Seems like the FC_FONT_FEATURES pattern attribute is not implemented. I was trying to implement a version of the collect_opentype_fonts script from this repo <https://github.com/ldo/harfpy_examples>, only using Fontconfig to find all available OpenType fonts, rather than scanning a fixed set of directories, and getting the font-feature info from Fontconfig rather than HarfBuzz. However, I keep getting back null results. I see that FC_CAPABILITY is implemented, but that gives the info in a form more designed for human readability than easy parsing. _______________________________________________ Fontconfig mailing list Fontconfig@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/fontconfig
