 # Reference Line Break rules for intltest rbbi/RBBIMonkeyTest.
 # Rules derived from Unicode Standard Annex #14 for Unicode 14.0.
 #
 # Note: Rule syntax and the monkey test itself are still a work in progress.
 #       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=loose (BCP47 -u-lb-loose) as defined for Chinese & Japanese.
 #         It sets characters of class CJ to behave like ID.
 #         In addition, it allows breaks:
 #         * between ID and hyphens 2010 & 2013 (both BA)
 #         * before 301C, 30A0 (both NS)
 #         * before iteration marks 3005, 303B, 309D, 309E, 30FD, 30FE (all NS)
 #         * between characters of LineBreak class IN such as 2026
 #         * before some centered punct 203C, 2047, 2048, 2049, 30FB, FF1A, FF1B,
 #           FF65 (all NS) and FF01, FF1F (both EX).
 #         * before suffix characters with LineBreak class PO and EastAsianWidth A,F,W;
 #           this includes: 00B0 2030 2032 2033 2035 2103 2109 FE6A FF05 FFE0
 #         * after prefix characters with LineBreak class PR and EastAsianWidth A,F,W;
 #           this includes: 00A4 00B1 20AC 2116 FE69 FF04 FFE1 FFE5 FFE6
 #         It allows breaking before 201C and after 201D, for zh_Hans, zh_Hant, and ja.
