As my $0.02, it is likely best not to create yet another
re-implementation.  There's already precedent for including dependencies
that can do a very complex job well, like GMP and MPFR.

Text handling is deceivingly simple, and in practice, nobody seems to
get it fully right.  The effort is minimized, and yet most effectively
shared, if done in a library.

(note: I don't have a horse in the race wrt which specific library to
use, as I'm no expert, but I suspect libunistring could work well)

Have a wonderful day!
