Well it's nearly clear that Python upstream will not accept this issue: they usually try to support the original national standard, not a w3c/whatwg web-standard. Python's codecs are quite pedantic,...

By Googling for "whatwg encoding python" I found an implementation for that standard called [webencodings](https://pypi.python.org/pypi/webencodings). ~~I haven't actually verified how well it works (or whether it works at all) though.~~...

I'm actually planning to change that opcode error lines to things like unknown opcode: %2x., (int) ins.opcode.
