The unihan.txt file ver 3.0b1 (1999.7.2) lists four K- sources as:
K0 KS C 5601-1987
K1 KS C 5657-1991
K2 PKS C 5700-1 1994
K3 PKS C 5700-2 1994
It's very clear what K0 and K1 are, and they are given as GR ranges
arranged by pronunciation, and it is okay that these ranges overlap, since
K0 and K1 are two different character sets.
K2 has what appears to be GL ranges given for it (0x2121 .. 0x7530), and
arranged by radical+strokes. K3 looks similar, having what appear to be
GL ranges (0x2121 .. 0x3771), arranged by radical+strokes, but they all
fall within CJK Extension A. The ranges given for K2 and K3 also overlap.
(They seem reminiscent of the "planes" of CNS 11643 / EUC-TW .)
According to the 02n34428_cjk_b_fcd_mapping.txt file (May 2000?), the
K source (#4?) is given as a decimal number from 0002 .. 0269, arranged by
radical+strokes, and all within CJK Extension B (but this file only deals
with Ext B, so that doesn't mean much). There seem to be some gaps in the
numbering, though. I'm not sure what to make of this in relation to K2
and K3, or the whole "PKS C 5700" thing. The later date (1998 vs. 1994)
must also be of some significance.
