Read .vbs files using java

[rohit2]

I am developing a tool using java swing. In it I have to read a .vbs file. I have used the following code for it.

Scanner fileReader1 = new Scanner(new File(fileName),"US-ASCII");

        while (fileReader1.hasNext())
        {
          System.out.println(fileReader1.nextLine());
         }

where fileName is valid .vbs file path

This is working only for .vbs files in my PC. For other systems, .vbs files are not opening. I think the problem is due the change in charset. For me it is "US -ASCII" and for others it may be "UTF 8" or "UTF 16". So how can I resolve this problem? My purpose is to open .vbs file using my tool for any systems. What I have to do for this? which charset will work for all systems ? please help.........
