Comment 13 for bug 1643210

This is an area where there is no one right answer. I have the display name as a unicode, so how do I encode it for the header. I don't think it should ever be encoded in the character set of the poster's language because this is for a message to be sent to all list members, plus there is no guarantee that the poster's display name as encoded by the sending MUA was even encoded in Mailman's charset for the poster's language if the poster is even a member, and there is no guarantee that the translation of the 'via' can even be properly encoded in the charset of the poster's language.

Further, there is no guarantee that the poster's display name can be properly encoded in the charset of the list's preferred language either.

The most reasonable encoding of unicode that guarantees no loss of information is utf-8, and any MUA that recognizes RFC 2047 encodings at all should be able to handle utf-8 encodings.

Even if there are MUA's that can properly decode RFC 2047 encodings in, e.g., iso-2022-jp but not utf-8, I think there are as many problems with trying to encode the original display name in the list's charset as there are with utf-8 encoding. I recognize that what I've done is a compromise, but I think it's as good as any.
