The keyword here is "sort of".  And of course, the behavior was
different in Emacs-22, yet most/all of this code dates back to before
Emacs-23, so that makes it even more murky.

Conversions between bytes ("unibyte") and characters ("multibyte")
should be done by encoding/decoding.  Using terms like "converting from
unibyte to multibyte" just messes up with your head to make sure you
can't think straight.
