Answer 1

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();
