means the decoder does not check lengths.
You can specify up to 8 code lengths (maximum of 64 characters).
The code length includes the check character and the start and
stop characters. If you specify a code length other than 0, the
decoder will only decode labels with the number of characters
specified.

character ensures that the data is read correctly. The default is No,
which means the decoder treats all decoded characters as data.
The Codabar character is computed as a Modulus 16 sum of all
characters value as specified in the AIM specification USS-Codabar.
