[C++-sig] Creating a unicode instrance from utf-8 encoded string

try

result.append(object(handle<>(PyUnicode_FromString(i->c_str()))));

The handle<> is a way to tell Boost.Python if you own the reference or if it is 
borrowed (among other things). The
suggested code assumes you own the reference.
