HTML works but:
1. Image reference got problem.
2. Random crash about index outbound

Or you can add one more param to let me give you what base font I installed for Chinese?
Then you can use the font I papered to create PDF.
For example:
-basefont "/usr/share/fonts/ttf/
fc-cache/msyh.ttf"

You can just create all font like:
BaseFont.createFont("/usr/share/fonts/ttf/
fc-cache/msyh.ttf", BaseFont.IDENTITY_H,BaseFont.NOT_EMBEDDED);

Thanks
