Here's a word you may not know...
special characters
In the world of technology, special characters are known as the characters on a computer keyboard (although not restricted to just the characters on a keyboard) other than a-z (lowercase), A-Z (uppercase) and 0-9. Examples of special characters are !, #, &, " and +.
