What is the encoding in Yandex?

Question

PHP

I can not understand what kind of encoding in Yandex.

Example:

%D0%B7%D0%B0%D0%B9%D0%BC%D1%8B%20%D0%BE%D0%BD%D0%BB%D0%B0%D0%B9%D0%BD%20%D0%B1%D0%B5%D0%B7%20%D0%BE%D1%82%D0%BA%D0%B0%D0%B7%D0%B0

It's in the request url of the mobile version, how can I do that?
