Code 93 Extended
Using Code 93's "Full ASCII Mode", it is possible to encode all 128 ASCII characters. This is accomplished by using the ($), (/), (%), and (+) symbols as "shift" characters. These characters combined with the single character that follows indicate which Full ASCII character is to be used.
The following property is specific to the Code 93 Extended type and available in the Properties panel under the Symbology property:
Calculate a Checksum
Specifies whether to calculate a checksum for the bar code.
A checksum of a Code 93 Extended bar code can contain characters that are not supported by this bar code symbology. For this reason, the checksum is not included in the Code 93 Extended bar code's displayed text.
