Thanks for the question! That was interesting.
So the special form-feed character is bugger in powershell. If you repeat this, you will simply get an odd character or square if you cannot display it. But if you copy and paste it back into the powershell terminal, just move the command entry point to the top of the screen. Odd
. powershell $oldWord -replace 'REGEX_GOES_HERE', 'THING_TO_REPLACE_WITH_HERE, :
$oldWord -replace '[\f]', '' #You can also use \r for carriage return, \n for new line, \t for tab, \s for ALL whitespace
Form-Feed.
