About Chinese in mysql

I can post a new topic with chinese, and the words show on the page correctly . But they show "???" in the database.

I use UTF-8 to decode.

I dont' know why? Someone help me, please.

thanks.

but some characters still showing "?"

I've done it. Use utf-8 for all of characters encoding in web application.
