Arabic numbers (characters with bidi property "an") should be left to right, just as European numbers ((characters with bidi property "en"). Currently Arabic numbers are made right to left: \setupdirections[bidi=global] \starttext 12345\par ١٢٣٤٥ \stoptext Both line should have the same digits order. I think "d == "an"" in core-spa.lua line 1075 should be moved to line 1071 (I tested it and it does fix this issue for me). -- Khaled Hosny Arabic localizer and member of Arabeyes.org team
