My system is set to en_US.UTF-8. However I would like to use change Region, Numbers, Time, Currency etc. to a different locale. In my case it is German. So if I search the list for Germany, it only offers me en_DE for Germany and that locale doesn't exist. If you look through the list not only the locale for German is completly bogus also for others.
Compare it using 'locale -a' on a console which gives you a list of supported locales.
Other examples: ksh_DE doesn't exist. So I don't know what this is even coming from. However if I select en_DE then LC_* is set to it and all tools run in a terminal will give you a lot of warnings that invalid locales are used.
I'm on Fedora 29, plasma is 5.14.4
It looks like that Qt uses cldr, however glibc doesn't support all locales of cldr. Also it is strange that it doesn't offer de_DE which is the only supported locale by glibc.
The issue probably is that KDE sets LANG or LC_* variables to locales which don't exist. So all terminal tools like 'ls', 'git' etc. are printing warnings that I use locales which don't exist.

Yes, de_DE is also a valid locale for CLDR/libicu. The list KDE
offers is very incomplete.

KDE/Qt5 apparently uses the locale support in libicu. The list of locales
libicu supports is different from the locales glibc supports, there is considerable overlap between the list of locales supported by libicu and glibc, but the lists are not equal.
If the user chooses a locale in KDE which does not exist in glibc, it makes not sense setting the LANG or LC_* variables to such a locale.
In combination with Bug 423995 this really becomes a showstopper, since systemwide locale settings are ignored, and the kcm settings are always faulty.
This problem is reproducible on multiple machines here and another friend of mine contacted me recently because of this localization problem. Thus, it seems to be a quite common issue.

The offers for the KCM are generated using:
>QLocale::matchingLocales(QLocale::AnyLanguage, QLocale::AnyScript, QLocale::AnyCountry);
So the installed languages aren't considered, just all possibilities are displayed.
But the title of this bug report is wrong, because there are not only invalid locales shown.
@nate Could we maybe fetch the available/installed languages by running the "locale" process (Just a thought, or is there another way to do this. The translations model uses KLocalizedString::availableDomainTranslations, but this seems like a different usecase). But then we should make it easy and intuitive for the user to install additional language packs.
Also I remember having some kind of notifications of incomplete language support when I first tried out KDE. See https://unix.stackexchange.com/questions/421066/popup-language-support-is-incomplete-what-packages-does-it-want-to-install. Maybe this idea can be of use in this case.

The problem is Qt uses icu but GNU utilities use glibc. The current behavior is correct for icu, because you don't need to "generate" any locales in icu, they just work. However with glibc locale, we need to generate them. But then again, valid icu locale may not be valid glibc locale, vice versa.
