Is fileobj already given as open, or do you have a filename for it?
If the latter, just do

stream = codecs.open(filename, "w", encoding="utf-8")

If the former, do

writer = codecs.lookup("utf-8")[3]
# or
# enc, dec, reader, writer = codecs.lookup("utf-8")

stream = writer(fileobj)

An EncodedFile is not suitable since it has byte strings on both ends,
and Unicode strings only inside.
