Would you please provide some example characters and such a font to help 
us make it better?
or If you had a linux environment, you can also try the fix and give 
some hints.

I am a native CJK user and know well about Chinese and a little 
Japanese/Korean, I really can not understand why shall we use such a 
small font?

As I mentioned, such a small character already unreadable, font design 
should follow some standards,
If I mean to use size 10, but the font give me a very small glyph like 
size 5, these fonts is really a big problem.

Some katakana characters  in Japanese may half width, that's OK. as I 
said, it already be filtered out.
In emacs, Ctrl-h h shows a multilingual file, the Japanese string 
"Japanese (日本語)    こんにちは / ｺﾝﾆﾁﾊ"  in katakana form is half width.

Yes, I prefer leave the font auto matching.

No such a good font, except use a real CJK monospace fonts, but its 
English glyphs look weird.
