Searching for special characters

[georgiboy]

So.... everything between the first and last curly brackets is simply special characters being defined?

Yes the below:
{"!","@","#","$","%","^","&","~*","(",")","_","+","=","{","}","[","]","|","",":",";","'","""","<",">",",",".","~?","/","~~","`"}

Is simply an array of values, the curly brackets denote an array.
