I am trying to write characters to a file using their binary equivalents. To do this I am using pack: 
$bob=pack("B*",11101100);
print DATAFILE $bob;

[download]
Then I read the data back from the file and unpack it thus: 
$bobagain=unpack("B*",$stufffromfile);
$bobunpacked=unpack("B*",$bob);
print $bobagain;
print "\n$bobunpacked";

[download]
And they are equal, yes! So I then tried to write two bytes (which should be two characters in ASCII, or perhaps one if you use a unicode interpretation (which I eventually will)). 
$bob = pack("B*",1110110010010000);
print DATAFILE $bob;

[download]
and then did the same thing: 
$bobagain=unpack("B*",$stufffromfile);
$bobunpacked=unpack("B*",$bob);
print $bobagain;
print "\n$bobunpacked";

[download]
But they are not equal! 
from file:         111000111000010010000111
from $bobunpacked: 101101100100111110000000

[download]
and $bobunpacked isn't even what it should be! what is going on? I have absolutely no clue what is going on, can anyone help me with this?
