magpierss return garbage text from utf-8 xml after parsing

Question

I have been using MagpieRSS to get feed from an xml file.XML file is in UTF-8 character encoding (language = 'ja,jp').

But after parsing the xml, Magpie returns garbage string not japanese characters.

How do I tell Magpie to return UTF-8 format to get the right japanese characters i need?
