It looks like "Wide character in print" is an unrelated warning.

The real error is in Text::Wrap where we find this obscure piece of
code:

        if ($t =~ /\G([^\n]{0,$ll})($break|\n+|\z)/xmgc) {
                $r .= $unexpand 
                        ? unexpand($nl . $lead . $1)
                        : $nl . $lead . $1;
                $remainder = $2;
        } elsif ($huge eq 'wrap' && $t =~ /\G([^\n]{$ll})/gc) {
                $r .= $unexpand 
                        ? unexpand($nl . $lead . $1)
                        : $nl . $lead . $1;
                $remainder = defined($separator2) ? $separator2 : $separator;
        } elsif ($huge eq 'overflow' && $t =~ /\G([^\n]*?)($break|\n+|\z)/xmgc) {
                $r .= $unexpand 
                        ? unexpand($nl . $lead . $1)
                        : $nl . $lead . $1;
                $remainder = $2;
        } elsif ($huge eq 'die') {
                die "couldn't wrap '$t'";
        } elsif ($columns < 2) {
                warnings::warnif "Increasing \$Text::Wrap::columns from $columns to 2";
                $columns = 2;
                return ($ip, $xp, @t);
        } else {
                die "This shouldn't happen";       <<<--- here
        }

The command we are running is:

$ ./podwrapper.pl --section 1 --man guestfs-release-notes.1 --text guestfs-release-notes.txt --html html/guestfs-release-notes.1.html --license GPLv2+ guestfs-release-notes.pod 
podwrapper.pl: wrote guestfs-release-notes.1
podwrapper.pl: wrote html/guestfs-release-notes.1.html
podwrapper.pl: wrote guestfs-release-notes.txt

which as you can see works fine for me.

I am guessing you are using Archlinux for this?  Does the
podwrapper.pl command on its own work?

It may be something to do with a too-long line in the file ...

Rich.
