This is exactly what libutf does. It's not a Unicode library in the
form I described; it's just a workaround for broken systems lacking
UTF-8 locales, for which it replaces all the important functions
(mb*towc and wc*tomb, etc.) with versions that convert UTF-8. I
believe it also replaces the is* and to* functions and maybe a few
others. But it doesn't help with any Unicode processing needs the
application might have outside the scope of C or POSIX, and it's not
meant to be used on systems that already have proper UTF-8 support at
the system library level.
