Hi! I saw that project, it looks great!

I think the problem here is that there are two simultaneously available text APIs in Cairo. In Luxor, fontsize and fontface are the Toy API, and settext and setfontare the so-called Pro API. They're different Cairo calls and have different behaviours with respect to accessing system fonts. If you mix them, you'll get unexpected results. (I switch between them, because sometimes the Pro API gets more symbols correct, but the Toy API accesses macOS fonts better.)

I would love to have someone provide a full API to Cairo's Pro text API, complete with Pango support, but that's too advanced for me... :)

Thanks for your fast response. Yeah setting fontface and fontsize for textextents and then setfont and settext for the text works.

Yes, textextents is the Toy API one that would be mirrored in the Pro API with lots of glyph- functions (https://www.cairographics.org/manual/cairo-text.html) , but those need adding to Cairo.jl by somebody... :)
