Determine if a string has all unique characters: Difference between revisions

Raku works with unicode natively and handles combining characters and multi-byte emoji correctly. In the last string, notice the the length is correctly shown as 11 characters and that the delta with a combining circumflex in position 6 is not the same as the deltas without in positions 5 & 9.

 

my $i = 0;

print "\n{$str.raku} (length: {$str.chars}), has ";

if any(%m.values) > 1 {

say "duplicated characters:";
