I have quite a few custom compose key sequences. I know I can get them working with an ~/.XCompose and switching the input method to xim. However, Sublime Text 2 doesn't accept any compose key sequences when I'm using xim. It does accept them when I'm using the default input method. I think I reported this bug for Sublime Text 2 a while ago.
Using the default input method, I added the contents of my ~/.XCompose to /usr/share/X11/locale/en_US.UTF-8/Compose but this did not change anything. Is there any way I can get the compose key sequences in my ~/.XCompose to work without relying on xim?
