Bug in parsing passport with only one name about mrz HOT 3 CLOSED

Yes, it's correct. That should not happen.

As ICAO 9303-3 3.4 says:
"The name of the holder is usually represented in two parts, the primary identifier and the secondary identifier."

So I think that the right thing to do, in case of getting only one identifier, would be to report it as a warning.

Also, thanks to your report, I discovered that something similar happens in mrz.generator. When the primary identifier is not given, an incorrect output is got. For example:

from mrz.generator.td3 import TD3CodeGenerator

print(TD3CodeGenerator("P",           # Document type
                       "Utopia",      # Country
                       "",            # Surname(s)
                       "Anna María",  # Given name(s)
                       "L898902C3",   # Passport number
                       "UTO",         # Nationality
                       "740812",      # Birth date
                       "F",           # Genre
                       "120415",      # Expiry date
                       "ZE184226B"))  # Id number

This wrong output is got:

P<UTO<<ANNA<MARIA<<<<<<<<<<<<<<<<<<<<<<<<<<<
L898902C36UTO7408122F1204159ZE184226B<<<<<10

Next week I'll work to try to fix it

Thank you very much for your feedback

Thanks,
Also, the first example MRZ, is an instance of another false-positive, where optional data hash fails when optional-data is empty (all <) and optional-data-hash is < (instead of 0). I think it may be an error according to specs, but exists in real-world.

@tahajahangir , hi again!

_fields method at the beginning was very simple... then, little by little, I added more checks. That's why it had several errors. I almost rewritten it from scratch. I've tested it again and I think it works fine now, but if you find something wrong, I would appreciate it if you told me

Thank you so much!

PS: I have created a new issue with the 2nd problem you have reported.
