Hey internals

I recently saw a comment on Reddit about the lack of a multibyte version of ucfirst and lcfirst.
I was surprised to see this is indeed the case.
I also checked the modes of mb_convert_case: the closest supported one is title case, but there's no mode for only handling the first letter.

I have two questions (and some sub-questions):
Does anyone know if there is a historical reason for this? A quick search on externals.io didn't provide something useful.
Do you think this is useful? If yes, do you think this should be part of mb_convert_case or should this be a standalone function?

Kind regards
Niels

I think it would be useful.
For some reason, lots of people on stackoverflow has a hard time
implementing this function in userland:
on https://stackoverflow.com/questions/2517947/ucfirst-function-for-multibyte-character-encodings
there are 10 broken implementations of mb_ucfirst, and 1 correct one
(disclaimer: I only consider my own implementation correct:
https://stackoverflow.com/a/58915632/1067003
and consider every other implementation on the list broken in one way
or another. and i was really surprised that nobody else got it right.)
