Text messages do not get the content-length header as you know that a string will not contain any nulls you can assume that the terminating null is the only one you will find in a text message. The bytes message does use the content length header as the payload could contain any number of nulls. The broker and the various clients use this distinction to determine when a message is text or bytes.
