getting an XML file from a web page encoding type

Hi all!

I done a schenario that get an XML file from a web page.

Michal Krawczyk 's blog was helped me.(http://scn.sap.com/community/pi-and-soa-middleware/blog/2012/01/05/michals-pi-tips-exchange-rates-from-an-xml-file-on-a-web-page--rest-axis) asynchronous scenario(SOAP-PI-File)

But I have a problem that about coming XML encoding type.

For example :

from PI payload : <Type>��zel</Type>

true form:<Type>Özel</Type>

How can I change encoding type?

Thanks
