Unicode events?

Hello,

Some braille devices may be used as input devices, and some of them don't have a PC-like keyboard, but a braille keyboard: when pressing dot 1, 'a' should be output. Currently, there is no way to do this with the input layer: if we generate KEY_A, then that will be right for qwerty keyboards, but not for non-qwerty keyboards. Then I'm wondering:
shouldn't we add a unicode event type, which will just hold the unicode character that should happen?
