Try this might help you
<?php
header('Content-Type: text/html; charset=utf-8');
?>
and then in the connection
<?php
$dbLink = mysql_connect($argHost, $argUsername, $argPassword);
mysql_query("SET character_set_results=utf8", $dbLink);
mb_language('uni');
mb_internal_encoding('UTF-8');
mysql_select_db($argDB, $dbLink);
mysql_query("set names 'utf8'",$dbLink);
?>

///
$SERVER = "http://localhost:8084";
$db = mysql_connect('localhost','root') or die("Not Connected");
$sldb = mysql_select_db('vifarbydata',$db);
mysql_query("set names utf8");
$sql = "SELECT * FROM `region` ";
$res = mysql_query($sql);
while($h=(mysql_fetch_array($res)))
{
$row[] = $h;
}
mysql_close($db);
/// set another character set
$SERVER = "http://localhost:8084";
$db = mysql_connect('localhost','root') or die("Not Connected");
$sldb = mysql_select_db('vifarbydata',$db);
foreach ($row as $item)
{
echo $sql = "insert into `region2` (id,name,myId) values (".$item['id'].",'".$item['name']."','".$item['myId']."') ";
mysql_query($sql);
}

#afsane, using mysqldump, you can dump the data from old_table and then import it into the new_table which has the new character encoding.
mysqldump -u user -p --no-create-info schema old_table > old_table.dump
mysql -u user -p schema new_table < old_table.dump
This will be much faster than doing a conversion via PHP.
