  • Next message: Philippe Verdy: "RE: New Public Review Issue: Proposed Update UTS #18"

    There is a draft 3 version of the proposed update of UAX#31: Identifier
    and Pattern Syntax. In response to feedback on the use of ZWJ and ZWNJ in
    Indic, this draft removes restriction on scripts for ZWJ and ZWNJ, but
    allows further restrictions in R1a, pointing to UAX36 for security issues.
    (Note that this draft is related to public review item #96). See

    There is also a draft 2 version of the proposed update of UAX#29:Text
    Boundaries. This update addsCR, LF, Extend, and Control as needed,
    clarifies use of "Any" , updates MidLetter to include U+2018, andadds a new
    kind of grapheme cluster: extended combining character sequences. See

    Areas where the UTC would like particular feedback are highlighted as
    Notes to Reviewers. Please review and provide feedback via the online form
    at Feedback received by the next UTC
    meeting (Oct 15-17) will be reviewed at that meeting.
