Insert Chinese from Php page yields strange characters 四分衛

Hello,

I am trying to write a small translation engine using MySQL and PHP 5.

I have a php page that allows users to insert new records into a dictionary database.

Here's what I've done:
1) The php page calls:
mysql_query("SET NAMES 'utf8'", $dblink);
mysql_query("SET CHARCTER SET utf8", $dblink);
So the connections between php and mysql should be in utf8 format.

2) I've also set the html to
<meta http-equiv="content-type" content="text-html; charset=utf-8">
So the php page should be receive utf-8, and I guess the form should also be taking in utf-8.

3) The database and its table has utf8_unicode_ci collation and utf8 charset

Now the weird part:
I've tried inserting an entry from phpMyAdmin into my database, and the record shows up just fine. So I am guessing mysql database is setup correctly.

However when I try to insert an entry from my php page using
$query = "INSERT INTO terms VALUE('$eng','$eng_alt','$chi','$chi_alt')";

Where $chi contains the chinese values ' 四分衛'. When I use phpMyAdmin to look at the new entry i just made, I see the chinese entry becomes '四分衛'.

The first character matches but the other two character doesn't. It also seems that the font is different. If I try other terms, some might not even have the first character matching.

I 've output $query onto the webpage right before I call mysql_query($query), and the output gives me the correct query. INSERT INTO terms VALUE('Quarterback','','四分衛','')

Does any one know what could be wrong? Help would be much appeciated!

I think it's related to the mysql_connection, corrupting the data somehow, but I am not sure. But here is my code:


---------------------

<?php header("Content-type: text/html; charset=utf-8");
/*

*/

$eng=$_REQUEST['eng'];
$chi=$_REQUEST['chi'];
$test=$_REQUEST['charset_check'];

?>

$cEncoding = mysql_client_encoding();

echo "CLIENT ENCODING: $cEncoding";

@mysql_select_db($database);

$chi=mysql_real_escape_string($chi);
$chi_alt=mysql_real_escape_string($chi_alt);

if (bin2hex($test) == "c3a4e284a2c2ae") { /* UTF-8 for "ä™®" */

echo $query;
# $query = "INSERT INTO test VALUES(convert('$chi' using utf8))";

mysql_query($query);

if(mysql_error()){ ?>

}
