Hello Dave

it seems 0x80-0xFF characters with chr() still have to be upgraded even if utf8::all. Below code shows character with chr() in 0x80-0xFF range doesn't have UTF-8 flag.

use strict; use warnings; my $str='\334ber@n\374ber.com'; $str =~ s/\\([0-7]+)/pack('U', oct('0'.$1))/eg; binmode STDOUT, ":encoding(UTF-8)"; print "$str\n"; print utf8::is_utf8($str) ? "str is ...utf8\n" : "str is ...not utf8\n +"; use 5.010; use utf8::all; my $string='\334ber@n\374ber.com'; $string =~ s/\\([0-7]+)/chr oct $1/eg; print "$string\n"; print utf8::is_utf8($string) ? "string is ...utf8\n" : "string is ...n +ot utf8\n"; my $string='\334ber@n\374ber.com'; $string =~ s/\\([0-7]+)/chr oct $1/eg; utf8::upgrade($string); print "$string\n"; print utf8::is_utf8($string) ? "string is ...utf8\n" : "string is ...n +ot utf8\n";
I think utf8::all is utf8::almost.
