Understanding URL Encoding
URL encoding (also known as percent-encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI) under certain circumstances. It is used to convert characters into a format that can be transmitted over the Internet.
URL encoding is necessary because URLs can only contain a limited set of characters (alphanumeric characters and a few special symbols). Other characters, such as spaces or special symbols, must be encoded to be safely transmitted in a URL.
