    Qt 5 supports the following encodings on Windows and Mac:

    ISO-8859-1 ,latin1 ,CP819 ,IBM819 ,iso-ir-100 ,csISOLatin1 ,ISO-8859-15 ,latin9 ,UTF-32LE ,UTF-32BE ,UTF-32 ,UTF-16LE ,UTF-16BE ,UTF-16 ,Big5-HKSCS ,Big5 ,Big5-ETen ,CP950 ,windows-949 ,CP949 ,EUC-KR ,Shift_JIS ,SJIS ,MS_Kanji ,ISO-2022-JP ,JIS7 ,EUC-JP ,GB2312 ,GBK ,CP936 ,MS936 ,windows-936 ,GB18030 ,hp-roman8 ,roman8 ,csHPRoman8 ,TIS-620 ,ISO 8859-11 ,WINSAMI2 ,WS2 ,macintosh ,Apple Roman ,MacRoman ,windows-1258 ,CP1258 ,windows-1257 ,CP1257 ,windows-1256 ,CP1256 ,windows-1255 ,CP1255 ,windows-1254 ,CP1254 ,windows-1253 ,CP1253 ,windows-1252 ,CP1252 ,windows-1251 ,CP1251 ,windows-1250 ,CP1250 ,IBM866 ,CP866 ,csIBM866 ,IBM874 ,CP874 ,IBM850 ,CP850 ,csPC850Multilingual ,ISO-8859-16 ,iso-ir-226 ,latin10 ,ISO-8859-14 ,iso-ir-199 ,latin8 ,iso-celtic ,ISO-8859-13 ,ISO-8859-10 ,iso-ir-157 ,latin6 ,ISO-8859-10:1992 ,csISOLatin6 ,ISO-8859-9 ,iso-ir-148 ,latin5 ,csISOLatin5 ,ISO-8859-8 ,ISO 8859-8-I ,iso-ir-138 ,hebrew ,csISOLatinHebrew ,ISO-8859-7 ,ECMA-118 ,greek ,iso-ir-126 ,csISOLatinGreek ,ISO-8859-6 ,ISO-8859-6-I ,ECMA-114 ,ASMO-708 ,arabic ,iso-ir-127 ,csISOLatinArabic ,ISO-8859-5 ,cyrillic ,iso-ir-144 ,csISOLatinCyrillic ,ISO-8859-4 ,latin4 ,iso-ir-110 ,csISOLatin4 ,ISO-8859-3 ,latin3 ,iso-ir-109 ,csISOLatin3 ,ISO-8859-2 ,latin2 ,iso-ir-101 ,csISOLatin2 ,KOI8-U ,KOI8-RU ,KOI8-R ,csKOI8R ,iscii-mlm ,iscii-knd ,iscii-tlg ,iscii-tml ,iscii-ori ,iscii-gjr ,iscii-pnj ,iscii-bng ,iscii-dev ,TSCII

    Qt 6 currently supports just the following encodings on Windows and Mac:

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

    I understand that from Qt 6.10 a lot more encodings are going to be supported:

    https://bugreports.qt.io/browse/QTBUG-132056

    Can anyone tell me if all the original Qt 5 encodings are going to be supported in Qt 6.10 on both Windows and Mac?

      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 ... 🤷🏻‍♂️
