Try next code:

{exp:channel:entries channel="filme" orderby="title" sort="asc" dynamic="off" limit="1000"}
<?php
mb_internal_encoding ("utf-8");
$letter = mb_strtoupper((mb_substr('{title}', 0, 1)));
if (!in_array($letter, $temp)) {
    echo "<a href='$letter'>".$letter."</a>";
    $temp[] = $letter;
}
?>

{/exp:channel:entries}
