Title: Fix Cairo text on Python3 with pycairo

There are three possible cairo wrappers that we support: `py2cairo` on Python 2.x, `pycairo` on Python 3.x and `cairocffi` on both. Unfortunately, they want to receive strings differently. `py2cairo` expects them as utf-8-encoding byte strings. The other two expect Python unicode strings.

This fixes the one case we missed in the recent changes to support cairocffi: when on Python 3.x with pycairo, we need to give the wrapper unicode strings.

Replaces #2905. Fixes #2903.
