At the very begining, I can't paste any chinese characters from emacs
to crxvt-gb, nor can I paste from crxvt-gb to emacs (zh_CN.GBK
locale). With the patch I send, emacs can accept from crxvt-gb, but
still can't paste to it.

I don't know is if crxvt-gb accept "gb2312" and "gbk-0" mixed ctext.

It seems that crxvt-gb accept gb2312 designation sequence under
zh_CN.GB locale, and "gbk-0" under zh_CN.GBK locale, with emacs22, but
not with emacs-unicode-2.

I really don't know how to debug the "ctext-pre-write-conversion" and
"ctext-post-read-conversion" functions, edebug seems don't work for
them, so it hard for me to figure out the exact byte sequence.

The crxvt-gb that I installed comes from the "rxvt-ml" debian package.
