Hi, I hit a temporary glitch, then this started working for me. I don't know what to tell you. I suspect you have file encoding mismatches somewhere. When I download your code example, the œ dosn't show up in my editor or Tk. I then manually copy&pasted in œ from your html into the Tk program and it ran. Maybe some unicode guru knows the reason? 
#!/usr/bin/perl
use warnings;
use strict;
use Tk;
use Tk::TextUndo;
use utf8;

my $main = MainWindow->new;

my $middle = $main->Frame(-borderwidth=>2,-relief=>'groove')->grid(-ro
+w=>0,-column=>1,-sticky=>'nsew');

my $middlebox = $middle->TextUndo (
                      -font => 'arial 20',
                           -wrap => 'word',
                           -spacing2 => 10,
                           -spacing3 => 30,
                           -takefocus => 1,
                           -background => 'white',
                           -width => 70,
                           -height => 10,

                           )->grid(-row=>0, -column=>0, -sticky=>'nsew
+');

$middlebox->insert('end',"This is a test of the œ character\n");

print ord('œ'),"\n"; # prints 339
print chr(339),"\n"; 

$middlebox->insert('end', ord('œ') );
$middlebox->insert('end',"\n");
$middlebox->insert('end', chr(339) );

MainLoop;
