Unibyte strings should not be used for anything but pre-decoding /
post-encoding situations directly after / before doing the actual I/O
operation.  Thus substitute-command-keys should never be called with an
undecoded unibyte string.  IMHO it would be ok to return something
useless in this case (but it shouldn't cause Emacs to crash, of course).
