title: Executing "pdftk my-pdf-form.pdf dump_data_fields" shows nothing
body: <p>I am using the tool <code>pdftk</code>, I have got a editable PDF and I saw in the documentation the arguments <code>dump_data_fields</code> should show me the fields of the form.</p>
  
  <p>I use this command (windows): <code>pdftk my-pdf-form.pdf dump_data_fields</code></p>
  
  <p>I am using the <code>pdftk</code> server edition.</p>
  
  <p>Documentation: <a href="https://www.pdflabs.com/docs/pdftk-man-page/" rel="noreferrer">https://www.pdflabs.com/docs/pdftk-man-page/</a></p>
  
  <p>The point is that the PDF is editable, it has got fields to write with Adobe PDF Viewer.</p>
