indeed. LB24 says: The default line breaking algorithm approximates this with the following (LB25) rule. Note that some cases have already been handled, such as ‘9,’, ‘[9’. For a tailoring that supports the regular expression directly, as well as a key to the notation see Section 8.2, Examples of Customization. and there is a note in LineBreakTest*.txt file: Note: The Line Break tests use tailoring of numbers described in Example 7 of Section 8.2 Examples of Customization. They also differ from the results produced by a pair table implementation in sequences like: ZW SP CL. but I have yet another question: why every test in LineBreakTest.txt assumes break opportunity at the start-of-text while LB2 says: Never break at the start of text ? if these tests are for "out of context" usage, where can i read such note?
