Krakozyabry when distributing txt?

Question

Nginx

If you follow the url to txt, then in the browser it gives krakozyabry. If you save on the PC, then there is no krakozyabr.
Added to the http block
charset utf-8;
does not help.
Config, nginx and PC restarted, does not help either. How to fix?
nginx 1.21.3 (windows)

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}

        sendfile           on;
      sendfile_max_chunk 1m;
      root gdeto;
    }
  }
}

response headers:

Answer 1

content of the text in what encoding then?
the web server does not touch text files.
the browser must look at the request headers if it is a text file, and prefer the meta charset tag if it is html, but when the file is opened locally, the encoding is determined automatically by the content (statistical analysis).
There is also a moment, the browser can remember the last encoding that you chose (for the site or globally not sure here), i.e. when you chose a non-utf encoding, now he shows it to you, just select Automatic in the browser menu
