FileOutputStream is meant to be used to write binary data. If you want to write text you can use a FileWriter or an OutputStreamWriter.
FileOutputStream 旨在用于写入二进制数据。如果要编写文本，可以使用 FileWriter 或 OutputStreamWriter。
Alternatively you could use one of the methods in the Filesclass, for example:
另外，您可以使用的方法之一的Files类，例如：
Path p = Paths.get(ismmilaf);
Files.write(p, moarif1.getBytes(StandardCharsets.UTF_8));

You need to use OutputStreamWriterso you can specify an output charset. You can then wrap that in a PrintWriteror BufferedWriterif you need printing semantics:
您需要使用，OutputStreamWriter以便可以指定输出字符集。然后，您可以将其包装在 a PrintWriterorBufferedWriter如果您需要打印语义：
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();

That is because you are using different charsetand those characters do not belong to that, could you try using UTF-8, e.g.:
那是因为您使用的是不同的charset并且这些字符不属于该字符，您可以尝试使用UTF-8，例如：
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 can specify it as the third param of PrintStream like this:
您可以将其指定为 PrintStream 的第三个参数，如下所示：
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:
或者使用 StandardCharsets.DesiredEncoding （我记不太清楚了，但也许你需要在它上面使用 .toString() ，比如：
stream = new PrintStream(foostream, true, StandardCharsets.UTF-8.toString());
