SSIS: Change Code page 1252 ANSI to UTF-8 65001

Hi All;

I have created SSIS Package to import data from OLE DB to a flat file. The code page in the flat file connection manager was set to default 1252 ANSI - Latin I. Now I have been asked to output the flat file in UTF-8 format. I have changed the code page to 65001 UTF-8 but the package will not run. I got the following message:

the code page on input column COLUMN_NAME (184)is 1252 and is required
to be 65001

I have searched around and i have read that i need to change the column data type from VARCHAR to NVARCHAR!! Is this the solution?

Is there is any other option? Thanks.
