I'm really a fool regarding Unicode/UTFx issues, however, some things I noted
are below:

a UTF-8 character may (sometimes) be even 16bit of size; think about german
umlauts, they get escaped somehow, and then follows the code for them.

This really can't work either. Did you get this compile? You obviousely
copy'n'paste-ed your 16/32-Char classes from the Utf8Char class and didn't
change the constructor (btw).
Sorry for not being much help more, but you could/shoult google for "encoding"
and have a look around for some other implementations / how they're doing it
(the en[/de]coding-way).
