Not to mention loanwords, which of course English is full of, and are sometimes considered properly spelt with their original accents, though many will spell them naïvely without.
Diphthongs too, especially in British English, are not just an archæological find, though out of pragmatism usually written digitally with two separate characters.
I find it most irksome that the Australian Labor Party has chosen the USA spelling in spite of being part of the Commonwealth.
I believe we can all still be confident scribes and maybe even have our own preferred way of writing words, where we within reason push the boundaries or push our own viewpoints through self expression :D
(Ironically, I'm not sure if deliberately ironically, you 'mispelt' both, fwiw.)
Thirtysomething here. I use diaeresis (a/k/a diæresis) over e.g. coöperate. It’s more concise than a hyphen. And it makes more sense than cooperate, given cooper is a word.
