The 5.10 documentation for "pack" says the "c" and "C" are "eight bit" and "octet" but they no longer (always) are.

So it works for values there have more than eight bits too. I'm not convinced that's a problem. It could die or warn, but it's more useful if it doesn't.

At least it works for all eight-bit values. It didn't before 5.10. 

use strict;
use warnings;

use Test::More tests => 4;

my $ch = chr(0xA0);

utf8::downgrade( my $dn_ch = $ch );
utf8::upgrade(   my $up_ch = $ch );

is(unpack('c', $dn_ch), 0xA0-0x100, 'c, internal format 0');
is(unpack('c', $up_ch), 0xA0-0x100, 'c, internal format 1');
is(unpack('C', $dn_ch), 0xA0,       'C, internal format 0');
is(unpack('C', $up_ch), 0xA0,       'C, internal format 1');
