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?
