If you try to generate the dataMatrix barcode for the string " SC-BURIT006-12/07/2012-00250 " the produced barcode will lost the last 4 characters.
You can test it in the Demo Applet page.
The same string produce correct barcode with other generator services (e.g. http://datamatrix.kaywa.com/img.php?s=12&d=SC-BURIT006-12%2F07%2F2012-00250 , the images are really different!).
Have the similar problem with following text
PALPHA45624-01BLK>SNAPEX0001>4LCA>10D121408>VAPEXC02CD
produced result is
PALPHAO0R4G9H09BLK>SNAPEX0001>4LCA>10D121408>VAPEXC02CD
