Actual results: The encoding was not detected correctly and now charset was added to the content-type MIME attachment header. Expected results: The encoding should be detected properly. Not only for text/plain file as per https://bugzilla.mozilla.org/show_bug.cgi?id=636112 but for all text subtypes.
