Indeed, using "C" as my locale fixes the problem (I used to have
"LC_CTYPE=fr_FR").

Strangely enough, Emacs 21.4.1 with "LC_CTYPE=fr_FR" doesn't have the
problem (i.e., dead keys are usable).

Checking the "Meta Sends Escape" box of the xterm in which I run Emacs
22 also fixes the problem, even with a non-C locale.

I guess I'm just displaying my lack of familiarity with how terminals
work...

With a "C" locale, utf-8, latin-1, and others are accepted, whereas
`no-conversion' yields the above error message.

Thanks,
