Peer client UnicodeDecodeError

[Calum]

User reported peers not displaying for certain torrents:

 File "/usr/lib/python3.7/site-packages/deluge/core/torrent.py", line 813, in get_peers
     client = decode_bytes(peer.client)
 UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb5 in position 0: invalid start byte

This seems to be an upsteam libtorrent issue when peer client strings are not utf8 encoded:

That's the micro sign, probably somebody is using utorrent. Isn't the standard to use unicode internally?
