Resolution of Inconsistencies

Three types of inconsistencies could arise in the assignment of symbology options. The decoder has pre-
defined strategies to resolve these inconsistencies: If UPCE_as_EAN13 is true, then UPCE_as_UPCA
is ignored.
If symbology conversion is selected but the target symbology is not enabled, then the decoder still
outputs the symbol in the target symbology. For example, suppose UPC-E is enabled and
UPCE_as_EAN13 is true but EAN-13 is disabled. All UPC-E symbols will be shown as EAN-13 and
EAN-13 options (if specified) will be applied. For the two symbologies that have optional check digits,
Code39 and Interleave 2 of 5, the decoder will always transmit the check digit if the verification is
disabled.
