If the rule is "break on ascii whitespace",

Is there a way to achieve this: break english by word, and break
chinese by utf-8 character

You could extend your current regex so that it matches whole utf-8 
codepoints which is what git does for the builtin userdiff regexes. I've 
not tested it but I think

git config --global diff.wordregex "[[:alnum:]_]+|[^[:space:]]|$(printf 
'[\xc0-\xff][\x80-\xbf]+')"

should work. The downside is that you end up with a .gitconfig that is 
not valid utf-8. Perhaps someone else has a clever idea to get around that.
