Defines the *term* UTF-8, although it doesn't define the bit mapping for
the encoding form.

And Doug is correct that we don't currently have a summary discussion
of how UTF-8 works. This is an oversight that ought to be addressed
on the website.

See Definition D36, page 47, Section 3.8 Transformations, in the Unicode
Standard, Version 3.0. Accompanying that definition is Table 3-1, which
shows the UTF-8 bit distribution in detail.

I agree.
