From a UX perspective, what is the best way to indicate a user can change the language on a website? I see websites using the globe icon a lot.

But what I see more, is; websites translating "change language" into the language the website is currently in. How does this even make any sense, if your website is in German, the people who would want to change the language most likely don't speak German. So why is the "change language" link translated in German?
