Dear ABNF-Discuss (and rfc-interest):

This draft by Chris Newman and I addresses an interesting topic: how to 
do Unicode in ABNF. Unicode has showed up in several different ways in 
protocols that are described in ABNF. These ways are not consistent 
across the RFC series, but now that Unicode is a pretty stable standard 
(for its basic parts) and now that UTF-8 RFCs are becoming a reality per 
draft-iab-rfc-nonascii-02, it is a good time to look at this issue. This 
is a fork from draft-seantek-abnf-more-core-rules.

This draft is currently proposed as Experimental. Special thanks to Paul 
Kyzivat for discussing the matters in this draft, although he is not 
formally a co-author.

The draft tries to be very conservative in its approach. Please read the 
draft for details. Some stuff was intentionally omitted as out-of-scope 
or too complicated for a general-purpose ABNF syntax parser, whether 
humans or machines.

Comments and feedback are appreciated.
