UnicodeEncodeError using astropy.units.cds

See original GitHub issue

The following two scripts fail for me at the Python 2.7.12 command line using AstroPy 1.2.1:

import astropy.units.cds
help(astropy.units.cds)

and

import astropy.coordinates
import astropy.units.cds
astropy.units.cds.enable()
astropy.coordinates.Angle("5d")

The former fails with:
