That is more than I expected to change in emacs-29, but we could do that too if 
you like.

Since the input is UTF-8 the result, with the patch, will always be either a 
multibyte string or a unibyte ASCII string. Always making a multibyte string 
would also do and be marginally faster, but not more correct in any meaningful 
way.
