38.2.0 Breaks installs of several packages on 2.7 with UnicodeEncodeError parsing package METADATA

[mgrdcm]

Using setuptools==38.2.0 on Python 2.7.14, this setup.py will fail on any of the packages under install_requires with errors such as UnicodeEncodeError: 'ascii' codec can't encode character u'\u2013' in position 4258: ordinal not in range(128). None of these happened under 38.1.0 for instance. Error is happening on this line:

setuptools/setuptools/wheel.py

Line 59 in 97ff22f

return email.parser.Parser().parsestr(value)

from setuptools import setup, find_packages

setup(
    name="test-setuptools-encoding-problem",
    version="1.0.0",
    packages=find_packages(),
    install_requires=[
        "requests==2.18.4",
        "eventbrite==3.3.3",
        "django_mathfilters==0.4.0",
        "django-countries==5.0",
    ]
)

Verified it doesn't happen with Python 3.6.3 for instance.

Thanks for the report, expect a bug fix release soon.

Thanks @benoit-pierre! Let me know if I can help, for instance with testing.

@benoit-pierre Works great for me!

@benoit-pierre not sure if this is the right place but 38.2.0 also broke this:

install_requires = [
    'luma.core>=1.1.1',
    'rpi_ws281x;platform_machine=="armv7l" and platform_system=="Linux"',
    'ws2812;platform_machine=="armv7l" and platform_system=="Linux"'
]

Packages are always installed (not only for ARM) and not skipped.

[benoit-pierre]

OK, fix for original issue released in 36.2.1.

Thank you so much for the quick work @benoit-pierre!

@thijstriemstra: can you open a new issue with more info please?
