Hello, this is the short guide how to make the same name for every character. (not an infinite amount tho)

Here you can copy/paste the invisible character for your nickname: https://www.invisibletextcharacter.com

How it works:

There is graph with invisible characters below, you can copy the smallest ones (or literally the ones that have zero space) and paste them in every place of nickname.

For Example: my nickname is Archnemesis, you can paste the invisible character with no space before A, or after S, or between these letters (if you want to paste between letters, use zero space ones).

Good luck and enjoy your nickname.
