Is there any website or list of characters that we can use in our usernames?

I was trying to find an invisible character to change my username back but was unable to do so but also I realized certain symbols are allowed while others aren't so I'm wondering which are allowed maybe there's certain kinds that are?

Any help would be appreciated

There used to be a program that was floating around that would generate usernames for you with correct CHARS though I don't know what happened to it.

I forget the ascii char, but I believe it should be found here: http://www.ascii-code.com/

I recall it being called a non-printing space. I believe this it what you're looking for, however if I remember correctly Omni was supposed to add a filter to remove that character from being put into usernames here.
