title: Replace newlines in a Unicode string
body: <p>I am trying to replace newline characters in a unicode string and seem to be missing some magic codes.</p>
  
  <p>My particular example is that I am working on AppEngine and trying to put titles from HTML pages into a <code>db.StringProperty()</code> in my model.</p>
  
  <p>So I do something like:</p>
  
  <pre><code>link.title = unicode(page_title,"utf-8").replace('\n','').replace('\r','')
  </code></pre>
  
  <p>and I get:</p>
  
  <pre><code>Property title is not multi-line
  </code></pre>
  
  <p>Are there other codes I should be using for the replace?</p>
