    The Qt 6.10 release candidate (MinGW_64) only seems to support these encodings in QStringConverter::availableCodecs():

    UTF-16 ,UTF-16LE ,UTF-16BE ,UTF-32 ,UTF-32LE ,UTF-32BE ,ISO-8859-1

    @AndyBrice the list doesn't seem to use ICU at all. I think these codecs are the ones that Qt 6 has.

    Please try with MSVC, since MSVC comes with ICU from the Windows SDK.

    I don't think MinGW comes with ICU bundled, and I'm not sure if Qt has packaged a version for MinGW as part of the provisioning. This is done for Linux, but for Windows I don't know.

    Please also note that there is also LLVM-MinGW, but I don't think that has ICU either.

    If MSVC works, then I suggest opening a bug report at https://bugreports.qt.io/ regarding MinGW and LLVM MinGW.

      @cristian-adam I tried the MinGW_64 version because I don't have Visual Studio 2022 installed. Has anyone got Qt 6.10 and Visual Studio 2020 installed? If so, please run this and let me know that the output is:

      #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();
}

        As suspected. MinGW is treated as a second class citizen ... 🤷🏻‍♂️

          I've updated https://wiki.qt.io/Compiling-ICU-with-MinGW - Qt6 can be compiled with icu provided by mingw.

            @cristian-adam Thansk for that.

            There is quite a big difference in the encoding supported by Qt 5 and Qt 6. As far as I can make out:

            Have some of the encodings been renamed between Qt 5 and Qt 6?

              BTW I didn't find any mention of the addition of more encodings in the Qt 6.10 release notes.

              Anyone know if they have also been added back into Mac in Qt 6.10? My dev Mac is on macOS 12 and Qt 6.10 doesn't seem to support macOS 12 (it doesn't show up in the kit list, even when downloaded by the maintenance tool).

                @cristian-adam Thansk for that.

                There is quite a big difference in the encoding supported by Qt 5 and Qt 6. As far as I can make out:

                Supported by Qt 5 and Qt 6.10:

                Have some of the encodings been renamed between Qt 5 and Qt 6?

                IIRC Qt5 has its own Codecs implementation, now Qt6 uses ICU. They are two different implementations.

                  BTW I didn't find any mention of the addition of more encodings in the Qt 6.10 release notes.

                  Anyone know if they have also been added back into Mac in Qt 6.10? My dev Mac is on macOS 12 and Qt 6.10 doesn't seem to support macOS 12 (it doesn't show up in the kit list, even when downloaded by the maintenance tool).

                    @cristian-adam Thanks for the explanation. I don't suppose anyone has written down how one maps onto the other?

                      That is less than useful when you are trying to write a Windows/Mac cross-platform application!

                      I want to move Easy Data Transform from Qt 5 to Qt 6. But currently I can't without going from supporting ~60 text encodings to 8.

                        The feature is there, it's just the official build doesn't provision ICU on all platforms.

                        If you build Qt yourself using a package manager like vcpkg or conan you can get a consistent feature set.

                          @cristian-adam I used to build Qt myself, many years ago. But it just got too difficult.

                          Is ICU going to supported in a future Mac binary release?
