Patrick Gruenauer notes that Powershell can display Unicode characters and emoji:

For showing all (or almost all) characters run the following code. The example gets 15.000 characters.

# Showing Unicode 16-bit character
for($i=0; $i-lt15000;$i++) {
   "Char $i : $([char]$i)"
}

Jeff Hicks wants to stop a shoulder-surfing attack:

If I print this or send it to a file, I might not want the computername to be shown. Or maybe even my name. I want PowerShell to handle this for me. In short, I need to replace strings like ‘Prospero’ and ‘Jeff Hicks’ with some like XXX and ‘Joe Doe’.

PowerShell has a Replace operator. Or I can use regular expressions. Naturally, I wenbt with the latter.

Read on to see what you’d need to do.

Robert Cain dives a bit further into objects in Powershell:

So far we’ve covered a lot in this series on PowerShell Objects. We began by creating a class using the class keyword introduced in PowerShell 5. We then looked at using PSCustomObject to create new objects, then add methods to those objects. In the previous post, we used C# code to create our PowerShell objects.

In this installment, we’ll see how to add properties and methods to existing objects created by someone else. For this example we’ll use objects returned by the Get-ChildItem cmdlet, but we could use any objects.
