    Note the passive voice. ;) If you haven't seen the need, you haven't
    been looking in the right places. Keyboard protocols for Arabic are
    commonly and properly ridiculed by Arabic users.

    Can you please expand on this a bit? It doesn't seem to me like it
    would be any different that any other new character; well-designed
    Unicode-enabled software should be able to handle it with minimal
    changes, if any, I would think. And why would existing data become
    obsolete if new codepoints are added? The meaning of existing
    codepoints need not change.
