I'm surprised at this. Just unicode(input) is never going to work and in 
that case it doesn't work in plain Zope 3 either, which would be a surprise.

What I'd expect is that something in Zope 3 (the publisher?) converts 
(likely UTF-8) input to unicode; I'm not sure why the widget is doing 
another unicode().

What needs to be done in our case, I guess, is a unicode(input, 
ask_zope_for_default_encoding_in_this_context())

What is happening on output?
