Side-remark: this works via "isabelle build_fonts -d dejavu-fonts-ttf-2.37/ttf" The Isabelle/Scala sources of this tool should be obvious, see http://isabelle.in.tum.de/repos/isabelle/file/395c4fb15ea2/src/Pure/Admin/build_fonts.scala In the past, people have occasionally pointed out that the standard Isabelle font is a bit boring. If there are other high-quality fonts to be considered for the Isabelle font portfolio, I am interested to hear about them. Of course, it is also possible to use private Isabelle-derivatives of existing fonts, such as some Apple fonts that are provided with macOS. (These are usually non-free and we cannot ship them by default.) It is generally better to have all special glyphs in a single font where all sizes are carefully fit together, instead of implicit or explicit multi-font assembly in GUI frameworks.
