When I put http://en.wikipedia.org/wiki/Chrząszcz it ought to be "turned into links automatically", but isn't. The aogonek tricks the forum. BTW double square brackets work
http://en.wikipedia.org/wiki/Chrząszcz
Unluckily I'm not able to fix it in my post thread
Unfortunately, browsers are stupid enough to expect non-ASCII characters to be percent-encoded in URLs. Hence it would be typical to see browsers, including the one you’re using to compose the link, borking at a structure like <A HREF="http://en.wikipedia.org/wiki/Chrząszcz">. It would have to be encoded as Chrz%C4%85szcz, I think.
