Certainly--that’s orthogonal to the issue at hand, though, it involves some
of the same things but is distinct. XEmacs could have implemented the
unibyte-string/multibyte-string Lisp distinction and kept the type
distinction between characters and integers; we didn’t, though. (Or maybe it
was just that the Mule version that we based our code on didn’t have it.)

As far as I can see it’s an old design decision.
