Train Tesseract 4.0 for Urdu Nastaleeq fonts

[gupta....@tftus.com]

I am trying to train Tesseract for Urdu Nastaleeq fonts. I used 10 Text files of total 1 MB and gave them to the jTesseract editor to create box files and then create traineddata file. But It gives an error: Error: unichar ╪¿╪¼╪º in normproto file is not in unichar set. The output that comes is also very inaccurate. Can somebody help me with this?

I am using automated way of generating files like .unicharset file , .normproto file, inttemp file etc.which ultimately gives Traineddata file. I am using JTesseract Editor utility.

I gave it my text files and It generated Traineddata and rest other files for me. But when I give nastaleeq input file, It gives Error: unichar ╪¿┌⌐█î in normproto file is not in unichar set  and generate garbage output.

If you want to train for 4.0 version, you should follow training instruction for 4.00 version. 

If you decide to go your own way, it is fine, but please do not claim that official instruction does not work for you, or output is very inaccurate.
