Unicode parsing problems#28

Looking up some IP addresses seems to lead to an UnicodeDecodeError: ``` >>> pythonwhois.get_whois('179.175.242.131') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/fsufitch/python-whois/pythonwhois/__init__.py", line 4, in get_whois raw_data, server_list = net.get_whois_raw(domain, with_server_list=True) File "/home/fsufitch/python-whois/pythonwhois/net.py", line 42, in get_whois_raw response = whois_request(request_domain, target_server) File "/home/fsufitch/python-whois/pythonwhois/net.py", line 92, in whois_request return buff.decode("utf-8") UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd4 in position 565: invalid continuation byte ``` Also: ``` >>> pythonwhois.get_whois('80.148.135.28') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/fsufitch/python-whois/pythonwhois/__init__.py", line 8, in get_whois return parse.parse_raw_whois(raw_data, normalized=normalized, never_query_handles=False, handle_server=server_list[-1]) File "/home/fsufitch/python-whois/pythonwhois/parse.py", line 553, in parse_raw_whois data["contacts"] = parse_registrants(raw_data, never_query_handles, handle_server) File "/home/fsufitch/python-whois/pythonwhois/parse.py", line 894, in parse_registrants contact = fetch_nic_contact(data_reference["handle"], handle_server) File "/home/fsufitch/python-whois/pythonwhois/parse.py", line 981, in fetch_nic_contact response = net.get_whois_raw(handle, lookup_server) File "/home/fsufitch/python-whois/pythonwhois/net.py", line 42, in get_whois_raw response = whois_request(request_domain, target_server) File "/home/fsufitch/python-whois/pythonwhois/net.py", line 92, in whois_request return buff.decode("utf-8") UnicodeDecodeError: 'utf-8' codec can't decode byte 0xdf in position 706: invalid continuation byte ``` More IPs that break in this way: - 177.169.129.223 - 80.148.135.28 - 181.1.55.141 - 91.6.97.224 - 179.246.105.144 - 94.92.58.77 I ran into this while testing a separate program on completely random IPs. To reproduce: ``` import ipaddress, random, traceback import pythonwhois randip = lambda: ipaddress.ip_address(random.randint(0,256**4-1)).compressed for i in range(50): ip = randip() try: pythonwhois.get_whois(ip) except UnicodeDecodeError as e: print('========', ip, '========') traceback.print_exc() except Exception as e: continue ``` Thanks!
