Installation fails on Windows, possibly due to UTF-8 encoding issues

[clone45]

Hello! Thanks for creating this!

Following your installations instruction verbatim from your video (https://www.youtube.com/watch?v=qXxO7SvbGs8) on Windows 11 resulted in the following error when running:

pip install .

The error was:

C:\Code\agency-swarm>pip install .
Processing c:\code\agency-swarm
  Installing build dependencies ... done
  Getting requirements to build wheel ... error
  error: subprocess-exited-with-error

I found a work-around, which is to run the following before that instruction:

set PYTHONUTF8=1

I don't know if this is something that can be fixed, but if so, that might save other Windows users some pain. :-)

Even setting pythonutf8=1 didn't work for me either. Figured it out, looks like the setup.py just needs to force the encoding for the readme: long_description=open('README.md', encoding='utf-8').read(),
