OIC FTP adapter - erroing out with UTF-8-BOM encoding. Any workaround?

Summary:

OIC FTP adapter erroring out when the xml file is of UTF-8-BOM encoding. Works well when its UTF-8.

Content (required):

We have an issue while reading an invoice XML file where for a specific sender, the file is coming with UTF-8-BOM encoding. For majority of the senders, the encoding is UTF-8. We tried using the below change in the xsd schema and doesn't work.

xmlns:nxsd="http://xmlns.oracle.com/pcbpel/nxsd"

nxsd:parseBom="true" nxsd:version="NXSD" nxsd:stream="chars"

nxsd:encoding="UTF8"
