It still couldn't work after I increased the number of ± to about 100. And the error rate after 2000 iterations is about 11. This is a pretty high error rate compare to what we have for adding a few characters to eng. With such high error rate, I would not be surprised that it could't recognize some special characters like ±. Is this it for chi_sim? Or can I increase iterations to make the error rate smaller? Thanks for your help.
