WideCharToMultiByte translates a unicode string to a multibyte encoding using
the specified code page, and then simple strcmp between the resulting string
and "e" will do what you need.

Wine uses tables auto-generated from the data provided by unicode.org,
the files are in libs/wine directory. Since the data in Wine and Windows
is from different sources there are quite a bit of differences in translations
between unicode and code pages.
