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

Hi. Koji.
Thanks for email.

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, so we put this. But Example 3 of UAX#14, 8.2 Examples of Customization[3] says:

Frankly I am not expert in this domain. So after got your email, I
closely looked at physical things like a Korean book, newspaper and
magazine. But all of these I checked doesn't seems to use word
separators and other explicit break opportunities.

Therefore I would like to see other opinions from experts of Korean
Interest Group.

best regards,
Wonsuk.
