Hm, most of them do not match the specification much, I think it fixed them,
but I don't know if they will still work for you.

Changed to return partial string instead of failing if buffer too small.

Should just be a simplification.

Changed to return the number of bytes copied instead of an error for LOCALE_IDEFAULTANSICODEPAGE
and to return an error for all other cases (also handling too small buffer and cchData == 0
cases).
I'm almost certain this won't work anymore, but who knows.
