Instead of using FileWriter, create a FileOutputStream. You can then wrap this in an OutputStreamWriter, which allows you to pass an encoding in the constructor. Then you can write your data to that inside a try-with-resources Statement:

try (OutputStreamWriter writer =
             new OutputStreamWriter(new FileOutputStream(PROPERTIES_FILE), StandardCharsets.UTF_8))
    // do stuff
}

Try this

Writer out = new BufferedWriter(new OutputStreamWriter(
    new FileOutputStream("outfilename"), "UTF-8"));
try {
    out.write(aString);
} finally {
    out.close();
}

Try using FileUtils.write from Apache Commons.

You should be able to do something like:

File f = new File("output.txt"); 
FileUtils.writeStringToFile(f, document.outerHtml(), "UTF-8");

This will create the file if it does not exist.

var out = new java.io.PrintWriter(new java.io.File(path), "UTF-8");
text = new java.lang.String( src || "" );
out.print(text);
out.flush();
out.close();
