Based on the language code, to be exact, and this is an *implementation detail(tm)*:


        return switch (locale.getLanguage()) {
            case "ar", "fa", "he", "iw", "ji", "ur", "yi" -> RIGHT_TO_LEFT;
            default -> LEFT_TO_RIGHT;
        };


so we'd need to invent something similar.  And even though we currently provide zero support for vertical text input or orientation, this might change in the future, at least an argument can be made from the API completeness perspective.

we also need to listen for input language changes at run time.
