On Windows, distutils doesn't correctly read UTF-8 content from config files (setup.cfg).

Seems like the issue is located on the line reading the files via the ConfigParser; simply adding 'encoding="UTF-8"' as argument fixes the problem for me: https://github.com/python/cpython/pull/4727

On Linux it seems to be working fine.

Can you give an example setup.cfg file, setup.py command and the full error message?

I've attached the files.

Run using 'python setup.py sdist'.
The resulting PKG-INFO will contain incorrect data:

Summary: délivrance
Author: Dan Tès

The expected output is:

Summary: délivrance
Author: Dan Tès

`metadata` in setup.cfg is not supported directly by distutils.  Can you provide a setup.py script that shows the problem without setuptools?

The fix shall go to

https://github.com/python/cpython/blob/2812d3d99287c50bab99625d7240bcf1c2e32369/Lib/distutils/dist.py#L406

where `parser.read(filename)`

shall be changed to `parser.read(filename, encoding="utf-8")`

This assumes that the setup.cfg shall be UTF-8 encoded what I thing is correct assumption.

Alternative assumptions are (and I do not find them good):

- assume the file is encoded as current console is (this is not deterministic and is direct cause of this issue)
- let user to specify the encoding somewhere around (this requires extra step and does not bring any value)

Repeat: `metadata` in setup.cfg is not supported directly by distutils.  Can you provide a setup.py script that shows the problem without setuptools?

In my opinion, 'setup.cfg' is setuptools stuff and not part of python project. Anyway I think it is a good idea to read it as UTF-8.

Setuptools seems to be defaulting to UTF-8: https://github.com/pypa/setuptools/pull/1735

Hi,

I have closed the PR because there is no feedback from deliverance and the CLA must be signed for the processing. Once the CLA will be signed, the PR could be re-opened.

Thank you so much,

No, setup.py and setup.cfg are invented by distutils and extended by setuptools.

Distutils is now deprecated (see PEP 632) and all tagged issues are being closed. From now until removal, only release blocking issues will be considered for distutils.

If this issue does not relate to distutils, please remove the component and reopen it. If you believe it still requires a fix, most likely the issue should be re-reported at https://github.com/pypa/setuptools
