This may be system related and not Pegasus Mail related but since it manifests itself in Pegasus Mail I thought it worth tapping this wealth of knowledge for assistance.
I have a customer service rep with a California based company who sends plain text messages using a Korean character set specified in the headers: Content-Type: text/plain; charset="ks_c_5601-1987". These messages display with Korean characters when viewed by any user running the shared office installation of Pegasus Mail but the same message displays in English when viewed using both my laptop and my flash drive installs of Pegasus Mail. FWIW, tmy flash drive install runs on the same PC as my shared office install. The only things I know to check are the system locale (all are English(United States)), and the default MIME setting within Pegasus Mail (all are ISO-8859-1). Please post any thoughts you may have for an explanation/fix for the Korean display.
Thanks.
