</a> after <a class="el" href="umachine_8h.html" title="Basic types and constants for UTF.">unicode/umachine.h</a> and some common definitions, to not break old code.</p>
<p>Brief summary of reasons for deprecation:</p>
<ul>
<li>Switch on UTF_SIZE (selection of UTF-8/16/32 default string processing) was impractical.</li>
<li>Switch on UTF_SAFE etc. (selection of unsafe/safe/strict default string processing) was of little use and impractical.</li>
<li>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).</li>
<li>The selection framework also caused many macro aliases.</li>
<li>Change in Unicode standard: "irregular" sequences (3.0) became illegal (3.2).</li>
<li>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_.</li>
<li>The prefix "UTF_" without a width number confused some users.</li>
<li>"Safe" append macros needed the addition of an error indicator output.</li>
<li>"Safe" UTF-8 macros used legitimate (if rarely used) code point values to indicate error conditions.</li>
<li>The use of the "_CHAR" infix for code point operations confused some users.</li>
</ul>
<p>More details:</p>
<p>Until ICU 2.2, <a class="el" href="utf_8h.html" title="C API: Code point macros.">utf.h</a> theoretically allowed to choose among UTF-8/16/32 for string processing, and among unsafe/safe/strict default macros for that.</p>
<p>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.</p>
<p>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.</p>
<p>The entire contents of <a class="el" href="utf32_8h.html" title="C API: UTF-32 macros.">utf32.h</a> was moved here without replacement because all those macros were trivial and were meaningful only in the framework of choosing the UTF size.</p>
<p>See Jitterbug 2150 and its discussion on the ICU mailing list in September 2002.</p>
<hr/>
<p><em>Obsolete part</em> of pre-ICU 2.4 <a class="el" href="utf_8h.html" title="C API: Code point macros.">utf.h</a> file documentation:</p>
<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. <a class="el" href="utf_8h.html" title="C API: Code point macros.">utf.h</a> 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 <a class="el" href="utf_8h.html" title="C API: Code point macros.">utf.h</a> 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, <a class="el" href="utf_8h.html" title="C API: Code point macros.">utf.h</a> 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><a class="el" href="utf_8h.html" title="C API: Code point macros.">utf.h</a> also defines a number of C macros for handling single Unicode code points and for using UTF Unicode strings. It includes <a class="el" href="utf8_8h.html" title="C API: 8-bit Unicode handling macros.">utf8.h</a>, <a class="el" href="utf16_8h.html" title="C API: 16-bit Unicode handling macros.">utf16.h</a>, and <a class="el" href="utf32_8h.html" title="C API: UTF-32 macros.">utf32.h</a> 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 <em>UNSAFE and _SAFE suffixes are aliased according to the UTF_SIZE to macros with UTF</em> 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 <em>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</em> prefixes need to be used.</p>
