Link in a letter to a Russian-language domain, how to implement it?

Question

PHP

Good evening. The task in the letter is to place a link to a Russian-language domain.
If I paste the text: <a href="http://домен.рф/активация/">Активация</a>, Gmail encodes the link with urlencode.

<a href="http://домен.рф/активация/" target="_blank" data-saferedirecturl="
https://www.google.com/url?q=http://%D0%B4%D0%BE%D0%BC%D0%B5%D0%BD.
%D1%80%D1%84%2F%D0%B0%D0%BA%D1%82%D0%B8%D0%B2%D0%B0%D1%86%D0%B8%D1%8F%2F
&amp;source=gmail">Активация</a>

If I encode the Punycode domain ( http://xn--d1acufc.xn--p1ai/), then the link is generally removed from the letter...
<a>Активация</a>
In any case, following the link from the letter is impossible... Has anyone encountered this?

<a href="http://домен.рф/активация/" target="_blank" data-saferedirecturl="
https://www.google.com/url?q=http://%D0%B4%D0%BE%D0%BC%D0%B5%D0%BD.
%D1%80%D1%84%2F%D0%B0%D0%BA%D1%82%D0%B8%D0%B2%D0%B0%D1%86%D0%B8%D1%8F%2F
&amp;source=gmail">Активация</a>

This option is normal.
In href, the link is normal, and in data-saferedirecturl, a link to www.google.com, where your domain is already passed in the parameters, and the parameters should be in urlencode.
After opening this link, Google should redirect to your link.
IMHO.
