My computer's default language is Portuguese, and I don't want to change that. But, for some usages (especially programming) it's better to have English output, for example to copy/paste an error message on a search engine.
I would like to have emacs in English only, to have for example eshell or built-in gdb output in English.
It sounds easy but I didn't find out how to do. Is there a simple way to do that?
