Export SQL View to Flat File with UTF-8 Encoding

I've setup a package in SSIS to export a SQL view to a flat file and it's working fine.  I now need to make that flat file UTF-8 encoded.  The package executes but still shows the files as ANSI encoded.

My package consists of a Source (SQL View) -> Derived Column (casts the fields to DT_WSTR) -> Destination Flat File (Set to output UTF-8 file).

I don't get any errors to help me troubleshoot further.  I'm running SQL Server 2005 SP2.
