Some encoding issue with python3 version of snmph_from_cred_id function?

The information is the same from Python2 to 3. Python3 strings are unicode and so all those code points can be represented by utf-8 characters which is what you are seeing. I think it might be best to do something like... answer[0][1].encode("utf-8").hex(). This will push the string into bytes and then show the hex of the entire output.
