[Swftools-common] on convert pdf which has Chinese characters

[oyster]

I am using the python bind to convert a pdf into pictures, and the
code( which you can find at the end) is from
http://www.swftools.org/gfx_tutorial.html
for my pdf files which have Chinese characters in it, I get tons of
messy characters on the picture. and the prompt shows the following
msg
I think that is about the Chinese Font, but how can I set the correct
font in my python code? thanks in advance
