How to recognize ￦?

[ahnHeejune]

I want to recognize korean currency symbol in menu table. But the ￦ is not included in korean character sets. When i try samples some time recognized as W and some time 8 or other characters.

Should I retrain finetune the model? And if i have to how to add the new characters? Should I modify the number of output of last layers of recognizer?

I hope we could find some solution without restructoring the model and retraining. Please let me know how to do it.
