Isn't a one-byte-long filename still a valid filename?  As far as I know,
as long as you can get a one-byte filename created, readdir will return
it, and `?' should match it.

I don't think Posix says that; it says that `?' matches `a character'.  If
you have a filename returned by readdir, and you're in a multibyte locale,
`?' will match a character, wide or not.

I was never able to get this to actually create a file, by the way, whether
or not I had specified a multibyte locale, using MacOS X.
