Hi Behdad,
</div><div><br></div><div>Thanks for the quick response. We were also considering using emscripten, but with FreeType it looked too slow. With only HarfBuzz it might just work, though. Will look into this.</div><div><br></div><div>Having the UCDN project is really cool. When do you plan to integrate it with HarfBuzz? Is there a way I can make HarfBuzz use it already?</div><div><br></div><div>I have a few other questions about how to use HarfBuzz for our needs:</div><div><ul><li>Are there best practices to layout rich text, where fonts/colors/underlines/etc. can mix?</li><li>Is HarfBuzz capable of breaking lines at a certain width?
