There is much improved version of awk called "perl" and it has something called hashes. Code snippet would look something like this:

my %Godot;

while (<>} {
  chomp;
  if (/\'([^\']+)/ {

     next if  exists $Godot{$1};
     $Godot{$1}=undef;

  }
}
foreach (sort keys %Godot) {
  print "$_\n";
}
