Installing Symbola "fixed" the issue - visiting the file is now almost instantaneous. So it looks like the *actual* issue might be: visiting a file with a codepoint that doesn't match any installed fonts takes minutes? I'd love to try debugging this myself, although it'll likely take a while as I've not debugged Emacs itself before :) Will start with edbug-tracing and go from there. -- Duncan Bayne +61 420 817 082 | gemini://duncan.bayne.id.au/ I usually check my mail every 24 - 48 hours.
