问题
I have a problem with creating an XML file from inside a SQL PROCEDURE. The XMLs get created and placed in the correct folder. Although when I open the file in XMLSpy, it says the following error:
Your file contains 3 character(s) that should not be present in a file using the Unicode UTF-8 encoding... The offending characters are è (0xE8), ü (0xFC), é (0xE9)
When I open the XML file in Notepad++ and check for encoding (via menu Encoding on top), it says it is in ANSI and not in UTF-8.
So my question is: How do I get it to turn into UTF-8? Any suggestions? The code of my procedure can be found below:
@File VARCHAR(2000) // parameter
AS
BEGIN
DECLARE @OLE INT
DECLARE @FileID INT
EXECUTE sp_OACreate 'Scripting.FileSystemObject', @OLE OUT
EXECUTE sp_OAMethod @OLE, 'OpenTextFile', @FileID OUT, @File, 8, 1
DECLARE @Text XML
SET @Text = (SELECT TOP(1) [xml] from VW_WARP_LEVERANCIERS_XML)
EXECUTE sp_OAMethod @FileID, 'WriteLine', Null, @Text
EXECUTE sp_OADestroy @FileID
EXECUTE sp_OADestroy @OLE
END

Changed my code, exporting to ASCII instead of Unicode (as suggested below by Wolf), but this didn't help too. But here is that part of code:
DECLARE @OLE INT
DECLARE @FileID INT
EXECUTE sp_OACreate 'Scripting.FileSystemObject', @OLE OUT
EXECUTE sp_OAMethod @OLE, 'CreateTextFile', @FileID OUT, @File, 2, False
DECLARE @Text XML
SET @Text = (SELECT TOP(1) [xml] from VW_WARP_LEVERANCIERS_XML)
EXECUTE sp_OAMethod @FileID , 'Write', Null, @Text
EXECUTE sp_OAMethod @FileID , 'Close'
EXECUTE sp_OADestroy @FileID
EXECUTE sp_OADestroy @OLE
END

I found a solution via another way. (don't remember which website I found it) See code below. This code will export my file in UTF-8-BOM encoding.
@File VARCHAR(2000)
AS
BEGIN
DECLARE @OLE INT
EXECUTE sp_OACreate 'ADODB.Stream', @OLE OUTPUT
DECLARE @Text XML
SET @Text = (SELECT TOP(1) [xml] from VW_WARP_LEVERANCIERS_XML)
DECLARE @Converted NVARCHAR(MAX)
SET @Converted = CONVERT(nvarchar(MAX), @Text)
EXECUTE sp_OASetProperty @OLE, 'Type', 2 --1 = binary, 2 = text
EXECUTE sp_OASetProperty @OLE, 'Mode', 3 --0 = not set, 1 read, 2 write, 3 read/write
EXECUTE sp_OASetProperty @OLE, 'Charset', 'UTF-8' --'ISO-8859-1'
EXECUTE sp_OASetProperty @OLE, 'LineSeparator', 'adLF'
EXECUTE sp_OAMethod @OLE, 'Open'
EXECUTE sp_OAMethod @OLE, 'WriteText', NULL, @Converted --text method
--Commit data and close text stream
EXECUTE sp_OAMethod @OLE, 'SaveToFile', NULL, @File, 2 --1 = notexist 2 = overwrite
EXECUTE sp_OAMethod @OLE, 'Close'
EXECUTE sp_OADestroy @OLE
EXECUTE sp_OADestroy @OLE
END

Generally, SQL Server does not support UTF-8 by itself. However, I'm not sure about FSO, maybe it does.
The OpenTextFile documentation states that you can determine the file format, i.e. ASCII or Unicode. Try:
EXECUTE sp_OAMethod @OLE, 'OpenTextFile', @FileID OUT, @File, 8, 0;
This should give you an ASCII file format.
