It is not working fine on Python 3.3.0.
>>> with codecs.open('/tmp/test.txt', 'w', encoding='iso-8859-1') as f:
... xml = XMLGenerator(f, encoding='iso-8859-1')
... xml.startDocument()
... xml.startElement('root', {'attr': u'\u20ac'})
... xml.endElement('root')
... xml.endDocument()
...

And shouldn't. On Python 2 XMLGenerator works only with binary files and
"works" with text files only due implicit str->unicode converting. On Python 3
working with binary files was broken. Issue1470548 restores working with binary
file (for which only XMLGenerator can work correctly), but for backward
compatibility accepting of text files was left. The problem is that there no
trustworthy method to determine whenever a file-like object is binary or text.
Accepting of text streams in XMLGenerator should be deprecated in future
versions.
