possible corrections to the unihan.txt database

As part of my CCCII project, I've been cross-checking the CNS<->CCCII
information in Christian Wittern's Kanjibase
(http://www.oas.hist.uni-goettingen.de/kbwww/kbQuery.htm) against a
similar table derived from the Unihan.txt database maintained on the
site(ftp://ftp.unicode.org/Public/MAPPINGS/EASTASIA/UNIHAN.TXT). I've
been walking down this table in CNS92 order, and the following lists are
from CNS plane 1. I will shortly have similar lists for CNS Planes 2 &

I would appreciate any input, to help further improve the accuracy of
both databases, and thus how well we can match up these diverse
character sets. It's very possible that the CNS or CCCII font files that
I have been using could contain errors that would foul up my analysis of
any discrepancies. For my work, I've been using the font files from the
following sites:

CNS: http://www.ifcss.org/ftp-pub/software/fonts/cns/hbf/
CCCII: ftp://nctuccca.edu.tw/Chinese/CCDB/

The following codepoints were missing CCCII entries in the Unihan.txt
database, but appeared to have valid CCCII matches

In the following codepoints, I decided to use the plane 1 equivalent
rather than the higher plane codepoint that was listed in the Unihan.txt

The following codepoints seem to have incorrect values in the CCCII
field. This could also be caused by my CCCII font file being incorrect.
