thing i made to talk in secret if you send this to someone and want to specify it's in five-bet, format it like this: FB<character set (use S for standard, R for reduced, ? for unspecified character set, paste character set for otherwise)> [encoded message goes here] standard character set: abcdefghijklmnopqrstuvwxyz,.!?():;-'"~`@#$%^&*_+[]{}\|<>1234567890 reduced character set: abcdefghijklmnopqrstuvwxyz
to make a custom character set: - rule 1: total number of possible characters must be 1 more than a multiple of 5 (or, in other words, 5n + 1 when n is an integer) - rule 2: make sure each character only appears once in the character set
