Thanks. One followup - in the Win32 case (where I guess we can still use
the normal getDirectoryContents and get a FilePath), is it still
necessary to re-encode the results to guarantee independence from the
current settings (e.g. as proposed by Max in
http://www.haskell.org/pipermail/glasgow-haskell-users/2011-November/021116.html),
or do we just always get the original filename properly because of the
way Windows handles paths?

Sorry if all this is obvious but every time I think I understand Unicode
I get proven wrong!
