How to correctly display Russian words from the CMD.exe console using JAVA?

Question

Java

Greetings!
Friends, there is a simple (as I thought) task.
The java application is launched in the Windows console.
The application asks you to enter a string, after which it displays it next.
Everything would be fine, but I ran into a problem.
When I write a word in Cyrillic, it does not read the letter "SH" (large). It displays "?" instead.
I looked through the Internet, wherever I found, they write to replace the encoding on the input stream and on the output. I tried this and that, and cp866 and cp1251 encoding.
I achieved that the Cyrillic alphabet is displayed normally, everything except the letter Ш.
And, interestingly, the given line from the program displays correctly.
Friends, please help!
Or tell me how to fix it, or where to dig.

Below is the program code

public class Main {

    public static void main(String[] args) throws Exception {
  // write your code here
        System.out.println("Привет! Что ты хочешь, чтобы я вывел на экран консоли?");

        //подмена стандартного вывода другим потоком, который выводит в кодировке Cp866
        PrintStream systemOut = System.out;
        PrintStream printStream = new PrintStream(System.out, true, "Cp866");
        System.setOut(printStream);

        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        String userText;
        String data = reader.readLine();
        while (!"exit".equals(data)) {
            userText = data;
            //вывод в консоль слова в кодировке Cp866
            String text = "вывожу на экран (а букву Ш покажу как ?) >";
            System.out.print(text);
            System.out.write(userText.getBytes());

            System.out.println("\nЧто-то еще хочеШь написать? <or exit>");
            data = reader.readLine();
        }
        printStream.close();
        reader.close();
        System.setOut(systemOut);
        System.out.println("Пока! ШШШШШ");
    }
}
