Skip first line of an XML- PI 7.0

Hi Experts,

I am working on SAP PI 7.0 and File to Proxy scenario.

I need to read a XML file and send to ECC via Proxy..everytime it is failing in mapping because it has "UTF-16" in it as shown below.

<?xml version="1.0" encoding="utf-16"?>

this is not supported and hence i need to either change it to UTF-8 or remove this first line of an XML while reading from FTP only then it works.

Can someone please help me in doing this.

No FCC here..it is a plain XML file.

Thanks
