* Don't use TQTextStream to read from mbox, better use TQDataStream. TQTextStream 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 TQTextStream to Unicode. By this you

* get Unicode/UTF-email but KMail can't detect the correct charset.
