Hi

I dont understand the problem, why are you looking at the utf flag?

It appears to be something to do with use utf8;

No UTF8 flag for \xE9, not before nor after 

#!/usr/bin/perl --
use strict;
use warnings;
use Data::Dump qw/ dd /;
use Devel::Peek qw/ Dump /;
my %f = ( qq{cl\xE9}, qq{cl\xE9} );
Dump($_)for keys%f;
$f{qq{cl\xE9}}=qq{cl\xE9};
$f{qq{\x{2665} \N{U+1F42A}}}=qq{\x{2665} \N{U+1F42A}};
dd\%f;
dd(keys %f);
Dump($_)for keys%f;
__END__
SV = PV(0x3f7a8c) at 0x3f9b74
  REFCNT = 2
  FLAGS = (POK,FAKE,READONLY,pPOK)
  PV = 0x9a8ad0 "cl\351"
  CUR = 3
  LEN = 0
{ "cl\xE9" => "cl\xE9", "\x{2665} \x{1F42A}" => "\x{2665} \x{1F42A}" }
("\x{2665} \x{1F42A}", "cl\xE9")
SV = PV(0xb98cc4) at 0x3f9b84
  REFCNT = 2
  FLAGS = (POK,FAKE,READONLY,pPOK,UTF8)
  PV = 0xa78390 "\342\231\245 \360\237\220\252" [UTF8 "\x{2665} \x{1f4
+2a}"]
  CUR = 8
  LEN = 0
SV = PV(0x3f7ac4) at 0x99b9c4
  REFCNT = 2
  FLAGS = (POK,FAKE,READONLY,pPOK)
  PV = 0x9a8ad0 "cl\351"
  CUR = 3
  LEN = 0

But utf8.pm doesn't like it

$ perl -le "use Data::Dump; use utf8; dd qq{é}"
Malformed UTF-8 character (1 byte, need 3, after start byte 0xe9) at -
+e line 1.
"\0"


$ perl -le "use Data::Dump; dd qq{é}"
"\xE9"
