I guess that you mean a Python library? When you exchange with external programs or call a C libraries, Python is responsible to encode Unicode to bytes with os.fsencode(). The external part is not aware that Python uses surrogateescape, it gets "regular" bytes. I suggest to consider such Python library as external programs and libraries: convert Unicode to bytes with os.fsencode(), but also process paths as Unicode "inside" your application. It's the basic rule to handle correctly Unicode in an application: decode inputs as soon as possible, and encode back as late as possible. Encode/decode at borders.
