1, If you use Sans font as default font, the patch will just ignore it 
and never adjust the width padding , since it is wrong setting.

2, For Sans font, it's variable pitch, every glyph in the font is 
different width.

The C-u C-x = report a font spec string.
Looks like: 
xft:-unknown-Monaco-normal-normal-normal-*-17-*-*-*-m-0-iso10646-1 (#x4B)

Note the "17" here is FONT_PIXEL_SIZE from FcPattern of fontconfig, not 
Font Size in common sense, It should be same for CJK font and English font.

So Im wondering how you get the pixelsize of fonts?
