Although I'm not really sure why, the following code change seems to work:
#!/usr/bin/perl
use strict;
use warnings;
use utf8;
use Encode;
use Data::Dumper;
#$Data::Dumper::Useqq = 1;
binmode STDOUT, 'utf8';
our $VAR1;
my $data = 'ä'; # this is a non-ACII a Umlaut
my $dump = Dumper( encode( 'utf8', $data ) );
print $dump, "\n";
eval $dump;
print $dump, "\n";
if ( $data eq $VAR1 ) {
print " == equal\n";
}
else {
print " != not equal\n";
}
#print Dumper( $VAR1 ), "\n";
print "Data: $data\nVAR1: $VAR1\n";
print "original is utf8 = '" . utf8::is_utf8( $data ) . "'\n";
print "restored is utf8 = '" . utf8::is_utf8( $VAR1 ) . "'\n";
It's Dumper that generates the problems, not the eval:
$VAR1 = "\x{e4}";
has no way to determine that there's something utf8-related in the string.
Update: There's some additional info available
here.
Update2: Looks like the proper solution is actually to just set
$Data::Dumper::Useperl = 1;
According to the doc, you just have to use a Perl newer than 5.8.0 to have this working - it does work for me, Perl 5.10.0.
