Yes, such links look terrible and besides, they do not fit in some blocks. The short link turns into this:

Is this idea supported by anyone else besides Ivan and I?

Hello! This is what links that have Cyrillic characters in the URL look like. For example: unacms. com/d/новое-сообщение - This link in some cases will look like this: unacms.%20com/d/%D0%BD%D0%BE%D0%B2%D0%BE%D0%B5-%D1%81%D0%BE%D0%BE %D0%B1%D1%89%D0%B5%D0%BD%D0%B8%D0%B5

To avoid this, you can add a transliteration function. Something like this:

function transliterate(url) {

  const cyrillicMap = {

   'А': 'A', 'а': 'a', 'Б': 'B', 'б': 'b', 'В': 'V', 'в': 'v', 'Г': 'G', 'г': 'g',

   'Д': 'D', 'д': 'd', 'Е': 'E', 'е': 'e', 'Ё': 'Yo', 'ё': 'yo', 'Ж': 'Zh', 'ж': 'zh',

   'З': 'Z', 'з': 'z', 'И': 'I', 'и': 'i', 'Й': 'Y', 'й': 'y', 'К': 'K', 'к': 'k',

   'Л': 'L', 'л': 'l', 'М': 'M', 'м': 'm', 'Н': 'N', 'н': 'n', 'О': 'O', 'о': 'o',

   'П': 'P', 'п': 'p', 'Р': 'R', 'р': 'r', 'С': 'S', 'с': 's', 'Т': 'T', 'т': 't',

   'У': 'U', 'у': 'u', 'Ф': 'F', 'ф': 'f', 'Х': 'Kh', 'х': 'kh', 'Ц': 'Ts', 'ц': 'ts',

   'Ч': 'Ch', 'ч': 'ch', 'Ш': 'Sh', 'ш': 'sh', 'Щ': 'Shch', 'щ': 'shch', 'Ъ': '',

   'ъ': '', 'Ы': 'Y', 'ы': 'y', 'Ь': '', 'ь': '', 'Э': 'E', 'э': 'e', 'Ю': 'Yu',

   'ю': 'yu', 'Я': 'Ya', 'я': 'ya'

  };

  let transliterated = url.split('').map(char => cyrillicMap[char] || char).join('');

  transliterated = transliterated.replace(/[^-0-9a-z]/gi, '-').toLowerCase();

  return transliterated;

}

Will this ever be realized? If yes, then I would like to know, because if you enable SEO links now, there will be problems in the future, since all Cyrillic URLs will change.
