Yes our replacement function in df is simplistic,
and doesn't deal with all encodings. See:
http://git.sv.gnu.org/cgit/coreutils.git/commit/?id=v8.17-51-g3ed70fd

Now the fact that you have both types of replacement chars
� (from mbsalign) and ? (from df),
suggests there is some mismatch in encodings.

What is the value of $LC_ALL and $LANG on your system?
What encoding is the file on disk? I presume some variant of ISO-2022-KR,
though I couldn't correlate that with the above output.
The encoding of the file on disk should be indicated by:
  LC_ALL=C gls --quoting=shell-escape -1 /Volumes

If it was possible to use UTF-8 representation of /Volumes/무제
then it would be displayed without issue.
