Could you try to apply the effects of https://gitlab.com/lilypond/lilypond/-/merge_requests/1758 to the two problematic instances of 'Emmentaler 11', without changing the font locations? * Install `fonttools`: ``` pip install fonttools ``` * Deassemble the fonts with ``` ttx emmentaler-11.otf ``` then open the resulting `emmentaler-11.ttx` file and change the `fontRevision` field from '2.23' to '2.2307' and '2.2310', respectively. [The exact version info can be found if you search for the string '2.23.' (note the trailing '.') in the TTX file.] * Do ``` mv emmentaler-11.otf /dir/not/scanned/by/fontconfig/ ttx emmentaler-11.ttx ``` for both fonts to assemble them again, then rerun `lilypond` with the problematic example. *Theoretically*, this fixes the issue.
