Commit log from Dragonfly:

FreeBSD extended ctypes to include numbers (e.g. isnumber()) but never actually implemented it. The isnumber() function was equivalent to the isdigit() function in every case. Now that DragonFly's ctype source files have number definitions, the number ctype can finally be implemented. It's given a new flag _CTYPE_N. The isalnum() and iswalnum() functions have been changed to use this flag rather than the _CTYPE_D digit flag. While isalnum(), isnumber(), and their wide equivalents now return different values in locale cases, the ishexnumber() and iswhexnumber() functions are unchanged. They are still aliases for isxdigit() and iswxdigit(). Also change ctype.h for isdigit and isxdigit to use sbistype like the other functions. Obtained from: dragonfly

Cleanup of xlocale:

2012-02-14T12:03:23Z

- Address performance regressions encountered by das@ by caching per-thread data in TLS where available. - Add a __NO_TLS flag to cdefs.h to indicate where not available. - Reorganise the xlocale.h definitions into xlocale/*.h so that they can be included from multiple places. - Export the POSIX2008 subset of xlocale when POSIX2008 says it should be exported, independently of whether xlocale.h is included. - Fix the bug where programs using ctype functions always assumed ASCII unless recompiled. - Fix some style(9) violations.

The problem is: currently our single byte ctype(3) functions are broken

for wide characters locales in the argument range >= 0x80 - they may return false positives. Example 1: for UTF-8 locale we currently have: iswspace(0xA0)==1 and isspace(0xA0)==1 (because iswspace() and isspace() are the same code) but must have iswspace(0xA0)==1 and isspace(0xA0)==0 (because there is no such character and all others in the range 0x80..0xff for the UTF-8 locale, it keeps ASCII only in the single byte range because our internal wchar_t representation for UTF-8 is UCS-4). Example 2: for all wide character locales isalpha(arg) when arg > 0xFF may return false positives (must be 0). (because iswalpha() and isalpha() are the same code) This change address this issue separating single byte and wide ctype and also fix iswascii() (currently iswascii() is broken for arguments > 0xFF). This change is 100% binary compatible with old binaries. Reviewied by: i18n@

which has been repo-copied from ctype.h. This will allow us to remove namespace pollution from and to make wcwidth() an inline function without introducing more pollution.
