Question mark (ConceptTopic, 5)
From Compile Worlds
Mysteriously, this page vanished when Kumizone was silently transferred to Keiji's awesome new VPS.
Detectives found traces of lol hackers in the transmission which unfortunately went unnoticed before now.Question marks are known to invade randomly, especially after having their dots stolen. Little was known about them before the page vanished, and even less is known now.
If you find a ??? on the ground you should check it out cause there very well might be a goblin hiding in there or a cutscene or even an item you need for your quest. Alternatively, it just might be a mysterious character.
The question mark even has a personification! She's called Hatena Yousei. Sadly, though, she wasn't created as such a personification, but that's what everyone sees her as now.
In MediaWiki
The question mark is one of a few characters (the others being the double quote, ", and the ampersand, &) to be allowed in page titles but mess everything up. If a question mark or ampersand is needed in a title, you can use the fullwidth versions ? and & to avoid the problem at the cost of aesthetics, for example Toadstool's ???. For double quotes, use smart quotes, “ and ”, for example Miles “Tails” Prower. All upmessing is an issue caused by MediaWiki (because as we all know by now, it sucks), and Keiji has a plan to fix this eventually.
