I believe many people would not even consider it to be an alias, but just a spelling thing in combination with how the internet works. If you do not include stuff like ' in mapping, like you do with Capital letters, but need aliases, maybe just create automatic aliases for common spelling oddities like that almost whitespace character.
Or asked differently, how many people enter ' correctly in a search box? Propably as many or little as would search for Baldur's Gate, instead of baldurs gate, to cite another popular game with that problem.
