Replacing a specified nvarchar string in database column with a carriage return in sql-ce

Question

When not using the nvarchar and replacing with another string i.e.'test' I get the expected replacing results. I am attempting to insert a carriage return

private void reformatData(SqlCeConnection conn)
    {
        try
        {
            SqlCeCommand comm = new SqlCeCommand("UPDATE database " + "SET column = replace(MoodLog, '[ret]', nvarchar(13));", conn);
            comm.ExecuteNonQuery();
        }
        catch (SqlCeException ex)
        {
            MessageBox.Show(ex.ToString());
        }
    }

Answer 1

Use the nchar function, no nvarchar function with SQL Server Compact:
