[Question][Hw6] Is there a way to handle unicode without external library?

Hello. I'm trying to generate a character from unicode codepoint as described in the json specification:

But from my search in ocaml you have to use an external library like uutf to do this, is there a way to do without an external library?

oops, sorry for notification, just "\u{codepoint}" works...

First code point	Last code point	Byte 1	Byte 2	Byte 3	Byte 4
U+0000	U+007F	0xxxxxxx
U+0080	U+07FF	110xxxxx	10xxxxxx
U+0800	U+FFFF	1110xxxx	10xxxxxx	10xxxxxx
U+10000	U+10FFFF	11110xxx	10xxxxxx	10xxxxxx	10xxxxxx

character
    '0020' . '10FFFF' - '"' - '\'
    '\' escape

You can implement a function that converts a code point into a stream of bytes, and call Bytes.to_string.
