I18N-ISSUE-39: U+2028 and U+2029 in textarea and pre elements [HTML5-bidi]

http://www.w3.org/International/track/issues/39

Raised by: Richard Ishida
On product: HTML5-bidi

This is a part of the proposals made by the "Additional Requirements for Bidi in HTML" W3C First Public Working Draft. For a full description of the use cases, please see http://www.w3.org/International/docs/html-bidi-requirements/#newline-as-separator. Here is the proposal made there:

In elements where line breaks are not collapsed, e.g. <textarea> and elements with white-space:pre|pre-line|pre-wrap, the LINE SEPARATOR (U+2028) and PARAGRAPH SEPARATOR (U+2029) characters should also break lines. PARAGRAPH SEPARATOR characters in these elements should constitute UBA paragraph breaks, while LINE SEPARATOR characters should constitute UBA whitespace.

When PARAGRAPH SEPARATOR introduces a UBA paragraph break, the base direction of the new UBA paragraph will be determined by the computed direction of the nearest ancestor element whose bidi properties require its contents to be in a separate UBA paragraph (or sequence of paragraphs), e.g. a block element or an element directionally isolated by the ubi attribute (which is being proposed in a separate bug). Furthermore, for every element on the path in between that results in the creation of an embedding or override level, e.g. a <bdo> element or any element with a dir attribute or a value other than "normal" for the unicode-bidi CSS property, the correspondeng embedding or override level is re-introduced at the start of the new UBA paragraph (to be closed at the end of the element or the UBA paragraph, whichever comes first).
