Of course. Thanks, Paul. That makes perfect sense and I can forget all
about it from a font perspective. Good. Roozbeh had me confused by asking
whether fonts would be able to handle this 'worst thing in Unicode'; I
should have realised that it isn't a font issue.
Can I ask what Uniscribe would do if it encountered Roozbeh's ZWJ+ZWNJ+ZJW
character string? Perhaps it would help if Roozbeh explained why he sees
this as a problem.

Type is something that you can pick up and hold in your hand.
