This string is by definition multibyte at that point, since that part of
the code is inserting a Unicode character that is not ASCII.
More generally, Fsubstitute_command_keys is quite confused about unibyte
versus multibyte issues. It merges together a number of strings, and
assumes that they are all multibyte iff the original string is
multibyte, which is obviously not true in general. (This problem is not
limited to the requoting part of the code.) In master, I've altered the
implementation to always generate either the original string, or an
ASCII string, or a multibyte string. Since substitute-command-keys is
not intended to be used on encoded unibyte text, that's good enough.
