How do I do this

How do I do the thing that yall niggas be doing where you evade the character limit without actually meeting it? I see @hope do it a lot but Ive also witness non staff do it as well.

Sorry for the grammar I'm on mobile and its late so I don't really give a fuck

EDIT: this is not to break the rules I'm just curious

There's an Invisible character you copy/paste.

Staff are allowed too and when normal members do it it's a warning.
