Some comments for you.

* In 1.1, rather than saying that Unicode occupies "two or more octets",
wouldn't it be better to say "21 bits - rather than the 7 bits of ASCII -"?

* Somewhere in the last two paragraphs of 1.1 you should be talking about
mini-languages (e.g. Cosmogol) as well as protocols and UIs.

* In 3, you're inconsistent between "U+NNN[N[N]]" and "NNN...". Indeed,
shouldn't the former actually be "U+[[N]N]NNNN"? (Note both the order and
the number of Ns.) I would suggest that better wording might be:

    ... U+NN syntax for code point references specified in the Unicode
    Standard, where NN is between four and six hexadecimal digits.

* In 4, second bullet, "string terminators" should be "string delimiters".

* In 5.2, you've said "generally considered ugly and awkward" but I'm not
aware of anyone else who's made that complaint.

* In 6 you need to copy in all the security stuff from Unicode; the stuff
that says that you must use shortest-form UTF-8 (so not using %xC1.A1 for
'A') because of the problems of filters and firewalls not spotting longer
forms.
