The problem here to me is that the failure is input data dependent so
often hidden. There should be a way to remove this dependency on input data.
Is there any way to specify that implicit conversions raise an exception?
Perhaps by setting the default encoding to "undefined". Then these
developers can find and fix their bugs before delivery to customers.
