Hi me again, I attached another image which is quite similar, but in this case tesseract fails to detect the correct output in any way, so not even using the tesseract exe, with psm set to 8 or leaving it as auto Has anybody got an idea why? Does this mean one has to teach tesseract to read this character correctly?
