Hi Karl,

Something that came up on this list in August 2020 is that, in recent macOS versions, the monospaced Lucida fonts are not detected as such, while those in Latin Modern and TeX Gyre are. Specifically, they aren't put in the "Fixed Width" Smart Collection in the Font Book application.

Investigations continued later on the lucida-dev list in March 2021 revealed this is caused by the isFixedPitch attribute, which isn't set for them.

FontForge seems very picky in this respect, refusing to set it manually, only adding it automatically when all the glyphs in the font have exactly the same width.

As an experiment, I used ttx from the Python FontTools to manually set isFixedPitch to 1 in the POST and CFF resources. After doing that, the fonts are indeed recognized as Fixed Width in Font Book.

More testing then seemed to indicate it was the CFF resource that mattered, not the POST resource. But I wouldn't swear by it.
