URL Encoding:

URL encoding is provided to convert non-ASCII characters into a format that can be used over the Internet because a URL is sent over the Internet by using the ASCII character-set only. If a URL contains characters outside the ASCII characters set, the URL has to be converted.

In URL encoding, the non-ASCII (American Standard Code for Information Interchange) characters are replaced with a “%” followed by hexadecimal digits.
