Custom Font for GW?

Anyone knows how to make the default font look like the picture above?

Korean.

yeah but how does he make it english in korean font?

Korean client prolly uses a different font, which has bit different roman alphabet and korean letters in the same font pack.

I use Japanese font [MS UI Gothic] on windows, and the normal letters get bit like that, and kanji and kanas show as they should.

That user is probably on Korean Windows.
