As I wrote when TUS 3.0 came out, I cannot help wondering where the idea that leads to the following in the TR on line breaking (and what's written about it in Chap 5o of TUS 3.0) came from.

Western (spaces and hyphens are used to determine breaks) UTR14> 2. East Asian (lines can break anywhere, unless prohibited) Let me make it clear that virtually NO books published in Korean uses space-based (style 1) line breaking rule. Style 2 line breaking rule is *exclusively* used for modern Korean text no matter what some broken word processors for Korean offer as an alternative to style 2 and what some web browsers (e.g. Netscape 4.x. Mozilla fixed this problem) do. I'm very alarmed to find this 'misinformation' crept into the UTS and UTR14 (now UAX #14). It would be nice if somebody in charge could get this straightened.
