I think you can only do a blank by putting one very specific character. It can't be done on a phone as far as I know. I've tried various but they all either appear as is or is recognized as a "space" character and doesn't let me post.
My blank post is indeed an alt code, but it's not the one you're thinking of. As far as I know, it doesn't appear in any official list online because it's useless. It has four digits. It looks like something you can find on your keyboard but it actually isn't. It's literally the same, pixel for pixel.
AND HERE HE COMES IT'S......

THE DASH

yep that's what it looks like. Except the alt code for it is [alt]+0173 which for some reason creates an invisible dash.
"Hey guys do you think this zipper will break?"
"Nah, we will just strap it to the top of the car"
"Hey......um....Bro was that your shirt that just flew off?"
