      The Topic name MAY be any string which can be encoded as UTF-8 up to 65535 bytes in length.

      Snippet from Section 2.2 of v3.1 specification.
      ---------------------------------------------------------------
      The topic name is a UTF-encoded string. See the section on MQTT and UTF-8 for more information. Topic name has an upper length limit of 32,767 characters.

      Snippet in Appendix A -
      --------------------------------
      The following principles apply to the construction and content of a topic tree:
      > The length is limited to 64k but within that there are no limits to the number of
      levels in a topic tree.

      Should the topic length on PUBLISH command be restricted to 32,767 characters ?
