error on generating pdf by Latex with CJK support

Question

After adding unicode characters to \title{} micro:

\title{标题}

the following error occurs when running make all-pdf with a .tex file:

Writing index file mybook.idx

?

I have added the follow setting to the .tex file:

\hypersetup{unicode=true}
\usepackage{CJKutf8}
\AtBeginDocument{\begin{CJK}{UTF8}{gbsn}}
\AtEndDocument{\end{CJK}}

If I remove the unicode characters, and replace them with acsii characters, it works well. If anything I forgot to add to the .tex to achieve this?

the minimal .tex file to reproduce the error:

if I remove the unicode characters from \title{title 中文} into \title{title}, it works well.

Answer 1

Quick fix:

\title{title \unexpanded{中文}}

Your problem is caused by an unusual definition of \maketitle in sphinxmanual class.

In the definition of \maketitle of sphinxmanual.cls, there is

\pdfinfo{
  /Author (\@author)
  /Title (\@title)
}

It's very dangerous since CJK chracters are actually macros and should not be put into pdf streams directly. So we can use eTeX's primitive \unexpanded to prevent the problem.

For more about Chinese typesetting, see How does one type Chinese in LaTeX? XeLaTeX can also solve the problem.
