Non ascii key inputs not dispatched

[tshirtman]

Present using the standard keyboard, at least in french and russian, inputing non-ascii keys in kivy doesn't work, a check in SDLSurfaceView (activating logs on onKeyUp and onKeyDown) shows that these keys never get to that point. This seems unrelated to the way the user inputs the keys, i use the same way to input "3" and "é" on the standard keyboard, by holding the "e" button and chosing among options, but "3" works, and "é" doesn't.
