Yes, I am or was confused. I'm thinking a String is just a collection of characters which are just collections of bytes, and once the String is created it should hold anything a byte array can hold and the control needs to know how to display it. Apparently it's the font that needs to know how to display it. So, I don't know how Notepad++ comes up with their codes to show what non-displayable characters look like, but if the Font has a method to say the character can't be displayed I'll just go with displaying a placeholder, most likely a dot (".") and show the value of the position in hex. I have code here somewhere to convert bytes to hex.
