[Talk-ko] CJK fallback fonts - testing needed

[Robert Helvie]

IMO the Droid font looks better for Hangul (Korea).
It is only a slight improvement in that the text is slightly darker than
the respective text of Unifont, but it does make things easier to read. And
at the smallest size, the Hangul is definitely more readable.

Hangul is more open (empty space) than the Chinese, though so I am not sure
if that darker value will make Chinese harder to read.

Personally I think the Korean (Hangul) text is a bit small and could maybe
go up a point, but again, just my opinion.

Thanks for looking out for us folks.
