Yes, exactly. It just happens in the case of Arabic that the contextual
glyph presentation forms *do* have Unicode code points of their own. But
that's not necessarily so for other languages (south Asian ones for
instance.) In the case of Arabic it's because of some compatibility
considerations, I believe.
