I get this error on a File Destination Task, do you know what the cause is and how to fix it ?

Package Validation Error


Error at export data to csv [Flat File Destination [187]]: The code page on input column "..." (958) is 1252 and is required to be 65001.

The issue is caused by a clash in code pages between 1252 (i.e. Windows-1252) in SQL Server and 65001 (i.e. UTF-8) that your CSV file is expecting.

I believe one solution to the issue would be to CAST your source columns to NVARCHAR in the initial SELECT from the database, or use a Data Conversion task to convert them to Unicode strings.

An alternative would be set the code page in the Flat File Connection Manager to 1252 ANSI - Latin.

    yes, it worked in both ways, convert to NVARCHAR , but also using Data derivation task. I have not tried to set the Flat File Connection Manager to 1252 ANSI - Latin. Thanks a lot! Dec 11, 2014 at 12:54

    SQL Server is such a stupid engine. Of course varchar is a subset of nvarchar. I don't get it why it needs an explicit cast. Sep 26, 2017 at 8:08

I had the same issue where My error was as follows:

The code page on Flat File Destination.Inputs[Flat File Destination Input].Columns[Number] is 65001 and is required to be 1252.

Then I was doing google and I found very interesting and correct results from the below website: Here in the question, itself answer is given. After that, I just change code-page-1252 in flat-file property from connection manager and it worked for me
