Q: What is this? A: A way to store data in comments, can be used for save codes. Q: How can I use it in my game? A: Not yet, I'm working on it Q: How much data can it save? A: 7929 bits ≈ 991 bytes ≈ 0.99 kilobytes ≈ 0.97 kibibytes Q: Is this allowed by the scratch team? A: I think so. It doesn't use invisible characters. Q: Is there a more efficient way? A: You can store more data in forum posts, but comments have a limit of 500 characters and of all 65536 length-one characters this project uses 59396. The other characters are invisible, case sensitive, surrogates or control characters. You could include the 1173 case sensitive characters, but then the project would be slower and you had less than two extra bytes. Q: How does it convert characters and numbers? A: The project has a variable containing all possible characters. To convert a number to a character, it uses the letter of block. To convert a character to a number, the project uses binary search, because you can compare strings/characters in scratch/javascript like numbers. Q: How did you find all these characters? A: I used python. Useful website: https://unicodes.jessetane.com/
