on the MacOS platform QML TextField with Password echo mode allows non-ascii(korea lanaguage) IME input

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

Windows platform not allows non-ascii(korea lanaguage) IME input.
but MacOS platform allows non-ascii(korea lanaguage) IME input.

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

I hope from MacOS platform not allows non-ascii IME input.

help me please...! Thanks you.
