The region list in the "numeric, currency and time formats" settings module contains "Germany (nds_DE)", but not "Germany (de_DE)". As there is no specific formatting in lower-saxony (nds_DE), this is certainly a bug. This is critical, since users (as me) just selecting the one existing "Germany" setting without further looking, will have their `LANG` set to `nds_DE.UTF-8`, which may not be generated at all (as in my case). This may lead to major encoding brokenness throughout the system. Note that the "Detailed settings" do contain `de_DE` and not `nds_DE`. See also bug #357424. Reproducible: Always
I see, it's indeed the case. I'll look into it.
Just a comment: I had set at my OpenSUSE tumbleweed installation the language to `nds_DE.UTF-8` by accident. This causes libreoffice to refuse to open any documents which contains umlauts (äöüß). The error message libreoffice produces is very misleading: "... does not exist" After changing the files ~/.config/plasma-locale-settings.sh content to `export LANG=de_DE.UTF-8` libreoffice behaves normally.
This is still the case in systemsettings 5.7.1.
The region list in the "numeric, currency and time formats" settings module contains the region "Deutschland - Deutsch (de_DE)". (As well as nds_DE, ksh_DE, ...) plasma: 5.12.3
