Encoding and decoding of application/x-www-form-urlencoded encoding

encode and decode strings into and from application/x-www-form-urlencoded

The application/x-www-form-urlencoded format encodes a ordered data sets of pairs consisting of a name and a value, with pairs separated by ampersand or semicolon and names and values separated by the equal sign. Space characters are replaced with plus sign and any characters not in the unreserved character set is encoded using the percent-encoding scheme also used for resource identifiers. A percent-encoded octet is encoded as a character triplet, consisting of the percent character “” followed by the two hexadecimal digits representing that octet’s numeric value.
