         *
         *
         * ### Input Data Format ###
         *
         * The *Code 39* specification defines 43 characters, consisting of upper
         * case letters (A-Z), decimal digits (0-9), space, and several special
         * characters (-.$/+%). The BarcodeCode39 validator will also accept
         * lower case letters (a-z).  The encoder will automatically upshift
         * any lower case letters prior to encoding.
         *
         * For full ASCII support see BarcodeCode39Ext.
         *
         *
         * ### Checksum Property ###
         *
         * If the *checksum* property is *true*, a modulo 43 check digit will be
         * automatically generated and appended to input data before encoding.
         * By default, the check digit will not be generated.
         *
         * See setChecksum().
         *
         *
         * ### Show Text Property ###
         *
         * If the *Show Text* property is *true*, the input data will be printed
         * below the barcode.  By default, the data will not be printed.
         *
         * See setShowText().
         *
         *
