Indeed. To do so it would be helpful to check the output of `fc-list` (ideally with proper patterns to make the result more similar to LilyPond's output). Nathan, since you sit at the 'source' of the problem, please also send a report to the FontConfig people if your time allows it. https://gitlab.freedesktop.org/fontconfig/fontconfig/-/issues Werner
