Oh yes, you're correct :-)

Not an exotic keymap, but an exotic keyboard that has 60,000+ keys ;-)
Anyway, this is probably technically an excellent thing to do, but from
usability POV it can be bad for CJK users (even if it can be implemented).
The most efficient way for activating items is Alt plus a single keystroke,
needing multiple keystrokes will reduce the efficiency. The problem is
tied to the hardware (keyboard) instead of bug #104112 for CJK users,
and I don't think too much can be done except stripping extra mnemonic
keys and parenthesis.

However, for other languages, I'm not sure at all, so others can shed
some light on it.

I see. Something like "gl_[u]Ãcklich", so pressing alt-u can activate the
item?
