We could recommend such users to install GNU regexp, which AFAIK
exposes the Posix API as well.

I assume you mean GNU regex. That project is long dead, and has been superseded by Gnulib. I would not recommend it for Emacs usage. See:


There's still the alternative which I asked about a couple of days

mbrtowc, I hope that's a viable option.

Yes, I've built that and am testing it. I plan to report back soon.
