Unfortunately when I use method=two for bidi, the numbers in the main body are written from right to left. I'm starting to wonder whether it does anything nontrivial at all. \usemodule[simplefonts] \setmainfont[ALM Fixed][features=arabic,range=arabic] \setupdirections[bidi=global,method=two] \setupalign[r2l] \starttext سال ۲۰۱۶ 2016 \stoptext I'm pretty sure this used to work (for example in version 2016.01.18 22:21). A similar piece of code is working fine on the website . I'm using CONTEXT version: 2016.04.01 13:01. I also verified that it is not working in version: 2016.04.10 23:52.
