I uploaded a beta that might fix it, but it needs more testing. The issue might have been introduced when support was added for more complex ligature building, compare for instance this:
Thanks Hans! Indeed, it was a fix, but there are still problems I find in further testing, see attachment for this code:
\definefont[amiri][file:UthmanTN1Ver10.ttf*arabic at 17 pt]
\define[1]\Arab{\setupalign[r2l]\amiri#1}
\starttext
\Arab{
لرَّحْمَـٰنِ
}
\stoptext
In context the two signs are set one upon the other ("sukun" and
"fatha"), see the second attachment (word) for the correct setting. But
now this has nothing todo with ligatures, deactivating them does not
help now.
