[IPython-dev] No displayhook triggered for raw 'asdf'

Just to add to that, trying it in qtconsole, it gives the continuation

In [0]: "hi"

Also, I don't know if it's useful information, but I just updated IPython 3k
from master, and I can't replicate this in either the terminal or the
qtconsole. So perhaps it's tied to character encoding somehow.
