PRI #203 Proposed Update for UTS #10: Unicode Collation Algorithmhttp://www.unicode.org/review/pri203/
This proposed update aligns with Unicode 6.1, and includes the following changes:
A major revision to the ordering of variable characters into groups, separating punctuation and symbols. Some other characters have changed ordering as well.
A new option for sorting, IgnoreSP, that ignores (shifts) only whitespace and punctuation (and not general symbols)
Clarifications or fixes to text on soft-hyphen, contiguous weights, and collation grapheme clusters.
A new section on asymmetric search.
Review notes for new UCA verification tables, and several other areas where the text will be changed.
