OK, so "invalid" was up to Emacs 22, then?

So the problem is that because characters are integers and vice versa,
there's no way for the user to let Emacs duck-type multibyte vs
unibyte strings for him.  If he cares, he needs to check.  If he
doesn't care, eventually Emacs will punish him for his lapse.

I suppose subst-char-in-string is similarly useless for Alan's
purpose, then?  What he really needs to use is something like

    (replace-in-string str "\n" "ñ")

right?
