Thanks for spotting this! I understand why it makes this error, but it will take some thought to fix it properly! It is using a sort by x-position to re-order the boxes for RTL language training, but that doesn't work in the case of heavily kerned characters like ل in your example. It needs to simply reverse the RTL characters, but has to avoid messing up the order of the common script, which is why I was using a sort to begin with. https://github.com/tesseract-ocr/tesseract/blob/master/training/boxchar.cpp#L202
