A bug when use '%' in \datedsubsection{}

For example:

`\datedsubsection{\textbf{上海交通大学Top10\%}, 上海}{2013 -- 至今}`

After you compiled it,there will be a file:` resume-zh_CN.synctex(busy)`, and when you compile it again,you will get error:
```
Runaway argument?
{上海交通大学Top10\BOOKMARK [2][-]{subsection.1.2}{西安电子\ETC.
! File ended while scanning use of \@@BOOKMARK.

\par
l.11 \begin{document}

```
And need to delete the file:` resume-zh_CN.synctex(busy)`

This bug only appears in the Chinese resume.

Reproduce the issue in the Chinese resume by compiling a \datedsubsection{} containing an escaped percent sign, then compile it again and inspect resume-zh_CN.synctex(busy) and the reported \@@BOOKMARK error. Done means the Chinese resume compiles repeatedly without requiring deletion of the generated busy file.
