When proofing letters side by side, any sequence that has entry/exit anchors get overlapped. Here H and D have an entry anchor for the Hhook/Dhook and O has an exit anchor for the Ohorn.
The add a character prefix to the anchor name. Like #entry/#exit. Then they are only used to position the components.
There’s a mekkablue script for that, mekkablue > Anchors > Prefix all entry & exit anchors…
Without the prefix, the presence of exit/entry anchors triggers the creation of the curs (Cursive Positioning) feature.
Thank you that’s a good solution!
