URL encoding converts characters into formats that can be transmitted over the Internet.
URL Encoding
URLs can only be sent over the Internet using the ASCII character set.
Because the URL usually contains characters other than the ASCII set, the URL must be converted to a valid ASCII format.
The URL encoding uses "%" followed by two hexadecimal numbers to replace non-ASCII characters.
The URL cannot contain spaces. The URL encoding usually uses + to replace spaces.
