linux2...@plntyk.name changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |linux2...@plntyk.name --- Comment #4 from linux2...@plntyk.name --- I have observed this bug - it seems there is some issue with the definition and / or "correct" usage of language codes in environment variables. POSIX vars: for example LANG, LC_ALL with long language like de_DE.UTF-8 , de_DE however KDE / Plasma seems to use 2 letter from ISO-3166-1 : Those are added to the LANGUAGE var that the UI uses and that is configured and manipulated in the "Settings" with a fallback / plasma translations (?) list. source: https://help.ubuntu.com/community/EnvironmentVariables#The_LANGUAGE_priority_list This can be verified by executing qemu-system-x86_64 # English Menu LANGUAGE=de:en_GB qemu-system-x86_64 # English LANGUAGE=de_DE:en_GB qemu-system-x86_64 # German / Deutsch also curious: LANGUAGE=de:en_GB:en:fr:zh_CN qemu-system-x86_64 # Chinese LANGUAGE=de:en_GB:en:fr:en_US:zh_CN qemu-system-x86_64 # Chinese LANGUAGE=de:en_GB:en:fr_FR:en_US:zh_CN qemu-system-x86_64 # French env|grep LANG LANGUAGE=de:en_GB:en_US:fr LANG=de_DE.UTF-8 using plasma 5.19.5 Arch Linux here -- You are receiving this mail because: You are watching all bug changes.
