How to change the default encoding to UTF-8 for Apache
ApacheCharacter EncodingApache ConfigApache Problem Overview
I am using a hosting company and it will list the files in a directory if the file index.html is not there. It uses ISO 8859-1 as the default encoding.
If the server is Apache, is there a way to set UTF-8 as the default instead?
I found out that it is actually using a DOCTYPE of HTML 3.2 and then there is not charset at all... so it is not setting any encoding. But is there a way to change it to use UTF-8?
Apache Solutions
Solution 1 - Apache
In httpd.conf add (or change if it's already there):
AddDefaultCharset utf-8
Solution 2 - Apache
Add this to your .htaccess:
IndexOptions +Charset=UTF-8
Or, if you have administrator rights, you could set it globally by editing httpd.conf and adding:
AddDefaultCharset UTF-8
(You can use AddDefaultCharset in .htaccess too, but it won’t affect Apache-generated directory listings that way.)
Solution 3 - Apache
See AddDefaultCharset Directive, AddCharset Directive, and this article.

Solution 4 - Apache
On Ubuntu 12.04, it's sufficient to uncomment the line AddDefaultCharset UTF-8 in /etc/apache2/conf.d/charset. If you're using upstream Apache, the file may be called httpd.conf, and you may have to insert the line.
Solution 5 - Apache
In file .htaccess, add this line:
AddCharset utf-8 .html .css .php .txt .js
This is for those that do not have access to their server's configuration file. It is just one more thing to try when other attempts failed.
As far as performance issues regarding the use of file .htaccess, I have not seen this. My typical page load times are 150-200 ms with or without file .htaccess.
What good is performance if your page does not render correctly? Most shared servers do not allow user access to the configuration file which is the preferred place to add a character set.

For completeness, on Apache2 on Ubuntu, you will find the default charset in charset.conf in conf-available.
Uncomment the line
AddDefaultCharset UTF-8
Solution 7 - Apache
I'm not sure whether you have access to the Apache config (httpd.conf) but you should be able to set an AddDefaultCharset Directive. See:
http://httpd.apache.org/docs/2.0/mod/core.html
Look for the mod_mime.c module and make sure the following is set:
AddDefaultCharset utf-8
or the equivalent Apache 1.x docs (http://httpd.apache.org/docs/1.3/mod/core.html#adddefaultcharset).
However, this only works when "the response content-type is text/plain or text/html".
You should also make sure that your pages have a charset set as well. See this for more info:
Solution 8 - Apache
This is untested, but it will probably work.
In your .htaccess file, add:
<Files ~ "\.html?$">
Header set Content-Type "text/html; charset=utf-8"
</Files>
However, this will require mod_headers on the server.
Solution 9 - Apache
Just a hint if you have long filenames in UTF-8 format: by default they will be shortened to 20 bytes, so it may happen that the last character might be "cut in half" and therefore unrecognized properly. Then you may want to set the following:
IndexOptions Charset=UTF-8 NameWidth=*
NameWidth setting will prevent shortening your file names, making them properly displayed and readable.
As other users already mentioned, this should be added either in httpd.conf or apache2.conf (if you do have admin rights) or in .htaccess (if you don't).
Solution 10 - Apache
Where all the HTML files are in UTF-8 and don't have meta tags for content type, I was only able to set the needed default for these files to be sent by Apache 2.4 by adding both directives:
AddLanguage ru .html
AddCharset UTF-8 .html
Solution 11 - Apache
Just leave it empty: 'default_charset' in WHM :::::: default_charset =''
P.S.: In WHM, go → Home → Service Configuration → PHP Configuration Editor → click 'Advanced Mode' → find 'default_charset' and leave it blank. Just nothing, not UTF-8 and not ISO.
Solution 12 - Apache
<meta charset='utf-8'> overrides the Apache default charset (cf /etc/apache2/conf.d/charset)
If this is not enough, then you probably created your original file with the ISO 8859-1 encoding character set. You have to convert it to the proper character set:
iconv -f ISO-8859-1 -t UTF-8 source_file.php -o new file.php
Solution 13 - Apache
In my case I added this to file .htaccess:
AddDefaultCharset off
AddDefaultCharset windows-1252
