I recently discovered the compose key. It's wonderful to type Compose-> and get a Unicode right-arrow ().I know I can add my own, but where can I find a complete chart of the defaults?The largest list I could find is this one at freedesktop.org. However, it seems imperfect too: For example, it lists a combination ComposeFU as producing reversed hand with middle finger extended, whichquite disappointinglydoesn't work for meIs there somewhere these are stored on my actual live system?
Where are default compose-key bindings stored?
x11;compose key
You can find the compose table used by your system at the same place programs do: it's a text file. To locate it, you can run something likestrace xterm -e true 2>&1 | grep -i composeFor example, the relevant lines on Debian wheezy are:open(/home/gilles/.XCompose, O_RDONLY) = -1 ENOENT (No such file or directory)open(/usr/share/X11/locale/compose.dir, O_RDONLY) = 5open(/usr/share/X11/locale/en_US.UTF-8/Compose, O_RDONLY) = 5This demonstrates several things:To define your own table, put it in the file ~/.XCompose. Actually, you can override this location by setting the environment variable XCOMPOSEFILE.The location of the system table is listed in /usr/share/X11/locale/compose.dir. This file can list different tables for different locales. ComposeFU is a recent addition, the corresponding character is itself a recent addition to Unicode.
