I was more or less idly curious; I don't care how they choose to fill it.
My understanding is that they could put in about 10,000 with a minimum of
Getting full coverage of the characters in KangXi, the non-unifiable characters
in CNS, CCCII, and EACC, and various archaic characters now being identified by
groups in the US and China would proably bring in about 20,000 to 30,000 total,
at a guess.
If one accepts 80,000 as a realistic figure for the number of Han ideographs
used through the ages -- and some, our own Lee Collins among them, would debate
that number, one extra plane would be just about right.
And, if advocates of a sparse encoding carry the day, the plane might be filled
before we actually have enough characters to fill it, if you catch my drift.
