SQL data not retrieved in Unicode Hindi

[Pebble]

I am developing a web app in ASP.NET with C#. I am saving data in SQL tables as Unicode character as given by Google Transliteration. I am supposed to use Hindi. I have no issues regarding adding data. But when I use "SELECT" statements, no data is retrieved from the database tables in any case.My Query is as follows:\[code\]SELECT uid, family_head, member_name, house_no, address, f_h_name, gender, caste, dob, occupation, literacy, end_dateFROM familyWHERE (member_name = '????? ???????')\[/code\]It return null.
