in reply to Re^2: Convert ASCII string to 7-bit binary string
in thread Convert ASCII string to 7-bit binary string

Mea culpa; I should pay more attention, and not just assume that two similar-looking binary strings are, in fact, the same. Thanks for the correction.

Fortunately it's easily-fixed; just use substr in the substitution to chop off the first character: 

($out = $string) =~ s/(.)/substr unpack('B8', $1), 1/eg;

    Seems like a weird way of writing the following to me: 
    $out = map { substr unpack('B8', $1), 1 } $string =~ /./g;
