Backtracking a bit here, why would this break anything? For
strings coming out of the Win32 API, immediately decode them to
characters; for strings going in, upgrade them to characters if
necessary, then encode them to ANSI at the last moment.

That way, no one ever needs to care that filenames are in ANSI,
because as far as Perl code is concerned it always gets them as
character strings.
