An anonymous reader writes "Facebook is testing a translation feature that could overcome the language barrier many users experience on the social network. If a comment posted on a Page is in a language that is different than the one your Facebook account is set to, a Translate button may show up just below it and beside the existing Like button. Clicking on the button will translate the comment to your account language. After translation, an Original button appears instead, and if you click that it will revert the comment to the original version (and presumably offer the Translation button again)."
