Problem reading a datamatrix barcode



The attached datamatrix barcode contains group separators (GS and US, respectively ASCII 29 and ASCII 31).

The problem is: when i want to read this barcode, the separators are also being returned as their ascii code in plain text!!! For example, Aspose will return
instead of:
20 21 22

I tried to read the barcode with a library named DataMatrix.Net. The result I get is:

which is not perfect but at least I can replace the unicode representation of the separator with a space for example.

I tried to play with a lot of Aspose.Barcode library parameters, without any success, I always get 29's and 31's returned.

Is there a way to disable this behavior or is this a bug?

My code snippet:

public List Extract(Stream data)
var values = new List();
using (var bitmap = new Bitmap(data))
using (var reader = new BarCodeReader(bitmap, DecodeType.DataMatrix))
while (reader.Read())
var value = reader.GetCodeText(Encoding.UTF8);

return values;

Best Regards,
