True, there are a lot of information on character properties etc in
unicode. Some of that info can be found in other ISO standards such as=20
ISO 14651 on sorting and ISO TR 14652 with an enhanced POSIX like=20
locales.

What I meant is that the character table that defines the charset
in IETF terms, is almost the same, and the UTF-8 spec is almost the
same, and these are the specs that we probably will be using in=20
our enhanced mail spec.
