Hi, Miles.

I had downloaded the font and try it with such settings:

1, LANG=ja_JP.utf8
2, remove all zh/ja fonts existed on my Linux, and just let it match 
"kiloji" font.
3, set emacs font size 10 or 13.

And got the result as attachments, It is readable and just looks like 
before, but the alignment issue is fixed. (NOTE the alignment of 
VERTICAL BAR)

I think you have some misunderstanding about the fix and character width 
and font width.

1, although the "kiloji" character width looks as small as monospace 
font width, but the real pixel width of the glyph is already wide enough,
    It's the font choose to leave too much space left and right of the 
character.

2, for Monospace 10, the pixelsize is 14, then it matches a "koliji 10" 
with pixelsize 12. that's to say,
*the fix only added ONE pixel left and ONE pixel right.* Can  anybody 
feel such a little alignment change?

The patch should be good enough for you and I am sure you will never 
fell the change of the alignment after the fix.

Do not guess the result and just have a try :-D
