When pressing CTRL+SHIFT+number on a German keyboard then the key() you get in the key press is not always as expected

When pressing CTRL+SHIFT+number on a German keyboard then the key() you get in the key press is not always as expected. For instance in the example if you press CTRL+SHIFT+2 then you get @ as the key(). Whereas there does not seem to be any indication that @ should be sent. It should be " instead as that is SHIFT+2 since there is no special key to display here like with Norwegian keyboards. This seems to be caused by an incorrect fallback or something like that from having a first glance at the code in question.
