JavaMail and non ASCII characters in file names

I can send attachments with non ASCII file names in JavaMail, but I can't download them I specifically get Java. Java for attachments whose file names contain non ASCII characters io. FileNotFoundException.

For reference only: I am using a similar messagebodypart Setfilename (mimeutility. Encodetext (filename [i]) to encode text and mimeutility Decodetext (bodypart. Getfilename()) to decode non ASCII file names

Is there a solution?

Edit @ bill, this is part of my code, read the attachment I also added properties to my code Setproperty ("mail. Mime. Decodeparameters", "true") and properties Setproperty ("mail. Mime. Decodefilename", "true") property

if (message[a].getContent() instanceof MimeMultipart) {
                Multipart multipart = (Multipart) message[a].getContent();
                for (int i = 0; i < multipart.getCount(); i++) {
                    bodyPart = multipart.getBodyPart(i);                     
                    disposition = bodyPart.getDisposition();                    
                    if (disposition != null && (disposition.equals(BodyPart.ATTACHMENT) || (disposition.equals(BodyPart.INLINE)))) {
                        DataHandler handler = bodyPart.getDataHandler(); 
                        String path = bodyPart.getFileName();
                        String[] str = path.split("/");                         
                        String fileName = str[str.length - 1];                       

                        String filePath = ReadConfigPropertiesFile.getPropertyValue("server.buildpath");
                        System.out.println(fileName);
                        File tempDir = new File(filePath + user);
                        if (!tempDir.exists()) {
                            tempDir.mkdir();
                        }
                        File saveFile = new File(tempDir + "/" + fileName);
                        int count = 0;
                        while (saveFile.exists()) {
                          count++;
                          saveFile = new File(tempDir + "/" + count + "_" + fileName);
                        } 

                        bufferedoutputstream bos = new bufferedoutputstream(new FileOutputStream(saveFile));
                        byte[] buff = new byte[2048];
                        InputStream is = bodyPart.getInputStream();
                        int ret = 0;
                        while ((ret = is.read(buff)) > 0) {
                            bos.write(buff,ret);
                        }
                        bos.close();
                        is.close();
                        //System.out.println(bodyPart.getContentType());


                    }else {
                        //display body (message) of the attachment;
                        //System.out.println(bodyPart.getContent().toString());

                   }
           }
     }

The above code raises a FileNotFoundException on the line bufferedoutputstream BOS = new bufferedoutputstream (savefile)), and this is raised for attachments with file names of non ASCII characters (similar to ሰ ላ ም. PDF) Everything else is fine

Solution

This answer is taken from the comment of @ semytech (OP) It's hard to find it there, so I'll add it as a more visible answer It helps me use Hebrew file names

MimeBodyPart attachment = new MimeBodyPart();
attachment.setFileName(MimeUtility.encodeText(filename,"UTF-8",null));
