Thanks a lot for this. And it seems that is indeed the solution. The scripts have been running for years without any issues, though. So I find it quite astonishing that this really is the case. oO I uploaded a test3.pl where I tried your suggestion and this one works without any issues. But urgh... That would mean I have to adjust that in dozens of scripts... My whole site is running on Perl... :(


Link: https://digioso.tk/test3.pl

Source code test3.pl 
#!/usr/bin/perl -w
use strict;
use CGI;
use CGI::Carp qw(fatalsToBrowser warningsToBrowser);
use lib "/home/digioso/web/digioso.tk/stuff";
use Navi2;

my $cgi = Navi2::create_cgi();
Navi2::print_navi($cgi);
print "test";
Navi2::end_navi($cgi);

Source code Navi2.pm: 
#!/usr/bin/perl -w

use strict;
use warnings;
use CGI;
use CGI::Carp qw(fatalsToBrowser warningsToBrowser);

package Navi2;

binmode STDOUT, ":utf8";

sub create_cgi
{
    return new CGI;
}

sub print_navi($)
{
    my $cgi = shift;
    print $cgi->header (-type => 'text/html', -charset => 'UTF-8');
}

sub end_navi($)
{
    my $cgi = shift;
    print $cgi->end_html;
