Localization :: Reading A CSV File Created By Excel?

I am reading a CSV file created by Excel. the string I am reading needs to be encoded (it shows small boxes instead of hebrew characters) so I wrote a lil routine to convert the string -

Function encodeName(ByVal name As String) As String
Dim src As Encoding = Encoding.UTF8
Dim dest As Encoding = Encoding.Default
Dim srcBytes() As Byte
srcBytes = src.GetBytes(name)
Dim asciiBytes() As Byte = Encoding.Convert(src, dest, srcBytes)
Dim mychars(dest.GetCharCount(asciiBytes) - 1) As Char
dest.GetChars(asciiBytes, 0, asciiBytes.Length, mychars, 0)
Dim asciiString As New String(mychars)
End Function

From what I read FileStream.ReadLine reads the text with encoding UTF8 so I try to convert from UTF8 to Encoding.Default buy instead of little boxes I get question marks.
