Your comment made me really curious, could you please elaborate how this number system can be used in Steganography? I have a basic idea of steganography, but I want to know more

These glyphs are not immediately recognizable as numbers by most people. This can assist the purpose of hiding information visually.

It can also be used to avoid computer vision solutions from detecting numbers in an image, avoiding OCR, etc.

I think we can assume that parent made a typo, or suffered autocorrect , and most likely meant stenography

You assumed wrongly this time.

Well color me surprised
