[BIDI] ]] http://dev.w3.org/html5/webvtt/#webvtt-cue-text-rendering-rules As far as I can tell, the paragraph separators for the purpose of the referenced step P1 are class B characters only. It would be nice to call it out explicitly. TR9 talks about "appropriate Newline Function" which, per 5.8 Newline Guidelines in Unicode, is platform-dependent but the listed examples are all class B characters. TR9 also talks about "higher-level protocol paragraph determination" but WebVTT doesn't have those, I think. Hence, the paragraph separators are the class B characters. 71422 1 ian 2012-07-25 02:32:17 +0000 Certainly it can be clarified... 75087 2 contributor 2012-10-02 19:14:23 +0000 Checked in as WHATWG revision r7428.
