Carriage Return on Barcode 128 in Javascript

Hello,
I would like to request advice on AEM Forms with Barcode 128. To generate Barcode 128 on Form, I will require to show "|" character and Carriage Return but barcode was not generated with both in data.
- What is carriage return for javascript syntax of Barcode 128? Barcode 128 with javascript can not use "\n" or "\r" or "\012" or "\015" for carriage return.
- For Barcode 128A can use with Carriage Return but missing "|" : What is syntax for "|" on Barcode 128A? When Text data initial with "|" on Barcode 128A, it was removed in Barcode.

For example :
Barcode.rawvalue = "|" + xxx.rawvalue + "\n" ;

I hope if advise can be provided via this support channel.

Regards,
Toom
