There was a feedback to a paragraph in CSS3 Text, 5. Line Breaking and Word Boundaries[1] in Japan:

> In several other writing systems, (including Chinese,
> Japanese, Yi, and sometimes also Korean) a line break
> opportunities are based on *syllable* boundaries, not words.

In Chinese, Yi, and Hangul, a character represents a syllable as far as I understand, but in Japanese, Kanji characters could have more than one syllable, and also there are cases where multiple characters represent single syllable (like Kana + prolonged sound mark).

Although this part is not normative, it looks like we should replace "syllable" with "grapheme cluster".

Please let me know if this change can be incorrect to any other writing systems listed here than Japanese.
