I noticed that you are talking about the unicode support in the ROM, well, there are several chars in the ROM, you could modify it to support the code that you need, please see the details as below:

[HKCU\ControlPanel\PhoneExtendFunction\CDMA]
MsgType="2"

1: for 7 bits
2: for 7 bits+unicode;
3: for 8 bits
4: for 8 bits + unicode;

[HKEY_CURRENT_USER\Software\Microsoft\Inbox\Setting s]
"SMSUnicode"=dword:00000001

I saw the ENG ROMs have not the above reg., you could delete it as well.
