This version looks much better. In StringCoding, do you really need 
throwCCE? The encode/decode methods do a replace or throw so I assume 
one flag will do. If combined with Sherman suggestion then it would be 
minimal changes to StringCoding. It would be nice to get rid of the IAE 
completely but that is for another day. In Files then you don't need to 
check if cause is null before testing its type.

The update tests to check for UnmappedCharacterException and 
MalformedInputException look good.
