Missing character encoding definition

Problem:

The character encoding of the web page could be determined automatically, but it is not defined.

Whenever we find no character encoding specification, we try to determine it automatically by analyzing the combination of character codes we find on the page. This is not always possible, and may not be 100% reliable.

We look for character encoding specifications at these locations

  • HTTP Content-Type header
    Example:
    Content-Type: text/html; charset=utf-8
    
  • XML header
    Example:
    <?xml version="1.0" encoding="ISO-8859-1"?>
  • HTML Content-Type meta tag
    Example:
    <meta http-equiv="Content-Type" content="text/html; charset=GB2312">

Impact:

Browsers may have difficulties showing the text of the page correctly.

Although most modern browsers would also try to automatically detect the correct encoding, they may not always succeed. Also, one should keep in mind that the web is more and more surfed using devises such as mobile phones, game consoles or TV sets, which may have less capable and error tolerant browsers.

Additionally, search engines may not recognize the text of your pages correctly, so that people interested in your site's topics may not find it.

Recommendation:

Always specify the character encoding.
