Read XLS file with UTF-8 character;

I am using this script that is working. But in unity i can’t get the strings from the shells. The are greek characters like “Κάλη μέρα” but i get “??? ???”.

How i can get thisd work?

i try this but din;t change anything.

string con = “Driver={Microsoft Excel Driver (*.xls)};characterEncoding=UTF-8;CharSet=UTF-8;DriverId=790; Dbq=”+filetoread+“;”;

the script i get it from :
http://wiki.unity3d.com/index.php?title=Load_Data_from_Excel_2003

void readXLS( string filetoread)
	{
		// Must be saved as excel 2003 workbook, not 2007, mono issue really
		string con = "Driver={Microsoft Excel Driver (*.xls)}; DriverId=790; Dbq="+filetoread+";";
		Debug.Log(con);
		string yourQuery = "SELECT * FROM [Sheet1$]"; 
		// our odbc connector 
		OdbcConnection oCon = new OdbcConnection(con); 
		// our command object 
		OdbcCommand oCmd = new OdbcCommand(yourQuery, oCon);
		// table to hold the data 
		DataTable dtYourData = new DataTable("YourData"); 
		// open the connection 
		oCon.Open(); 
		// lets use a datareader to fill that table! 
		OdbcDataReader rData = oCmd.ExecuteReader(); 
		// now lets blast that into the table by sheer man power! 
		dtYourData.Load(rData); 
		// close that reader! 
		rData.Close(); 
		// close your connection to the spreadsheet! 
		oCon.Close(); 
		// wow look at us go now! we are on a roll!!!!! 
		// lets now see if our table has the spreadsheet data in it, shall we? 
 
		if(dtYourData.Rows.Count > 0) 
		{ 
			// do something with the data here 
			// but how do I do this you ask??? good question! 
			for (int i = 0; i < dtYourData.Rows.Count; i++) 
			{ 
				// for giggles, lets see the column name then the data for that column! 
                Debug.Log(dtYourData.Columns[0].ColumnName + " : " + dtYourData.Rows*[dtYourData.Columns[0].ColumnName].ToString() +* 

" | " + dtYourData.Columns[1].ColumnName + " : " + dtYourData.Rows*[dtYourData.Columns[1].ColumnName].ToString() +*
" | " + dtYourData.Columns[2].ColumnName + " : " + dtYourData.Rows*[dtYourData.Columns[2].ColumnName].ToString());*
* }*
* }*
* }*
