One good example is:
Recoverable error: \xe5\x88\xa9\xe7\x94\xa8\xe5\x8f\xaf\xe8\x83\xbd\xe3\x81\xaa\xe3\x82\xb3\xe3\x83\xb3\xe3\x82\xbd\xe3\x83\xbc\xe3\x83\xab\xe3\x81\x8c\xe3\x81\x82\xe3\x82\x8a\xe3\x81\xbe\xe3\x81\x9b\xe3\x82\x93\xe3\x80\x82'
It is Japanese text, but even Japanese can read it without decoding.
It is hard for operators to understand :(
