Those are Unicode objects, not traditional Python strings. Although
strings do have decode and encode methods, even in Python 2.3, the
former is shorthand for the construction of a Unicode object using the
stated encoding whereas the latter seems to rely on the error-prone
automatic encoding detection in order to create a Unicode object and
then encode the result - in effect, recoding the string.
As I noted, if one wants to remain sane and not think about encoding
everything everywhere, creating a stream using a codecs module
function or class will permit the construction of something which
deals with Unicode objects satisfactorily.
