Feed description is converting to htmlentities

[dennis-hh]

I noticed that if an RSS feed provides a description field for an item, and this field contains special characters such as "ö ä ü ß", these are encoded to html entities ("öäüß"). The editor always has to fix this manually by setting the correct characters again.
This issue does not occur for the other fields (title, content). Those are correctly imported and special characters are retained.
The feed in question uses UTF8 encoding.
