| Hi Ryan, I’ve created attached unit, which takes a code point and returns the utf8 char as a string. It’s based on the Wikipedia article on UTF8 UTF-8 encodes code points in one to four bytes, depending on the value of the code point. The x characters are replaced by the bits of the code point: |

Description: Binary data
Hope it’s useful for you. If you improve the code pls let me know.

First thing I did was choose the unicode scalar U+1F496 (💖). Next I cheated and ask ChatGPT. :) Amazingly from my question it was able to tell me the scaler is comprised of these 4 bytes: 240 159 146 150 I was able to correctly concatenate these characters and writeln printed the correct character. var s: String; begin s := char(240)+char(159)+char(146)+char(150); writeln(s); end. The question is, how was 1F496 decomposed into 4 bytes?
