Multi-lingual rss feed question

I paid a developer to write a script to generate an RSS feed for multiple languages for a site. My only question is that when I go to the URL for the XML that's generated, it doesn't show up in Korean, it shows up like...

I've never worked with multiple languages before, is there a header or something that should be added to this page? Is the <language> tag supposed to read <language>ko-kr</language> for Korean?

These are so called HTML entities. No header will change anything, as Korean characters (as well all the others) should be UTF-8 encoded. That's actually standard character encoding for XML and basically that's what should be used for multilingual RSS or ATOM feeds.
