[Python] Test printing unicode characters

[dbrattli]

• Print unicode character to make sure printing does not blow up
• Code cleanup and formatting

Well one thing I just noticed is there doesn't seem to be any python tests actually running on the windows runs

[MangelMaxime]

If they don't run there are no errors, so it means that it works 😏

More seriously, I have PR testing a fix for the Python tests on windows here #3569

Waiting for it to run and will merge it if all is fine.

[MangelMaxime]

I rebased this PR to the latest version of main which as the CI fix in it.

While it doesn't show the character it doesn't seem to blow up. Puzzling.

I think it could be interesting to check if this is also the case when running it on a local Windows machine with different terminals like Cmd, Windows Terminal, Git bash, etc.

Just to check if this is not just a problem of encoding based on the terminal used by the CI

@dbrattli Which formatter are you using for Python code?

This is so I can install it on my machine too when contributing to the python code.

[dbrattli]

@MangelMaxime I'm using ruff format, https://github.com/astral-sh/ruff#usage. I've btw added it so it formats the files in the generated fable-library in temp.

[MangelMaxime]

Ok thank you @dbrattli.

I think one of the next thing I want to add to the repo is auto format of the different source code when possible, just so we all write the same things. And it will also clean up some of the files who use odd formatting rules

@MangelMaxime I'll open an issue on this topic so we can discuss more
