| # Line Breaking Rules |
| # Implement default line breaking as defined by |
| # Unicode Standard Annex #14 Revision 34 for Unicode 8.0 |
| # http://www.unicode.org/reports/tr14/ |
| # tailored as noted in 2nd paragraph below. |
| # |
| # 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 |
| # line-break=normal (BCP47 -u-lb-normal) as defined for languages other than |
| # Chinese & Japanese. |
| # It sets characters of class CJ to behave like ID. |
