Description:
------------
I'm currently developing a piece of software system for a Russian client. When set names is set as utf8 in both execute and as one of the options in the PDO construct, no results are returned when a utf8 string is bound using bindValue();

Test script:
---------------
$stmt = $pdo->prepare('SELECT * FROM table WHERE column LIKE ?');
$stmt->bindValue(1,\'%привет%\');
$stmt->execute();

$result = $stmt->fetchAll(PDO::FETCH_ASSOC);

var_dump($result);

Expected result:
----------------
array(1) { "column" => "привет" }

Actual result:
--------------
array(0){}
