Problems with Java Strings

Question

Guys, I’m running a data migration from a csv file to an H2 database. In this process I use the beanio to read the file and transform it into objects and then persist the objects in the base using jpa+Hibernate.

The problem is weird because when reading the file the description property of the first object read is

Does anyone have any idea what this is?

Excerpt from the code that parses and saves to db

StreamFactory factory = StreamFactory.newInstance();
        // load the mapping file
        factory.load(resourcePath_beanio + tabelaArquivo[0].toLowerCase() + ".xml");

        //create reader
        BeanReader in = factory.createReader(tabelaArquivo[0].toLowerCase(), new File(tabelaArquivo[1]));
        Object  entity;

        //list of details
        Set<Object> entities = new HashSet<>();

        //add details to list
        while ((entity = (Object) in.read()) != null) {
            entities.add(entity);

        }

        Class<AbstractDAO<Object, Long>> dao = (Class<AbstractDAO<Object, Long>>) Class.forName(packageRoot_dao + tabelaArquivo[0] + "DAO");

        Ambiente.getInstance().setBatch();

        //save details on DB
        dao.newInstance().saveAll(entities);
