Who offered scripts and different options to try.
Most of the options I had already tried, so I dug a little deeper into
the software on the PC and found that it was converting nulls and other
control chars to PC friendly characters like spaces and carriage
return/line feed pairs thus causing the conversion confusion.
Many Thanks
