Korean is set word by word (KLREQ): Hangul, in any language, and Han
ideographs in Korean-language text take no line breaks between
characters, so lines break at spaces. Glyphs carry their language tag
for this. A paragraph attribute, koreanCharBreaks (type.para, paragraph
styles, Paragraph Style Options > Justification), breaks between
syllables instead. It is DesignCraft-only; IDML doesn't carry it.
A paragraph's kinsoku set decides which breaks it forbids, and Korean
still breaks at spaces under one.
Kinsoku still holds, also when the single-line composer has to split a
word wider than the measure: the split moves back so no line starts
with closing punctuation.
