Motivation
On the system Powershell GUI in Windows, unicode isn't supported. The same is going to be true for other terminal applications.

I saw that pre-commit-update has a way of handling this with fallbacks;:

We could use a similar approach.

Summary of desired enhancement
Provide a way to fall-back on universal characters on terminals that don't support unicode.
