> Though I'm not sure who decided the ʻokina needed its own character rather than the traditionally used apostrophe. It's a pain to type without a Hawaiian keyboard.

I dunno, the glottal stop sounds pretty different from normal English usage of apostrophe. If anything it's closer to - than ', like in uh-oh.

French uses both grave and acute accent marks, and they sound very different.

Makes sense to me
