Actually it's not really due to Unicode.  It's due to the fact that
Emacs Lisp doesn't clearly distinguish chars and bytes (and strings of
bytes and strings of chars) so we sometimes have to guess which one
is meant.

In practice it works surprisingly well, and lets most coders live their
life without having to know and understand the difference, but the
actual precise details are sometimes rather brittle because of its
DWIMish nature.
