You're a madlad for doing this and I respect it all the way 🫡

@Moosems i have only added the templates so far and the base handler. I'd love to receive some help with the implementations though ❤️

I will certainly try, but theres no guarantee I'll be much help. I'd say the easiest character to start with is the Carriage Return, though we will likely have to keep track of the visible string and actual string separately:

x = "xy\r\rza"
print(x)
# Prints "za"
