SharePoint Search encodes the URL incorrectly when there are special characters in a filename on a file share

Question

In our Sharepoint Server 2013 CA, Search Administration, Content Sources, we have configured a File Share Content Source.
Search queryes works fine and it returns relevant documents from the file share content source.
But when click on a file with a filename that contains special characters like "ÁÝÚÍÓÐ", Sharepoint encodes the link to the file incorect, and when we click on the link to the file, it throws an error on the screen saying "This
page can’t be displayed".
The following picture shows an example on how Sharepoint shows encodes the URL to a file with a special character in the filename:
As you can see, the link to the file is
\\xserver1\felagstest\Kompliserað\Ólavur.pdf, but when I hoover over the file, it translates og encodes this to
\\xserver1\Felagstest\Kompliserað\Ólavur.pdf. If I manually type the correct link in the address field in Internet Explorer then it works.
What is the problem here, and more importently what is the solution to this problem?

Answer 1

This is solved in the Hotfix KB 2899469 for SharePoint Server 2013 October 14, 2014:
http://blogs.technet.com/b/stefan_gossner/archive/2014/10/14/october-2014-cu-for-sharepoint-2013-has-been-released.aspx
I installed the http://support2.microsoft.com/kb/2899469 hotfix, and now I can search and open files on external file shares with path and filenames containing non-US-ASCII characters,
without getting "This page can’t be displayed".
Where in the description of this hotfix is written, that it solves the encoding issue?
