[Roguesharp & RLNet] How to "print" glyphs?

I wasn't sure how to word this.

I am new to this, I just started yesterday, I found REXPaint and am using it to design a ui for my game, but I can't figure out how to "print" the symbols/glyphs used in it's font, mainly the ones I want to use for some borders, "═", when I just put that into the print command it displays "P".

it's probably me just being stupid but any help would be appreciated.

EDIT: I figured it out thanks to HexDecimal!
