> Emacs should never use unibyte strings for buffer names.

I don't think we make any effort to prevent this from happening.

And I'm not completely sure that it would be worth the trouble either:
I suspect that wherever a unibyte buffer-name would cause problem
(mode-line, window title, younameit), some other unibyte string could
appear from elsewhere just as well, so enforcing multibyte buffer-names
wouldn't close the vulnerabilities.
