6#         Line Breaking Rules
7#         Implement default line breaking as defined by
8#         Unicode Standard Annex #14 Revision 34 for Unicode 8.0
9#         http://www.unicode.org/reports/tr14/
10#         tailored as noted in 2nd paragraph below..
11#
12#         TODO:  Rule LB 8 remains as it was in Unicode 5.2
13#         This is only because of a limitation of ICU break engine implementation,
14#         not because the older behavior is desirable.
15#
16#         This tailors the line break behavior both for Finnish and to correpond to CSS
17#         line-break=normal (BCP47 -u-lb-normal) as defined for languages other than
18#         Chinese & Japanese.
19#         It sets characters of class CJ to behave like ID.

31#  !!lookAheadHardBreak    Described here because it is (as yet) undocumented elsewhere
32#                          and only used for the line break rules.
33#
34#           It is used in the implementation of rule LB 10
35#           which says to treat any combining mark that is not attached to a base
36#           character as if it were of class AL  (alphabetic).
37#
38#           The problem occurs in the reverse rules.
39#
40#           Consider a sequence like, with correct breaks as shown
41#               LF  ID  CM  AL  AL
42#                  ^       ^       ^
43#           Then consider the sequence without the initial ID (ideographic)
44#                 LF  CM  AL  AL
45#                    ^           ^
46#           Our CM, which in the first example was attached to the ideograph,
47#           is now unattached, becomes an alpha, and joins in with the other
48#           alphas.
49#
50#           When iterating forwards, these sequences do not present any problems
51#           When iterating backwards, we need to look ahead when encountering
52#           a CM to see whether it attaches to something further on or not.
53#           (Look-ahead in a reverse rule is looking towards the start)
54#
55#           If the CM is unattached, we need to force a break.
56#
57#           !!lookAheadHardBreak forces the run time state machine to
58#           stop immediately when a look ahead rule ( '/' operator) matches,
59#           and set the match position to that of the look-ahead operator,
60#           no matter what other rules may be in play at the time.
61#
62#           See rule LB 19 for an example.
