Here is a patch (against 1.1.r14) that addresses exactly this issue (not the 
issue with the other characters mappings mentioned in the duplicate).

The was a bug in the previous patch, '@' was occasionally appended to the 
message. This one is good.

If you need both sending and receiving, use the patch here 
https://code.google.com/p/asterisk-chan-dongle/issues/detail?id=140. Everything 
works well but occasionally @ is appended to the received SMS (as described in 
the issue).
