Only Latin-1 based passwords are supported on the system at this point. As such, we need a way to show a Latin-1-compliant keyboard when unlocking the device. It is expected that 3rd party IMEs honor this mode for Latin-1 password dialogs. If not, this change will cause lockscreen to revert to using the Android system IME for entering the password.
