Rot 13 is a cipher. It's a substitution cipher, and more specifically a shift cypher or Caesar cipher. It's not a secure cipher but it is one. Base64 is an encoding. It's an algorithm, no attempt at secrecy, thus not a cipher.
And thus we arrive at SCREAM64 encoding, base64 in scream cipher.
I did something similar a while back but using all the invisible characters to encode extra data into telegram messages for metadata storage https://github.com/sixhobbits/unisteg
There are a little over 256 unicode Combining Marks that have a 2-byte UTF-8 encoding. I picked a set of them, defining an encoding I call zalgo256: https://gist.github.com/DavidBuchanan314/07da147445a90f7a049... Since an arbitrarily tall stack of combining characters still counts as one grapheme cluster, if some application limits string length by counting grapheme clusters then you can stuff an unlimited amount of…
A demonstration as a comment on the gist would probably work! I'd love to see that
Now pack even more info in each character with Zalgo text.
am I unusual in not really seeing the "creepiness" of zalgo text?

Good point, added

And what do you think is the algorithm from the article? Looks awfully similar to base64 to me, except its lacking the bit-shifts. Both use a lookup table like that.
You'd do better debating this with a real life friend over a pint, rather than wasting your time trying to argue with multiple people here.
