Expand © and remove unnecessary encoding lines

The word "Copyright" alone is sufficient to claim copyright, the ©
symbol need not be present.[1] This allows us to expand the "©" symbol
into "(c)" to avoid introducing non-ASCII characters.

As per PEP 263, a Python file with non-ASCII characters must have a
line with "coding: <some-encoding>". Python files containing only
7-bit ASCII characters need no such line.[2]

This commit expands the non-ASCII Unicode copyright symbols and
removes the now unnecessary encoding lines.
