Alas, I think you've run into one of the weaknesses of doctest. Don't get
me wrong, I am a huge fan of doctest, but it is hard to write polyglot
string tests with it, as you have discovered.
However, you may be able to get 95% of the way by using print.
def func(a):
"""
>>> print(func(u'aaa'))
aaa
"""
return a
ought to behave identically in both Python 2 and Python 3.3, provided you
only print one object at a time. This ought to work with both ASCII and
non-ASCII (at least in the BMP).
