PHP slugifying HTML entity code backwards R

Question

I'm trying to create some clean URLs for artist names. I'm using the following to parse Pearl Jam to pearl-jam. All is fine until it tries to process KoЯn. Instead of returning korn, it is returning koand1071n. In my database, KoЯn is actually stored as

KoЯn

I'm using this code below. What can I do to handle the backwards R?

$delimiter = "-";
$clean = iconv('UTF-8', 'ASCII//TRANSLIT', $str);
$clean = str_replace("\$", "s", $clean); 
$clean = preg_replace( '/&/', 'and', $clean );
$clean = preg_replace("/[^a-zA-Z0-9\/_|+ -]/", '', $clean);
$clean = strtolower(trim($clean, '-'));
$clean = preg_replace("/[\/_|+ -]+/", $delimiter, $clean);
$clean = strtolower(trim($clean, '-'));

Answer 1

Just replace Я with a r with str_replace like you do for $

$clean = str_replace("Я", "r", $clean); 

or

$clean = str_replace("Я", "r", $clean);
