Followup-For: Bug #860360

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
	- create a folder in Dolphin that contains accents (e.g. from czech alphabet), place a pdf inside and open the file, Okular opens complaining that the file cannot be found, the reference to the file has wrongly encoded characters with accents. When you go to File->Open in Okular straight away, you can see the PDF file in the folder and the path to the folder has wrongly encoded accent characters.
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
	- PDF files that are in a path that contains accents cannot be opened directly by clicking on them in Dolphin
   * What was the outcome of this action?
	- The file did not open/
   * What outcome did you expect instead?
	- the file was supposed to be opened.
