Appendix E. Common Content Encodings

In an ideal world, the only character encoding (or, loosely, "character set") that you'd ever see would be UTF-8 (utf-8), and Latin-1 (iso-8859-1) for all those legacy documents. However, the encodings mentioned below exist and can be found on the Web. They are listed below in order of their English names, with the lefthand side being the value you'd get returned from $response->content_charset. The complete list of character sets can be found at http://www.iana.org/assignments/character-sets.
