in thread Jargon relating to Perl strings

Right, we do mean something different with "the UTF-8 doesn't matter". I interpret that as the only difference between the internal representation of the strings is whether the UTF-8 flag is set or not -- but you use it to mean "it doesn't matter whether the internal encoding is UTF-8 or not".
use Devel::Peek; my $x = my $y = "\xC9ric"; utf8::upgrade($x); utf8::upgrade($y); utf8::encode($y); Dump($x); Dump($y); # Now $x and $y differ only in the setting of the UTF-8 flag say substr($x, 0, 1) eq substr($y, 0, 1) ? "equal" : "different"; __END__ SV = PV(0x8cd80cc) at 0x8cea9ec REFCNT = 1 FLAGS = (PADMY,POK,pPOK,UTF8) PV = 0x8cef6e8 "\303\211ric"\0 [UTF8 "\x{c9}ric"] CUR = 5 LEN = 9 SV = PV(0x8cd803c) at 0x8ceaa28 REFCNT = 1 FLAGS = (PADMY,POK,pPOK) PV = 0x8cf38b8 "\303\211ric"\0 CUR = 5 LEN = 9 different
