Oh yeah, a month ago I was reading a comment section about LLM writing tendencies and someone humorously suggested using the loooooooong-em-dash to distinguish yourself from LLMs. I found it so charming that I made my keyboard output it when I double tap "-".
On Linux you press Ctrl+Shifs+U and then type 2E3B, then press enter.
Wow, I'm impressed at your usage of this. Apparently it's 0x2E3B, named "three-em dash".
You must be human!
