Make QTextStream write with UTF8 enabled?

[hakermania]

This is the code:

QFile file(home16);
               if (!file.open(QIODevice::WriteOnly)) {
                   cerr << "Cannot open file" << home16 << " for writing. The reason: "
                        << qPrintable(file.errorString()) << endl;
                   cout << "Try again."; system("echo "" > /home/$USER/.config/WallpaperChanger/Checks/text_to_buton");
          }
               QTextStream out(&file);
               out << realpath;
               file.close();

QFile file(home16);
               if (!file.open(QIODevice::WriteOnly)) {
                   cerr << "Cannot open file" << home16 << " for writing. The reason: "
                        << qPrintable(file.errorString()) << endl;
                   cout << "Try again."; system("echo "" > /home/$USER/.config/WallpaperChanger/Checks/text_to_buton");
          }
               QTextStream out(&file);
               out << realpath;
               file.close();

where `home16` is a file's path and `realpath` is a char* which contains greek characters, How will i write this character to the file `home16` without the greek characters to turn to "chinese"? Thx in advance!
