Since we’ve converted all our source and header files to unicode, we’re facing problems

  • 0

Since we’ve converted all our source and header files to unicode, we’re facing problems with german umlauts. Everything is fine in the source but QLabels and other gui components are showing umlauts garbled.

ISO-8859-1 source works fine but causes problems when switching between OSX and Windows.

Is there anything I have to set in the project file?

Environment: Qt 4.7 with Qt Creator 2.3.0 using MinGW on Windows XP SP3

    Try to call 

    QTextCodec::setCodecForCStrings(QTextCodec::codecForName("UTF-8"));
QTextCodec::setCodecForTr(QTextCodec::codecForName("UTF-8"));

    just after creating the QApplication object. QTextCodec::setCodecForTr is only needed if your using tr().

    EDIT: This works only for Qt older than version 5. Newer Qt versions expect the source files to be converted to UTF-8.
