Read UTF-16 chars from a file and store them as UTF-8

I have a Person pojo, with a name attribute which I store in my database within the respective persons table. My db server is MySQL with utf-8 set as the default server encoding, the persons table is an InnoDB table which was also created with utf-8 as the default encoding, and my db connection string specifies utf-8 as the connection encoding.

I am required to create and store new Person pojos, by reading their names from a txt file (persons.txt) which contains a name in every line, but the file encoding is UTF-16.

persons.txt

etc..

Here is a sample code:

PersonDao dao = new PersonDao();
File file = new File("persons.txt");
BufferedReader reader = new BufferedReader(
                        new InputStreamReader(new FileInputStream(file), "UTF-16"));
String line = reader.readLine();
while (line!=null) {
    Person p = new Person();
    p.setName(line.trim());
    dao.save(p);
    line = reader.readLine();
}

To sum up, I am reading string characters as utf-16, store them in local variables and persist them as utf-8.

I would like to ask: Does any character conversion take place during this procedure? If yes, then at what point does this happen? Is it possible that I may end up storing broken characters due to the utf-16 -> utf-8 workflow?
