The PayPalURLEncoder java class percent encodes everything other than 'a-zA-Z0-9 _'. Then it converts ' ' to '+'. Ruby's CGI.encode takes care of the ' ' and '*' to satisfy PayPal
(but beware, URI.encode percent encodes spaces, and does nothing with '*'). Finally, CGI.encode does not encode '.-', which we need to do here.
