It seems that I have something funny in utf8.h after then 7F here,
so you may see something funny, too...
The reason why C0-C1 is missing here after 7F is that the above table
also suppresses overlong UTF-8 sequences.
See
http://www.cl.cam.ac.uk/~mgk25/unicode.html#utf-8
for a list of all bit patterns that have to be excluded to avoid
overlong UTF-8 sequences.
