I suspect there is a problem with Test 6/6 of this challenge. Instead of checkio("04704072126132480B42F66E6AF67572205E5F5E"), it should be checkio("04704072126132480D42C3B66E6AC3B67572205E5F5E"). You will see in the commands in the Python console in the attached screenshot that, as is, the รถ is misencoded as '\xf6', when in fact it needs to be '\xc3\xb6' according to the utf-8 standard.
