         * ### Input Data Format ###
         *
         * The extended *Code 39* barcode type supports the full 7-bit ASCII
         * character set (0-127).  This support is accomplished by encoding
         * lower case letters, constrol characters, and special characters
         * other than "-" and "." as two character sequences as illustrated
         * in the following table:
         *
         * | Dec | Char | Enc || Dec | Char | Enc || Dec | Char | Enc || Dec | Char | Enc |
         * |----:|:----:|:---:||----:|:----:|:---:||----:|:----:|:---:||----:|:----:|:---:|

         *
         * ### Checksum Property ###
         *
         * If the *checksum* property is *true*, a modulo 43 check digit will be
         * automatically generated and appended to the 1st pass encoded data
         * prior to the 2nd pass *Code 39* encoding. By default, the check digit
         * will not be generated.
         *
         * See setChecksum().
         *
         *
         * ### Show Text Property ###
         *
         * If the *Show Text* property is *true*, the original ASCII input data will
         * be printed below the barcode.  By default, the data will not be printed.
         *
         * See setShowText().
         *
         *
