Features:
- multi byte compatible
- handles multiple delimiters

Params:
1. string: The string being converted
2. delimiters: a string with all wanted delimiters written one after the other e.g. "-'"
3. encoding: Is the character encoding. If it is omitted, the internal character encoding value will be used.
Example Usage:
<?php
mb_internal_encoding('UTF-8');
$string = "JEAN-PAUL d'artagnan şŠ-òÀ-éÌ hello - world";
echo ucwords_specific( mb_strtolower($string, 'UTF-8'), "-'");
?>
Output:
Jean-Paul D'Artagnan Şš-Òà-Éì Hello - World
