Why does my output give weird characters?

Question

import java.util.Scanner;
public class SDTester{
     public static void main(String[] args){
          String message;
          Scanner scan = new Scanner(System.in);
          BinarySearchTree t = new LinkedBinarySearchTree();
          System.out.println("Enter command");
          message = scan.nextLine();
}Can someone explain why my output for this when typing quit is:
Enter command
quit�:

Yeah its what I typed in. The "a" is not the only mysterious part. Theres also that upside down L type thing and the colon. Sometimes theres extra letters. Im running on windows vista.
Its weird when I copy the output some of the "weird" characters dont show up.
EDIT: Its only with inputted text. I did a simple println statement and it was fine but the quit when typed in and the quit when printed out from the variable "message" give the weird text:
