the site uses SharePoint Variation. SharePoint build numbers is: 14.0.6123.5000, Arabic language pack is installed , and SP1 for Arabic language pack is installed. OS: windows server 2008 R2 Enterprise.

Answer 1

Please try after removing ar from the URL.

http://SiteName/_vti_bin/listdata.svc

http://SiteName/_vti_bin/listdata.svc/FAQs

Answer 2

The URL containing web part is correct. It works well for me on non-english webs even on variation webs. The only thing I realized is that you must use display name of the list and not his URL and moreover the name is case and accent sensitive.

Answer 3

it seems this is a Bug in the system as I have been facing this issue for over a month in Office 365 and I opened a support ticket with Microsoft and they confirmed it's a bug and they will provide a hotfix for It in Office 365. I suggest you do the same by opening a ticket as you have on-premise SharePoint.
