Lack of this parameter means that you may get an exception (if the incoming data is an invalid encoding) you can not get around.

This causes Twisted to be unable to provide a compatible API on Python 3.7.

Thanks for the report and the PR, @hawkowl!  Merged for 3.7.0rc1.

Is 'replace' the good default value? 'strict' is the default value for most encoding/decoding operations. 'surrogateescape' is used if the failure and the loss of information are not desirable (like in filenames decoding). 'backslashreplace' is good if we want to avoid a failure, but want to expose undecodable bytes in human-readable form.

This change mirrors the default in FieldStorage (which it calls). If it's not the best option, then it would need to be changed in FieldStorage too.

(personally, I don't like strict because UnicodeDecodeErrors on untrusted user input kind of sucks, but also replace is kind of broken as well.)
