QWebView doesn't display correctly unicode

[binaural]

I have a compiled qt embedded 4.6.2 .for arm successfully and try to run simple browser:

int main(int argc, char *argv[])
{
        QApplication a(argc, argv);
        QWebView *view = new QWebView();
 
        view->load(QUrl("/home/index.html"));
        view->showFullScreen();
 
        return a.exec();
}

int main(int argc, char *argv[])
{
        QApplication a(argc, argv);
        QWebView *view = new QWebView();

        view->load(QUrl("/home/index.html"));
        view->showFullScreen();
        
        return a.exec();
}

To copy to clipboard, switch view to plain text mode 

I have a problem with displaying some of the unicode characters in webpages. I'm from Slovakia and we have some special characters. In my case e.g. character ľ isn't display correctly (just blank space instead). I compile qt with unicode font but it doesn't help. How can I make my web browser display correctly webpages?

Thanks,

Marek
