You can use Unicode characters like and as you use any other character like 'a' or 'b' as long as the underlying font includes them.

A small example that you can build from is the following. Printing names of the content of the current directory with with a different symbol depending whether it is a file or a folder.

PS> Get-ChildItem | 
      Format-Table @{N='Name'
                     E={if ($_ -is [System.IO.DirectoryInfo]) {
                          " $($_.Name)"
                        } else {
                          " $($_.Name)"
                        }}}
