This is due to bare use of the `bytes` constructor to convert a string. The [docs](https://docs.python.org/3.6/library/functions.html#func-bytearray) for `bytes` refer to `bytearray` which states \"If it is a string, you must also give the encoding\".\r\n\r\nFor `-n`, the comparison is the only place that `self.name` is used, so I moved the the conversion to the `__init__` method. For `-f`, the compared `msg` is already a string (because `self.python_format` is a string), so the conversion is unnecessary.\r\n\r\nI've also made some minor cleanups such as removing redundant backslashes and semicolons.ghprbCommentBodynullghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="Fix bytes - strings confusion in trace tool" href="https://github.com/iovisor/bcc/pull/3277">PR #3277</a>: Fix bytes - strings confusi...#85211601867460664bcc-pr #852852false8526825SUCCESS1613997386336https://buildbot.iovisor.org/jenkins/user/davemarchevsky/my-views/view/all/job/bcc-pr/852/git852https://buildbot.iovisor.org/jenkins/user/davemarchevsky/my-views/view/all/job/bcc-pr/label=fc25/852/852https://buildbot.iovisor.org/jenkins/user/davemarchevsky/my-views/view/all/job/bcc-pr/label=fc26/852/852https://buildbot.iovisor.org/jenkins/user/davemarchevsky/my-views/view/all/job/bcc-pr/label=fc27/852/852https://buildbot.iovisor.org/jenkins/user/davemarchevsky/my-views/view/all/job/bcc-pr/label=fc28/852/852https://buildbot.iovisor.org/jenkins/user/davemarchevsky/my-views/view/all/job/bcc-pr/label=ubuntu1604/852/852https://buildbot.iovisor.org/jenkins/user/davemarchevsky/my-views/view/all/job/bcc-pr/label=ubuntu1710/852/852https://buildbot.iovisor.org/jenkins/user/davemarchevsky/my-views/view/all/job/bcc-pr/label=ubuntu1804/852/
