I have clicked all fonts for testing and copy to OCR NETWORK , still failed to recognise TOTAL

Sir,

I use X code 9 , iOs 11 iPhone 6 to test. I scan receipt and hand writing TOTAL to see if it works.

Even I click all fonts with 100% accuracy tested to recognise "TOA" , it is still hard to recognise TOTAL.

Would you please tell me any limitations for such project . see if we can work together to improve this.
