kdelibs4support installs a tonne of icons of flags. Flags as in the icon of different countries.
It's an easy thing to miss as our Plasma code is just loading from /usr/share/kf5/locale/countries
without any API used.
Despite the kf5 name, that's still from kdelibs4support providing them. The kf5 prefix is just for co-install-ability.
We use this from Plasma for:
- the formats KCM
- the locale KCM
- the keyboard layout indicators
Apparently a copy of these icons exists in marble.
Options are:
- Put them all in breeze (country codes are part of the default icon spec)

- Use emoji flags
- Make it a plasma problem?
