Hi ikegami,

your information was a hint in the right direction. Thank you for that.

But now I face a different error. I made a litte program to show the problem:

#!/usr/bin/perl
use strict;
use warnings;
use PerlIO::encoding;
use Encode;
use Data::Dumper;

my $a = "\xe2\x82\xac"; #Euro Sign in UTF-8
my $euro_in_unicode = decode("UTF-8", $a);
print Dumper(\$euro_in_unicode), "\n";

open my $fh, ">", "output.txt" or die $!;
{
   local $PerlIO::encoding::fallback = Encode::FB_DEFAULT;
   binmode $fh, ":encoding(latin1)";
}
print $fh $euro_in_unicode, "\n";
close $fh;

The output of Dumper shows the right codepoint $VAR1 = \"\x{20ac}";. The file output.txt does have a ? sign in it as the Euro-Sign can't be displayed in REAL latin-1, but I get the additional output

Close with partial character at am85.pl line 18.

Can someone explain that? What do I have to do to get rid of that? What is wrong?

Best regards
Andreas

I've encountered some problems too, as I mentioned. It appears to be a flaky or poorly documented interface. I don't have the time to hunt down the problem, but you could file a bug report and encode manually for now.

open my $fh, ">", "output.txt" or die $!;
print $fh encode('latin-1', $euro_in_unicode), "\n";
close $fh;

Update: Taking a hint from the source, the following seems to work. No idea what STOP_AT_PARTIAL means.

#!/usr/bin/perl
use strict;
use warnings;
use PerlIO::encoding;
use Encode;

my $euro_in_unicode = chr(0x20AC);

open my $fh, ">", "output.txt" or die $!;
{
   local $PerlIO::encoding::fallback =
      Encode::FB_DEFAULT|Encode::STOP_AT_PARTIAL;
   binmode $fh, ":encoding(latin1)";
}
print $fh "$euro_in_unicode\n";
close $fh;
