I came across this post that accidentally contains a train emoji. Copy/pasting into a new post worked, even though I thought emoji were scrubbed from submitted text. And indeed when I select a train emoji on my phone keyboard... no trains!
I can't figure out what makes the train in that post special, does anyone know what's going on here? User Zokier mentions "private area unicode" but I'm having a hard time grokking how that causes this issue.
