Redirection issue with some forum topics

Sometimes it happens that a topic is not accessible and the browser complains that the page is not redirecting properly. IIRC, I’ve encountered this problem a few times during the last weeks. I think it has to do with some special characters that have been used in the topic title.

I’ve added the modlook tag to such a topic I happened to encounter in my plugin’s support forum. I’m not pasting the link so as to avoid any URL encoding done by the browser when copying the URL.

Trying with curl results in a redirection loop:

Could a moderator or admin please check what might be causing it?

Thanks in advance.
