Not sure why you say "but" here: I was also talking abut a multibyte
string, so I obviously agree.

I'm not sure where you read that I was arguing we shouldn't support
this scenario.  I was just pointing out that utf-8-emacs-unix is not the
only thing that makes sense: string-to-unibyte should work just as well
(if not better).
