Corrupt keys might be printed as non-utf8 strings to the log,
and that, in turn, may break applications reading the logs,
such as Python (3.7)
For example:
```
Traceback (most recent call last):
File "/home/bhalevy/dev/scylla-dtest/dtest.py", line 1148, in tearDown
self.cleanUpCluster()
File "/home/bhalevy/dev/scylla-dtest/dtest.py", line 1184, in cleanUpCluster
matches = node.grep_log(expr)
File "/home/bhalevy/dev/scylla-ccm/ccmlib/node.py", line 367, in grep_log
for line in f:
File "/usr/lib64/python3.7/codecs.py", line 322, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb3 in position 5577: invalid start byte
