title: c# use non-printable characters asp.net mvc
body: <p>I've to read datamatrix barcodes (vda 4902, gtin, gs1) which use non-printable chars as seperator.
  The goal is to scan the barcode with intermec or honeywell hardware and send it to a c# mvc webapplication. 
  The printable characters are received by the webapplication, but the non-printable chars not.
  I've scanned the code to the VI editor on a linux server - bere i can see the special characters. But i couldn't get it with a asp.net to work nor a c# windows form application.</p>
  
  <p>So currently i don't know where to look at...</p>
