PHP-разбиение на страницы Различные символы в URL

Когда пользователь ищет A B URL показывает A+B на первой странице, но на второй странице это меняется с A%20B,
или если ищет A&B есть A%26B на первой странице, но это меняется с A&B на второй странице. Что я могу сделать, чтобы одинаковые символы оставались на каждой следующей странице?
