CSS3 Textで、行末における全角空白の扱いをどうするべきか、ご意見いただけますでしょうか? 半角空白同様に、行末の全角空白は右マージンを超えて、ないものとしてレイアウトされる、で正しいと思いますが、ご意見いただけましたら幸いです。 よろしくお願いいたします。 -----Original Message----- From: fantasai [mailto:fantasai.lists@inkedblade.net] Sent: Tuesday, January 10, 2012 10:37 AM To: www-style@w3.org; 'WWW International' Subject: [css3-text] scoping line break controls, characters that disappear at the end of lines In 2008 roc outlined some principles for how line breaking controls (i.e. 'white-space', at the time) are scoped to line-breaking opportunities: In <http://lists.w3.org/Archives/Public/www-style/2008Dec/0043.html> Robert O'Callahan wrote: > > 1) Break opportunities induced by white space are entirely governed by the > value of the 'white-space' property on the enclosing element.

I'm trying to encode this into the spec. My question is, are spaces (U+0020) the only characters that fall into category #1? What about the other characters in General Category Zs? http://www.fileformat.info/info/unicode/category/Zs/list.htm In particular, U+1680 is, like U+0020, expected to disappear at the end of a line. Which brings up another issue: which characters should disappear at the end of a line? Right now we keep around all those fixed-width spaces. ~fantasai
