What is URL Encoding?

URL Encoding or Percent Encoding is a process of encoding certain special characters or unprintable characters like “Space” by replacing them with valid URL format to make it universally accepted by the web browsers.

 

Which Special Characters are Allowed in a URL?

According to several sources, the characters that are allowed in a URL are either reserved or unreserved. Besides these two, any other character is not allowed in a URL. Now understand the meaning of Reserved and Unreserved characters.

Reserved Characters:

Reserved characters are the letter or symbols that are used for a specific purpose. In other words, characters like “\, / * are reserved by Operating System and can’t be used while saving a file., :, and,

If used in URLs, these characters have a possibility of being misunderstood by certain reasons. When reserved characters are not used for special purpose within a URL, they need to be encoded.

Why we need URL Encoding/Decoding?

As we have already discussed that URL Coding or Percent coding is used to translate reserved or unreserved characters into a special format that can be sent over the internet. URLs made with ASCII (American Standard Code for Information Interchange) characters set are only accepted by servers or web browsers. But URLs are often designed with the characters outside ASCII set.

What is ASCII code?

ASCII is a abbreviation of American Standard Code for Information Interchange. It was designed as first character set used for computers over internet. Basically ASCII is a 7-bit character set that contain total 128 characters: numbers from 0 to 9, uppercase english letters from A to Z, lowercase english letters from a to z, and some special characters including space, !     “    #     $     %     &     ‘     (     )    *    +    ,    /    . and,  -. The characters that are used in HTML language and, modern computers are all based on ASCII character set.
