Since these should be "displayed" by changing the direction of text, I think we can safely say that Emacs is not currently able to display them, so we should forcibly replace them by the usual boxes we use for chars that we can't display (usually it's because the font doesn't provide a glyph for it, here it's because Emacs doesn't know how to implement it).
