Copy and paste produces an unknown character square (White Medium Square: 
) in notepad++. And actually trying to run it produces a strange error: startup line 12: invalid ${} variable substitution at letter 1 Also, I tried to punch it in directly and it gets displayed as a question mark.
Just as an FYI, when I did have it working (I’m sure I did, but I have no idea what happened, other than a few crashes, but I saved, well, IDK) (You know what. I updated Notepad++, I might have to try something in a moment), it was through:
*temp super_blank " " (dscourse hates that: Here the “Mongolian Vowel Sepataror”)
$${super_blank}{variable}
(If you copy/paste you should be able to see there’s a non-displaying space between the characters on the linked page).
