My website (IIS6, ASP.net, VB.net) has to send out several email messages, some in html, some in text, and the encoding of international characters works well throughout the site. However, the subject lines of emails being sent refuse to accept the encoding provided.
Example: Appétit in the source shows up properly as Appétit's in the html (even in the page title) and the body of the email, but not in the subject line of an email.
Why is that and what can I do? I have tried several globalization settings in the web.config and also looked into encoding properties of the mailmessage class - but there's only bodyEncoding, so I didn't experiment there.
