Can't type compose characters in gnome-shell (St) entries
This worked under 3.26.2, but now that I'm on 3.27.92 (both from Ubuntu packages) it's broken.
- Make sure a compose key is set in Tweaks
- Press alt-f2
- Type compose : )
If it works you should see a unicode smiley, and if it's broken you just see :).
I noticed this pretty much straight away because my passphrase has a compose character in it so I couldn't type it until I figured out that copy and paste worked...
