Is it possible to change the “/” (slash) before the page number in the pagination link to “-” (hyphen)?
Example: “mysite.com/category-name/page/2/” to “mysite.com/category-name/page-2/”

I did the following:

$base  = str_replace( 'page/'.$big, 'page-%#%', get_pagenum_link( $big, false )  );
$pages = paginate_links(
    apply_filters( 'ru_pagination_args', array(
        'base'               => esc_url_raw($base),
        'format'             => '%#%',
        'total'              => $max,
        'current'            => $cur,
        'show_all'           => false,
        'end_size'           => 1,
        'mid_size'           => 2,
        'prev_next'          => true,
        'prev_text'          => $prev,
        'next_text'          => $next,
        'type'               => 'array',
        'add_args'           => false,
        'add_fragment'       => '',
        'before_page_number' => '',
        'after_page_number'  => '',
    ) )
);

The pagination link is as I expected, but it redirects to the 404 page.

Any help is appreciated.
