It runs over the HTML and CSS and creates an applicable subset. But the Python API supports passing just some specific text. Try using that, passing any and every flag you wish. You should be able to get a font file that contains just the country flags this way. I really need to get back to this library and add predefined subsets like, say, extended Latin, or country flags! https://github.com/vintagedave/Fontimize https://github.com/vintagedave/Fontimize
