It strikes me that this is just a bug, and that we should just fall back from UTF-8 to latin-1 in this scenario.  But adding that fallback is a small additional fix (perhaps one that should be slated for 16.6.0 if you want to make it).

Yeah, this is just a plain old bug. Bugs in new features (where a module being on Python 3 counts as one to me) aren't regressions; we sometimes fix them in pre if there's time/other stuff is getting fixed, but this one will just be a known bug until 16.7 in December.
