Solution: add to the ObjectMapper configuration.

mapper.configure(FEATURE.ALLOW_UNQUOTED_CONTROL_CHARS,true);

More powerful, and other.

// Allow integer leads of the form 0,eg: "01"
            mapper.configure(Feature.ALLOW_NUMERIC_LEADING_ZEROS, true);
            mapper.configure(Feature.ALLOW_COMMENTS, true);
            mapper.configure(Feature.ALLOW_UNQUOTED_FIELD_NAMES, true);
            mapper.configure(Feature.ALLOW_SINGLE_QUOTES, true);
            mapper.configure(Feature.ALLOW_UNQUOTED_CONTROL_CHARS, true);
