I just found a weird behaviour when attempting to extract a string from the Binary-table in the MSI.

I have a file containing "Hello world", the data I get is "???Hello world". (Literary question mark.)

Is this as intended?
Will it always be exactly 3 characters in the beginning?

Regards Leif

[CustomAction]
public static ActionResult CustomAction2(Session session)
{
    View v = session.Database.OpenView("SELECT `Name`,`Data` FROM `Binary`");
    v.Execute();

    Record r = v.Fetch();
    int datalen = r.GetDataSize("Data");
    System.IO.Stream strm = r.GetStream("Data");
    byte[] rawData = new byte[datalen];
    int res = strm.Read(rawData, 0, datalen);
    strm.Close();

    String s = System.Text.Encoding.ASCII.GetString(rawData);
    // s == "???Hello World"

    return ActionResult.Success;
}
