Why doesn't nginx return files with Russian letters?

Question

Nginx

Good afternoon! After migrating the site to Nginx, I noticed such a problem that my site does not give files with Russian letters. Do not tell me how to deal with this?
config snippet:

# set expiration of assets to MAX for caching
    location ~* \.(ico|css|js|gif|jpe?g|png)(\?[0-9]+)?$ {
         expires max;
         log_not_found off;
         #add_header Cache-Control public;
         #add_header Access-Control-Allow-Origin *;
    }

When accessing a file with Russian letters, it gives 404, and these are the headers:

Request URL: http://stat.site.ru/gallery/%D0%A1%D0%BF%D0%B0%D1%81%D1%81%D0%BA%D0%B0%D1%8F_%D0%B1%D0%B0%D1%88%D0%BD%D1%8F_21.jpg

Other files give normally.

Answer 1

For starters, I recommend getting rid of the Cyrillic alphabet and bringing all file names back to normal, without Russian code pages. You can try to get around the problem by setting the system code page to UTF-8, renaming the files to UTF-8, giving the page explicitly indicating that you have UTF-8. Thus, you minimize the number of errors. For a complete solution, I repeat, get rid of Russian file names.
