使用的指令是： pdftotext -enc UTF-8 test.pdf - 2>/dev/null
但输出为空，使用Adobe Reader打开可以正常保存为txt文件，就是使用pdftotext不行。
用windows版的pdftotext也不行。PDF的编码是Identity-H，请问有其它解决方案吗？
以下是转换失败的PDF:http://pan.baidu.com/s/1eQIFZO2

Thanks to Evian for the tip, the problem has been solved.
In fact, poppler has a bug in the PDF of Identity-H. The following is the description of the bug: https://bugs.freedesktop.org/show_bug.cgi?id=35468
The following link is the patch: http://cgit.freedesktop.org/poppler/poppler/commit/?id=018892d4ceccd5e2994cdb74cd2d401293fc929d
Apply the patch and recompile to convert Identity-H encoded PDF normally.
In addition, I used the -cfg parameter in the program, but poppler 0.25 no longer supports the -cfg parameter and needs to be removed.
PS: This problem is caused by the jifile component of joomla2.5, so the code needs to be modified to make the component work properly.
