Qt 6: Replacement for QTextCodec

Bamp

Hello,
for my application I need Quazip which need QTextCodec in several files. Currently, I use core5compat module but I want a clear Qt 6 application. Is there any replacement for QTextCodec class in Qt 6 (except core5compat)?

Thank you for your answers!

Hi, yes I had a similar issue when upgrading to Qt6, I changed to using QStringConverter
Because I sometimes I to build for Qt 5.15.2 my code looks like this example:

...
// set the text encoding for the stream
#if (QT_VERSION < QT_VERSION_CHECK(6, 0, 0))
    ts.setCodec(bUtf8 ? "UTF-8" : "ISO 8859-1");
#else
    ts.setEncoding(bUtf8 ? QStringConverter::Utf8 : QStringConverter::Latin1);
#endif
...

Could you please explain better how to use the QTextStream instead the QTextCodec?
I am also porting the QuaZip using only the Qt 6 application (without the core5compat).
Thank you for your answers!

You mean how to replace QTextCodec with QStringConverter? (QTextStream remains the same in Qt6 as in Qt5)
I've only used QStringConverter for the case shown above but there are more info for example here
