Hello, I'm trying to apply Tess4.0 to recongnize the simplified Chinese with the command as: argc = 13; argv[1] = "E:/数据库/yanghui_results/yanghui_100_0.jpg"; argv[2] = "E:/sample/01"; argv[3] = "-l"; argv[4] = "chi_sim+eng"; argv[5] = "-psm"; argv[6] = "7"; argv[7] = "--oem"; argv[8] = "OEM_TESSERACT_LSTM_COMBINED"; argv[9] = "--tessdata-dir"; argv[10] = "../tessdata"; argv[11] = "--user-words"; argv[12] = "../tessdata/chi_sim.user-words"; I have used the chi_sim and eng traineddata as the tessdata language, but some specific symbols, such as '∠' (means an angle), cannot be correctly recognized. For example, an image demonstrated in above is the input data of Tess4.0, and the results is shown as the following: 如图, 在口ABCD中, 点E, F在AC上, 且乙ABE=乙CDF, 求证: BE=DF, >From the results, we can observe that the '∠' symbol has been recognized as '乙', and the *rhomboid <?keyword=rhomboid> symbol is recognized as '口', '.' period symbol as ',' **comma <?keyword=comma> * *symbol <?keyword=symbol>.How to correctly recognized these specific symbols with Tess4.0? Can you help me?* -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
