Some character literals are treated as integers by Fernflower, as the
complement operator always evaluates to an integer, even if its operand
is a character. This is fine, but ComplementTransformer removes some
complement transformers - leaving integer literals where Fernflower
would normally insert a character literal.
This transformer converts complemented integers to char literals in some
cases where it makes sense (it is difficult to perform this
transformation across every type of expression in JavaParser).
