URLDecode

Synopsis

                  URLDecode(URLEncodedString [, CharacterSet])

Decodes a URL-encoded string. An optional Java character set for the encoded string may be specified. Depending on your JRE, options typically include UTF-8, UTF-16, UTF-16BE, UTF-16LE, US-ASCII, and ISO-8859-1. If no character set is specified, ColdFusion defaults to the character encoding of the URL scope. URL-encoded strings have all nonalphanumeric characters replaced with their equivalent hexadecimal escape sequences. Both %20 and the plus sign (+) are treated as spaces. Here’s an example that takes a URL-encoded string and decodes it:

<cfset MyString="Why is the sky blue?">
<cfset EncodedString=URLEncodedFormat(MyString)>
<cfset DecodedString=URLDecode(EncodedString)>
   
<cfoutput>
Original String: #MyString#<br>
URL Encoded: #EncodedString#<br>
Decoded: #DecodedString#
</cfoutput>
