I don’t know if it works on the Finnish keyboard, but when I switch to another Scandinavian language it’s still working fine.
On macOS, option-dash will give you an en-dash, and option-shift-dash will give you an em-dash.
It’s fantastic that just because some people don’t know how to use their keyboards, all of a sudden anyone else who does is considered a fraud.
Follow-up question: Do any mobile phone IMEs (input method editors) auto-magically convert double dashes into em-dashes? If yes, then that might be a non-ChatGPT source of em-dashes.
I'm on Firefox and it doesn't seem to affect me, but I'm pretty sure I've seen it in Safari.
And if you type four dashes? Endash. Have one. ——
“Proper” quotes (also supposedly a hallmark of LLM text) are also a result of typing on an iOS device. It fixes that up too. I wouldn’t be at all surprised if Android phones do this too. These supposed “hallmarks” of generated text are just the results of the typographical prettiness routines lurking in screen keyboards.
