As for the question you added,

Explain why you think this……should produce different output than this…

I agree that there should be a function that does that, but it's not reverse.

Explain why you think

my $water_samples = join '', map chr, 113, 101, 769; my $last_sample = substr($water_samples, -1, 1); print(ord($last_sample), "\n");

should produce different output than

my $water_samples = join '', map chr, 113, 101, 769; $water_samples = reverse($water_samples); my $last_sample = substr($water_samples, 0, 1); print(ord($last_sample), "\n");

Update: Corrected my numbers.

    Your rhetorical volley is irrelevant and off-topic as it has nothing whatever to do with Unicode.

    My simple, clear, plain point is that the Perl reverse function is broken because when it reverses what is simply, clearly, plainly a Unicode string with grapheme clusters or jamo in it, it gets it wrong.

    Perl's built-in string reverse function is not fully Unicode-conformant. That's all.

      I don't understand your point. Of course it doesn't handle Unicode. We've always been in agreement about that. The conversation started when you claimed it should and that it shouldn't handle code you just called "rhetorical" and "irrelevant".

      Update: Cleaned up the wording.
