Maybe it is different (I have no idea about Japanese typesetting, I can only speak Chinese, English, and Korean). - There are no "halfwidth punctuation" in most Chinese fonts. All the glyphs in those fonts are of same width. Only a small portion of Chinese fonts (like Adobe's OpenType fonts) contain these glyphs in certain features. - halfwidth glyph+0.5em minus0.5em ( = 1em) is not right, the punctuation should be compressed. some combinations like ：" should also be compressed.
Sorry for the noise... I just want to say that Li Yanrui's example does not show excellent Chinese typesetting. Maybe there is something wrong here...
The spacing between the punctuation is wrong and the comma shouldn't be at the begin of the line. I made a short file with a few examples a while ago. Wolfgang
