So I tried editing Pokémon Emerald with adding the ´, that edit got through yesterday on PokéPark but reverted recently when I uploaded a better box art for it. The only reason I got was reading the style guide, which I did, nothing in it states anything about such things. I don't really see a reason for it to not be there, Pokemon games still shows up if I type Pokémon and the other way around. I also believe the search engine is better now in v3?
