 #         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

+#         Chinese & Japanese.
+#         It sets characters of class CJ to behave like ID.
+#         In addition, it allows breaks:
+#         * before iteration marks 3005, 303B, 309D, 309E, 30FD, 30FE (all NS)
+#         * between characters of LineBreak class IN
