[boost] RFC: interest in Unicode codecs?

Dear Cory,

Your UTF standard conversion class looks very interesting.

It does however, not give access to the unicode data for grapheme or
glyph work.

I posted a full unicode character support library at
http://www.boostpro.com/vault/
unicode_lib.zip  

but Rogier and I ran out of time before completing the string class to
go with it.

If you feel up to it and want to develop a full Unicode support library
in addition to your codec, feel free !

Yours,

Graham Barnett
