If you assume you've got mostly posix then it's not too bad is it?

You actually get utf8 or whatever matching already if you "setlocale"
into such a charset.  A bit of a trap if your strings are in one
charset and it's being interpreted in another.

The perl way has its fans.  I guess an add-on that let you get that
instead or as well as the basic posix bits might be cute.

It might have to be LGPL to maintain that status on the resulting
program.
