1. Blank characters
   Blank characters, empty characters, invisible characters and whitespace characters. they appear sort of a space, but are actually a special (unicode) character. they will be used if you would like to represent an blank or empty space without using space. for instance you would like to use an empty value during a website or application, but spaces aren't accepted. For this example you'll use one among the characters on this site. for instance, sending an empty message, or setting a form value to blank. If the appliance filters out other unicode characters then the characters on this site won't work.
