Sorry, maybe too few words. My eyes are already too old to
evaluate the subpixel rendering result is better or worse
with others. So I want to understand how you feel about the
current situation.
a) latest MingLiU shows different result, it is better than old MingLiU.
b) old & latest MingLiU show same results, both worse than other fonts.
c) something else.
