Does anyone understand what these are doing and (in a general sense) what the changes to Vista are?
When you specify the MAP_FOLDCZONE flag, FoldStringW() on Vista will try to return a "simple" presentation for the Unicode characters. For example, if you pass in 0x01c7 ("LATIN CAPITAL LETTER LJ", L and J combined into a single Unicode character, see http://www.fileformat.info/info/unicode/char/01c7/index.htm) then FoldStringW() will return two characters: the letter L (0x004c) and the letter J (0x004a). Versions prior to Vista simply returned the exact same code that you passed in for all codes < 0xf900. Flag MAP_EXPAND_LIGATURES does something similar for ligatures.
I suppose the main questions to ask are: 1/ are there applications that depend on the pre-Vista locale rules? 2/ are the Linux/*BSD/Mac/OpenSolaris (or glibc, uLibc, ...) locale rules *compatible* with Windows?
I haven't seen anything on the locale changes for Vista breaking anything except the Wine tests. As a result, it should (in theory) be possible to use the native version. This would then remove the need for Wine to copy the Microsoft locale tables.
Right. But that wouldn't fix the current tests.
