building with python3 fails due to unhandled Unicode characters in README.rst

[rathann]

When building colorspacious-1.0.0 using python-3.5.2, I get the following traceback:

/usr/bin/python3 setup.py build
Traceback (most recent call last):
  File "setup.py", line 11, in <module>
    LONG_DESC = open("README.rst").read()
  File "/usr/lib64/python3.5/encodings/ascii.py", line 26, in decode
    return codecs.ascii_decode(input, self.errors)[0]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 2025: ordinal not in range(128)

Here's one way of fixing this that works with both python2 and python3:

diff -up colorspacious-1.0.0/setup.py.orig colorspacious-1.0.0/setup.py

How about:

with open('README.rst', 'rb') as f:
    LONG_DESC = f.read().decode('utf-8')

?

That works just as well, thanks.
