Using special characters in photoshop

I would like to use the copyright character, which I can access through >edit ,then >special characters. The problem is how do I use it in photoshop? I have dragged it on the desktop, but photoshop does not read the file it is saved in. The character won't open in preview, so I can not format it. The photoshop shortcut key- option G does not work. Is there another way?
