I figured it out, its three bugs here on win32

#!/usr/bin/perl --
use utf8;
binmode STDOUT, ':encoding(UTF-8)';
binmode $DB::OUT, ':encoding(UTF-8)' if $DB::OUT;
our $junk = "\x{5ff}\x{5ff} \x{25c4} \x{2663} \x{2665} \x{2663} \x{25b
+a} \x{5ff}\x{5ff}";
$junk .= "$junk\n";
print $junk;
[download]

$junk .= "׿׿ ◄ ♣ ♥ ♣ ► ׿׿\n";

the padre output pane, doesn't show any output when you run (or debug) the file you're editing

If you binmode STDOUT, that still leaves $DB::OUT to get binmoded (bug in debugger)

The "Debug Output" pane is not unicode aware, or the filehandle its reading from hasn't been binmoded to decode utf8, so what gets displayed correctly in the editor pane (the heart, clovers, and triangles above) doesn't in the "Debug Output" pane

Oh, and when pasting/posting to perlmonks with firefox, firefox flips the triangles around, they were originally like this

$junk .= "׿׿ ► ♣ ♥ ♣ ◄ ׿׿\n";
