Parse error on UTF8 domain-reports

[ppKrauss]

Example pwhois -j terra.com.br (or pwhois -r terra.com.br)

Traceback (most recent call last):
  File "/usr/local/bin/pwhois", line 23, in <module>
    data, server_list = pythonwhois.net.get_whois_raw(args.domain[0], with_server_list=True)
  File "/usr/local/lib/python2.7/dist-packages/pythonwhois/net.py", line 44, in get_whois_raw
    response = whois_request(request_domain, target_server)
  File "/usr/local/lib/python2.7/dist-packages/pythonwhois/net.py", line 94, in whois_request
    return buff.decode("utf-8")
  File "/usr/lib/python2.7/encodings/utf_8.py", line 16, in decode
    return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xe7 in position 1278: invalid continuation byte
