[typography] Korean justification information required

r12a has just created a new issue for 
https://github.com/w3c/typography:

== Korean justification information required ==
Should the hanja be stretched with inter-character spacing at the same
 time as the Korean inter-word spaces are stretched? What if only a 
single word fits on a line, should it be stretched using 
inter-character spacing? Are there more sophisticated rules involving 
choices of justification location, as there are in Japanese where you 
adjust punctuation first and do inter-character spacing later? What if
 the whole text is hanja, such as for an ancient document?
