The reason we explicitly chose to have a keysym (really, 'Unicode
codepoint') event, is to support characters which don't appear in any
keymap. As a trivial example, emoji keyboards will want to send
symbols which appear in no sane keymap. Similarly, CJK input methods
may offer streams of characters pre-composed from component runs; it
is not practical to insert the entire CJK unicode space into a keymap.

Cheers,
Daniel
