 * \file
 * \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.
 *
 * 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>
 *
 * Obsolete part of pre-ICU 2.4 utf.h file documentation:
 *
 * 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.
 *
 * 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.
 *
 * 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.
 *
 * 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.
 *
 * 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_...
 *
 * 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. 
 * 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.
 *
 * 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.
 *
 * 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.
 *
 * 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.
 *
 * <hr>
 *
 * Deprecated ICU 2.4. Use the macros in utf.h, utf16.h, utf8.h instead.
