[Haskell-cafe] How to specify multiple fonts for xmobar?

[Magicloud]

Hi,
    I am using xmonad + xmobar. And I am using sgi screen font.
    But sometimes I need to display CJK characters, which need another font.
    In gtk2 software, this is OK. I just specify the screen font for 
ascii. It can auto-choose a CJK font. Everything looks fine, maybe not 
pretty.
    While, xmobar does not auto-choose a CJK font, if I just specify 
screen font for ascii, it displays CJK characters in blank.
    How to fix this?
