Python/compile.c:makecode() filename = PyStringFromString(c->cfilename); Modules/pyexpat.c:getcode() filename = PyStringFromString(FILE); Objects/codeobject.c:codenew() PyArgParseTuple(args, "iiiiiSO!O!O!SSiS|O!O!:code" As I tried to explain earlier that may be a problem. PyUnicodeDecode() doesn't work so early. The codecs package isn't initialized yet.

But some codecs are "built-in" and have custom APIs. I wonder if we could do something that figures out the default fs encoding, and see if it is one of the supported ones, and then uses that; otherwise tries UTF-8 with the "replace" error handling option (so it won't fail if the data is non-UTF-8).
