What I did: Pressed mod+Shift+r to restart i3.
What I saw: Logging out out and bare bones console.
What I expected instead: Restarted and pretty good looking i3.

Well, cairo tries hard to stay out of the business of turning utf8 into a list of glyphs. Pango explicitly checks for valid UTF8: https://sources.debian.org/src/pango1.0/1.40.5-1/pango/pango-layout.c/?hl=1084#L1106 Since i3 is already using Pango, it already depends on GLib and so could just use
g_utf8_validatedirectly as well. (But I guess Pango (and thus also GLib) is an optional dependency…?) Also, notice that Pango prints out a warning viag_warningif passed invalid utf8.Of course. Installing git version at the moment. Next time i get this bug i will post the log.
