My Emacs is a mingw bulid version.
GNU Emacs 23.0.0.1 (i386-mingw-nt5.1.2600) of 2006-10-23 on THU-2B8051EF1B3

When I move cursor to the beginning of line, only half of the "作"
character is shown, like this:

half1.png
Description: PNG image

and this:

half2.png
Description: PNG image

If I put the cursor on the left side of "作", and type C-u C-x =, it gives:

--8<---------------cut here---------------start------------->8---
        character: × (215, #o327, #xd7)
preferred charset: chinese-gb2312 (GB2312 Chinese simplified: ISO-IR-58)
       code point: 0x2141
           syntax: _    which means: symbol
         category: c:Chinese h:Korean j:Japanese l:Latin
      buffer code: #xC3 #x97
        file code: #xA1 #xC1 (encoded by coding system chinese-iso-8bit-unix)
          display: by this font (glyph code)
     -outline-Courier New-normal-r-normal-normal-13-97-96-96-c-*-iso8859-1 
(#xD7)

There are text properties here:
  auto-composed        t
  fontified            t
--8<---------------cut here---------------end--------------->8---

and put the cursor on the right side of "作", and type C-u C-x =, it gives:

--8<---------------cut here---------------start------------->8---
        character: ÷ (247, #o367, #xf7)

Oh, may be that why "作" is displayed there.
