You can specify it as the third param of PrintStream like this:

foostream = new FileOutputStream(file, true);
stream  = new PrintStream(foostream, true, "UTF_8");
stream.println("whatever");

or using StandardCharsets.DesiredEncoding (i didn't remember it well but maybe you need to use .toString() on it, like:

stream  = new PrintStream(foostream, true, StandardCharsets.UTF-8.toString());

That is because you are using different charset and those characters do not belong to that, could you try using UTF-8, e.g.:

FileOutputStream fos = new FileOutputStream("G://data//123.txt");
        Writer w = new BufferedWriter(new OutputStreamWriter(fos, StandardCharsets.UTF_8));
        String stringa = "L’uomo più forte";
        w.write(stringa);
        w.write("\n");
        w.write("pause");
        w.write("\n");
        w.flush();
        w.close();

You need to use OutputStreamWriter so you can specify an output charset. You can then wrap that in a PrintWriter or BufferedWriter if you need printing semantics:

PrintWriter kitaba1 = null;

try {
   kitaba1 = new PrintWriter(new OutputStreamWriter(new FileOutputStream(new File(ismmilaf), true), StandardCharsets.UTF_8));

} catch (FileNotFoundException ex) {
    ex.printStackTrace();
}

//kitaba1.println(moarif1);
kitaba1.close();


BufferedWriter kitaba1 = null;

try {
   kitaba1 = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(new File(ismmilaf), true), StandardCharsets.UTF_8));

} catch (FileNotFoundException ex) {
    ex.printStackTrace();
}

//kitaba1.write(moarif1);
//kitaba1.newLine()
kitaba1.close();

FileOutputStream is meant to be used to write binary data. If you want to write text you can use a FileWriter or an OutputStreamWriter.

Alternatively you could use one of the methods in the Files class, for example:

Path p = Paths.get(ismmilaf);
Files.write(p, moarif1.getBytes(StandardCharsets.UTF_8));
