chinese character displayed as hollow box in Emacs 22.1.90

["Zhang Wei" <id.brep@gmail.com>]

Something must be changed since the release of emacs 22.1, now Emacs
22.1.90 can't find a font to display chinese characters on windows xp,
as with the chinese character "中", C-u C-x = gives:
-----------------------------------------------------------------------
  character: 中 (43856, #o125520, #xab50, U+4E2D)
    charset: chinese-gb2312 (GB2312 Chinese simplified: ISO-IR-58.)
 code point: #x56 #x50
     syntax: w 	which means: word
   category: C:Chinese (Han) characters of 2-byte character sets c:Chinese
	     |:While filling, we can break a line at this character.
buffer code: #x91 #xD6 #xD0
  file code: #xD6 #xD0 (encoded by coding system chinese-iso-8bit)
    display: no font available
