I’m confused that this thread about cultural differences is more than 50 posts long, but the obvious cultural issue with this hasn’t mentioned yet. Although it has led to serious misunderstandings in the past.
Quoting Wikipedia: “Traditions differ as to whether popcorn is consumed as a hearty snack food with salt (predominating in the United States) or as a sweet snack food with caramelized sugar (predominating in Germany).”
That’s why I’m strongly opposed to this proposal: The question, whether the 
emoji means salty or sweet popcorn has the potential to deeply divide the community and to become the next landuse/landcover or phone/contact:phone moment in our project.
