URL Escaped Encoding Decoder 1.0

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

{ %7B

} %7D

| %7C

/ %5C

^ %5E

~ %7E

[ %5B

] %5D

` %60

; %3B

/ %2F

? %3F

: %3A

@ %40

= %3D

& %26

$ %24
