UnicodeEncodeError: 'charmap' codec can't encode character '\u23f0' in position 328: character maps to <undefined>_

[devkeydet]

I have a very simple test here:
https://github.com/devkeydet/actions-includes-test/blob/main/.github/workflows-src/convertme.yml

I installed actions-includes using pip. I run the following command:

python -m actions_includes ./.github/workflows-src/convertme.yml ./.github/workflows/converted.yml

I get the following error:
_Expanding ./.github/workflows-src/convertme.yml into ./.github/workflows/converted.yml
