getting blank spaces or question marks when generating arabic images

[GhulamMustafa0324]

I am trying to train easyOCR on arabic images, I used this command trdg -c 1000 -l ar -w 5 -f 64 -k 5 -rk to get the images, they are generating but they do not have any text in the image instead either only blank spaces or question marks, although the file name has the arabic text in it.
