Crash during unitest

[mtribiere]

I use this library in a project, and use the CMake/Ninja combo to unittest it.
On Linux no issues, but on Windows I have a crash. Probalby some issues with the Powershell encoding.
Thanks for your help.

That's unfortunate, I know. But sadly, I don't know what to do to circumvent these weird windows incompatibilities...
I'd say perhaps you could try WSL2. Since it is a linux environment it should work flawlessly.
If everything else fails, I think you'd have to use both the classic bar and spinner, since they only use ASCII characters.

Thanks @ThomasByr, but I think the unicode "breaks" tool has nothing to do with it since it is not used on the alive_bar impl at all.
