I'm trying to send an email in French, with French letters (i.e. characters) that have accents. There are 2 different French versions, one a plain text message body, the other an HTML message body. The HTML email version comes through just fine, accents and all. However, the plain text version comes through with the characters with accents entirely missing.
How do I specify encoding for the plain text body so that the characters with accents will appear correctly in the plain text email version?
