charset

The character encoding in which the string is encoded. Optional.

The following list includes commonly used values:

  • utf-8
  • iso-8859-1
  • windows-1252
  • us-ascii
  • shift_jis
  • iso-2022-jp
  • euc-jp
  • euc-kr
  • big5

  • utf-16

For more information on character encoding, see:
www.w3.org/International/O-charset.html.

Default: the character encoding of the response. See cfcontent.

URL encoding formats some characters with a percent sign and the two-character hexadecimal representation of the character. For example, a character whose code is 129 is encoded as %81. A space is encoded with a plus sign.

Query strings in HTTP are always URL-encoded.
