The [Order Date] column is being read as non unicode.
You could cast it to unicode in your select statement
e.g. SELECT CAST([Order Date] AS NVARCHAR(20)) AS [Order Date]
FROM MyTable
Ideally though, especially where dates are concerned, you should preserver the datetime datatype where you can. In other words the source column should be DATETIME column and the excel column should be a DATE format too. This should help you avoid the regional/locale issues that rear their head so often in ETL.
