I don't understand this, the arabic non characters

no, they are unrelated and additional.

I understand now.. the non characters in 16 higher
planes were defined first, then the ones in the arabic
in them? At least 17 planes
must be defined in order to define the 32 non
characters in 16 supplementary planes, thats what
common sense would say anyway.
This whole plane business suffers from a lack of
documentation. UAX #27 talks about planes as if its
ancient history but the Unicode 3.0
Some brief and not complete answers follow.
I'm trying to get a grasp on exactly how many planes
are defined in Unicode
[...]
How many planes are defined in Unicode 3.1?
There are 17 planes, and everything will be re-written to reflect that,
eventually. Most of the planes are empty
. The planes themselves
have been here since 2.0.

mention planes once (its not in the index anyway). I
would like the Unicode documentation
