UnicodeDecodeError when trying to build on non UTF-8 environment

[Fedalto]

Hi,

I got an UnicodeDecodeError trying to read README.rst when my locale was anything other than UTF-8.
I made a change to specify the encoding when opening the file. And also removed the unicode character on README.rst.

You can reproduce the error:

$ LC_ALL=C python3 setup.py build

Traceback (most recent call last):
  File "setup.py", line 21, in <module>
    ldesc = read_file('README.rst')
  File "setup.py", line 17, in read_file
    file_name
  File "/usr/local/Cellar/python3/3.4.3/Frameworks/Python.framework/Versions/3.4/lib/python3.4/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 7085: ordinal not in range(128)
