accept-charset="UTF-8" problem

hi ,

I use php to develop a web admin system.
the qestion is if i want the browser to
identify Chinese words in html form, what should i do

..I have add this html form

<form action ="jj.php" accept-charset="UTF-8">

It does not work . that mean the browser can not send the correct
chinese words to the mysql server. when i retreive the data ,the
browser display the data that i dont understand.


Thanks,
Ricky
