IDNA2008 and Unicode 11.0.0
draft-faltstrom-unicode11-07
Abstract
This document describes the changes between Unicode 6.3.0 and Unicode
11.0.0 in the context of IDNA2008. It further suggests a path
forward for the IETF to ensure IDNA2008 follows the evolution of the
Unicode Standard.
Some changes have been made in the Unicode Standard related to the
algorithm IDNA2008 specifies. IDNA2008 allows adding exceptions to
the algorithm for backward compatibility; however, this document
makes no such changes. Thus this document requests that IANA update
the tables to Unicode 11.
The document also recomments that all DNS registries continue the
practice of calculating a repertoire using conservatism and inclusion
principles.
TO BE REMOVED AT TIME OF PUBLICATION AS AN RFC:
This document is discussed on the i18nrp@ietf.org mailing list of the
IETF.

1. Introduction
The current version of Internationalized Domain Names for
Applications (IDNA) was largely completed in 2008, and is thus known
within as "IDNA2008". It is specified in a series of documents
listed in Section 3.1. The IDNA2008 standard includes an algorithm
