While converting a Chinese document, I have found some unnecessary line breaks. I use the v2.42 on Windows and "smart line breaks" is unchecked for this conversion (when checked, more unnecessary line breaks appear).
Command line: -dev kp2 -fs 16.5 -col 1 -ws -0
Additional Options: -bp[-] -om 0.2 -y

1. The unnecessary line break you point out has nothing to do with the spacing between Chinese characters. It occurs because the one line, due to the punctuation mark, is not fully justified (see attachment, green circle). Because the rest of the text is fully justified, k2pdfopt thinks that line, because not fully justified, has ended a paragraph. I could consider having an adjustable threshold setting for this, but for now this determination cannot be adjusted.
2. The -ws option, as you have discovered, can be tuned to a small value to allow k2pdfopt to re-flow between the characters (really should be -ws 0, not -ws -0 -- I'll have to fix that). As you can see in the attachment, k2pdfopt is correctly separating all of the Chinese characters with this setting.
3. The additional option -bp[-] that you put doesn't do anything. The brackets are used to indicate optional suffixes, e.g. when the command-line usage says -bp[+|-|--], it means you can put one of these four options: -bp, -bp+, -bp-, or -bp--.
