SUMMARY KDE Regional Settings Language selection - insufficient language selection blocks off access to message catalogues for non-KDE applications. STEPS TO REPRODUCE 1. Try to select Swampy Cree as primary KDE language. 2. Try to select Esperanto as primary KDE language. 3. OBSERVED RESULT At least one of those will not be possible. EXPECTED RESULT Arbitrary language selection should be possible, at least from the set of languages supported on the host system, and possibly extending to nonexistent languages, or inconsequentially translated or untranslated languages. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Debian testing (bullseye/sid) KDE Plasma Version: 5.19 KDE Frameworks Version: 5.74 Qt Version: 5.15 ADDITIONAL INFORMATION The list of languages offered by KDE plasma translations control panel seems arbitrary. * It doesn't correspond to the set of locales that have been generated by locale-gen * It doesn't correspond to the set of languages in /usr/[local/]share/i18n/SUPPORTED * It doesn't correspond to the set of languages listed in /usr/share/locale/kf5_all_languages * It doesn't correspond to any i18n or l10n packages that are installed on my system. * It doesn't (under Debian) correspond to the list of task-<language>-kde-desktop packages that are installed. * My system default language is not shown on the list of available languages. This is quite a problem, because KDE uses this language list to set the LANGUAGE environment variable for everything else. This cuts off access to the message catalogues in many languages that originate outside KDE. I ought to be able to select any arbitrary language, not just ones that KDE provides. For example, my system default is Esperanto, and a lot of applications are at least partially translated into Esperanto. The lack of selection in the KDE control module means that I need to take extra measures to see my language in non-KDE applications.
It is also noteworthy that I cannot empty the language selection list, and thereby prevent KDE from setting the LANGUAGE environment variable at all. I should be able to select an empty list in order to simply accept the host system's default settings for LANGUAGE and LC_*.
There is a workaround for this bug: The file ~/.config/plasma-localerc can be directly edited to select arbitrary languages to be used on next login. In my case, this allowed inserting "eo" into the LANGUAGE= path so that I could see more Esperanto on my desktop. Also, it allows directly setting "LANG=...", which solved some other problems having to do with language encoding. It seems that KDE likes to encode LANG=xx without explicitly specifying the encoding (LANG=xx_XX.UTF-8). This behaviour should be changed, since KDE, Qt, X11, and Linux each make their own assumptions about encodings and sometimes they seem to disagree with each other.
