Cannot delete special characters with str_replace

Question

I have a very trivial problem with str_replace.

I have a line with the symbol En Dash (-) as follows:

I want to remove - the dash

Html output

I want to remove the – the dash

I want to do this:

$new_string = str_replace ('-','',$string);

I tried to parse a string with html_entity_decode in order to parse a character that needs to be removed using htmlspecialchars, but without any results.

What am I doing wrong?

-EDIT- This is the full code of my script:

$title = 'Super Mario Galaxy 2 - Debut Trailer'; // Fetched from the DB, in the DB the character is - (minus) not –

$new_title = str_replace(' - ', '', $title);
$new_title = str_replace(" - ", '', $title);
$new_title = str_replace(html_entity_decode('–'),'',$title);

No one is working. Basically the problem is that the dash is stored as a minus in the database (I entered the value using the minus key), but for some strange reason, the output is -

I work on Wordpress, and the encoding is UTF-8, the same for sorting a database.

    } else {
        $len = strlen($str);
    }
    $ret = '';
    for ($i = 0; $i < $len; $i++) {
        $ret .= dechex(ord($str[$i])).' ';
