My customer is using Data Matrix bar code which contains ISO/IEC 15434 characters,These specific ASCII characters are termed "non-printable control characters". For a example, Group Separator=0x1D.(http://en.wikipedia.org/wiki/Group_separator#Field_separators) I need to locate these characters to judge which data should be sent.the data longth is not constant. So I have to located them in DataWedge. I noticed that 123Scan2 can do it with "Move to" command folllowed by "Special characters" option. But the same command in DataWedge can only followed by "Strings". Any suggetion will be very appreciated.
