in thread How to set the UTF8 flag?

Oh okay. I don't understand what you mean by utf8 vs UTF-8. Is there a difference?

Also, I'm not sure why I got two thumbs down on my question. Is it not allowed to ask questions in here anymore? There must have been some rule changes since 2016 when I first got on this forum.

    utf8 is a Perl-specific extension of UTF-8 capable of encoding any 72-bit value (but it's limited to encoding values the size of UVs in practice).

    I didn't downvote, but it's probably because you completely fabricated a definition of the flag.

      The mystery deepens. You said 72-bit value? Why? There only 1,114,112 code points. That could be stored in 3 bytes. What kind of 72-bit values are you referring to?

        Actually, 4 bytes. See UTF-8.

        The values can mean anything you want. Strings characters aren't limited to Code Points. In fact, it's very common for strings to hold things other than Code Points.
