Hi, Given the fact that
"Rule names are case insensitive." http://tools.ietf.org/html/rfc5234#section-2.1 it could potentially be better to rename the rule from "utf8-char" to something else, since it may get confused with "UTF8-char" rule from http://tools.ietf.org/html/rfc3629#section-4. Taken into account my comments in the mail below, we could have new rule replacing utf8-char: zip-UTF8-char = UTF8-2 / UTF8-3 / UTF8-4 UTF8-2 = %xC2-DF UTF8-tail UTF8-3 = %xE0 %xA0-BF UTF8-tail / %xE1-EC 2( UTF8-tail ) / %xED %x80-9F UTF8-tail / %xEE-EF 2( UTF8-tail ) UTF8-4 = %xF0 %x90-BF 2( UTF8-tail ) / %xF1-F3 3( UTF8-tail ) / %xF4 %x80-8F 2( UTF8-tail ) UTF8-tail = %x80-BF The problem may be with the allowed ranges of the Unicode characters. The above grammar seems to allow 0080-10FFFF (the UTF-16 accessible range minus characters < 0080) http://tools.ietf.org/html/rfc3629#section-3 whereas the current utf8-char rule is more selective. Thanks.

This would probably disambiguate the P&C spec and may result in Widgets 1.0: URI Scheme's widget-URI being correct. Thanks.
