Also, RFC822 messages tend not to be Unicode themselves, _or_ ISO8859-1. Email 
message file tend to be 7-bit ASCII, with a (small, well defined) variety of 
methods for passing other text encodings though that form.

When I read a mail message from a file I do it like this:

  msg = email.parser.Parser().parse(msgfile, headersonly=headersonly)

where `msgfile` is an open file (just "open(pathname, errors='replace')"). That 
returns a Message object.
