Email.retr extracts strange = 20 characters when the body of the email has Chinese characters in it

    self.logger.info(msg)
    popinstance=poplib.POP3(self.account[0])
    self.logger.info(popinstance.getwelcome())
    popinstance.user(self.account[1])
    popinstance.pass_(self.account[2])
    try:
        (numMsgs, totalSize)=popinstance.stat()
        self.logger.info("POP contains " + str(numMsgs) + " emails")
        for thisNum in xrange(1, numMsgs + 1):
            try:
                (server_msg, body, octets)=popinstance.retr(thisNum)
            except:
                self.logger.error("Could not download email")
                raise
            text="\n".join(body)
            mesg=StringIO.StringIO(text)
            msg=rfc822.Message(mesg)
            MessageID=email.Utils.parseaddr(msg["Message-ID"])[1]
            self.logger.info("downloading email " + MessageID)
            emailpath=os.path.join(self._emailpath + self._inboxfolder + "\\" + self._sanitize_string(MessageID  + ".eml"))
            emailpath=self._replace_whitespace(emailpath)
            try:
                self._dual_dump(text,emailpath)
            except:
                pass
            self.logger.info(popinstance.dele(thisNum))
    finally:
        self.logger.info(popinstance.quit())

      

        
        
        
      

    

(server_msg, body, octets) = popinstance.retr (thisNum) returns = 20 in the body of the email when the email contains Chinese characters.

How should I do it?
