I am using this package Github : eluquent-sluggable-persian to use arabic language for slug, they use regular expression for the package Config File, I am not that good at it , the error i have is

ErrorException in sluggable.php line 106:
preg_replace(): Compilation failed: nothing to repeat at offset 0

sluggable.php is the config file that i should replace with the original config file, I need to know how to fix that.

The Code with the error

'method' => function($string, $separator = '-')
{
    $_transliteration = array(
        '/ä|æ|ǽ/' => 'ae',

I have Fixed The Problem , Have Replace this method with another

'method' => function ($string, $separator = '-') {
    if (is_null($string)) {
        return "";
    }

    // Remove spaces from the beginning and from the end of the string
    $string = trim($string);

    // Lower case everything
    // using mb_strtolower() function is important for non-Latin UTF-8 string | more info: https://www.php.net/manual/en/function.mb-strtolower.php
    $string = mb_strtolower($string, "UTF-8");;

    // Make alphanumeric (removes all other characters)
    // this makes the string safe especially when used as a part of a URL
    // this keeps latin characters and arabic charactrs as well
    $string = preg_replace("/[^a-z0-9_s-ءاأإآؤئبتثجحخدذرزسشصضطظعغفقكلمنهويةى]#u/", "", $string);

    // Remove multiple dashes or whitespaces
    $string = preg_replace("/[s-]+/", " ", $string);

    // Convert whitespaces and underscore to the given separator
    $string = preg_replace("/[s_]/", $separator, $string);

    return $string;
},

its Working now Thanks ^^

(Edit)

if You Want url arabic like This domain.com/category/معدات-وادوات

private function my_slug($string, $separator = '-')
{
    $string = trim($string);
    $string = mb_strtolower($string, 'UTF-8');

    // Remove multiple dashes or whitespaces or underscores
    $string = preg_replace("/[s-_]+/", ' ', $string) ;
    // Convert whitespaces and underscore to the given separator
    $string = preg_replace("/[s_]/", $separator, $string);

   return rawurldecode($string);
}
