Crazy Adobe Illustrator CS3 on my Mac when dealing with Chinese fonts and number

My first experience with Adobe Illustrator CS3 wasn't a good one. The line breaks in text area seemed ot be messed up, until I found out that I have to click the paragraph break button in the "proper way" at the tool bar.

But the I encountered I problem that I couldn't resolve. No matter what I do, all the numbers I typed turned into some crazy shit symbol. After struggling for half an hour, I finally give up. I wonder if it's a bug or something.

On the positive note, I found that my Windows Chinese font can work with Mac OSX without problem at all. Pretty darn cool.
