MacOS QML TextField with Password echo mode allows non-ascii IME input

[jeffkim]

Hi. I recently ran into a strange problem while coding.( I am Korean)
QML TextField echoMode: TextInput.Password.

Windows platform not allows non-ascii IME input.
but MacOS platform allows non-ascii IME input.

why?
echoMode: TextInput.Password, is Properties Windows platform specific? Or am I missing a setting?

I hope MacOS platform not allows non-ascii IME input.
help me please...!

Window {
visible: true
width: 640
height: 480
title: "window"

Column {
width: parent.width
height: parent.height
spacing: 10

TextField {
id: test
echoMode: TextInput.Password
width: 200
}
Text {
id: test2
width: 200
text: test.text
}
}
}
