Any new development on this issue?
I have this exact issue and if there's a fix/workaround, I want it.
I have this USPS delivery confirmation barcode that needs a FNC1 character in certain positions.
In PP3 I had this put in with a c128('\206')
In PP4 this workaround did not work and I had to convert my barcode object into a PP talk object.
I also had to construct the sum-control myself.
So far I did not notice the blanks, because they only appear on and off, but recently I have them on every barcode, because we change the DUNS number to a new one that contains the "95" number.
I needed this barcode converted to PP talk object to create the USPS delivery confirmation barcode.
If there's a fix where can I get it?
