The problem is more the fact that UTF-16 would require a stateful codec.

For the UnicodeWriter IMHO the best solution would be to make the csv 
module unicode transparent (i.e. it simply calls the write method of the 
underlying stream). Then it should be possible to stack the streams like 
this:

import csv, codecs

w = cvs.writer(codecs.getwriter("utf-16")(open("foo.csv", "wb"))
w.writerow([u"foo", u"bar")]

If csv was implemented in Python this would be trivial.
