OK, sometimes I really find odd ways to occupy my time. So, I’m sitting at LAX for a two hour layover and I start working on improving the transcripts that I make while teaching PowerShell. I’m looking for a separator character for my prompt and discover something amazing. The ISE has something like 55,291 characters. Not all of them are displayable. I’ve found myself trying to get a special ASCII character to many times. Time to code it. The help files says it all. I added this to one of my modules so I always have it.
