**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?
