An interesting feature has been noticed on https://aida.co.ua - the word 𝐀𝐈𝐃𝐀𝐃𝐄𝐒𝐈𝐆𝐍 in the title and description tags is embedded in an unknown font, which, however, retains its formatting, despite the fact that the style and description tags cannot be used in the title and description tags .
At the same time, this word stands out very effectively in the list of search engine sites.
How miraculously could this be achieved?
