Please keep `C-u' for its intended purpose, which is already quite general. A
command might well use a zero prefix arg value for a specific behavior, and that
command might be bound to anything (even `x').

It is not just because some key binding (e.g. `C-u 0 x') is not predefined that
it should be predefined for Unicode entry.

This thread got off the ground because some thought that using an input method
could be too heavy for inputting Unicode chars. OK, keep looking for a better
(non "input method") input method, if you must. But please stay away from key
chords and existing key bindings.
