2002-11-08Add wcwidth and wcswidth, based on Markus Kuhn's wcwidth of 2002-05-08.Manuel Novoa III
Added some size/speed optimizations and integrated it into my locale framework. Minimally tested at the moment, but the stub C-locale version (which most people would probably be using) should be fine.
2002-11-05Forgot to change btowc and wctob when I changed the wc<->mb functions yesterday.Manuel Novoa III
2002-11-04Add printf wchar support for %lc (%C) and %ls (%S).Manuel Novoa III
Require printf format strings to be valid multibyte strings beginning and ending in their initial shift state, as per the stds. Fixed a bug in _wchar_wcsntoutf8s(). Don't store wcs position if dst is NULL. Also, introduce an awful hack into _wchar_wcsntoutf8s() and wcsrtombs() in order to support %ls in printf. See comments below for details. Change behaviour of wc<->mb functions when in the C locale. Now they do a 1-1 map for the range 0x80-UCHAR_MAX. This is for backwards compatibility and consistency with the stds requirements that a printf format string by a valid multibyte string beginning and ending in it's initial shift state.
2002-09-19Hide my personal #warning reminders. Add __wcschrnul, rename strchrnulManuel Novoa III
to __strchrnul, and add weak aliases for them.
2002-08-12Revert commit by davidm to printf.c that initialized conv_numManuel Novoa III
needlessly. To do so increases the generated code size with bcc. Eliminate duplicate define warnings in wstring.c. Fix potentially broken preprocessor comparisons. The preprocessor converts integers to maximal signed type, so inequality comparisons involving UINTMAX_MAX, ULLONG_MAX, and (if no long long) ULONG_MAX were potentially broken.

wchar.c wouldn't compile: wchar.c: In function `__mbsnrtowcs': wchar.c:631: `__ctype_encoding_7_bit' undeclared (first use in this function) This fixes it by keeping the locale specific asserts hidden when not relevant. -Erik
2002-07-05Add copyright message and remove dead code.Manuel Novoa III
2002-07-03Enable WCHAR support for C/POSIX stub locales.Manuel Novoa III
Implemented unformatted wide i/o functions. (ungetwc still needs testing) Fix a few bugs in wchar.c. Modifications for bcc/elks support.
2002-05-23Multibyte and wide char conversion functions. Some work still to do, butManuel Novoa III
they're quite solid now and Erik needs them for the gcc port. Comments at the head of wchar.c.
