Problem with UTF8. italian/russian characters

The content you get is not utf-8 encoded or the encoding is damaged by the importer. Usually SimplePie – the feed reader WordPress uses – is quite good at handling such cases. I wonder what an importer you use …

Anyway, I’ve written a function to enforce utf-8 output. You should implement this very early in the import process. The article is in German – let me know if I should add more explanations here.
