title: Flatten a PDF with PHP (PDFTK)
body: <p>I am using PDFTK to flatten a PDF with PHP. Problem is that all special characters (É,è,à, etc.) disappear once flattened. Tried UTF-8, unicode chars, htmlentities, etc., it's all the same as a result.</p>
  
  <p>Therefore, I would like to solve PDFTK issue OR use another script to achieve this task.</p>
