Checking with JuliaMono author, this does not seem to be a font issue: https://github.com/cormullion/juliamono/issues/87 This has been confirmed by a harfbuzz maintainer, where you can see detailed discussion. It was suggested there to report this as an Emacs bug, which I am now doing. https://github.com/harfbuzz/harfbuzz/discussions/2790 Thanks, Stephen
