The problem is that this method doesn't work for self-inserting characters,
i.e. to be able to handle keybindings that contain characters without
modifiers like e.g. `C-x b' we can't use

  (define-key input-decode-map [?β] [?b])

because it will translate all plain self-inserting characters,
and this is not desirable.

So users have to bother about rebinding all keybindings individually like

  (define-key input-decode-map [?\C-χ ?β] [?\C-x ?b])
  ...

I have no idea how to cover all keybindings automatically.
