I suspect this problem is related to the emojis on https://github.com/rochacbruno/dynaconf/blob/master/dynaconf/cli.py#L283

We need to find a way to safely output the emojis on windows, make it optional or remove it completelly.

I'm trying to reproduce this, and will go study to correct.

This issue seems to have been fixed in latest Windows updates. microsoft/terminal#190

I'm researching if this fix is only in Newer Builds. (I'm using Windows 11), and seeing how we can work around to not break the execution in older builds.

@ebenh What your windows version for me reproduce this in Virtual Machine?

[ebenh]

@ebenh What your windows version for me reproduce this in Virtual Machine?

Windows 7 x64

[endersonmenezes]

@ebenh you are using python 37, 38 or 39?
I will testing with 3.7 :)

Edit: I managed to reproduce the error with Python379 on Windows 7 Ultimate x64, I will try to bypass it.

[endersonmenezes]

@ebenh to bypass this error i found this solution:

You can use:

set PYTHONIOENCODING=utf-8

or

export PYTHONIOENCODING=utf-8

@rochacbruno We can add this env directly into Dynaconf or put a manual for use on Windows systems with older builds, I think this can also happen on Windows 8 and Windows 8.1.
What do you prefer?

[rochacbruno]

@endersonmenezes does it work if we put os.environ["PYTHONIOENCODING"] = "utf-8" on the top of the CLI file? of not then we can just add a note on the docs about this problem.

Or as a second option, remove all the emojis from the CLI output?

What do you think?

Probably getting rid of emojis is safer option pypa/pipenv#3131

[endersonmenezes]

I think we can keep the emojis and use PYTHONIOENCODING, as our String is passed by IO, just when it's not able to decode it will remove it, so we have the two solutions:

• Emojis removed where they don't work.
• Emojis working for those who like to put emojis on everything (like me) 😄

I think os.environ["PYTHONIOENCODING"] = "utf-8" the change will not change anything for newer devices that already have this by default, and helps users more, makes a learning curve for using dynaconf shorter, i can make a PR?

EDIT: The result would be similar to this change, simpler. https://github.com/pypa/pipenv/pull/3132/files
