Does anyone know how to do this?

How can you put something like this in your mission?

That's hella hard to do in my opinion. I tried it and I came up with something that looked like me in the morning x]

Hmm.. it's really hard to do and takes a great deal of patience editing your mission.

I think it uses the character that is just a space 'cause missions that use all 3 lines, the second line has to be longer than line 1 and 3
