You've been given the right answer by the other participants but 
I'd like to share this simple helper range from my user lib:

auto nullTerminated(C)(C c)
if (isPointer!C && isSomeChar!(PointerTarget!(C)))
{
     struct NullTerminated(C)
     {
         private C _front;
         ///
         this(C c)
         {
             _front = c;
         }
         ///
         @property bool empty()
         {
             return *_front == 0;
         }
         ///
         auto front()
         {
             return *_front;
         }
         ///
         void popFront()
         {
             ++_front;
         }
         ///
         C save()
         {
             return _front;
         }
     }
     return NullTerminated!C(c);
}

The idea is to get rid of the conversion and to process directly 
the pointer in all phobos function.
