Need to Revise version of SQL Server generated XML - sql

Question

The following lines of code generate me an XML file looking like the below set, which is almost acceptable to my client. I say ALMOST because the one change I need to to have <?xml version="1.0" encoding="UTF-8"?> versus the standard <?xml version="1.0"> which is at the top of every XML file I generate using the EXEC xp_cmdshell command below. I essentially need <?xml version="1.0" encoding="UTF-8"?> instead of <?xml version="1.0">. Can someone please tell me how this can be accomplished?
-- SQL CODE USED TO GENERATE XML FILE - Using XML Path
SET #FileString = #FileName + '.xml" -S ALSCG-JPATHIL\SQLEXPRESS -T -c -t,'
SET #SQLSTRING = 'bcp ";WITH XMLNAMESPACES (DEFAULT ''urn:CP-xml'') select A.TargetSystem AS ''Header/Target'' from [Header] A FOR XML PATH(''Qty'')" queryout "C:\Program Files\'
SET #SQLSTRING = #SQLSTRING + #FileString
EXEC xp_cmdshell #SQLSTRING
-- XML FILE CONTENTS GENERATED - Missing the Encoding Condition here
<?xml version="1.0">
<Qty xmlns="urn:CP-xml">
<Header>
<Target></Target>
</Header>
</Qty>
-- XML FILE CONTENTS DESIRED - Note only difference is the Encoding!
<?xml version="1.0" encoding="UTF-8"?>
<Qty xmlns="urn:CP-xml">
<Header>
<Target></Target>
</Header>
</Qty>

The very last response in this link has the only "solution" to this problem that I've been able to find
Hi, (late response but might help someone in future) VARBINARY did not
work for me, probably 'coz of the my datasource didn't comply. Heres
what worked for me at the SQL end;
1) Store your raw xml data as VARCHAR or TEXT (instead of NVARCHAR or
NTEXT) into a variable,
2) Read this variable into the xml data type using utf-8 encoding.
Something like:
DECLARE #TempHTMLText
SET #TempHTMLText = --your raw xml data DECLARE #XMLDataText XML
SELECT #XMLDataType = '<?xml version="1.0" encoding="utf-8" ?>' + #TempHTMLText
I don't think you'd need to do exactly that, rather use the following query:
DECLARE #Xml XML;
WITH XMLNAMESPACES(DEFAULT 'urn:CP-xml')
SELECT #Xml = (select A.TargetSystem AS 'Header/Target' from [Header] A FOR XML PATH('Qty'));
SELECT CONCAT('<?xml version="1.0" encoding="utf-8" ?>', CAST(#Xml AS VARCHAR(MAX)))
Note that in my testing, I was unable to convert this data back to XML while preserving the encoding tag. That seems to be enforced explicitly by the XML data type
