You can do it all with TIdURI:

• To decode use TIdURI.URLDecode(...).
• To parse, pass the decoded URI to TIdURI.Create.

Putting it together you'd have something like this:

var
  URI: TIdURI;
....
URI := TIdURI.Create(TIdURI.URLDecode(EncodedURI));
try
  // Protocol = URI.Protocol
  // Username = URI.Username
  // Password = URI.Password
  // Host = URI.Host
  // Port = URI.Port
  // Path = URI.Path
  // Query = URI.Params
finally
  URI.Free;
end;
