Long ago NEWS.19 got this delightful entry:

** Dead-key and composite character processing is done in the standard
X11R6 manner (through the default "input method" using the
/usr/lib/X11/locale/*/Compose databases of key combinations).  I.e. if
it works in xterm, it should also work in emacs now.

This has long since stopped working.  I found a workaround of (require 
'iso-transl), which handles a few cases but not even a western European 
dead-cedilla is handled.  Even if I do (require 'ogonek), dead-ogonek is 
not handled.  All other programs still do this fine, why did Emacs 
forget about this?

Btw. this is Ubuntu 9.10 and the file name is 
/usr/*share*/X11/locale/*/Compose but I guess configure, which I ran 
from CVS should have detected that.

I don't use dead keys, but I use the compose key extensively, and it
works just fine in my Emacs.  Can you give more detail to try and
reproduce your problem?

what details, I don't really know.  It might be Ubuntu specific, because 
it appeared long ago when I switched from SuSE to Ubuntu.  At the time I 
figured it must have to do with a newer Emacs, because xterm and all Gtk 
and Qt apps had and have no problem.  Sorry I didn't report it then, I 
guess this is two years back.

I think compose is not pertinent, because IMHO that does the combining 
in the X-server and sends the combined char, as though you had a key for 
it, like German äöüß is no problem even without loading iso-transl.

I'm attaching my very personal keymap (which covers my normal German 
external keyboard, the built in American one, with Z and Y switched 
German style and Esperanto letters).  I've stuffed in all dead-keys, 
like AltGr-, for cedilla,  AltGr-Shift-, for ogonek and AltGr-^ for 
circumflex.  I load it with xkbcomp -xkb .X/keymap/daniel $DISPLAY, but 
you could just as well just set one dead key with xmodmap IIRC.

More information was requested, but none was given within 4 weeks, so
I'm closing this bug.  If this is still an issue, please reopen the bug
