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.
