[Mailman-Users] Uncaught runner exception: 'ascii' codec can't encode character u'\u201c'

[Sahil Tandon]

I am seeing this error with all mail sent to just one (of several)
mailman mailing lists that are operating without problems.  I found some
related discussions in the archives, but nothing that (as far as I could
tell) corresponds to what I am seeing.

Sorry for my MUA's line wrapping:

If I understand the exception correctly, 'position 0' is the first
character in the shunted pickle file?  But in the beginning of the file
I see:

 [----- start pickle file -----]
 <----- start object 1 ----->

 ...

I do not see the U+201C and am stuck trying to figure out why all mail
(regardless of content) to this - and only this list - is shunted.

Thanks for any pointers.
