Martin Geisler d7054053ae Remove (c) and remove unnecessary encoding lines
The word "Copyright" alone is sufficient to claim copyright, the (c)
symbol need not be present.[1]

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 removes unnecessary Unicode copyright symbols and
unnecessary encoding lines.
