The bug

Clockinfos that display '-' don't have the dash appear

reported at: https://github.com/orgs/espruino/discussions/7855#discussioncomment-14429124

I'm pretty sure it's because the font doesn't include a dash character, but I can't remember where I got the font from!

Installed apps

No response

Ok, it probably came from https://github.com/espruino/EspruinoDocs/blob/master/modules/sevenseg_font_tools.js

(but in that case there is a dash)
