Ah, I found this code in mule-cmds.el.

  (if (eq system-type 'darwin)
      ;; The file-name coding system on Darwin systems is always utf-8.
      (setq default-file-name-coding-system 'utf-8)

I don't remember why that code exists.  If the comment is
wrong (i.e. there's no need of treating darwin specially
here), the attached patch should solve the problem.  Please
try it.
