we need make this platform dependent.
in windows, the directionality of string is determined by UI's directionality,
so above is working.
in linux (chromeos too), the directionality of string is determined by its first
strong directionality character's direction. so above wont work.

Or we use model_->render_text()->GetTextDirection()
