Invisible Char

So idk how to do this can someone post invisible chars here that don't take up space. Like on the site tha can't be named it won't make my online person symbol go really far away. So basically invisible characters that aren't obvious/take up as much space as a normal char if that makes sence

To do this, open up the start menu.
Then search for "character map"
Open up character map
Then scroll through until you find a black space
Select it
Copy
Paste
