Nginx "auth_basic" string encoding

Question

What is the right encoding/charset in nginx configuration file to display accentuated characters in HTTP authentication message ?

For example, this conf file :

server {
...
    location / {
        auth_basic           "Zone sécurisée";
        auth_basic_user_file .htpasswd;
    }
}

Is displaying in Firefox' prompt window :

"Zone sÃ©curisÃ©e"

No real solution or explanation found on the web. I tried to replace é in conf file by Ã©, by &, by &#233, by =C3=A9 or adding charset utf-8 directive or =?UTF-8? at the beginning of the string but nothing works !

Official nginx doc, talking about a "string" without more explanation about encoding of accentuated characters.

NB : I have no problem with similar .htaccess file for Apache

Did you check that your editor actually saves the files in UTF8 encoding? — Sven, Jul 10 '17 at 13:10
Yes, it saved in `UTF-8` and I tried `UTF-8 with BOM` but it worst ! — Klemart3D, Jul 10 '17 at 13:39

RFC 7617 Section 3

The 'realm' parameter carries data that can be considered textual; however, `[RFC7235] does not define a way to reliably transport non- US-ASCII characters. This is a known issue that would need to be addressed in a revision to that specification.

realm parameter is the string you put in auth_basic directive. So, can't suggest anything, but stick to ASCII.
