I'm writing a very simple and small example class to try and show how the .getCurrencyInstance() of the NumberFormat class in Java works, but my output is looking a little funky. It seems the class is working, but when it tries to print out the actual symbols for currency (like the Japanese yen symbol or the British pound symbol) I get weird symbols instead. Is there any way to fix this? Is there something I need to import to get these symbols on my computer?

Here's my code:

import java.util.*;
import java.text.*;

public class CurrencyFormatExample
{
   public static void main(String[] args)
   { 
      double convert = 9398.9398;

      NumberFormat currencyFormat = NumberFormat.getCurrencyInstance();
      System.out.println("American: " + currencyFormat.format(convert));

      Locale swedish = new Locale("sv", "SE");
      NumberFormat swedishFormat = NumberFormat.getCurrencyInstance(swedish);

      System.out.println("Swedish: " + swedishFormat.format(convert));

      Locale japanese = new Locale("ja", "JP");
      NumberFormat japaneseFormat = NumberFormat.getCurrencyInstance(japanese);

      System.out.println("Japanese: " + japaneseFormat.format(convert));

      Locale russian = new Locale("ru", "RU");
      NumberFormat russianFormat = NumberFormat.getCurrencyInstance(russian);

      System.out.println("Russian: " + russianFormat.format(convert));

      Locale british = new Locale("en", "GB");
      NumberFormat britishFormat = NumberFormat.getCurrencyInstance(british);

      System.out.println("British: " + britishFormat.format(convert));
   }
}

Here is the output I get with this:

American: $9,398.94
Swedish: 9á398,94 kr
Japanese: ?9,399
Russian: 9á398,94 ???.
British: ú9,398.94

As you can see that's clearly not right. Any way I can remedy this?
