URL Decoding
All responses to HTTP POST operations used by the PayPal NVP API must be decoded.
The PayPal NVP API uses the HTTP protocol to send requests and receive responses from a
PayPal API server. You must decode all data returned using the HTTP protocol so that it can
be displayed properly. Most programming languages provide a way to decode strings.
NOTE: Most browsers decode responses to HTTP requests automatically.
