 #         Line Breaking Rules
 #         Implement default line breaking as defined by 
-#         Unicode Standard Annex #14 Revision 29 for Unicode 6.2
+#         Unicode Standard Annex #14 Revision 34 for Unicode 8.0
 #         http://www.unicode.org/reports/tr14/
+#         tailored as noted in 2nd paragraph below..
 #
 #         TODO:  Rule LB 8 remains as it was in Unicode 5.2
 #         This is only because of a limitation of ICU break engine implementation,
 #         not because the older behavior is desirable.
+#
+#         This tailors the line break behavior to correspond to CSS
+#         line-break=normal (BCP47 -u-lb-normal) as defined for languages other than 
+#         Chinese & Japanese.
+#         It sets characters of class CJ to behave like ID.
