Does the user have an IME keyboard input source selected?
Note: This API is part of the legacy Input
class, and not recommended for new projects. The documentation is provided here to support legacy projects that use the old Input Manager and Input class. For new projects you should use the newer and Input System Package. (read more).
This returns true if the users keyboard is currently configured for IME input, and false otherwise.
Since users of asian languages can typically turn IME conversion on or off using a keystroke, it is useful
to provide some visual indication of IME being enabled. This can be done by checking Input.imeIsSelected.
