Comment (by andrewgodwin):

 The original author is correct, CharFields are unique in their behaviour
 that the empty value for new NOT NULL instances is assumed to "", much
 like BooleanFields used to be False (but of course, that's the database
 default anyway).

 We should just modify the SchemaEditor to use "" as a default value if the
 field is stringable and NOT NULL. I'm pretty sure most code to do this
 already exists.
