The value specified for the MailMessage.BodyEncoding property sets the character set field in the Content-Type header. The default character set is "us-ascii".
If you set the MailMessage.BodyEncoding property to System.Text.Encoding.UTF8, System.Text.Encoding.Unicode, or System.Text.Encoding.UTF32, the Framework selects a System.Net.Mime.TransferEncoding of System.Net.Mime.TransferEncoding.Base64 for this System.Net.Mail.MailMessage.
