I compiled the cvs emacs23 today.

The screenshots look even worse than your description. Do any Chinese
characters display correctly?
Do only Chinese punctuation characters display incorrectly, or does the
incorrect display start from the first punctuation character encountered?

Can you try putting the cursor on a character that is not displaying,
and pressing C-u C-x =. Then post the contents of the *Help* buffer here.

The Chinese chars in tutorial display correctly.
But the english chars in bug report buffer display wrong.

Did you mean this ? (I copied something in the minibuffer after i had
pressed the C-u C-x =)
Quit
point=137 of 136 (EOB) column=0


And I found the exactly way to reproduce this bug:
>emacs -Q RET
Firstly Emacs display scratch correctly(english, of course). Then C-h t
RET, emacs display chinese tutorial, the chinese chars display
correctly, but punctuation not. Finally switch back to the scratch
buffer, everything goes wrong.

That is the output of C-x =. If you prefix it with C-u, you should also
get a *Help* buffer with more information, including font and codepoint
for the character.

Sorry for forgetting pressed C-u, because i can not see it in minibuffer.

Here it is, in Chinese Tutorial:

         category: a:ASCII graphic characters 32-126 (ISO646
IRV:1983[4/0]) l:Latin
      buffer code: #x20
        file code: not encodable by coding system chinese-iso-8bit-unix
          display: by this font (glyph code)
     -outline-Consolas-normal-normal-normal-mono-16-*-*-*-m-*-iso10646-1

Hi Kyle,

There have been many changes to font and display related code since you
sent this bug report. Do you still see this problem?
