Description:

There are plenty of functions out there to find and manipulate unique or duplicate values within a given list of ΒΆ delimited values, but I couldn't find anything that looked for duplicate *characters* within a string. I whipped this one up.

It's simple enough but I figured I'll upload it for the next person who goes looking for it. It took me more time to look for it than to recreate it because I assumed there *must* be one out there! There probably is one and I just didn't use the right search terms.
