Question: how to use chinese ttf file in agar?

Dear all,

I am ready to use agar in my project,  I am in China,
and want to render Chinese using msyh.ttf (which is a
beautiful vector Chinese font file released by Microsoft).

At this moment, I am working under debian lenny linux
with UTF8 as default system environment code. here I
want to ask:

1. How to load an existing ttf file from file system in agar?
    which API?
2. Does agar support UTF8 char code? I know freetype
    support it.

emm, that's all this time. Anybody can help me?

Thank you!
