Its shaping engine has fewer bugs and is actively developed to keep it up to date with recent developments in fonts and support for complex scripts. In the future, I hope we will be able to enable advanced features like ligatures and color emoji, but this is not yet in the code base. > What can I do to test that harfbuzz is working as expected on areas > where the difference should be observable? It depends on what scripts you use routinely. If you are using Latin scripts and little else, just verifying that you see no strange display artifacts, and that HELLO displays correctly, is enough for now. TIA
