Perhaps your computer has a problem. Mine does this with both Python
2.7 and Python 2.3 (which introduced the unicodedata.normalize
function):

  >>> import unicodedata
  >>> t1 = u"abcd\xa1"
  >>> t2 = unicodedata.normalize('NFD', t1)
  >>> t3 = t2.encode('ascii', 'replace')
  >>> [t1, t2, t3]
  [u'abcd\xa1', u'abcd\xa1', 'abcd?']
  >>> map(len, _)
  [5, 5, 5]
  >>>
