* Don't use QTextStream to read from mbox, better use QDataStream. QTextStream only
* support Unicode/Latin1/Locale. So you lost information from emails with
* charset!=Unicode/Latin1/Locale (e.g. KOI8-R) and Content-Transfer-Encoding != base64
* (e.g. 8Bit). It also not help to convert the QTextStream to Unicode. By this you
* get Unicode/UTF-email but KMail can't detect the correct charset.
