What input method are you using such that this is even possible? Nearly all English speakers are using keyboards with a single apostrophe key which inserts \x27, and could not insert any of the other quote characters even if they wanted to. As a result, nearly all extant English-language text uses \x27 for both apostrophes and single quotes, and all this Unicode prescriptivism is describing a convention that is clearly not the one that English actually follows.
