URL Encode/Decode

URL encoding is the process of substituting particular characters in a URL with one or more character triplets, which are made up of the percent character "%" followed by two hexadecimal numbers. The numeric value of the replacement character is represented by the two hexadecimal digits of the triplet(s). URL decoding is the reversed way of encoding, exchanging the replaced characters with Latin originals.

A two-step technique is required to map the huge range of characters used throughout the globe into the 60 or so allowable characters in a URL:

Which Characters Are Allowed in URL Encode/Decode?

The characters that can be used in a URI are classified as reserved or unreserved (or a percent character as part of a percent-encoding). Reserved characters are ones that have a specific meaning on occasion, whereas unreserved characters do not. Characters that would normally be forbidden are represented by authorized characters when employing percent-encoding. With each version of the standards that govern URIs and URI schemes, the sets of reserved and unreserved characters, as well as the situations under which particular reserved characters have special significance, have altered slightly.

The characters in a URL must come from a defined set of unreserved and reserved ASCII characters, according to RFC 3986. A URL cannot include any additional characters.

The characters that aren't reserved can be encoded, but they shouldn't be. The characters who are unreserved are:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z a b c d e f g h i j k l m n o p q r s t u v w x y z 0 1 2 3 4 5 6 7 8 9 - _ . ~

Only in rare cases are reserved characters need to be encoded. The following characters are reserved:

! * ' ( ) ; : @ & = + $ , / ? % # [ ]
