title: Ghostscript 9.15 - Files splitted from a large .pdf file are corrupted
body: <p>I'm using a tool that splits large .pdf files into smaller parts and it's using Ghostscript to reduce the size of the new generated files. 
  Today I ran the tool to segmentate a pdf from itext-paulo-155 and all the files seemed to have been created correctly. However when I select and copy the chars from the new and small .pdf files into a text editor, these are all corrupted like this: </p>
  
  <pre><code>ỘỔỎồỌỐỗ ờ. ỌộỏỌ
  ọχτφσ Ởωχκκω, Ọυω.  • Ọσσ Ọχητχ, ỘỔ 
  ζσιζς@βςξθν.κιβ • 
  </code></pre>
  
  <p>I updated my ghostscript version to the newest one 9.15 and it's still happening. I've set the following params in my code: </p>
  
  <p><code>gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/screen -dNOPAUSE -dBATCH  -dQUIET -sOutputFile=</code></p>
  
  <p>Apparently Ghostscript cannot support this kind of .pdf files that appear to be common ones, they're not scanned images. Do you have any idea what can cause this weird behaviour and how can I do to make ghostscript not corrupt the chars?
  Thanks for your help.</p>
