If it is only backspaces you want to remove, try this:
my $text = "abcDE\x08\x08xyz\x08Z"; # \x08 is the backspace character while ($text =~ m/\x08/g) { substr($text, pos($text)-2, 2, ''); } print $text, "\n"; # emits: abcxyZ
Actually, I'm a little surprised that this works. I would think that modifying $text before the last match position in a m//g loop would screw things up.

Update: A slightly more optimized version:

while ($text =~ m/(\x08+)/g) { substr($text, $pos-2*length($1), 2*length($1), ''); } print $text, "\n";
