The Unicode Technical Committee has posted two new issues for public review and comment. http://www.unicode.org/review/
Review periods for the new items close on January 21, 2013.
Please see the page for links to discussion and relevant documents.
Briefly, the new issues are:
PRI #232, Proposed Update UAX #9, Unicode Bidirectional Algorithm
UAX #9 will be updated for Unicode 6.2.1. This proposed update involves a substantial extension of the Unicode Bidirectional Algorithm to allow for the implementation of isolate runs. It also introduces a new X_Bidi_Class property in support of that extension. See the modifications section of the proposed update for information on specific changes to sections in the document.http://www.unicode.org/review/pri232/
PRI #233, Proposed Update UTR #20, Unicode in XML and other Markup Languages
This Unicode Technical Report will have its references corrected and various other small editorial changes made to bring it up-to-date with Unicode 6.2.http://www.unicode.org/review/pri233/
