ADDITIONAL INFORMATION

Hi - I can't reproduce an issue with that emoji on Fedora KDE 41, Yakuake 24.12.1.

A few questions to possibly help narrow things down:

* Do other emoji characters have an issue?
* Do you see that issue in the Konsole application as well?
* Could you please attach a screenshot to help understand what the incorrect rendering looks like on your device?

Thanks!

Hi John

Thank you for your reply! I'm sorry for the delay in responding—I was traveling and couldn't respond sooner.

* Do other emoji characters have an issue?
Yes.
* Do you see that issue in the Konsole application as well?
No: I tried with many, and all of them render correctly.
* Could you please attach a screenshot to help understand what the incorrect rendering looks like on your device?
Absolutely.

Incidentally:

- I checked with a friend (ArchLinux + KDE 6.3-beta2), and he confirmed that emojis render correctly on both Konsole and Yakuake.
- I also tested the Flatpak version of Yakuake (24.12.1, the same as you're using on Fedora), but emojis remain broken on my end.
It seems likely that this is a NixOS-specific issue or something related to my personal configuration. To reduce noise, I suggest closing this ticket.

Thanks again for your time!

Fair enough! Just curious, I wonder if what's described at https://nixos.wiki/wiki/Fonts#Noto_Color_Emoji_doesn.27t_render_on_Firefox might be relevant for you?

Feel free to reply back on top of this one if it turns out to not be a Nix or local issue!
