font selection doesn't work

[mcepl]

I have two questions. First of all, what about this one (using rst2odp 0.3.1):

matej@mitmanek: PyCon18-m2crypto (master *%)$ rst2odp --traceback --template-file=urania_black.otp --font='Urania Czech' --mono-font=Incosonlata slides.rst slides.odp
Traceback (most recent call last):

    u'fo:font-family="%s"' %NORMAL_FONT)
TypeError: 'str' does not support the buffer interface

And the second, what is the name of the relevant section in docutils.cnf? [odf_odp writer]?
