 # Reference Line Break rules for intltest rbbi/RBBIMonkeyTest.
 # Rules derived from Unicode Standard Annex #14 for Unicode 14.0.

 #       They are expected to change with review and the addition of support for rule tailoring.

 #         Line Breaking Rules
 #         Implement default line breaking as defined by
 #         Unicode Standard Annex #14
 #         http://www.unicode.org/reports/tr14/, tailored as noted below.
 #
 #         This tailors the line break behavior to correspond to CSS
 #         line-break=normal (BCP47 -u-lb-normal) as defined for Chinese & Japanese.
 #         It sets characters of class CJ to behave like ID.
 #         In addition, it allows breaks:
 #         * before 301C, 30A0 (both NS)
 #         It allows breaking before 201C and after 201D, for zh_Hans, zh_Hant, and ja.
