[Python-Dev] PEP 277 (unicode filenames): please review

But if you pass the normalized string (or the Latin-1 string) to
open(), will it find the file?  I.e. if the filesystem has the
unnormalized name stored in its directory, will filesystem requests
normalize filenames before comparing them?

Jack, can you try to do that?  Can you try open('fr\xf6r') in that
directory?
