For help using Google zxing generate pdf417 bar code is the code in Chinese libraries-CodePudding

Use it library, input Chinese content, generate bar code, with software that sweep the bar code, it is garbled, someone who knows English and Numbers are normal, could you tell me how to solve?

 
Map Hints=new HashMap<> (a); 
Hints. The put (EncodeHintType CHARACTER_SET, CharacterSetECI UTF8);//set the coded character set utf-8 
Hints. The put (EncodeHintType MARGIN, MARGIN); 

BarcodeFormat format=BarcodeFormat. PDF_417; 
//create a matrix object 
BitMatrix BitMatrix=null; 
Try {
//generate corresponding bit matrix qr code object 

BitMatrix=new MultiFormatWriter (.) encode (contents, format, width, height, hints); 

} the catch (WriterException e) {
e.printStackTrace(); 
} 

//set a matrix image of parameter 
MatrixToImageConfig config=new MatrixToImageConfig (Color. Black. GetRGB (), Color. White. GetRGB ()); 
//a matrix object BufferedImage objects 
BufferedImage qrcode=MatrixToImageWriter. ToBufferedImage (bitMatrix, config); 
ImageIO. Write (qrcode, "PNG", the new File (" E:/111 PNG "));
