The user didn't change the wiki's language.

They just added text in Portuguese. You could revert it (either by undoing if possible, or by editing the version of the page before their edits and saving), if it's appropriate to revert. Since you're not an admin I wouldn't go to the admin-feeling length of asking the user to edit in English if they wish to edit, but this isn't an inherent part of the wiki. It's just a user making an edit.
