Converts escaped string to an original format.
- Parameters
-
dest | Destination string. |
src | Source string. |
This function converts encoded string to the original format. The '+' symbol is replaced by the space symbol, and the % symbol followed by two hexadecimal digits is replaced by proper ASCII value (for example the exclamation mark encoded as %21).
This function should be used by CGI functions to eliminate escape symbols from a query string.
INFO:
RFC1945:The Request-URI is transmitted as an encoded string, where some characters may be escaped using the "% HEX HEX" encoding defined by RFC 1738. The origin server must decode the Request-URI in order to properly interpret the request.
