The converters for Cp942 and Cp942C (Japanese IBM PC) have a number of problems
dealing with the "ITAIJI" characters.

The broken conversions, and the corrections, are as follows:

I'm filing this bug on behalf of IBM Japan's DBCS group. Since
I don't really know that much about these issues myself, feel free
to contact Masayuki Fuse at <###@###.###> for more info.
