title: Converting correctly pdf to ps and vice-versa
body: <p>I'm using "pdftops" to convert .pdf files to .ps files and then "ps2pdf" for the reverse process (poppler-utils). The problem is that when creating the .pdf files from the .ps files, the text looks ok, but when i try to copy it, the characters are very strange (it's like they are corrupted). I used these tools on other files for a long time and it worked fine.
  I also tried "pdftohtml -xml" to create an .xml file, and the text is ok (the characters are extracted correctly). </p>
  
  <ol>
  <li>What problem could it be regarding the conversion? Maybe if I use "pdftops" and "ps2pdf" are there some options that need to be changed? </li>
  <li>If I create the .xml output, is there a way to create a .pdf file from the .xml file ?</li>
  </ol>
