Pardon my ignorance, but what is an astral character? I can't find a
definition on the Unicode site, and Google mostly comes up with hits that
seem to have to do with Tarot! (Does this confirm the long-held suspicion
that Macs run on magic? ;^)
Thanks!

Um, would those characters then dwell in the astral plane?
No question, a much more appealing term!
Thanks

There is no such thing as an astral character in Unicode or 10646.
But someone did suggest that as a name for non-BMP characters before
one settled on the term supplementary character.

The allusion to Tarot isn't entirely specious! Code Planes higher than the
BMP were referred to as higher planes... or astral planes. Therefore,
these Code planes were obviously populated with astral characters.
But I never did figure out if everything above Code Plane 16 was above or
still
Rick Cameron suggested:
Would it be useful to have one term for planes 1-16 and another for all
planes above the BMP? Perhaps the former are astral and the latter
celestial. ;^)
(I'm half-serious, since according to my suggestion UTF-16 can encode all
astral characters, but not all

As for the cats, in Up up up past the Russell Hotel, up up up to the Heaviside layer?
Actually, my surmise, given the fact that the code points past U+10 are
That's interesting - I had assumed that there was no maximum to the scalar
values in Unicode, just that each encoding had its limits.
In my copy of The Unicode Standard Version 3.0, I can't find an explicit
statement that scalar values in Unicode are only in the range U+0 to
U+10 - but this
The region beyond U+10 contains photos of the editors
