FIX: The BizTalk Server HTTP Adapter pre-appends the byte order mark (BOM) to request messages in BizTalk Server 2004

This article has been archived. It is offered "as is" and will no longer be updated.
When an HTTP request message is encoded with a Unicode character set (UTF8 or UTF16), the Microsoft BizTalk Server 2004 HTTP adapter will pre-append the byte order mark (BOM) to the message before it sends the message out to the partner. The partner may not be able to recognize and process the BOM.
