Proposed Draft UTR #53, Unicode Arabic Mark Ordering Algorithm Now Available for Public Review

The Unicode Consortium has released Proposed Draft Unicode Technical Report #53, Unicode Arabic Mark Ordering Algorithm. This UTR describes an algorithm for determining correct rendering of Arabic combining mark sequences.

The combining classes of Arabic combining characters in Unicode are a mixture of special classes for specific marks plus two more generalized classes for all the other marks. For many years this has resulted in inconsistent rendering for sequences with multiple combining marks such as:


The algorithm described in this UTR provides a method to reorder Arabic combining marks in order to accomplish the following goals:
  • The inside-out rendering rule will display combining marks in the expected visual order.
  • Ensure identical display of canonically equivalent sequences.
  • Provide a mechanism for overriding the display order in exceptional cases.
The document is in “Proposed Draft” state, and made available for public review and comment. Information about this type of document can be found on the About Unicode Technical Reports page.

For information about how to discuss this Public Review Issue and how to supply formal feedback, please see the PRI #359 page.

Unicode CLDR 32α available for testing

cldr v31 alpha The alpha version of Unicode CLDR 32 is available for testing. The alpha period lasts until the beta release on September 27, which will include updates to the LDML spec. The final release is expected on October 19.

CLDR 32 provides an update to the key building blocks for software supporting the world's languages. This data is used by all major software systems for their software internationalization and localization, adapting software to the conventions of different languages for such common software tasks.

CLDR 32 included a Survey Tool data collection phase, with a resulting significant increase in data size, especially for emoji names/annotations and geographic subdivision names. Other enhancements include rule-based number formats for additional languages, a new “disjunctive” list style (a, b, or c), and fixes for Chinese collation and transliteration. The draft release page at http://cldr.unicode.org/index/downloads/cldr-32 lists the major features, and has pointers to the newest data and charts. It will be fleshed out over the coming weeks with more details, migration issues, known problems, and so on. Particularly useful for review are:
Please report any problems that you find using a CLDR ticket. We'd also appreciate it if programmatic users of CLDR data download the xml files and do a trial integration to see if any problems arise.

New Emoji Subcommittee Vice-Chairs

silhouette imageThe Emoji Subcommittee (ESC) is on the front lines of Unicode emoji. It is responsible for accepting requests for new emoji and emoji sequences, helping requesters to fill out missing areas in their proposals, and providing prioritized recommendations to the Unicode Technical Committee.

Peter Edberg is stepping down as the co-chair of ESC, a role he has filled since its inception. He is one of the key people involved in Unicode emoji since the very beginning, so we are very lucky that he will continue as one of the technical leaders of ESC, and remain the co-author of “Unicode Emoji” (UTS #51). To ensure the smooth operation of the ESC, we have three eminently-qualified new vice-chairs: Jeremy Burge, who has been responsible for crafting and refining proposals from the most popular requests received at Emojipedia; Jennifer 8 Lee, who has played a pivotal role in developing, inspiring, and mentoring emoji requests through Emojination; and Tayfun Karadeniz, who has researched, organized, and shepherded emoji in the very popular areas of smileys and human-form emoji. All three have already made lasting contributions to the work of the ESC, and we welcome them in their new roles.

— Mark Davis, ESC chair
