The Unicode code points and IDNA - Unicode 6.0
draft-faltstrom-5892bis-01.txt
Abstract
This document specifies IETF consensus related to and changes made to
Unicode when version 6.0 was released on Oct 11 2011. The consensus
is that no update is needed to RFC 5892 based on the changes made in
Unicode 6.0.

Internet-Draft IDNA Codepoints December 2010
1. Introduction
RFC 5892 [RFC5892] specifies an algorithm that based on The Unicode
Standard [Unicode6] defines a derived property value. Unicode 6.0
has changed GeneralCategory to three codepoints that in turn imply
the derived property value changes when the IDNA 2008 algorithm is
applied.
1.1. U+0CF1 KANNADA SIGN JIHVAMULIYA
The GeneralCategory changes for this character from So to Lo. This
implies the derived property value will change from DISALLOWED to
PVALID.
1.2. U+0CF2 KANNADA SIGN UPADHMANIYA
The GeneralCategory changes for this character from So to Lo. This
implies the derived property value will change from DISALLOWED to
PVALID.
1.3. U+19DA NEW TAI LUE THAM DIGIT ONE
The GeneralCategory changes for this character from Nd to No. This
implies the derived property value will change from PVALID to
DISALLOWED.
2. IETF Consensus
No change to RFC 5892 is needed based on the changes made in Unicode
6.
This consensus does not imply that no changes will be made to RFC
5892 for all future updates of The Unicode Standard.
The IETF will produce a new RFC of this type for every change of The
Unicode Standard even when there are no changes being made to RFC
5892, such as is the case for this document.
3. IANA Considerations
3.1. IDNA derived property value registry
IANA is to update the derived property value registry according to
RFC 5892 and property values in The Unicode Standard.

4. Security Considerations
When the algorithm presented in RFC 5892 is applied to Unicode 6.0
the result will be different from when it is applied to Unicode 5.2
for the three codepoints discussed in this document. IETF consensus
is though that the changes are minor, and that it is important IDNA
standard is aligned with the Unicode Standard.
