title: PyPDF2 - Returning only blank lines. En(de)code issue?
body: <p>Got excellent help by <a href="https://stackoverflow.com/users/1248554/brth">BrTH</a> with python PDF reading <a href="https://stackoverflow.com/questions/25089033/how-to-search-keywords-in-400-pdf-files/25101783#25101783">HERE</a></p>
  
  <p>The problem now is that I'm dealing with foregin (Brazillian Portuguese) texts.
  Got and resolved "UnicodeDecodeError" fatal error adding this to BrTH's code</p>
  
  <pre><code> import codecs
  
   #next lines are inside getPDFContent function
   content += pdf.getPage(i).extractText() + "\n"
   content = content.decode("utf-8")
  </code></pre>
  
  <p>The problem now is that "print getPDFContent(f)" only returns two blank lines from any PDF I try to use it. Obviously keyword search only returns "False". Could you please help me again?</p>
