No, this is wrong: you can see that it is importing "encodings"
from /usr/lib, instead of using the version within the executable.

The fact that it is not auto-imported does not seem a mistake per-se. I
don't think you should rely on the fact that, whenever you import
"encodings", "encodings.utf_8" gets automatically imported as well
(without having explicitly used utf-8 before).
What happens if you instead swap the last two lines in your sample
program, that is:
===========================================================
import encodings
def main():
print encodings
print dir(encodings)
print repr(u'\u2029'.encode('utf-8')) # swapped
print encodings.utf_8 # swapped
if __name__ == "__main__":
main()
===========================================================
Does it work now?
