Charset Problems?
 

The IT company hosting my site did a move to a new server recently and now my forum looks kind of funny with weird symbols replacing some of the Chinese words...

This is my site -> http://www.aromaart.com.sg/forums/index.php?langid=1

Can I fix this problem by myself? Or do I have to get the IT company hosting my site to do it?

Thanks for the help. :)
