Uuuggghh (to say the least).

Even more tricky.  I have an azerty keyboard.  To type '\' I press
alt-gr + '8'.  Qemu receives a '\' keysym, with altgr being pressed.
How do you know that that alt-gr is to be dropped (because it's an
artifact of the azerty keyboard) or kept as is (in the qwerty case one
may want to have an alt-gr + '\' shortcut)?
