I checked around, and only found instances of the problem, but no encompassing message. There are many split characters, one with just their name, the other with a "The." For example, there is a "Riddler" and a "The Riddler," each with issues, description, etc. If you type in the word "the" you get a bunch of characters, usually with a small amount of issues attached to them. Maybe deleting/combining these could be someone's summer project?
Also some Mr./Mister Dr./Doctors, etc. may be out there.
