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.
