SFTP adapter UCS-2

Hello,

I have a scenario from File to proxy.

The file is in a SFTP server with a UCS-2 format.

In the message mapping it appears this message:

"BaseRuntimeException:An invalid XML character (Unicode: 0x0) was foundin the element content of the document."

As charset i have put UTF-8, UTF-16, ISO-8859-9, but with all of them it shows the same error.

Any idea?

Thanks
