I have no idea what the difference is between LoadLibrary, LoadLibraryA
and LoadLibraryW ...

I agree that the explicitely stating LoadLibraryA or LoadLibraryW
would be best.
But IMHO LoadLibraryA would be a bad idea. This would not allow to
load modules
located in pathes containing unicode characters.
IMHO interpreting the path as utf-8 and then converting it to wchar
would be better
and then trying LoadLibraryW(). If the path cannot be converted or
LoadLibraryW()
fails a second attempt can be made using the original argument of the
xmlModulePlatformOpen
function passed to LoadLibraryA(). For the utf-8 -> wchar thingy there
is already code
in xmlIO.c doing these things it should be recycled here.

Okay, I can't test this, someone comes with a complete patch and I can
review and apply it,
thanks,
Daniel
