Chinese fonts in the PDF file

Hi all,
I am using 1.1.83.9982 and encounter a problem.
The program can not show the Chinese characters. All the stroke of the Chinese words (characters) are all broken.
Do I need to install some special fonts?

P.S. I open the same PDF by other program, say Adobe or other freeware /shareware with no problem.

Hi,

we havn´t heared of this happening before, which font(s) didn´t work?

regards,

Robin
