[Xmonad] Non-English letters in XPrompt?

Hi list, I couldn't make the XPrompt work with Chinese characters. I used the same font that works with dzen. But when I want it to auto-complete paths with Chinese characters, it completes correctly, yet incorrectly showing the characters. I simply used

shellPrompt defaultXPConfig { font = "font works fine with dzen" }

What else should I do to make the font showing the correct characters? - Xiao-Yong -- c/* __o/* <\ * (__ */\ <
