I'm afraid it's slightly more complicated than this. Older Windows
versions (Win9x, WinNT 4.0) use different default codepage (charset) for
console windows and for GUI ("OEM" versus "ANSI" codepages). Newer
versions (Win2k+) use always the "ANSI" codepages (i.e. 1251 for Russian,
1250 for Central Europe, 1252 for Western Europe). No idea what WinME
does. Anyway, you have to check the Windows version first...
