***
After adding language in kcm_language it need to install `langpacks-<lang>` to complete language support, langpacks-<lang> will install needed fonts and input methods for this language (https://src.fedoraproject.org/rpms/langpacks/blob/rawhide/f/langpacks.spec), fedora with gnome doing this already https://sundeep.co.in/blog/2019/07/31/langpacks-autoinstall/

STEPS TO REPRODUCE
1. Add `japanese` language to system for example.
2. Reboot.
3. There's no `langpacks-ja` package installed.

OBSERVED RESULT
No `langpacks-<lang>` package is installed in fedora. 

EXPECTED RESULT
`langpacks-<lang>` package should be installed in fedora.

Fedora needs to come up with that code please file a bug with them.

But langpacks-lang is not about locales
Comment 6 soredake 2022-06-13 17:09:58 UTC 
I don't see what's wrong with systemsettings installing langpacks package after adding a language (leaving user with no fonts needed to display this language is not good).
Comment 7 soredake 2022-06-13 17:52:08 UTC 
dnf cannot know what languages are user enabled in kde, so auto-installing packages can be done only in systemsetting or dolphin (gnome does this in gnome software)

"Fedora needs to come up with that code"
