UnicodeDecodeError when running poetry install on Windows 11

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS and version: Windows 11 (latest)
• Poetry version: 1.1.14

[dimbleby]

per the stack trace, it's obviously trying to read your README.

      55│             with package.readme.open(encoding="utf-8") as f:
    → 56│                 meta.description = f.read()

Is there something unusual in that? Is it not utf-8?

[brno32]

Wow lol. This was a default README generated by GitHub, so not sure how something non utf-8 got in there, but removing it did the trick. Thanks
