MicroPDF417 Not Encoding ASCII Lower Than Decimal 32
Hello, we have a need to encode non-printable ASCII characters (characters 0-31 decimal) in a microPDF417 symbol. We are using the Java Barcode Library to do this. We have applyTilde set to true and have verified that using the tilde code does work for printable ASCII characters, but still does not work for non-printable characters. We are using a scanner that outputs the hex value for non-printable characters and have verified with other symbologies created with the IDAutomation libraries. Below is a sample test to show the behavior. I am attaching the output images that I receive when this test is run with both the record separator character (decimal 30) and an ampersand (decimal 38).
