name change help

[Trick]

How do u change ur username to a single letter? I'm getting close to 5 koins and I wanted to know so I don't mess anything up.

 

[Trick]

You put the single letter then you put 2 invisible characters after.

Alt+255 is the alt code for the invisible characters.

Or copy and paste this -->  <--

Would it work on mobile my computer is broken.

If you're able to copy this ->  <- then I believe It'll work.

So just this. P-> <-? It seems like it's right.
