Why Can't insert chinese into MS-ACCESS by COM ??
----------------------------------------------------------
Example:

$conn = new COM("ADODB.Connection") or die("ADO connect failed!");

$rs = new COM("ADODB.RecordSet") or die("ADO recordset failed??");

$conn->open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=test.mdb"); 

$str="This is a bug!"

$rs = $conn->Execute("insert into [Table_A](Contents) values('".$str."');"); 
---------------------------------------------------------

When i use COM  insert the variable $str  to column [Contents] of the [Table_A].
I found it only support insert English.
When $str is a English string it success.
But when $str is a Chinese string it abnormal.
