Re: Korean should default to word-break: keep-all or not?

Hello.
My name is YoungBo Kim.
I agree your opinion bellow.
"Years ago I was told from my Korean colleague that Korean line breaking
rules should be the same as English and CJ rules should not apply"

Korean language - Hanguel, space is not used line breaking. Space is
inserted in order to classify the meaning of a character. It is clear that
the purpose and a function differ from space used by CJ.
It differs from using space, in order to change into Kanji.

I don't test bellow style rules.
/* Korean prefers to break only at spaces */
:root:lang(ko) {
word-break: keep-all;
}

Thanks.
