Yes, but composed characters don't work on character-based terminal in
the first place... (At least not in my environment).

Not if the cursor changes its shape. But I suggest that we will stay

Tibetan, etc.)

It seems that forward/backward commands are working per-base
character, while delete is done per diacritical.
