UTF8 to ISO 8859... conversion

[jacek]

So how can I convert the QString 'fs' - wich is already in UTF8 - to an other QString with an other encoding? Sorry for this newbie question...

You can't. QString can be only in UTF-16. However you can use whatever encoding you like while writing it to a file/stream/QByteArray.

When you read something from a file using QTextStream, you have to tell QTextStream which codec to use (if you don't like the default one) and in return you will get QStrings in UTF-16. Then you can write them to another file using different QTextStream with a different codec.

The proper workflow in Qt is:

file -> codec -> QString -> codec -> file

not:

file -> QString -> codec -> QString -> file
