Point taken, but not convinced. For all practical purposes, UTF-8 is defined by
RFC 3629. That's where people look. Also, RFC 3629 doesn't even link to another
definition. So where is the definition by the Unicode consortium, and why isn't
it referenced?

Also, a more general point: I would hope that all future definitions of
character encoding schemes in the IANA registry are based on the Unicode code
points, even those which can not represent all code points. The procedure for
IANA charset registrations is in IETF BCP 19, which doesn't even mention
Unicode, as far as I can tell.
