UnicodeDecodeError: 'utf-8' codec can't decode byte 0xec in position 4: invalid continuation byte

[Ken Sharp]

I suspect the error may be down to a Python script, but I really don't know.

$ nyx -c /run/tor
Traceback (most recent call last):

    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xec in position 4: invalid continuation byte

I've no idea how to work around this.
