Encoding in XML declaration python

Question

I have created an XML file using python. But the XML declaration has only version info. How can I include encoding with XML declaration like:

Answer 1

>>> from xml.dom.minidom import Document
>>> a=Document()
>>> a.toprettyxml(encoding="utf-8")
'\n'

or

>>> a.toxml(encoding="utf-8")
''

you can set the encoding for the document.writexml() function in the same way.
