Describe the bug Special characters are allowed in Code 93 Extended like "", but in mlkit app will not recognize the special character and showing "bO" if this is a "" character. However, in zxing app it can recognize the "_" correctly. Is there any setting it can be used to recognize these special characters?

To Reproduce Example Steps to reproduce the behavior in sample app:

  1. Go to https://products.aspose.app/barcode/generate/code93#result
  2. Select 'Code 93 Extended'
  3. Enter '123_456' in code text
  4. Click on 'Generate Barcode'
  5. Use the sample app 'Barcode Scanning' function to scan the barcode
  6. See incorrect result '123bO456'

If applicable, please include code snippet and sample input(image, video, text, etc) image image

Expected behavior A clear and concise description of what you expected to happen. Showing correct result '123_456'

ML Kit does not currently claim to support Code 93 Extended, only Code 93.

Nevertheless, the decoding is incorrect. The correct behaviour when encountering the implicit (%) codeword is not to scan when lacking support for extended characters.

So this seems to be both a bug report and a feature request.
