I chanche all the iso-8859-1 entries in the code with UTF-8 so to support Greek languange.
It works but i have a strange problem:
In sidebar the categories links not working.
For example the link of one of the categories is http://newz.gr/index.php?category=
instead of the correct http://newz.gr/index.php?category=τεστ

Actually it missing the title of the category!

But does not happen the same problem for the category link that appears under of a story.

Any help please?

Thank you very much
