I filled it with "I like bananas" annd selected "no emojis" and "Happy" and the result was:

> "Hello! I'm a proud banana enthusiast sharing my love for this tropical fruit on Facebook. No emojis, just pure banana goodness. Don't forget to follow for more banana fun! #BananaLove #FruitFanatic #HealthyLiving [banana emoji] [banana emoji]"

where [banana emoji] was the actual banana emoji, but HN removes them.

In another try, I got emojis again, and the word "Happy" was leaked to the result.

Yeah, this needs to be fine tuned. I will look into it asap
