Key event in any language and shift+ctrl

[mehrdad]

i use this code for undo and redo functions in my program
@
if(event.modifiers && Qt.ControlModifier){
if(event.key=== Qt.Key_Z){
Undovar.unDo()
console.log(event.key)
}
if(event.key=== Qt.Key_Y){
Undovar.reDo()
}

                if(event.modifiers && Qt.ShiftModifier){
                    if(event.key=== Qt.Key_Z){
                        console.log("lose")
                    }
                }
            }@

a have 2 questions

1. some users(like me) might use second language and by this code, event keys just work for english...
2. in this code Qt.shiftModifire make no difference and in fact by pressing ctrl+z console print "lose", how can i fix it...
