Thierry Crozat 335ba979a2 LURE: Fix engine crash in copy protection screen with AZERTY keyboard 
Fixes bug #3539031 - "LURE: Crash at Copy Protection Screen".

This reverts the previous fix which only worked for QWERTY keyboards
and made the issue worse for AZERTY keyboards. It now uses the ASCII
code instead of the keycode for the sanity check.
