As best as I can tell, a code point is a index into a character set. I don't see how that relates [unless you're saying something is a code point if it's internally encoded using one encoding (UTF-8), but somehow it's not if it's internally encoded using another (iso-latin-1)]. All I have is a packed byte with no association to any character set.

unpack 'C', substr("\xA0$s", 0, 1) doesn't give 0xA0 in 5.8.8, and that's a bug.

have always been about how the bytes are encoded into memory

Of course. You're saying it also matters how those encoded bytes are encoded, and I disagree with that.

unpack "H*", pack "U", 0x1234 results under 5.10 are mostly nonsensical, not "fixed".

I forgot to address this earlier.

I can see a case for unpack 'H*', $characters_higher_than_255 returning something more sensible. Same idea as allowing characters above 255 for 'C': It doesn't hurt anything. It even aids backwards compatibility.
