They introduced - • a type ‘wchar_t’, designed to encapsulate an entire character, - • a “wide string” type ‘wchar_t *’, and - • functions declared in ‘’ that were meant to supplant the - ones in ‘’. - - Unfortunately, this API and its implementation has numerous problems: - - • On AIX and Windows platforms, ‘wchar_t’ is a 16-bit type. This - means that it can never accommodate an entire Unicode character. - Either the ‘wchar_t *’ strings are limited to characters in UCS-2 - (the “Basic Multilingual Plane” of Unicode), or — if ‘wchar_t *’ - strings are encoded in UTF-16 — a ‘wchar_t’ represents only half of - a character in the worst case, making the ‘’ functions - pointless. - - • On Solaris and FreeBSD, the ‘wchar_t’ encoding is locale dependent - and undocumented. This means, if you want to know any property of - a ‘wchar_t’ character, other than the properties defined by - ‘’ — such as whether it’s a dash, currency symbol, - paragraph separator, or similar —, you have to convert it to ‘char - *’ encoding first, by use of the function ‘wctomb’. - - • When you read a stream of wide characters, through the functions - ‘fgetwc’ and ‘fgetws’, and when the input stream/file is not in the - expected encoding, you have no way to determine the invalid byte - sequence and do some corrective action. If you use these - functions, your program becomes “garbage in - more garbage out” or - “garbage in - abort”. - - As a consequence, it is better to use multibyte strings, as explained -in the previous section. Such multibyte strings can bypass limitations -of the ‘wchar_t’ type, if you use functions defined in gnulib and -libunistring for text processing. They can also faithfully transport -malformed characters that were present in the input, without requiring -the program to produce garbage or abort. - - -File: libunistring.info, Node: Unicode strings, Prev: The wchar_t mess, Up: Introduction +File: libunistring.info, Node: Unicode strings, Prev: char * strings, Up: Introduction -1.7 Unicode strings +1.6 Unicode strings =================== libunistring supports Unicode strings in three representations: @@ -572,6 +566,15 @@ File: libunistring.info, Node: unitypes.h, Next: unistr.h, Prev: Conventions, This type represents a single Unicode character, outside of an UTF-32 string. + The types ‘ucs4_t’ and ‘uint32_t’ happen to be identical.
