New composers for local languages in Togo

[Mats Blakstad]

There do not exist any precomposed character for these once.

Does it mean that it is impossible to add these composers for XKB keyboards?

That's really a big pitty!

I could of course suggest for unicde to add them as precomposed
charahcters, but would it not be much more easy if XKB could handle
combinations too? Then we don't need to create new unicde characters every
time we want to add a new combinations of tones..
