Testing on Windows Server 2003, I get 84 code points which wcstoi64
doesn't recognize but MAP_FOLDDIGITS manages to convert. These
include superscripts, subscripts, circled numbers etc., and Tamil.

The most interesting question is, what's wrong with Tamil? :(

Maybe we could use MAP_FOLDDIGITS anyway, but bug for bug, right?

And as for different Windows versions, my wctoint seems to be fine:
