> I have used queryRunner to insert unicode characters succesfully in MSSQL and IBM DB2. I was not able to successfully insert unicode into Oracle. Instead I see the reversed questions mark are inserted, in place of the acutal data. This is the code. The below code works fine If I'm using SQL Server 2016 or IBM DB2 10.5. 
> 	
> Here is a sample java code I'm using. The followoing code works perfectly if executed against SQL Server database.
