Do you know if there is any configuration on AIX that would derive Cp943C as the default charset? That is, are they running with -Dfile.encoding=Cp943C on the AIX systems or is it chosen by default. This goes to the question as to whether they just moving these applications to Linux and expecting the default charset to be the same.

Do you know which APIs they are using? We filled in the gaps many releases ago so that all APIs that do encoding/decoding allow the charset to be specified and I'm wondering why they don't use those.
