Thank you all for the review.

In CharacterSetFilterReader, maybe remove private static final HashSet<Integer> EMPTY_SET = new HashSet<>(0); ? And perhaps use Collections.emptySet() ?

Yes, good catch.

Also in CharacterSetFilterReader, I think it could be dangerous just using the collection provided by the user. Maybe create a new field using Collections.unmodifiableSet(originalSet) ?

Yes, good catch.

Yes, this solution is broader but simpler for the case of CSV-222 IMO. I like it because it does not make the CSV lexer more complex.
