That may not be true.  I compared 2.7 and py3k versions and the later
has some new features:

* unidata_version  changed from 5.2.0 to 6.0.0
* Unihan data is read from zip file
* added processing of DerivedCoreProperties

These changes don't affect gencodec.py, but it may be inconvenient to
run makeunicodedata.py and gencodec.py using different versions of
Python.

I'll check that all non-mac encodings are correctly generated before committing.
