Slugifying a string is a real pain in the a**  with CodeIgniter (accented characters, apostrophes ... there is always something wrong in the slug)

Why not adding the following function once and for all in url_helper.php ?

PHP Code:

// Slugify a string
function slugify($text)
{
    // Strip html tags
    $text=strip_tags($text);
    // Replace non letter or digits by -
    $text = preg_replace('~[^\pL\d]+~u', '-', $text);
    // Transliterate
    setlocale(LC_ALL, 'en_US.utf8');
    $text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);
    // Remove unwanted characters
    $text = preg_replace('~[^-\w]+~', '', $text);
    // Trim
    $text = trim($text, '-');
    // Remove duplicate -
    $text = preg_replace('~-+~', '-', $text);
    // Lowercase
    $text = strtolower($text);
    // Check if it is empty
    if (empty($text)) { return 'n-a'; }
    // Return result
    return $text;
} 


I'm convinced this will help many many many developers around the world.
