Get unicode by hex string in Ruby [duplicate]

Question

Given a hex code, for example: 1f60d, how do I find the corresponding unicode (code point) 😍?

Answer 1

You could do that by using Array#pack:

["1F60d".to_i(16)].pack("U*")

Answer 2

Convert the string to an integer (e.g. via hex) and the integer to a character via chr:

'1f60d'.hex.chr('UTF-8')
#=> "😍"
