Postgres (EUC - JP encoded ) with Unicode MFC Application

I have an MFC application built with unicode characterset enabled (so CString and the MFC API's expects wide characters) and the postgres db as backend which is EUC - JP encoded. 

Iam accessing my DB using CRecordset for reading the tables and direct query execution using ExecuteSQL for updation., Both these MFC functions expects wide strings of 2 bytes but my DB is multibyte encoded of 1 byte. Can anyone please let me know how to handle this scenario of Unicode application with multibyte encoded DB.

Thanks
