How to show the pin symbol in PowerShell Julia?

I use Julia on Windows and when I open the REPL ti says that it’s been run in PowerShell.

Once I pin a package, I expect the pin symbol to appear next to the package, but on my machine it’s a rectangle containing a question mark, see

Does anyone know to fix it? Is there some font settings I need to enable?

See https://github.com/JuliaLang/julia/blob/v1.4.1/doc/build/windows.md#unicode-font-support . I think the answer is to use a better terminal. The docs suggest Conemu or Mintty.

I use Windows Terminal and I am pretty happy with it. https://github.com/microsoft/terminal (link to the Microsoft Store https://www.microsoft.com/en-us/p/windows-terminal-preview/9n0dx20hk701).
Caveat is that this requires Windows 10 v1903 or later.
