NAV Web Client: Issue when opening file from Links in Purchase Order

Hi,

Problem Statement: When I access a file name with special characters (e.g. âë) from the Links attached to a document in NAV Web Client 2015, I get an error as the file name is not encoded properly.

Scenario:
I attach the following files as Links in the Purchase Order document.

1. ae.docx
2. âë.txt

In NAV RTC, I am able to open the above files successfully from Links.

However, if I try to open the âë.txt file from NAV Web Client 2015 in Internet Explorer 11, I get the error:
Cannot find ‘file://Sharedlocation/âë.txt’. Make sure the path or Internet address is correct.

It seems that due to encoding issues, the file - âë.txt, is interpreted by the browser as âë.txt and hence, the NAV Web Client gives an error.

I tried changing the settings in IE11 - language settings, encoding to utf-8 and settings in Advanced Tab, but none seem to have worked.
Not sure if there are any encoding settings which need to be done on the IIS.

Request for inputs.

Thanks.
