Qt Garbled Output Fix: Encoding Solutions

The issue of garbled output in Qt applications is usually caused by incorrect character encoding settings. Here are some solutions:

1. Make sure that your Qt application is using the correct character encoding. In the .pro file of the Qt application, ensure that the following line is included and set to the correct encoding:

QMAKE_CXXFLAGS += -finput-charset=UTF-8
QMAKE_CXXFLAGS += -fexec-charset=UTF-8

1. Ensure that your output window is handling character encoding correctly. In a Qt application, you can use the QTextCodec class to set and convert character encoding. You can try using the QTextCodec::codecForName() function to specify the correct encoding. For example, if your output window uses UTF-8 encoding, you can try the following code:

QTextCodec *codec = QTextCodec::codecForName("UTF-8");
QTextCodec::setCodecForLocale(codec);

1. Make sure the font of your output window supports the required character encoding. Sometimes, the problem of garbled text may be caused by the font not supporting a specific character set. You can try changing the font of the output window to one that supports the required character encoding.
2. Make sure the text input in your application uses the correct encoding to avoid garbled text in the output window. You can use the QTextCodec::codecForLocale() function to convert the encoding before processing user input.

If the above methods do not solve your problem, you can try seeking help on the official Qt forum or Qt developer community, where developers may have more experience and solutions.
