I'll claim that this (html-wg) is the wrong forum for discussing this
issue. HTML can and should accept URIs as they are defined elsewhere,
and say as little about them as possible. However, the
character-set-in-URI issue was discussed ad nauseum in the URI working
group, and pot-shots should not be taken lightly.
I think the HTML 3.0 draft might want to resynchronize with the 2.0
draft on the language around character sets once 2.0 is out the door.
