title: PDF text extraction via iText returns strange characters
body: <p>I am using itext 5.3.4 to extract text from a PDF file. The code I am using to do this is below:</p>
  
  <pre><code>    PdfReaderContentParser parser = new PdfReaderContentParser(pdfReader);
      TextExtractionStrategy strategy;
      StringBuffer sb = new StringBuffer();
  
      for (int i = 1; i &lt;= pdfReader.getNumberOfPages(); i++)
      {
          strategy = parser.processContent(i, new SimpleTextExtractionStrategy());
          sb.append(strategy.getResultantText());
      }
      String text = sb.toString();
  </code></pre>
  
  <p>For a particular PDF however, an ë is returned as °. Any idea why this might happen and what can be done about it ? Is it a bug in the itext library or has there been an error in the construction of the PDF ?</p>
  
  <p>Thanks for the assistance.</p>
