I'm interested in parsing unicode scalars (I think they're called) to byte
sized values but I'm not sure where to start. First thing I did was choose the
unicode scalar U+1F496 (💖).
There's no such thing as "unicode scalar" in Unicode terminology:
https://unicode.org/glossary/
So, what do you mean? A Unicode code point? An Extended Grapheme
Cluster? Or something else? There are also several ways to encode
Unicode into a byte sequence - UTF-8, UTF-16LE, UTF-16BE, UTF-32, etc.
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?
I guess you should ask ChatGPT, who gave you the answer ;-)
