Why encode a URL?
URLs can only contain certain ASCII characters. Spaces, accented characters, Asian characters and special symbols must be transformed into %XX sequences (percent-encoding) to be transmitted correctly over HTTP.
4 encoding methods

+(application/x-www-form-urlencodedstandard) - Custom: precisely choose which characters to preserve
