My guess is that his `file-name-coding-system` is set to something
different from utf-8.
[ BTW, I wouldn't be surprised to hear that the Freedesktop spec
  documents that the file names in the Trash should use utf-8, in which
  case the code should hard-code utf-8 rather than use
  `file-name-coding-system` ;-)  ]

Tho only for reasonably trivial amounts of "working on that" ;-)
