MinGW doesn't use ICU like MSVC for TextEncodings

      Taken from the forum https://forum.qt.io/topic/163409/qt-6.10-and-text-encodings

      Consider this program:

      #include <QCoreApplication>
#include <QStringConverter>
#include <QtDebug>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    foreach ( const QString& s, QStringConverter::availableCodecs() )
        qDebug() << s;

    return a.exec();
}

      One would think that it would provide the same output for Qt 6.10 MSVC 2022, MinGW 13.1.0, LLVM MinGW 17.0.6. But not.

      This is due to the fact that ICU is not provisioned for MinGW.

      LLVM MinGW 17.0.6
