Doubts on KeyCode

[Benjamin Gudehus]

Hi,

"]" (ascii-code 93) from a native-keyevent to KeyCode happens in
Glass-Layer.

Hmm, the "+" key on a german keyboard layout [1] is actually "]" on the us
keyboard layout [2].

But when I type "+" on my german keyboard with german layout activated on
Windows it outputs "+" as unicode string and "PLUS" for the KeyCode. With
this code:

textField.setOnKeyPressed((event) -> {
    System.out.println(event.getText());
    System.out.println(event.getCode());
});
