FIX: Special characters are not written into the output document after they are processed by a send pipeline that uses the Flat File Assembler in BizTalk Server 2009

Consider the following scenario in Microsoft BizTalk Server 2009:
  • You create a custom send pipeline component that uses the Flat File Assembler component that is provided with BizTalk Server.
  • In an orchestration, you specify the character encoding of outgoing messages by setting the XMLNorm.TargetCharSet property in the message context.
  • You specify a character encoding that incorporates special characters. For example, you specify Windows-1252.
  • You create a send port that uses the custom send pipeline for the orchestration.
  • You receive an incoming message that contains special characters.
In this scenario, you may find that the special characters are written incorrectly into the output document. For example, you may find that "ó" or "á" in the incoming message is written as "?" in the output document.
This problem occurs because the character encoding set in the XMLNORM.TargetCharSet property on the message context is not applied correctly in the Flat File Assembler.
After you apply this hotfix, the character encoding that you set in the XMLNORM.TargetCharSet property in the message context will be applied correctly in the Flat File Assembler.
