title: how to add to string degree symbol
body: <p>Trying to print degree (°) symbol </p>
  
  <pre><code>t = chr(176).encode('ascii')
  qp.drawText(QtCore.QPoint(50, 45), str(self.setText))
  print t
  </code></pre>
  
  <p>but getting error </p>
  
  <pre><code>UnicodeDecodeError: 'ascii' codec can't decode byte 0xb0 in position 0: ordinal not in range(128)
  </code></pre>
  
  <p>I tried to add # -<em>- coding: utf-8 -</em>- at the top of file but no luck. 
  P.S. I tried to find out on google but not working for me.</p>
  
  <p>EDIT: 
  as @Achilles says :</p>
  
  <pre><code>t = u"\u00b0"
  qp.drawText(QtCore.QPoint(50, 45), str(self.setText)+t) 
  </code></pre>
  
  <p>Thank you</p>
