Right.  I have found it very annoying to find that I can cut&paste
unicode strings from Emacs to galeon, but get only ? when doing it the
other way round.

What's the state of it?  Am I right in assuming that we would first
be releasing a full-featured 21.4 (or, if really necessary, another
bug fix 21.4 followed by a full 21.5)?  In that case, probably
another bug fix 21.xx series would have to follow, and one would
probably make something like 22.0 the goal for a Unicode Emacs, with
probably some alpha versions before that?

Sorry to be using the "R" word here.
