title: What is the difference between Photoshop PDF and Regular PDF for the iTextSharp?
body: <p>I am using <code>iTextSharp</code> to extract text from a PDF file using this code:</p>
  
  <pre><code>PdfReader arqPDF = new PdfReader(arqPdf);
  int qtdPgs = arqPDF.NumberOfPages;
  string textoPDF = "";
  
  for (int i = 1; i &lt;= qtdPgs; i++)
  {
      textoPDF += PdfTextExtractor.GetTextFromPage(arqPDF, i, new LocationTextExtractionStrategy());
  }
  return textoPDF;
  </code></pre>
  
  <p>and everything was just fine.</p>
  
  <p>But recently I've created a PDF using Photoshop to test things up and my output just turned into some Chinese characters:</p>
  
  <pre><code>琀 攀 砀 琀 漀 ⤀ 䄀 爀 焀 甀 椀 瘀 漀   瀀 搀 昀
  </code></pre>
  
  <p>The original text is in Portuguese.</p>
  
  <p>Thanks!</p>
