PDO_sqlsrv: wrong character encoding on field identifiers

Question

Ok i inherited a pretty bad DB Situation the Views and Tables are in use and can't or can only with a lot of work be changed.

I am trying to get a Php/Html based Tool to work with the DB.

Here is my Info:

try {
    $conn = new PDO("sqlsrv:server=$serverName;Database = $database", $uid, $pwd);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $conn->setAttribute(PDO::SQLSRV_ATTR_ENCODING, PDO::SQLSRV_ENCODING_UTF8);
} catch (PDOException $e) {
    die("Error connecting to SQL Server " . $e);
}

This is my PDO connection and

select * from munition.dbo.V_Admin_Zündhütchen order by Kaliber desc

this my query.

V_Admin_Zündhütchen is a View.

When i fetch the return and dump it like this:

$row = $sql->fetch(PDO::FETCH_ASSOC)
var_dump($row);

I get this:

array (size=5)
  'ID' => string '2' (length=1)
  'Kaliber' => string '7,62 mm' (length=7)
  'Hersteller' => string 'Vihtavuori' (length=10)
  'Z�ndtyp' => string 'Boxer' (length=5)
  'Bezeichnung' => string '1511' (length=4)

the � is supposed to be a ü

The byte sequence of what is shown as Z�ndtyp is 5A FC 6E 64 74 79 70

The Data itself is fine only the Columnames are affected:

array (size=5)
  'ID' => string '24' (length=2)
  'Kaliber' => string '12/70' (length=5)
  'Hersteller' => string 'Rottweil' (length=8)
  'Z�ndtyp' => string 'Boxer' (length=5)
  'Bezeichnung' => string 'Schrotzünder' (length=13)

So why does it not resolve properly?
