   Hi All,
      I was testing the functionality to use string delimiter and found the following issue.
      
      ```
   public static void main(String[] args) throws Exception{
           String row = "a||b||c||d";
           StringBuilder stringBuilder = new StringBuilder();
           try (CSVPrinter csvPrinter = new CSVPrinter(stringBuilder, CSVFormat.EXCEL);
                CSVParser csvParser = CSVParser.parse(new StringInputStream(row), StandardCharsets.UTF_8, CSVFormat.Builder.create().setDelimiter("||").build())) {
               for (CSVRecord csvRecord : csvParser) {
                   for (int i = 0; i < csvRecord.size(); i++) {
                       csvPrinter.print(csvRecord.get(i));
                   }
                   System.out.println(stringBuilder.toString());
                   //Expected : a,b,c,d
                  // Actual : a,b|c,d
               }
           }
       }
   ```
   
   The actual value is different from expected, looks like the string delimiter doesn't work as expected when there is an empty column.
   Can some1 please confirm
