Aspose.email - message body

Hi,
We are using ASPOSE.EMAIL to send mail.
Whatever mail content we sent, we capture in database.
Next time when user wants to reply we retrieve from database and allow user to send reply through BPM UI.
What we noticed here, there are additional characters(non-ascii characters) getting stored in database. We tried using encoding utf-8 and ISO-8859-1. Its not working. Any help.

E.g
