So I tried using Unity's "Input.imeCompositionMode = IMECompositionMode.Off;" to disable the use of ime keyboard, but it still lets me type in korean characters into the text input field. I even made a custom validator to return a null character if the user types while Input.imeIsSelected is set to true. That helped a little as now it prevents any korean characters from being added after the first character. The issue is that it can't seem to stop the first korean character from appearing. Anyone encounter this issue before?
