to use this, just type valid hexadecimal for example: 68 65 6c 6c 6f (it translates to 104 101 108 108 111 / hello :D) and it'll translate to decimal (if you want, you can use the output to convert it to unicode) ↓ if you want to save the output, save the "output" list as a txt file or copy the variable to your clipboard, then you can put it into a decimal to unicode translator (for more info, go to notes and credits)
if you put too many characters without a space separating them, your decimal output can go past 1.79 x 10 ^ 308, causing it to output "infinity" to prevent this from happening, you would have to use BigInt, but i cant recreate that in scratch (even if i could, it would cause MAJOR lag with large numbers) so theres nothing you can do about the numbers turning into scientific notation
