You and I seem to be on amazingly similar paths. I got a copy of the
very same database file, and have converted it to a dBase version. I
have been writing a Visual Basic application to display the characters
side by side to check&correct errors. Using manual methods, I've
already found a few. Once I have the full application up an running, I
expect I'll find quite a few more.

My ultimate goal is to assemble a list of characters outside the current
Unicode set. Towards this end, the characters will be displayed in 3
columns, with CNS, CCCII and Unicode code points and glyphs from the
representative sets.

I've been working on this as a low priority project - just a couple of
hours a week....

Once I have the application written, would you be interested in a copy?
This would be a Win '95/NT application, and would use the stock bitmap
