 #         Line Breaking Rules
 #         Implement default line breaking as defined by 
 #         Unicode Standard Annex #14 Revision 29 for Unicode 6.2
 #         http://www.unicode.org/reports/tr14/
 #
 #         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.

+#         2. Adjust CL, OP, and IS to handle 'comma-variants' consistently.
+#         3. Adjust CL, QU, and OP to handle quotation marks around Chinese
+#            characters.

 #           !!lookAheadHardBreak forces the run time state machine to
 #           stop immediately when a look ahead rule ( '/' operator) matches,
 #           and set the match position to that of the look-ahead operator,
 #           no matter what other rules may be in play at the time.
