Abstract

   This document describes the changes between Unicode 6.3.0 and Unicode
   11.0.0 in the context of IDNA2008.  Some additions and changes have
   been made in the Unicode Standard that affect the values produced by
   the algorithm IDNA2008 specifies.  Although IDNA2008 allows adding
   exceptions to the algorithm for backward compatibility; however, this
   document does not add any such exceptions.  This document provides
   the necessary tables to IANA to make its database consisstent with
   Unicode 11.0.0.

   To improve understanding, this document describes systems that are
   being used as alternatives to those that conform to IDNA2008.

   TO BE REMOVED AT TIME OF PUBLICATION AS AN RFC:

   This document is discussed on the i18nrp@ietf.org mailing list of the
   IETF.
