Hi Agnes,

I know my English is poor and can cause confusion.

Yes it is correct that the EAN-128 (UCC or GS1) uses the same table as the code 128.

The difference is the structure, and we're working on it with FoxBarcode, and also work on human reading is very important in this code.

We are based on documentation of GS1 and local agencies, such as:
http://www.gs1tw.org/twct/gs1w/download/GS_Section_5-3_V7.pdf

We (Guillermo and I) we also have our discussions, such as how far FoxBarcode monitor and validate the structure, or we leave that task to the user.
