In a previous tip you have seen that the PowerShell console supports all characters available in a TrueType font. You just need to convert the character code to the type "Char".
Here is a more advanced example that uses splatting to insert a green checkmark into your console output:
$greenCheck = @{ Object = [Char]8730 ForegroundColor = 'Green' NoNewLine = $true } Write-Host "Status check... " -NoNewline Start-Sleep -Seconds 1 Write-Host @greenCheck Write-Host " (Done)"
So whenever you need a green checkmark, use this line:
Write-Host @greenCheck
If the checkmark does not appear, make sure your console font is set to a TrueType font like "Consolas". You can set the console font by clicking the icon in the top left corner of the console title bar, then choose "Properties".
