In lxml, there was an "encoding=unicode" option that would let the XML/HTML/text serialisation function return a Unicode string. This was eventually deprecated in favour of "encoding='unicode'" when ElementTree gained this feature as well some years later. That's this issue: http://bugs.python.org/issue8047 The thread also suggests the options encoding=False and encoding=None Considering ET uses encoding="unicode" to signal 'don't encode', I agree with you that using encoding="bytes" to signal 'don't encode' would be sensible. However, ET /also/ allows encoding=str.What about allowing both encoding="bytes" /and/ encoding=bytes?

It doesn't read well for the unicode type any more because it's gone in Py3 (and "encoding=str" just looks weird). It's less awkward for the bytes type.

However, why should there be two ways to do it?
