If my understanding of OS X is correct, then this won't work: OS X
demands UTF-8 for all file names.

The interesting question is whether u"fr\xf6r".encode("utf-8") allows
one to open the file. If that won't work, it could be considered a bug
in OS X, and I trust Apple that they can get such things right (if
they had considered them).

BTW, the same question holds on Windows: If you create a file on NTFS
with \xf6 in it, can you open it by passing \x6f\u0308? I can't try at
the moment...
