Lynx actually predates the GUI mainstream browsers.

I can't think of any reason why Lynx would get its hands dirty with such 
details; it is a character cell display browser.  The only thing it 
needs to know about CJK characters is that they are double width, and it 
seems to be getting that right.  (Of course I could have missed the 
bolting on of a GUI for CJK.)

I think we need details of your GUI support.

Also the title is a bit confusing.  All the characters are being 
displayed.  However, for some proportion  of both Kanji and Kana glyphs, 
only the leftmost about three quarters is actually being rendered, even 
though there is enough space for the full glyph.  Many are being 
rendered in full,and with strokes beyond the rightmost side position of 
the failed ones.  E.g. in the line starting "[4]" if you look at both 
occurrences of "移動", 動 is truncated, but 移 isn't, but both are present.

Assuming a GUI font renderer hasn't been bolted on, and Linux or 
similar, I'd suggest running lynx under script, to capture the exact 
byte sequence being sent to the terminal emulator.
