In the attached font, the lam_alef-ar and lam_alef-ar.fina has top_1 etc. anchors, but the other lam-alef ligatures that use them as components don’t get the mark components automatically aligned. AmiriII.glyphs (205.5 KB)
Where was this screenshot taken from? If InDesign, which version?
I downloaded your file and the /hamzabelow-ar seems to position below the /lam_alef-ar after exporting the file and using it in Indesign CC2019 (version 14.0.2).
Also, is the ‘Adobe World Ready paragraph Composer’ enabled in InDesign
The screenshot is taken from Glyphs. The exported font has the same issue, the components are misplaced. I’m certain something weird is happening here as I checked other files I have and they don’t have this issue.
For those marks at ligatures, you need to pick the anchor you like to attached too. Select the mark and in the info box, you find an anchor symbol. Click it and pick the anchor you like.
Interesting, didn’t know about this. Works fine, thanks.
Would have been better if it worked by default, but I can imagine that in general case it is not possible to tell what part the mark belongs to (may be, as a new feature, for known ligatures the data would store also the part number of the mark).
