Title: Re: Mac Problems...

Eric,

Please try replacing the call to UpgradeScriptInfoToTextEncoding with the following code, and let me know if it helps:

   if (UpgradeScriptInfoToTextEncoding != 0)
    {
        status = UpgradeScriptInfoToTextEncoding(
            smSystemScript, kTextLanguageDontCare, kTextRegionDontCare,
            NULL, &systemTextEncoding);
    }
    else
        DebugStr(”\UpgradeScriptInfoToTextEncoding unsupported”);


-jdb
