Characters in Barcode Streaming Product Not Showing


We are using the Dynamic Barcode Generator Subscription and absolutely love how it is a single solution to add barcodes to many of our programs.

We are trying to pass (in this case Code 128 with Process Tilde, PT=T, enabled and using the Tilde Method for special characters):

ABC123~001~002~003~004~005~006~007~008~009

But the HR (human-readable text under the barcode) only shows ABC123:

When scanned using the IDAutomation 2D USB Barcode Scanner (SC7-USB) into the Free Barcode Scanner ASCII String Decoder, the scan shows:

ABC123<SOH><STX><ETX><EOT><ENQ><ACK><BEL><BS><HT>

Please help!

Operating System: Windows, Mac OS X, Linux, Unix

Application: Many

Best Answer

To verify the correct encoding of non-printable ASCII characters, IDAutomation recommends testing the result with the Barcode Decoder App because it reveals these characters in the result.

When using Code 128 'auto' (without having a subset specified), Process Tilde (or Apply Tilde), and formatting the data using the Tilde Method (often seen in GS1-128 encoding), the barcode is designed to only show the printable part of the HR (human-readable text under the barcode).

The barcode will have the non-printable characters encoded (by using the format ~??? for ASCII decimal characters) in the barcode, which can be seen using a scanner (like the SC7-USB or SC5-USB, with the lower ASCII option enabled) and an ASCII decoder as characters surrounded by <>.
