Query module and UTF8

Hi,

I’m confused. I used so far in a very old template (from Expression Engine 1.7.x) the query module and it was working well with this version.

The same query in a template with EE 3.5.2 cannot handle the german umlauts. If I do instead work directly with PHP, the results are correct.

I don’t see any settings to configure the character set of the EE query.

=== the query part ===

{exp:query sql="SELECT OT FROM qa WHERE ID = '{segment_3}'"}
<h1>Details zu »{OT}«</h1>
{/exp:query}

… and the result is:

Details zu »Maigret und der hartnäckigste Gast der Welt«

=== the php part ===

<?php

if (ctype_digit({segment_3}))
{ 
 $sql_q = "SELECT OT FROM qa WHERE ID = '{segment_3}'";

 $pdo= new PDO('mysql:host=localhost;dbname=xx', $username, $db_pw);

 $sql = $pdo->prepare($sql_q);
 $sql->execute();
  
 while($ae = $sql->fetch())
  {
   echo '<h1>Details zu »' . $ae['OT'] . '«</h1>';
  }
}
?>

and the result is:

Details zu »Maigret und der hartnäckigste Gast der Welt«

What could be wrong?
