Demonyms are nouns used to denote the natives or inhabitants of a particular country, state, city, etc. So me are very quirky indeed. Any favourites? en.oxforddictionaries.com/definition/demonym In French, these are gentilés. Any other languages?

Some towns in France even have referenda about this.
I always liked the name for people from the Paris suburb of Créteil, which does not as such lend itself to being transformed into a harmonious name for its residents. So they are Cristoliens, which makes it sound like they work in a glass factory.
We're not as formalised or prescriptive about it as the French, but do have some that are a stretch from the working name of the place - Glaswegian, Mancunian, Salopian (I suspect some or maybe most of them are Victorian inventions by self-important city fathers).
And that's before you get to nicknames - Yellow-bellies, Monkey-hangers, Scousers, Mackems.
And football teams used to be nicknamed for the town's traditional principal product, like some school geography lesson - Hatters, Toffeemen, Blades, Cobblers.
I assume that Créteil straying a bit from the spelling may have had something to do with the proximity of the term crétin.
I can only think of three neighbourhoods in Paris whose residents have an official name, but I'm sure there must be more. People who live in Saint Germain-des-Prés are Germanopratins, people who live in Montparnasse are Parnassiens and people from Montmartre are Montmartrois. Naturally, just typing that made me think of Bellevillois, too.
Australian examples are very hit-and-miss. Tasmanians are sometimes Taswegians and the Northern Territory (TERRA-tree) is home to Terra-TORI-ans) Novocastrian exists only in quiz nights in Newcastle and no one believes Liverpudlian is really a word. Melbournians are the only ones who are posh enough to use their demonyn in conversation. Then again, there are perfectly good nicknames that are in use.

Aren't Liverpudlians usually Scousers? How about people from Blackpool?
Québec of course takes a very normative French approach, including researching the first names used for places. But nowadays some Indigenous people are questioning these names, saying that there were older names in use before French exploration or sentiment - problem is, often more than one Indigenous people has a claim to earlier names.
