Why I can't type in any Chinese punctuation characters in Emacs?

For Emacs 23.2(9.开发者_开发百科0) on Mac OS X.

In the start-up screen, it has the following text

GNU Emacs 23.2.1 (x86_64-apple-darwin, NS apple-appkit-1038.29) of 2010-05-08 on black.local

I found i can't type in Chinese punctuation characters. For example, I can type in , but not ，, and " but not “ or ”, etc. Typing in the former will result in the later.

How to fix this?

Try setting the input method to `chinese-punct':

C-1 C-\chinese-punct

Afterwards, striking any punctuation key should produce in the minibuffer a list of related Chinese punctuation symbols, of which one may be selected using its corresponding number.
