Task :
Each time we see a new project in Arabic or a major update, we face the same problem : Eastern Arabic numerals are used automaticcaly (see for example the date in the page in Arabic wikipedia https://ar.wikipedia.org/w/index.php?title=%D8%A7%D9%84%D9%85%D8%A8%D8%B9%D9%84_%28%D9%8A%D8%A7%D9%81%D8%B9%29&action=history). So we ask for a change manually. It was the case, for example, in Wikiversity (T31796) and it seems that we are facing the same problem in Wikidata (see the Arabic version of the project https://www.wikidata.org/wiki/Wikidata:%D8%A7%D9%84%D8%B5%D9%81%D8%AD%D8%A9_%D8%A7%D9%84%D8%B1%D8%A6%D9%8A%D8%B3%D9%8A%D8%A9). Please try to fix the problem from the source and for the existent and future Arabic projects by setting Western numbers by default for all Arbuc projects using Mediawiki.
Thank you.
