How to have ZWNJ characters in Tags?

Question

My site is in Persian which is a non-latin language. In the Persian language, we use zero-width non-joiner (ZWNJ) for typping words such as بی‌باک (withou the zwnj it looks like بی باک). The problem is that the Tags filed doesn't accept the zwnj character. In other word, when I insert بی‌باک in the Tags filed, it gives me two separate tags: بی and باک.

Is there a way to solve this problem?

Go to :

Admin ---> General ---> Posting

and select "Use comma as the only tag separator".
