title: Rendering OSM XML file with Mapnik and street names
body: <p>I am rendering OSM XML tiles using <a href="http://mapnik.org/" rel="nofollow noreferrer">Mapnik</a>, but when I increase my font size for road names, some roads appear to show text twice in a row.</p>
  
  <p>Here is an image of what I mean:</p>
  
  <p><a href="https://i.stack.imgur.com/ixYCR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ixYCR.png" alt="street names"></a></p>
  
  <p>Note the unwanted repetition of:</p>
  
  <ul>
  <li>Stirling Street</li>
  <li>Atkins Street (on the right)</li>
  </ul>
  
  <p>Does anyone know how I can fix this?</p>
