I personally would rather use DBD::SQLite for such a problem, but it sounds like you are using pack, no? If that is the case, are you packing/unpacking with 'a' or 'A'? 
my @data = (
  'thrakb    boom ',
  'a d j k l j s f',
  '012345678901234',
);

foreach (@data) {
   print 'a unpack: ', join('|', unpack('a5a5a5',$_)), "\n";
   print 'A unpack: ', join('|', unpack('A5A5A5',$_)), "\n";
}

my @record = (
   [qw(123 blah 21)],
   [qw(45 sadflkj 9)],
   [qw(4532 j 99)],
);

foreach (@record) {
   print 'A pack: ', pack('A4 A10 A2',@$_),"\n";
   print 'a pack: ', pack('a4 a10 a2',@$_),"\n";
}

Try packing with 'a' instead of 'A'. Note that packing with 'A' will add trailing whitespace: 

           a                         A
  pack  does not add space     adds trailing space
unpack  does not remove space  removes trailing space
Update: added pack example, prolly what i should have used instead of the unpack example. ;)
