Unicode Text Segmentation Proposed Update for 8.0

UAX #29, Unicode Text Segmentation, will be updated for Unicode 8.0. The proposed update is now available for general public review and comment.

There are several minor modifications to the Grapheme_Cluster_Break property which affect the determination of grapheme cluster boundaries for some Southeast Asian scripts.

To supply feedback on this UAX, please see http://www.unicode.org/review/pri290/ and the information page about Public Review Issues.
