* In 99% of cases, the given key code is truly keyboard independent.

*
* Hungarian Keyboard: This is 'QWERTZ' and not 'QWERTY'.
* The '0' key is on the left of the '1' key, where '~' is on a US keyboard.
* A special 'i' letter key with acute is found on the right of the left shift key.
* On the hungarian keyboard, the 'i' key is at the left of the 'Y' key
* Some international keyboards have a corresponding key which would be at
* the left of the 'Z' key when using a QWERTY layout.
*
* The Apple Hungarian keyboard sends inverted key codes for the '0' and 'i' keys.
* When using the US keyboard layout, key codes are left as-is (inverted).
* When using the Hungarian keyboard layout, key codes are swapped (non-inverted).
* This means that when using the Hungarian keyboard layout with a US keyboard,
* the keys corresponding to '0' and 'i' will effectively be inverted.
*
* To fix the '0' and 'i' key inversion, we use the corresponding output character
* provided by OS X and check for a character to key code mismatch: for instance,
* when the output character is '0' for the key code corresponding to the 'i' key.
