Unicode 7.0 Annexes Available for Early Review

As technical work gets underway to prepare the publication of Unicode 7.0 (tentatively scheduled for June, 2014), the Unicode Technical Committee has posted proposed updates for several important specifications:

PRI #260, Proposed Update UTS #10, Unicode Collation Algorithm
PRI #261, Proposed Update UAX #15, Unicode Normalization Forms
PRI #262, Proposed Update UAX #44, Unicode Character Database

In UTS #10, collation weights are discussed more generically, with fewer references to the 16-bit weights used in the DUCET. Section 6.3.2, Large Values for Secondary or Tertiary Weights was merged into Section 6.2, Large Weight Values. In UAX #44, the derivation of the Alphabetic property has been updated and the discussion of @missing in Section 4.2.10 @missing Conventions has been simplified to reflect the revised conventions in the UCD data files, which eliminated special edge cases.

Review periods for these new public review issues close January 27, 2014. For details about reviewing and commenting, please see the Public Review Issues page.
