Ah, well. In `dbus-unescape-from-identifier', there is

     (lambda (x) (format "%c" (string-to-number (substring x 1) 16)))

If I replace it by

     (lambda (x) (byte-to-string (string-to-number (substring x 1) 16)))

everything works fine.

The following form evals to nil:

  (string-equal "\377" "ÿ")

The character code of "ÿ" is

Char: ÿ (255, #o377, #xff, file ...) point=244 of 5726 (4%) column=23
