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.
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.
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.
