You might as well write "(<)" or "[C]". Neither is a copyright mark an
any sense of the law, and using it does not do anything else than
informing the reader that you claim the rights - you already have the
rights even if you don't write anything. If you can only use ASCII,
the "most proper" way would be to spell out "Copyright", but that is
also just for information. As you can see, your example is using both
forms.
