Prit,
I'm having problems with the RSS function. As far as I tested the script with english posts everything went ok, but now in spanish I guess accented characters are the cause.
In nicEdit's source code, accented chars are written as Á not Á
I tried to change encoding in the rss function from ISO-8859-1 to UTF-8 but no luck.
Besides posts content, accented chars in the meta description also invalidate rss.
I left a post with an accented word on my test blog you can check

Any suggestion ? :)
