I have a friend who uses Gnome translated to Swedish, while I use the English (US) translation. Sometimes I need to guide him through application menus, and to do that easily I need to check the swedish names of menu items and labels. To do that I want to start a single application with the Swedish locale. Is that possible, and if so, how do I do that?
I have tried to start the application from the terminal with LC_ALL set. That works for example with firefox but it fails for gnome apps, like gnome-control-center:
LC_ALL=sv_SE.utf-8 firefox # Works fine, ui strings with swedish locale. LC_ALL=sv_SE.utf-8 gnome-control-center # Fails, ui string still in en_US locale.
Of course I can change settings for my entire Gnome session to Swedish and restart, but that’s a bit cumbersome when all I want is just to check the translation for this one specific application.
