Is there an easier replacement for <<number::utf8>>?

Questions / Help
1

I have a didactic example that I’ve used to teach several languages, and it requires getting an Unicode character from a integer, accomplished in Python as char(n).

I know I can do it with <<n::utf8>> but that opens a huge syntactic can of worms. Is there a simpler option?

Thanks!

List.to_string([n]).

iex(5)> List.to_string([243])
"ó"

iex(3)> <<243::utf8>>
"ó"

Thanks, @LostKobrakai and @alco!

iex(1)> List.to_string([0x1F44D, 0x1F64F])
"👍🙏"

For context, this is the didactic example I was updating: rf/elixir at master · ramalho/rf · GitHub

Thank you!
