-Xorg includes digraph support using a Compose key
-https://en.wikipedia.org/wiki/Compose_key#GNU.2FLinux .  
-The default of AltGr + Shift can be remapped to something easier such as
-Capslock. In GNOME2 2 and MATE this can be setup under
-Preferences → Keyboard → Layouts → Options → Position of Compose Key.  
-So, for example, to input »+« you could type CAPSLOCK > > + CAPSLOCK < <

-XCompose allows customising the digraph sequences using a .XCompose file and
-https://github.com/kragen/xcompose/blob/master/dotXCompose is an extremely
-complete one. In GNOME, XCompose was overridden and replaced with a
-hardcoded list, but it is possible to restore XCompose by setting
-GTK_IM_MODULE=xim in your environment. It might be necessary to install
-a xim bridge as well, such as uim-xim.
