Problems with python and pyQT

[silusilusilu at gmail.com]

Hi, 
i'm new with python: so excuse me for my questions....
i have this code:

    def updateLog(self, text):
        self.ui.logTextEdit.moveCursor(QTextCursor.End)
        self.ui.logTextEdit.insertHtml("<font color=\"Black\">"+text)
        self.ui.logTextEdit.moveCursor(QTextCursor.End)

logTextEdit is a QTextEdit object.With this code,i can display only ascii characters: how can i diplay text as hex and binary values?
Thanks
