Fancy Key is a great app! You use it to get unicode texts,I use it all the time, here are some reasons why you should get Fancy Key:
1: It has loads of shapes to use in your projects
2: (Not fully hopscotch related) You can customize you own keyboard
3: It is really useful in making emojitecture
4: There is pre made emoji pixel art
5: You can add GIFs
I use Fancy Key in almost all of my projects!
It is free!
NOTE: I am not trying to make you get it.
A Happy Coder OOOOOOOUUUUUUUUTTTTTTTTT!
