Hrmm... that's odd. Could it be the font you're using is not unicode but ISO-somethingortheother. (And windows has some even funkier character sets.) You can display the mapping tables like this:

#!/usr/bin/perl -w
use strict;
use HTML::Entities qw(%char2entity %entity2char);
foreach (keys %char2entity)
{
  print "$_ = $char2entity{$_}\n";
}
foreach (keys %entity2char)
{
  print "$_ = $entity2char{$_}\n";
}

On my Linux box everything seems to have the right values.

Update: s/HTML:Entities/HTML::Entities/;
