Text rendering letter-spacing error

    Description

      Simple text "base" renders incorrect using label:

      #include <QApplication>
      #include <QLabel>
      
      int main(int argc, char *argv[]) {
          QApplication a(argc, argv);
          QLabel label("base");
          label.show();
          return a.exec();
      }
      

       result is:

      Letter space between "ba" is too small, letter space between "as" is too large.

      Tested on Windows 10, both MinGW and MSVC. I checked default UI font using 

      QApplication::font().family()
      

      And result is "Microsoft YaHei UI".

      All UI text on QWidget have that problem, QtCreator also has the same problem. But QPlainTextEdit renders without problem.
