No, X11's XKB doesn't support multiple-keysyms per level. The solution
up to now is to either use pre-composed unicode codepoints (which is not
always possible), or to use the Compose mechanism.
But Compose should work generally, the only problem here that I know of
is GTK not using the user's Compose file by default; but that can be
fixed by setting GTK_IM_MODULE=xim. I know Qt5 uses the system's Compose
files, not sure about older Qt's.
Did you run into any problems with this approach?
