unicode sms problem...
 

I am using calkulin's rom right now.
The problem is that I can't send unicode sms (Korean).
Whenever I send mgs to myself, it appears ??
I installed Korean and my regional setting is Korea.
I can read and write but it doesn't work for sms.
I tried this with my bell rom, mightyrom. both of them not working.
Can anyone help me with this?
