Yes, but the olpc version misses the non-english & non-dead-keys characters
as ñ,ß, etc. and with the image patch that works.

mmm, if you mean in the X libraries called by the vm, I think that's the
case. In fact that works that way whenever you use x2sqKeyInput instead of
x2sqKeyPlain at vm-display-X11/sqUnixX11.c. I.e.: if , calling the vm, you
use -nointl or your locale is not UTF-8, you'll use x2sqKey= x2sqKeyPlain
instead of x2sqKey= x2sqKeyInput, then you'll get the accent and the vowel
separated. Using x2sqKeyInput you will only get one keycode. That's worked
always that way, the problem was that the keycode was wrongly interpreted by
the image because it was using the MacRomanInputInterpreter instead of the

Having a new vm that does not work correctly typing non-english texts with
old and new images. With this change it will, at least, work typing using
