Links to RF domains

I apologize if this is not news to you, but it came as a surprise to me. Today I received a response from “Plato” (Yandex technical support services) to the question why one of my site does not count external links when they exist. Answer - Yandex does not understand links of the form.

Something for a long time our number one search engine responds (this, however, is definitely not new to anyone). I am afraid that it very much hinders the transition of the Runet to the Russian domains.

UPDATE
Just received another letter from some other "Plato". I quote:
“I apologize for the incorrect answer in the previous letter. Problems with the indexing of Cyrillic links of domains in the zone. RF should not arise. We will check for what reason external links are not taken into account for your site, and we will do our best to eliminate it. ”
