Description
It is used to decode the Escaped-encoding URL.
Escaped-encoding, or sometimes referred to as percent-encoding, is the standard of representing characters within a URI that may need special syntax handling to be correctly interpreted. It uses a sequence of three characters to encode the character to be interpreted. This triplet sequence consists of the percentage character % followed by the two hexadecimal digits representing the octet code of the original character. For example, the US-ASCII character set represents a space with octet code 32, or hexadecimal 20. Thus its URL-encoded representation is %20.
Applications may automatically escape reserved and unreserved characters, or automatically un-escape an escape-encoded sequence within a URI, if there is potential for it to be incorrectly interpreted by the remote application. This conversion may be due to the position of the character or escape-encoded sequence within the URI. For example, %7e is sometimes used instead of ~ in an http URL path, but the two are equivalent for an http URL.
Because the percent % character always has the reserved purpose of being the escape indicator, it must be escaped as %25 in order to be used as data within a URI. The RFC for URI encoding recommends that care should be taken not to escape or un-escape the same string more than once, since un-escaping an already un-escaped string might lead to misinterpreting a percent data character as another escaped character, or vice versa in the case of escaping an already escaped string.
Useful Character Escape Code:
SPACE %20
%3C
%3E
%23
% %25
%7D
%7C
%5C
^ %5E
~ %7E
[ %5B
] %5D
%60
; %3B
/ %2F
? %3F
: %3A
@ %40
= %3D
& %26
$ %24
