Depends on your definition of "junk character".

Your "junk" could be someone else's actual language.

What are you trying to do that you think you need this?

My junk is other than English alphabets,numbers and special characters present on keyboard

What you can probably do is define a regex of allowed characters (or non-allowed characters, depending on your requirement), then check the string against it as shown below

C#

Regex myCheck = new Regex("^[a-zA-Z0-9]*$");
if (myCheck.IsMatch(myString)) 
{
  HandleNonAllowedcharacter();
}

Hope that helps
