Right. This is one concern that keeps coming up over here at Netscape.
At the Sevilla conference, Larry Masinter mentioned "transparent content
negotiation", where it is apparently possible for the client to first
indicate a willingness to negotiate, and the server could respond with a
list of choices, from which the client makes a choice.

This, however, requires another round-trip to the server and back, and
might be even more expensive than just sending all the charsets in the
first place.

How about using a more compact representation of Accept-Charset. E.g.
bit masks corresponding to the number in the charset registry. This
would omit the "q" parameter, but I'm not sure this is needed in the
Accept-Charset case anyway. (It's probably needed for Accept-Language.)

I don't think we should have UI for the Accept-Charset. Think about
novice users. Will they understand it?

Servers cannot send UTF-8 to clients unless they know that the client is
capable of decoding it or there is a large critical mass of browsers in
the installed base that is known to be capable of decoding UTF-8.
