Fix problems with optional parsing due to Unicode strings in setup.py.
Review Request #9689 — Created Feb. 21, 2018 and submitted — Latest diff uploaded
The recent change to use Unicode strings in setup.py was failing on
Python 2 due to option parsing expecting Unicode strings. This change
fixes these up to use the native string type on each Python version.
Tested running
setup.py developon Python 2.7, 3.4, 3.5, and 3.6.
