Hi Matthews,
About 10 years ago we had to reconfigure the MFC client and PDF SSO to handle French Canadian.
In MFC session properties Regional Settings are set to ProivRes_English_UK.dll with the Server Code Page set to "28591 (ISO 8859-1 Latin I)".
In the ProIV .ini file we have JAVA_STRING_CHARSET=ISO8859-1.
With these settings we are able to handle French characters in ProIV logic and display them in statics. We are also able to create PDF's in French.
I hope this helps.
Regards
Ross
