How come the filesystem decoding is set to ASCII?

Please do add these to the wiki, so we won't forget them. If you want
CYGWIN to work, existing CYGWIN users will have to contribute patches.

OK, so the fix may need to be backported -- or perhaps (if it's easier
to find and fix in 2.5) forward ported.
