allow special characters in get method route laravel

I've a url similar like this:

GET: http://ift.tt/1RvYdd1

my route is:

Route::get('testroute', 'TestController@testFunction');

controller:

public function testFunction() {
    return Input::get('test');
}

When I trying the param

?title=data

ie, no special characters which returns the data. But with special characters which returns null.

I've searched on google and not found any better solution to solve this. Kindly help me :)
