Sorry to bother you again and again. I reduced the training text to about 450 lines, with like 30 ± in it. I used two fonts and iteration of 1000. But it looks like ± is still not picked up by the BEST OCR TEXT at all, it always recognizes ± as something else. What is happening here? Should I increase the number of ±? Or do I need to increase the number of fonts? I'm trying increasing iterations.
