Unfortunately Python 3.2 doesn't understand the u-prefixed syntax for
unicode strings. Are the strings in english_words all unicode? Then
dictionary = io.StringIO("\n".join(english_words))
should work. In Python 3 "\n" is unicode anyway, and Python 2 implicitly
converts "\n" to unicode:
$ python
Python 2.7.6 (default, Mar 22 2014, 22:59:56)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> "\n".join([u"foo", u"bar"])
u'foo\nbar'
