copyright symbol definition character, legal
"©" The internationally recognised symbol required to introduce a copyright
notice, a letter C with a circle around it. This can be encoded in ISO 8859-1
as character code decimal 169, hexadecimal A9, in HTML
as ©, © or ©.
A "c" in parentheses: "(c)" is sometimes used in documents stored in a coded character set
such as ASCII
that does not include the C in a circle, but this has no legal meaning.
