Sorry, at first glance I missed the significance of that. It's true, the characters are
perfectly valid and as such ASCII characters are nothing than a subset of utf-8.
No, it would then not help to set this in your conf file. But is mutt
really capable of correcting such encoding errors of the sending side, or
would that be desirable at all?

Sorry for any confusion that that might have created.
