Hello! My apologies for leaving this hanging for so long. It appears I had a fontconfig configuration file left over from a long time ago that was intended to manually add the path for Guix fonts to the fontconfig paths, so that I could use Ubuntu's fontconfig rather than use fontconfig from Guix. I had forgotten it was even there. Getting rid of it and re-caching the fonts like you said has fixed the issue. Not sure why I thought that was a good idea... Thank you for your help! -- Evan
