I recently shipped the latest update to my SDU Tools collection.
This time I decided to add a tool that's in the "cute" category. It's called InvertString and you can see it action in the image above.
Yes, it takes an input string and returns a string that looks quite like an upside down version of the same string.
As part of the inversion I also reversed the order of the string so when you look at it upside down, it still looks correct. But if what you really want is a mirror image, you could combine it with REVERSE to achieve that outcome:
It's based on my implementation of USD Encoding that you can find described here:
It supports the English alphabet (sorry other cultures) and a variety of punctuation characters. It can take varchar or nvarchar input but returns nvarchar output so that we have a suitable set of characters to work with.
You can see the tool in action here:
