	 * *Code 39* 1D barcode symbology.

	 * @image html sample-code39.svg "Sample Code 39 Barcode"
	 *
	 *
	 * ### 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().
	 *
	 *
