XML loader and UTF-16 - throws Content is not allowed in prolog

Hi,

Our ECC system is updated to unicode system recently. Now the iDoc downloaded from ECC is having a tag <?xml version="1.0" encoding="utf-16"?>.

The XML Loader in the transaction throws an exception "Cannot perform action on XML document Content is not allowed in prolog. Exception: [Content is not allowed in prolog.]". If I change the encoding manually as "utf-8" and executing the transaction, it is working fine.

Please let me know how to solve the issue.

Thanks,

Raman N
