Those bytes could be UTF-8, UTF-16, UTF-32, or any of a number of other possible encodings[1]. If you get the internal byte stream, there's no way to meaningfully operate on it unless you also know how it's encoded (or you're willing to sacrifice the ability to reliably get the string back). -tkc [1] http://docs.python.org/library/codecs.html#standard-encodings
