I am not sure I get it totally. If bit "1" is set is then the last byte in the record always realated to multibyte characters?

My code now is the following and I wondered if this is a correct understanding of it:

                eval {
                    sub min { return ($_[0]<$_[1]) ? $_[0] : $_[1] }
                    my $maxi = min($#$recs, $header->{'records'});
                    for( my $i = 1; $i <= $maxi; $i ++ ) {
                        my $data = $recs->[$i]->{'data'};
                        my $len = length($data);
                        my $overlap = "";
                        if ($self->{multibyteoverlap}) {
                            my $c = chop $data;
                            print STDERR "I:$i - $len - ", int($c), "\n";
                            my $n = $c & 7;
                            foreach (0..$n-1) {
                                $overlap .= chop $data;
                            }
                        }

                        $body .= _decompress_record( $header->{'version'},
                                                     $data );
                        $body .= $overlap;
                    }
                };

Why is three bits used for the size if the maximum size is 3? (I see now that I have reversed the order in $overlap).
