If I ✍️ a 📄 using emojis instead of words, does that affect the validity of the 📄?
Mary will only use the 🔑 to open the front 🚪 of John's 🏡 in order to feed his 🐈. Mary will feed the 🐈 three times every day for one 🗓️. John will pay Mary 💯💲.
What if an emoji is ambiguous? A contract to sell a 🔫 could involve a firearm or a water gun, depending on fonts.
Of course, this isn't a good idea.
