Description: Replace the copyright sign by ASCII chars
 The tests
  tests/test_wsdl_arrays.py
  tests/test_wsdl_messages_rpc.py
 are failing in an sbuild environment with 
 UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 89: ordinal not in range(128)
 while they succeed without error in the GitHub CI as well as in a local 
 virtual environment with tox.

 While investigating further this patch replaces for now the offending char.
