BTW, I hope there's a way to disable or tune this... Some CJK fonts seem
to be very small (when rendered at the same size as other characters),
and I think forcing them to be spaced with 2 * the width of the default
font would make CJK characters look weird, with tons of whitespace in
between each character....

Part of the problem, of course, is that it's somewhat difficult / clunky
for the user to customize which fonts get used for different character
sets.  There's `set-fontset-font', but I've found it to be sort of hard
to control, as there doesn't seem to be any way of controlling its
interaction with faces...

[Is there a better way?]

Thanks,
