See: 2.2. ABNF for IRI References and IRIs in: http://www.ietf.org/rfc/rfc3987.txt Misha -----Original Message----- From: ietf-bounces@xxxxxxxx [mailto:ietf-bounces@xxxxxxxx] On Behalf Of Tom.Petch Sent: 05 January 2006 20:15 To: James Seng Cc: ietf Subject: ABNF Re: Troubles with UTF-8 You say that a Unicode code point can be represented by %xABCD but that is not spelt out in ABNF [RFC4234]. And when it refers to 'one printable character' as '%x20-7E' I get the impressions that coded character sets like Unicode, with more than 256 code points, do not fall within its remit. I have yet to see any use of this in an I-D or RFC. I did post a question about this to this list on 24th December and the lack of response reinforces my view that this is uncharted territory.
