utf-8 probably doesn't work for you because the Python email library
wants to base64 encode utf-8 message bodies, and the user's MUAs
aren't properly handling that.

What Mailman version?

By every character lost, do you mean replaced with a '?' or something

Did you change from the default us-ascii for English in an attempt to
solve this or for some other reason?

Is it only the affected message that's garbled in the digest? I.e.
other messages in the digest are OK? Are the headers of the affected
message garbled too?
