I try download files from my university site. All I can found it Safari -> View -> Encoding, but it doesn't affect to downloaded files. For example file with cyryllic name: "Задания для групп 80-104Б и 80 109Б на 19.05.2020.docx" is downloading like Ð¨Ð»Ñ‹ÐºÐ¾Ð²Ð° Ð›.Ð. Ð—Ð°Ð´Ð°Ð½Ð¸Ñ Ð´Ð»Ñ Ð³Ñ€ÑƒÐ¿Ð¿ 80-104Ð‘ Ð¸ 80 109Ð‘ Ð½Ð°. How can I fix it? May be it another question, but sometimes safari also can't download file with correct file name (in english), as usual for torrent files. Just cut it.
I tried use another browser as Firefox and there is good work, that's why i think it's problem only safari ill.
