Raku seems to be more correct (DWIM) in this regard than all the examples given in the post... my \emoji = "\c[FACE PALM]\c[EMOJI MODIFIER FITZPATRICK TYPE-3]\c[ZERO WIDTH JOINER]\c[MALE SIGN]\c[VARIATION SELECTOR-16]"; #one character say emoji.chars; # 1 #Five code points say emoji.codes; # 5 #If I want to know how many bytes that takes up in various encodings... say emoji.encode('UTF8').bytes; # 17 bytes say emoji.encode('UTF16').bytes; # 14 bytes Edit: Updated to use the names of each code point since HN cannot display the emoji

You can represent it as a sequence of escapes. If Raku handles this the same way as Perl5, it should be: $a = "\N{FACE PALM}\N{EMOJI MODIFIER FITZPATRICK TYPE-3}\N{ZERO WIDTH JOINER}\N{MALE SIGN}\N{VARIATION SELECTOR-16}";

And if you try to say emoji.length, you'll get an error: No such method 'length' for invocant of type 'Str'. Did you mean any of these: 'codes', 'chars'? Because as the article points out, the "length" of a string is an ambiguous concept these days.
