Dear Lazyweb,

Recently my Compose key stopped working in applications using the X input method (such as rxvt-unicode). Gtk applications using either the default Gtk input method or SCIM work fine; setting GTK_IM_MODULE=xim breaks them. I have Option "XkbOptions" "compose:ralt,ctrl:nocaps" in /etc/X11/xorg.conf. xev correctly reports that Multi_key is being pressed when I push the right alt, but rxvt-unicode et al. totally ignore it when I push it at them.

I have no idea why this happens. I asked the #rxvt-unicode people, and they have no idea either. I would love someone to tell me what to examine next!

Edit (2007-10-10): Fixed!

It was all my fault. I had a .XCompose file with an entry for Compose-t-m giving ™, but did not have the magic line include "%L" which makes all the normal compose sequences for your locale be loaded. Thanks to Simon for helping me figure this out!
