I stuck the video on the page with the encoding 1251.
<iframe width="560" height="315" src="https://www.youtube.com/embed/Sp6b1v_twh0" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> There was a problem with the name, it turned into a gibberish.
When switching to utf-8 - everything is ok.
How to make a normal display of the name on the encoding 1251?
