Thanks, that's a useful test case. And actually it motivated me to dig a little deeper.

It turns out it's not konsole's fault after all (at least not konsole 22.08.3 on my system): I run most terminal applications in `screen`, and when I tested with your file outside of screen everything was fine (even using color emojis, btw.), but inside it wasn't (see screenshot: https://patrick-nagel.net/temp/unicode_konsole.png ).

That confused me, because I had seen Unicode working perfectly fine in screen before. Turns out the problem is how I start this particular screen session: It's a script in /etc/local.d that then uses sudo to run screen as my user (instead of root). That way, and since I didn't pass the environment from root either, screen didn't get any LANG and LC_ALL environment variables that specify a <...>.UTF-8 locale. It was an easy fix, once I knew where to look :)
