All the pieces were there in the thread. I simply rearranged them... 
#!/usr/bin/perl -wT
use strict;

my $bin = ascii2bin('Rolf');
my $ascii = bin2ascii($bin);

print "bin   => $bin\n";
print "ascii => $ascii\n";

sub ascii2bin {
  my $ascii = shift;
  my $bin = join '',  map {sprintf "%08b", ord($_)} split //, $ascii;
  return $bin;
}

sub bin2ascii {
  my $bin = shift;
  my $ascii = join '', map {chr(oct"0b$_")} $bin =~ /(\d{8})/g;
  return $ascii;
}

=OUTPUT
bin   => 01010010011011110110110001100110
ascii => Rolf

Or, as one-liners..... 

perl -le 'print join"",map{sprintf"%08b",ord($_)}split//,pop' Rolf
perl -le 'print join"",map{chr(oct"0b$_")}pop=~/(\d{8})/g' 01010010011
+011110110110001100110
