You shouldn't need to with the ft2font extension code, because it uses
pycxx which has support for kwarg handling. Eg in the _image.cpp src
 Py::Object resize(const Py::Tuple& args, const Py::Dict& kwargs);
Py::Object
Image::resize(const Py::Tuple& args, const Py::Dict& kwargs) {
 _VERBOSE("Image::resize");
 args.verify_length(2);
 int norm = 1;
 if ( kwargs.hasKey("norm") ) norm = Py::Int( kwargs["norm"] );
 double radius = 4.0;
 if ( kwargs.hasKey("radius") ) radius = Py::Float( kwargs["radius"] );
 //snip snip snip
}
so you can easily add kwarg handling by changing the declaration to
accept a Py::Dict and then use the object with dictionary like
semantics. In the init_type function, you'll need to declare your
method as a kwarg method, eg
 add_keyword_method( "resize", &Image::resize, Image::resize__doc__);

It apparently has to be font.load_char(ch, LOAD_NO_SCALE), or at least
that produces width values that look similar to those in files saved
by Preview.app. But acroread still complains...
I hacked the load_char method to accept a "flags" keyword 
parameter. I hope I didn't break anything; is it safe to use
PyArg_ParseTupleAndKeywords with the C++ interface?
