IDNA2008 and Unicode 12.0.0

Abstract

This document describes the changes between Unicode 6.0.0 and Unicode 12.0.0 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. 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 consistent with Unicode 12.0.0.

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 i18n-discuss@ietf.org mailing list of the IETF.

Table of Contents

1. Introduction

The current version of Internationalized Domain Names for Applications (IDNA) was initiated in 2008, and despite not being completed until 2010, is widely known as "IDNA2008". It is specified in the series of documents listed in Section 2.1. The IDNA2008 standard includes an algorithm by which a derived property value is calculated based on the properties defined from the Unicode Standard.

The derived property values that can be calculated are defined in RFC 5892 [RFC5892]. The summary below is a summary to make the reading of this document easier. For definition of the terms, please see RFC 5892 [RFC5892].

When the Unicode Standard is updated, new code points are assigned and already-assigned code points can have their property values changed.

There were three incompatible changes in the Unicode standard between Unicode 5.2.0 [Unicode-5.2.0] and Unicode 6.0.0 [Unicode-6.0.0]; they are described in RFC 6452 [RFC6452]. The code points U+0CF1 and U+0CF2 had a derived property value change from DISALLOWED to PVALID, and the code point U+19DA had a change in derived property value from PVALID to DISALLOWED. These changes where exampined in great detail, but the IETF concluded that these changes to the Unicode standard did not warrant an update to RFC 5892 [RFC5892].

As described in Section 3, more incompatible changes have been made to code points between Unicode 6.0.0 and Unicode 12.0.0 [Unicode-12.0.0]; however, the changes in the derived property values do not result in exceptions (as defined in section 2.6 of RFC 5892 [RFC5892]) being added to RFC 5892 [RFC5892].

Further, in 2015, the Internet Architecture Board (IAB) issued a statement [IAB2005-1] that advised the community to avoid using any of the potentially problematic code points and asked the IETF to resolve the issues related to the code point ARABIC LETTER BEH WITH HAMZA ABOVE (U+08A1) that was introduced in Unicode 7.0.0 [Unicode-7.0.0]. In February of that year, the statement was revised [IAB2005-2] to focus on the latter request. More details about the problem of code point sequences not normalizing as one might expect appear in a draft that was part of the discussion [IDNA7].

The result of the work in the IETF was that no exception was added to RFC 5892 [RFC5892]; however, it should be noted that the review of the issues around U+08A1 indicated that this code point is not an isolated case and that a number of PVALID code points of long standing may have similar issues. While the affected code points remain PVALID in this document, identification of the problem resulted in a clarification of the review process for new Unicode versions. That clarification, which reinforces the original review plan to capture issues like these, was published as RFC 8753 [RFC8753]. Any review of Unicode versions after 12.0.0 should be made according to RFC 8753 [RFC8753]; an objective of this document is to ensure that a proper review of such versions after version 12.0.0 can be made.

2. Background

2.1. IDNA2008 Documents

IDNA2008 consists of the following documents. The documents in the set have informal names.

2.2. Additional important IDNA2008-related documents

There are other documents important for the understanding and functioning of IDNA2008, for example this.

2.3. Deployment

There are many variations on the general IDNA model in use in the various parts of the community. The following lists some of the strategies that implementations that claim to be IDNA compliant are known to use, but it should be noted the list is not complete:

  • IDNA2003 as specified in RFC 3490 [RFC3490] and RFC 3491 [RFC3491]. Those specifications are dependent on case folding and NFKC normalization and on tables that specify for each code point whether it is allowed to be used or not, with a distinction made between use for "stored strings" and "query strings". The tables themselves are dependent on Unicode 3.2 [Unicode-3.2.0].
  • A number of variations on IDNA2003, sometimes presented as "updated IDNA2003" or the like, which follow the principles of IDNA2003 as understood by the implementers but that use tables that represent how the implementers believe Stringprep [RFC3454] and Nameprep [RFC3491] would have evolved had the IETF not moved in the direction of IDNA2008 instead.
  • A mix between IDNA2003 and IDNA2008 where code points assigned to Unicode after Unicode 3.2.0 [Unicode-3.2.0] have derived property value calculated according to the algorithm specified in IDNA2008.
  • A mix between IDNA2003 and IDNA2008 according to the Unicode Technical Standard #46 [UTS-46]. Because that document specifies different profiles, there are several different variations that leave users with no guarantee that two applications claiming conformance to UTS#46 will interoperate well with each other much less with conforming IDNA2008 implementations. UTS#46 is ultimately based on a normative table very much like the one used by Stringprep [RFC3454] but updated for each new version of Unicode.
  • The (normative) IDNA2008 algorithm applied to whatever version of Unicode Standard exists in the operating system and/or libraries used, independent of whatever version of tables appears in the (non-normative) IANA database.

In practice, the Unicode Consortium creates a maximum set of code points by assigning code points in the Unicode Standard. The IDNA2008 rules use the Unicode Standard to create a further subset of code points and context that are permitted in DNS labels associated with its PVALID, and CONTEXT (CONTEXTJ or CONTEXTO) derived property values. DNS registries and other organizations that deal with IDNs are supposed to create their own subsets from IDNA2008 for use by those registries and organizations.

This progressive subsetting and narrowing of the repertoire of code points that can be used in labels is an implementation of the principles of being conservative when deciding what code points to include in such a subset. SAC-084 [SAC-084] and RFC 6912 [RFC6912] recommend to DNS registries and other organizations to be conservative when creating their subsets, and to use the principle of creating subsets by inclusion.

3. Notable Changes Between Unicode 6.0.0 and 12.0.0

Among the changes between the Unicode versions, most code points that change derived property value change from UNASSIGNED to PVALID or from UNASSIGNED to DISALLOWED. The interesting changes in derived property values include other changes. All changes between the major versions of Unicode can be found in Appendix A (6.0.0-7.0.0), Appendix B (7.0.0-8.0.0), Appendix C (8.0.0-9.0.0), Appendix D (9.0.0-10.0.0), Appendix E (10.0.0-11.0.0) and Appendix F (11.0.0-12.0.0).

3.1. Changes between Unicode 6.0.0 and 7.0.0

  • Change in number of characters in each category:
  • PVALID changed from 97418 to 99867 (+2449)
  • UNASSIGNED changed from 865081 to 861509 (-3572)
  • CONTEXTJ did not change, at 2
  • CONTEXTO did not change, at 25
  • DISALLOWED changed from 151586 to 152709 (+1123)
  • TOTAL did not change, at 1114112
  • There are no changes made to Unicode between version 6.0.0 and 7.0.0 that impact IDNA2008 calculation of the derived property values.

The code points U+17B4 KHMER VOWEL INHERENT AQ and U+17B5 KHMER VOWEL INHERENT AA both changed the general category from Cf (Format) to Mn (Nonspacing_Mark), but that did not impact the calculation of the derived property value which stayed at DISALLOWED.

The character ARABIC LETTER BEH WITH HAMZA ABOVE (U+08A1) was introduced in Unicode 7.0.0. This was discussed extensively in the IETF, and by the IAB in their statement [IAB2005-1] requesting the IETF to investigate the issue. Specifically, the IAB stated:

  • On the same precautionary principle, the IAB recommends that the Internationalized Domain Names for Applications (IDNA) Parameters registry <http://www.iana.org/assignments/idna-tables/> not be updated to Unicode 7.0.0 until the IETF has consensus on a solution to this problem.

The discussion in the IETF concluded that although it is possible to create "the same" character in multiple ways, the issue with U+08A1 is not unique. The character U+08A1 (ARABIC LETTER BEH WITH HAMZA ABOVE) can be represented with the sequence ARABIC LETTER BEH (U+0628) and ARABIC HAMZA ABOVE (U+0654). This identical to LATIN SMALL LETTER O WITH STROKE (U+00F8), which can be represented with the sequence LATIN SMALL LETTER O (U+006F) followed by COMBINING SHORT SOLIDUS OVERLAY (U+0337).

Although the discussion about this specific code point resulted in acceptance of the derived property value of PVALID, the underlying problem with combining sequences is not understood fully. Therefore it cannot be claimed that this case can be extrapolated to other situations and other code points.

3.2. Changes between Unicode 7.0.0 and 10.0.0

  • Change in number of characters in each category:
  • Code points that changed derived property value: 0
  • PVALID changed from 99867 to 122411 (+22544)
  • UNASSIGNED changed from 861509 to 837775 (-23734)
  • CONTEXTJ did not change, at 2
  • CONTEXTO did not change, at 25
  • DISALLOWED changed from 152709 to 153899 (+1190)
  • TOTAL did not change, at 1114112
  • There are no changes made to Unicode between version 7.0.0 and 10.0.0 that impact IDNA2008 calculation of the derived property values.

3.3. Changes between Unicode 10.0.0 and 11.0.0

  • Change in number of characters in each category:
  • Code points that changed derived property value: 1
  • PVALID changed from 122411 to 122734 (+323)
  • UNASSIGNED changed from 837775 to 837091 (-684)
  • CONTEXTJ did not change, at 2
  • CONTEXTO did not change, at 25
  • DISALLOWED changed from 153899 to 154260 (+361)
  • TOTAL did not change, at 1114112
  • Georgian letters in the ranges U+10D0..U+10FA and U+10FD..U+10FF had their General Properties changed from Lo to Ll, to reflect their status as the lowercase of new Georgian case pairs. Case mappings were also added.
  • SHARADA SANDHI MARK (U+111C9) was changed from Po to Mn, and from bc=L to bc=NSM.
  • The properties for ZANABAZAR SQUARE VOWEL SIGN AI (U+11A07) and ZANABZAR SQUARE VOWEL SIGN AU (U+11A08) were corrected from Mc to Mn.
  • SPHERICAL ANGLE OPENING UP (U+29A1) was changed to Bidi_M=N.

These changes to the Unicode Standard have the following implications for these code points:

  • The newly assigned 684 characters are assigned a derived property value as of a result of applying the IDNA2008 algorithm.
  • The Georgian letters in the ranges U+10D0..U+10FA and U+10FD..U+10FF existed before IDNA2008 was created. Applying the IDNA2008 algorithm to the code points assigned the derived property value PVALID, and that value is unchanged even if the underlying Unicode properties have changed. The newly encoded Mtavruli letters have general category "Lu" and are therefore DISALLOWED.
  • The U+111C9 SHARADA SANDHI MARK was added to Unicode 8.0.0 [Unicode-8.0.0]. Applying the IDNA2008 algorithm to the code point assigned the derived property value DISALLOWED. The changes in the underlying properties in the Unicode Standard Version 11.0.0 [Unicode-11.0.0] caused the derived property value to change to PVALID.
  • The characters ZANABAZAR SQUARE VOWEL SIGN AI (U+11A07) and ZANABZAR SQUARE VOWEL SIGN AU (U+11A08) were added to Unicode 10.0.0 [Unicode-10.0.0]. Applying the IDNA2008 algorithm to the code points assigned the derived property value PVALID, and that value is unchanged even if the underlying Unicode properties have changed.
  • SPHERICAL ANGLE OPENING UP (U+29A1) existed before IDNA2008 was created. Applying the IDNA2008 algorithm to the code point assigned the derived property value DISALLOWED, and that value is unchanged even if the underlying Unicode properties have changed.

3.4. Changes between Unicode 11.0.0 and 12.0.0

  • Change in number of characters in each category:
  • Code points that changed derived property value: 0
  • PVALID changed from 122734 to 123006 (+272)
  • UNASSIGNED changed from 837091 to 836537 (-554)
  • CONTEXTJ did not change, at 2
  • CONTEXTO did not change, at 25
  • DISALLOWED changed from 154260 to 154542 (+282)
  • TOTAL did not change, at 1114112

4. U+111C9 SHARADA SANDHI MARK

As one can see in Section 3, an incompatible property change was made between Unicode 6.0.0 and 12.0.0, affecting the code point U+111C9. Its derived property value thus changed from DISALLOWED to PVALID. In situations like these, IDNA2008 allow for addition of rules to RFC 5892 [RFC5892] section 2.7. If the code point is accepted, it might still be rejected if validated by software based on older versions of Unicode than 11.0.0. As the character is rarely used outside of the group of Sharada specialists, and used in some records for indicating sandhi breaks, the conclusion is that it could either be added as an exception or allowed to change its property value, as the use of the code point is limited outside a special community. As including an exception would require implementation changes in deployed implementations of IDNA20008, the IETF has decided to not add a BackwardCompatible rule to IDNA2008 (i.e. Section 2.7 of RFC 5892 [RFC5892] for this code point. This also ensures all sandhi marks being treated in an equal way.

5. Conclusion

As described in Section 3 and Section 4, changes have been made to Unicode between version 6.0.0 and 12.0.0. Some changes to specific characters changed their derived property value, whereas other changes did not. Given the deployment considerations described in Section 2.3 and changes in the Unicode Standard described in Section 3 and Section 4, including implications to normalization, the conclusion is to not add any exception rules to IDNA2008.

This document addresses only changes to Unicode between version 6.0.0 and version 12.0.0. Changes in future Unicode versions might result in the conclusion that exception rules need to be added to IDNA2008 after the review process explained in RFC 8753 [RFC8753]. Separately from any changes in Unicode, the IETF might conclude that updates to RFC 5892 [RFC5892] or other IDNA2008 documents might become necessary; such updates might include changes to the algorithm specified in IDNA2008 as well as additional rules, categories, or other forms of tuning, like the clarifications in RFC 8753 [RFC8753].

6. IANA Considerations

IANA is requested to update the IDNA Parameters registry [IANA-IDNA] of derived property values, after the expert reviewer validates that the derived property values are calculated correctly.

7. Security Considerations

This document makes recommendations regarding the use of the IDNA2008 algorithm for calculation of derived property values, based on Unicode version 12.0.0. This recommendation does not say anything about what recommendations to make for future versions of the Unicode Standard.

Not following these recommendations can lead to various security issues. Specifically, allowing confusable characters may lead to various phishing attacks, as described in the Security Consideration Sections in the documents listed in Section 2.1.
