What assumption are you making there, using the inverse?

Chars in 'hull' are 'maybes' aren't they?
a set of characters that may be in the repertoire
I guess I'm assuming kernel+hull+unknown=repertoire. Perhaps that
isn't a valid assumption.

+1 I'm OK on that part.
but if there is a <hull>

So the repertoire isn't bounded / complete then.
