Wrong encoding for external tools

1. Have some files with umlauts in their names.
2. Configure an external tool that will list the contents of a directory:

   Executable	cmd
   Arguments	/c dir
   Working directory	<the directory which contains the files>
   Output	Show in Pane

3. Run the external tool.
   You'll get something like this:

   Starting external tool "C:\Windows\system32\cmd.exe" /c dir
    Volume in drive D is DATAPART1
   
    Volume Serial Number is B87D-781E
   
    Directory of D:\Testprojekte\Umlauts
   
   15.04.2016  17:01    <DIR>          .
   15.04.2016  17:01    <DIR>          ..
   
   15.04.2016  16:53                 0 B„rlichingen.txt
   15.04.2016  16:53                 0 G”tz.txt
   15.04.2016  16:53                 0 v”n.txt
                  3 File(s)              0 bytes
                  2 Dir(s)  203.228.852.224 bytes free
   
   "C:\Windows\system32\cmd.exe" finished
   

   If you send the output to Creator's editor, you'll see the same.

External tools should handle umlauts correctly.
