I'm working on our sites Manufacturer area. I've placed some english RSS feeds, that we will display to our customers...
 
The coding in feeds is UTF-8, but our site is running in Central Europe ISO-8859-2.
 
Is any way to decode the UTF-8 feeds to the ISO-8859-2? Can You make a coding selection field into the Category's RSS options?

It looks like the coding is set in articles_rss.php in line 120 to ".CHARSET". You might try chanfing that to "ISO-8859-2" and see if it works?
