No, but f6 is. The escape sequence is always of the form
ESC[0;xxA where xx is a codepoint. (I don't know if it's more
than two hex digits wide for characters with higher codepoints.)
Likewise I get ESC[0;e4A for ä and ESC[0;fcA for ü, where e4 and
fc are indeed the correct Unicode CPs for these characters.

I use a modified US layout where AltGr-; produces a dead
diaeresis, which a following keypress onto an applicable
character such as a vowel turns into an emitted umlaut. That
works perfectly well in xterm, Firefox and a large array of Gtk
apps including gvim.
Does that satisfy the requirement?

Okay, so I'd need to use a UTF-8 locale or a Latin1 locale, like
de_DE. Correct?
(Question: how do I set up locales such that it only affects the
character encoding programs use, but nothing else such as their
messages, numeric/currency formats or what have you?)

Does that imply that I need to change the X server's locale too,
or is it enough to set the correct locale for urxvt?

This here is a glibc-based Linux system (Slackware 10.0, FWIW).
Any pointers on what I need?

Good question. I simply did ``LC_ALL=de_DE LANG=de_DE urxvt''
(and two variations with only one of the variables each) and
received the aforementioned message.
What might be missing? What might I be missing?
I realize this whole issue is probably only tangentially related
to urxvt. Do you have any pointers on where I can read up on how
the whole locale thing is really supposed to work on Unix in
generally and glibc-based systems in particular? Good, accessible
documentation on these mechanisms is almost as elusive as a
thorough guide on how the termcap shebang really works.
Consequently, I've mostly used cargoculted configuration advice
and avoided the whole area as well as I could once things seemed
to work reasonably well. I have no idea what I'm really doing.
