How to turn the language in Gajim to English
Looks like Gajim has no option to change the GUI language, so you end up with the OS language, which is annoying sometimes.
To change the language back to the default, the easiest way is to delete the language dir of the language the OS is set to, e.g. “de” in my case. The language dirs are in
C:\Program Files\Gajim\lib\python3.14\site-packages\gajim\data\locale\???
When renaming the language dir, e.g. de to de_, the program does not find the current language setting and falls back to English, if you need another language than English, copying the dir of the other language over the current OS language dir should work.
