Hi Eli,

I fixed the problems and it now works. If you apply the patch below and load kinsaku.el, open the test.txt and M-x toggle-word-wrap. You should see the text properly wrapped: wrapping between CJK characters and whitespaces but not between ASCII characters. Also according to kinsoku rules, CJK comma will not be placed at the beginning of a line; CJK “《” will not be place at the end of a line, etc.

It determines whether we can wrap before/after a character by looking at “<“, “>” and “|” categories, roughly corresponding to “don’t wrap before”, “don’t wrap after” and “wrap before and after”.
