In current version if you try to add a GS1-C128 barcode with an initial FNC1 char and using dynamic C128 you will get the following error:

"System.Exception: EC128-3: Could not insert start and code characters. Message: EC128-2: Could not determine start character."

This fix allows the FNC1 char to be added to the start of the barcode.

Resolves #179

Merged my branch with master and fixed tests that is failing.

New take is to replace the FNC1 char with FNC1 codeword instead. Seems to work better.

After testing realized that FNC1 wasn't properly added on a dynamic barcode. Will update this
