sources for plane 2 characters?

[Thomas Chan]

Hi all,

I was looking at the plane 2 characters in the March 15, 2001 version of
the unihan.txt file, and found five that did not have an IRG source:
U+20957, U+221EC, U+22FDD, U+24FB9, and U+2A13A.  (The last one, U+2A13A,
however, has kIRGHanyuDaZidian and kIRGKangXi information showing that it
can be found in those dictionaries.  Still, shouldn't there be an IRG
source for it?)  Where are the first four from?

Thanks,


Thomas Chan
