in thread Byte counts and Seek function

That's the utf8 pragma. I know what it does in the posted code: nothing, because there are no non-ASCII characters appearing literally in the source code.

What's the utf8 function in the OP's code do?

    Oops. Visually scanned for it, but didn't see the utf8 function call the first time through. Should have used a highlighting finder!   (Damned human eyes...)

      utf8::xxx functions can be used without "use utf8". it's documented.

        Interestingly, the utf8::utf8() function is not documented (Strawberry 5.14.4.1, online 5.18.0), although it exists. What does it do?

        Update: Sorry, I was confused by Perl's autovivification behavior.

        >perl -wMstrict -le "print exists &utf8::is_utf8 ? 'yes' : 'no'; print \&utf8::is_utf8; ;; print exists &utf8::utf8 ? 'yes' : 'no'; print \&utf8::utf8; " yes CODE(0x68c66c) no CODE(0x68c17c)
