Instead of using a scan code, which for scan code set 2 will not represent the expected character mapping index, we could just use another variable in the KeyEvent structure that correctly points to the character index. This change is mostly relevant to the KeyboardMapper application, and also to the WindowServer code, as both handle KeyEvents and need to use the character mapping index in various situations.
