Tesseract 4.1.0-beta1

All trained data for 4.0 dont work except 3.04.00. Unfortunately, the accuracy and confidence of 3.04.00 is very bad. Where can i find an accurate trained data for this version?

First I set properties to ‘Copy Always’. It didn’t work. I was able to get this working by restarting visual studio. Thanks.

I noticed all the trained models do not recognize MRZ characters on passports or IDs. Characters such as <<<<<<< is either represented by kkkkkkkk or LLLLLLLLL. Sometimes CCCCCCC.

Is there a way to add more training to the model or get a better trained model. My primary use case of tesseract is for passports and identity cards containing MRZ.
