That is strange. One thing to add is that with no topic title, it has become extremely difficult to click any links to that topic. Even the one you provided has absolutely no way to click the actual topic link (which is dependent on the title length).
The first topic can be accessed all fine, but not the second one.
Seeing this can truly be trippy…
Also, sounds like a Discourse bug (I’m not sure though), if anyone can confirm that’d be great. I searched on the site, there has been no incident of this yet, but then again how do you search for a no-title topic lol.
Nope. You can use u+2800 in the title by pasting it a couple of times. The only possible error you can get is “Title seems unclear” but you can work around that that by including spaces in between. There definitely are ways to create an invisible title, but the one linked by the OP doesn’t have any title. It’s not invisible characters, just a bug where someone was able to create a topic without the “title” value being anywhere on the site.
That’s what I’m talking about. You can do it if you add spaces and make it “look” like a proper topic name (essentially making words out of the invisible characters). I’ve tried it before but for the sake of preventing clutter, deleted the topic.
Got it. For now I’ll consider this resolved, but you can file a new bug report again when you see another case and have clear steps to reach the repro case.
