Section tool.poetry.authors does not accept umlauts (ä, ö, ü)

[se-jaeger]

• 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 version and name: macOS 11.4
• Poetry version: 1.1.7

Issue

I'm using the following section:

[tool.poetry]
...
authors = ["Sebastian Jäger <message@sebastian-jaeger.me>"]

and ran: poetry build
This failed with the message: (...) Invalid author string. Must be in the format: John Smith <john@example.com> (...)

Replacing ä with ae works as expected.

In my opinion the error should be more descriptive, e.g.: (...) Invalid author string. Must be in the format: John Smith <john@example.com> and should not contain special characters(/ umlauts) (...)

Full Stack Trace

-> poetry build -vvv

Hello @se-jaeger,

unfortunately I'm not able to reproduce your problem.

So let's try with the default questions :)

• How did you install poetry?
• How was the pyproject.toml created?
• Which text editor are using if you manipulate the file by hand?
• Which shell are you using?

Hey @finswimmer,

thanks for your quick answer!

Regarding your questions:

• installed using brew: brew install poetry
• poetry new project-name
• I'm using VSCodium
• and zsh

[finswimmer]

Could you upload your pyproject.toml somewhere? I suspect an encoding problem of the file, which would make it hard/impossible to debug if you just paste the content here.

[se-jaeger]

It is directly after creating the project:

[tool.poetry]
name = "project-name"
version = "0.1.0"
description = ""
authors = ["Sebastian Jäger <message@sebastian-jaeger.me>"]

[tool.poetry.dependencies]
python = "^3.9"

[tool.poetry.dev-dependencies]
pytest = "^5.2"

[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"

But you're right, removing the ä with VSCode solves it.

[finswimmer]

Maybe related? #798

[se-jaeger]

Confirmed! It's the ~/.gitconfig file with broken encoding. Poetry then copies this over without checking it.

[srinivasreddy]

This can be closed?

[se-jaeger]

Sure. Thought someone wants to investigate this further or even fix it.
Thanks a lot!
