[Response to private message that may prove useful to other users.]
I have a couple of emails that were generated using MS Outlook which
contain some html entities like smart quotes and the funny "-" character
which just appear as "?" characters in the archive.
MS Outlook has a nasty habit of mislabeling the charset of its
messages with iso-8859-1 instead of MS's extension to it that contain
the characters being used.
Add the following in your resource file to see if it fixes the
problem:
<CharsetAliases>
cp1252; iso-8859-1
</CharsetAliases>
Please confirm if the above works.
