We don't have an ibm942 conversion module and the ibm943 module was generated by
IBM.  I have no reason to believe the ICU tables more than those used to
generate the module.

I'll leave the bug open, maybe the module author will comment.  If this doesn't
happen I'll close it sometime soon.

You're right. iconv doesn't have ibm-942. I meant ibm-932. Sorry about that.

The ibm-* tables from ICU's charset repository are generated directly from IBM's
CDRA. I'm sure that the ibm943 iconv module was also generated from IBM, but
this seems to be a typo in the iconv module.

The main issue is not whether \u007F goes to \x7F or \x1C. Both mapping
behaviors are considered valid in IBM's CDRA. The problem is that those bytes
don't map back to the original Unicode character. You have to round trip convert
your data three times to get your original data back.

It's pointless to argue here.  Talk to the author of the modules.  I'm
suspending the bug until that happened.

Since I am unfamiliar with the authors of the module, where or who should I
really be reporting this problem to?

George Rhoten, you find the authors of the conversion modules in the glibc 
source files and ChangeLogs. For both iconvdata/ibm932.c and 
iconvdata/ibm943.c, it is Masahide Washizawa <washi@jp.ibm.com>.

I have contacted the writer of this code, and he has created a patch to fix the
code.

Quote from Masahide Washizawa, "I have just sent the patch to Ulrich-san who is 
the glibc maintainer, and he applied it to the glibc tree immediately."

So if the patch is applied, then I'm happy.

The patch was applied to the cvs.  I close it.
