2. Converting text from Windows-1252 to UTF-8:c++ QByteArray windowsData = "Héllo world!"; QTextCodec *codec = QTextCodec::codecForName("Windows-1252"); QString utf8Data = codec->toUnicode(windowsData).toUtf8(); ``` In both examples, we first create some input data in a specific encoding (UTF-8 or Windows-1252), then get a QTextCodec object for the desired target encoding (Latin-1 or UTF-8), and finally use the codec's toUnicode() method to convert the input to a QString (which encompasses all Unicode characters). In the second example, we also convert the output QString to a QByteArray in UTF-8 encoding, which may be useful if we want to write the text to a file or send it over a network connection. QTextCodec is part of the QtCore module of the Qt library, so you would need to include the appropriate header file and link against the QtCore library in your C++ program.
