How to make copyright symbol on the iPad?

as a photographer, i often need to tag photo with (C) scott nichol... there are several apps that i use that allow you to edit the metadata on photos and when the keyboard comes up, there doesn't seem to be any way to make the (C) character appear.

often there are hidden characters (accented letters, bullets, etc) that will pop up on the keyboard if you tap and hold certain keys. but non of the pop-up keys seem to contain the (C) symbol. has anyone found this character on a standard keyboard? is there a way to suggest this as feature for a future iPad update?

thanks,
scott nichol
