The problem I reported is indeed fixed. However, there is still a
minor problem:

    (let ((default-directory temporary-file-directory)
          (file "pöytä-1.txt"))
      (with-temp-file file (insert "test file"))
      (file-name-completion file default-directory))
    ;; => "pöytä-1.txt"

According to documentation, file-name-completion should return t,
because there is only one possible completion:
    
    (directory-files temporary-file-directory nil "pöytä-1")
    ;; => ("pöytä-1.txt")

If there are no non-ascii characters in file name, everything
works fine:

    (let ((default-directory temporary-file-directory)
          (file "poyta-1.txt"))
      (with-temp-file file (insert "test file"))
      (file-name-completion file default-directory))
    ;; => t

This happens with GNU Emacs 23.0.60.10 (i686-pc-linux-gnu, GTK+
Version 2.12.9) of 2008-04-28 on arirop
