TTFQuery has a new release up. This release has a bunch of small breaking changes in it, specifically the command line demonstration tools now work differently. It also is now Python 3 ready (i.e. one more package should now be out of the way to get OpenGLContext running under Python 3) and finally has its own (basic) test-suite instead of relying on OpenGLContext to exercise it. It's also got a bit more documentation. You should be able to pull it with:
pip3 install 'ttfquery==2.0.0b1'
or, if you want to run the test suite (expect it to fail under Win32 or Mac, as I don't have those):
pip install tox
bzr branch lp:ttfquery
cd ttfquery
tox
Enjoy.
