Ah.  Now I get it.  But still think that CJKV encoding follows
the conventions used for other scripts.  First come, first served.
When new Latin characters are proposed, there's no effort made
to determine if they are rare or obsolete to see if they should
go into Plane One rather than the BMP.

With CJK, the addition of Extension A was put in the BMP because
there was room for it, among other reasons.  There wasn't room for
Extension B, though.

Anyway, I think we can all agree that, for the subject of this
thread, any application supporting Unicode CJKV will need to
support the higher planes.
