I have tried GNU Emacs 22.0.92.1 (i386-mingw-nt5.1.2600) of 2007-01-01 on 
DTOP.
There're some similar problems as well.

describe-char of that \200 (Emacs23) is:
       character: € (128, #o200, #x80)
preferred charset: iso-8859-1 (Latin-1 (ISO/IEC 8859-1))
      code point: 0x80
          syntax: w  which means: word
        category: l:Latin |:While filling, we can break a line at this 
character.
     buffer code: #xC2 #x80
       file code: not encodable by coding system chinese-gbk-unix
         display: no font available


In NTEmacs 22.0.92.1 when I press AltGr-E, it sais in minibuffer: \200 is 
undefined.

The variable w32-recognize-altgr is t. It behaves same in Emacs22.
It's interesting, M-@ does work in Emacs. That is Alt-AltGr-q, or Left Alt - 
Right Alt - q.

The keyboard is German (Germany) - German. And Windows XP SP2.

I've tested in ntemacs 22. It is a little different. If I press ü, it also 
waits in minibuffer ü- .
Then I press SPACE. It displays \221\374\240. C-u C-x = on it:

 character: ? (48672, #o137040, #xbe20)
   charset: chinese-gb2312 (GB2312 Chinese simplified: ISO-IR-58.)
code point: #x7C #x20
    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 #xFC #xA0
 file code: #xEF #xBF #xBD (encoded by coding system mule-utf-8-dos)
   display: by this font (glyph code)
    -outline-Arial Unicode 
MS-normal-r-normal-normal-13-97-96-96-p-*-gb2312*-* (#x9F31)

Please find the screenshot in the attachment.
The word is 'größer'. If the cursor is moved over the ö or ß, it can be 
displayed correctly.
Otherwise, the two letters look like a strange chinese character.
The third one is 'Mit freundlichen Grüßen', the ü and ß can't be displayed.

This is same on both ntemacs23 and ntemacs22. But it can be displayed on 
Emacs under Linux.
