Laravel: Route not found error:

I am writing code for email verification and My url is being generated as:

http://ift.tt/1LxdMy5

I am using urlencod to encode it after base64 and I am getting Not Found Exception for the route because of % sign in it. Route is defined as:

Route::get(
    'auth/verify/{confirmation_code}',

How to resolve it? How can I make % sign acceptable?
