From: Tor Lillqvist Date: Wed, 13 Aug 2003 00:13:02 +0000 (+0000) Subject: Drop the Win32-specific implementation. It used WideCharToMultiByte(), X-Git-Tag: GLIB_2_3_0~86 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2b553df50de48b53cc0416ff6ce19f41d1a04320;p=platform%2Fupstream%2Fglib.git Drop the Win32-specific implementation. It used WideCharToMultiByte(), 2003-08-12 Tor Lillqvist * glib/gconvert.c (g_locale_from_utf8): Drop the Win32-specific implementation. It used WideCharToMultiByte(), which is broken as it stores unconvertable characters as fallback characters (question marks) in the destination string without being able to tell how much of the conversion succeeded. Using g_convert() like on Unix is better and simpler. (#117872) (g_locale_to_utf8): No need for the Win32-specific implementation here, either. (have_broken_filenames): Define as TRUE on Win32. (g_filename_to_utf8, g_filename_from_utf8): Drop Win32 ifdefs. As have_broken_filenames() now is defined TRUE on Win32, works as before. --- diff --git a/ChangeLog b/ChangeLog index 1b4ab66..d995209 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,21 @@ +2003-08-12 Tor Lillqvist + + * glib/gconvert.c (g_locale_from_utf8): Drop the Win32-specific + implementation.
