SO_ATTACHMENT_READ_API1 xml attachment appears in chinese characters

Hi guys,

In a non-unicode system, the  SO_ATTACHMENT_READ_API1 FM exports out the the table attachment_content in the correct format.

However in a new unicode system, the same tables gives out chinese characters instead.

I can convert the it back to the correct XML format using FM SCP_TRANSLATE_CHARS but the subsequent processing logic in the program:

CALL TRANSFORMATION

             SOURCE XML

             RESULT

gives a conversion error.

How do I correct this?
