Commenting out this line: (set-frame-font ascii) makes more characters use MS Gothic. However, CJK Ideographs are still not displayed with MS Gothic, but with SimHei (I don't have that font on my system, so I used SimSun instead). But I don't see a problem here, because MS Gothic covers only a very small fraction of CJK Ideographs. So Emacs does TRT here, although I couldn't figure out why it rejects MS Gothic for these characters.
