Answer 1

Instead of using FileReader, use InputStreamReader and pass the charset.

Example:

BufferedReader br2 = new BufferedReader(
                         new InputStreamReader(new FileInputStream(getNomeArquivo()), "UTF8"));

Answer 2

File arq = new File(nomeArq);

// para ler
BufferedReader leitor = new BufferedReader(new InputStreamReader(new FileInputStream(arq.getPath()), "ISO-8859-1"));

// para escrever
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(arq.getPath()), "ISO-8859-1"));
