1. Does Python offer any assistance in doing so, or do you have to
manually convert the surrogates which are generated for unrecognised bytes?

2. How do you do this for non-invertible encodings (e.g. ISO-2022)?

Most of the issues can be worked around by calling
sys.setfilesystemencoding('iso-8859-1') at the start of the program, but
sys.argv and os.environ have already been converted by this point.
