I have a VB.NET application whichs create emails. Some of that is read on the WorldClient, from MDaemon. The problem only relies on the email subject. If I create an email from Outlook and I put French characters in the subject, when the email arrives on WorldClient, the French characters are ok. However, if I put the same text in the VFP record and send that record from the VB.NET application, WorldClient is doing a weird conversion on those characters. The subject is the same source. There is no conversion. It is a simple as:

Test à Michel éèÉé

But, if I send the same VFP record into another email which uses Outlook, I can read the subject as is. The problem only relies on WorldClient combined with an email sent from VB.NET.

What could be done differently in .NET that would cause this reaction?
