Glad to hear that.

I ruled that out by lookup up the descriptor.
It took me a while to find that descriptor on collector that is why I
linked it in my last email:

>>> descriptor containing that platform string: 
>>> https://collector.torproject.org/recent/relay-descriptors/server-descriptors/2016-07-07-06-05-14-server-descriptors

Yes, both relays on that IP  (same ORPort), changed from "Tor 0.2.7.6 on
Windows 8" to that non-ASCII string (that is why I knew he is probably
running Windows 8).
