                            if( isset( $_GET['n'] ) && preg_match( '/[a-zA-Z]{1}/', $_GET['n'] ) && ($_GET['n'] == chr($i)) )
                                echo '<div class="abc active'. ($i==65? ' first':'') .'"><a href="'. get_post_type_archive_link('artist') .'">'.chr($i).'</a></div>';
                            else
                                echo '<div class="abc '. ($i==65? ' first':'') .'"><a href="'. get_post_type_archive_link('artist') .'?n='.chr($i).'">'.chr($i).'</a></div>';
                        if( isset( $_GET['n'] )  && ($_GET['n'] == '0-9') )
                            echo '<div class="abc alpha active"><a href="'. get_post_type_archive_link('artist') .'">0-9</a></div>';
                        else
                            echo '<div class="abc alpha "><a href="'. get_post_type_archive_link('artist') .'?n=0-9">0-9</a></div>';
                    ?>
                </div>

and

function is_first_character_persian( $text = '' ){
    $first = mb_substr($text, 0, 1, 'utf-8');
    $persian = array('?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?','?' );
    return in_array( $first, $persian );
}
