HowTo: Nginx Webserver Send Charset utf-8 Under Unix

I was told that to improve resource download parallelization in IE8 I need to send the character set to the HTTP Content-Type response header. How do I set charset utf-8 under nginx web server running on Unix like operating systems?

You need to use the ngx_http_charset_module. This module provides the specified charset to the "Content-Type" response header field. You can view such header using nothting but standard wget or curl command:

curl -I http://example.com


wget --server-response -O /dev/null http://example.com

How do I enable charset HTTP-header in Nginx?

Open your nginx.conf, enter:
# vi nginx.conf
Append/modify the following directive in http, server, or location:

charset UTF-8;

Save and close the file. Reload the nginx web server, enter:
# /usr/local/nginx/sbin/nginx -s reload

How do I test charset HTTP-header?

Type the following command:
$ wget --server-response -O /dev/null http://www.cyberciti.biz
$ curl -I http://www.cyberciti.biz
Sample outputs:

HTTP/1.1 200 OK
Server: nginx
Date: Mon, 05 Nov 2012 16:42:51 GMT
Content-Type: text/html; charset=UTF-8
Connection: keep-alive
