    Hi! I want to set encoding for cmd process for russian ouput. In C# the Process has StandardOutputEncoding function, in Qt such function does not exists.

    Here is the problem:

          Thanks but Base64 encoding doesn't work in my case.

              I have tried setCodec to windows-1251, utf-8, cp1251, utf-16 but the same result:

              0_1502443496513_2017-08-11_122412.png

              void Test1::getData(QByteArray data)
              {
                  QTextStream encodeStream(data);
                  encodeStream.setCodec("windows-1251");
              
                  dataTextBrowser->append(encodeStream.readAll());
                  emit dataFinished();
              }

                Here is how in C# I have done it:

                private void myCMDEncoding()
                {
                     if (CultureInfo.CurrentUICulture.Name == "en-US")
                      {
                           myCMDProcess.StartInfo.StandardOutputEncoding = Encoding.GetEncoding(437);
                      }
                
                      if (CultureInfo.CurrentCulture.Name == "ru-RU")
                      {
                            myCMDProcess.StartInfo.StandardOutputEncoding = Encoding.GetEncoding(866);
                      }
                
                      if (CultureInfo.CurrentCulture.Name == "uk-UA")
                      {
                           myCMDProcess.StartInfo.StandardOutputEncoding = Encoding.GetEncoding(866);
                      }
                }
                

                But now I need it for C++ in Qt.

                Console output:
                0_1502444338937_2017-08-11_123722.png

                  I have fixed it by setting setCodec to IBM 866 and now it's working. Also, I included the code here, so others can find the solution.

                  void Test1::getData(QByteArray data)
                  {
                      QTextStream encodeStream(data);
                      encodeStream.setCodec("IBM 866");
                      dataTextBrowser->append(encodeStream.readAll());
                      emit dataFinished();
                  }
