How does the Qt application process Chinese parameters during drag-and-drop, and qt drag-and-drop Chinese parameters?

You have developed an application using Qt. When you drag and drop a file to your exe and start your application, the main () function may receive Chinese parameters. How can this problem be solved correctly? The Code is as follows:

QTextCodec * codec = QTextCodec: codecForLocale (); QString arg = codec-> toUnicode (argv [I]);

The parameters passed to the application during drag and drop are encoded according to the local encoding format of the system. CodecForLocale () of QTextCodec will return the local codec of the system, and then the toUnicode () method can be converted to QString ......
