I think this is cool and am happy to see the post to learn more about punctuation. LLMs have really brought the en/em (and beyond because there are so many) dash into the spotlight in a negative way. At a previous dev job I handled copy being sent for translation and got feedback from writers about inputting strings with the incorrect dash.

This is industry-standard punctuation with real use cases, obviously there's a saturation point but that is more LLM induced than anything else.

From a coding standpoint I'm surprised devs are not more interested in punctuation like this because there are so many different operators and syntax across programming languages.
